Not So Fun in the Sun: Summer Engine Troubles

May 18th, 2013

 

summer sun

Heading to the beach this summer? Don’t let your car overheat. Oh, and watch out for sand, too.

Whether you like hot weather or cold, you have to recognize that summer is coming.  And with it comes picnics, pool parties, barbeques, and summer car trouble.  Yeah, winter doesn’t bring the only seasonal car problems.  Freezing engines in the winter, pollen in the spring, and heat in the summer.

 

What Summer Does to Your Car

 

The most obvious problem is, of course, overheating.  But we’ve discussed previously what you can do for an overheating car.  But one major problem you may not think of offhand is your battery.  In the summer sun, battery fluid can evaporate on couplings and corrode the material.  Make sure you check your battery for leaking fluid.

Another part of your car to watch out for is the engine.  Make sure all its fluids are full, to keep the engine lubricated and the coolant flowing.  You may want to flush your coolant system to make sure it’s running properly.  And while you’re at it, check the air conditioning to keep from overheating yourself.

Also, beware of the tires.  If your tires aren’t inflated enough, they’ll create more friction with the road, become increasingly hot, and may well blow out.  As if decreasing your speed and maneuverability wasn’t bad enough.

As a last caution, remember to keep your car washed and waxed if you want it to look its best.  UV rays are bad for both your skin and your car’s exterior.

As long as you’re careful, you shouldn’t have major problems over the summer.  In fact, that holds true for more than just your car.  So have a good time this summer without car breakdowns.

The Mechanics of Finding Good Mechanics

May 17th, 2013

 

A good mechanic is a great find and a bad thing to lose.   Not everyone has the time, knowledge, or experience to take care of their engine themselves.  But if you’ve moved, your mechanic has left, or any number of things that mean you’re short a mechanic, there are ways to find one.

 

Fixing Your Engine

Your mechanic will keep your car running like a well oiled machine. Because when he’s through with it, that’s what it’ll be.

Of course, everyone’s favorite place to look is the internet.  Use caution when searching on Google or any other public forum; you’ll find lots of results but many of those might be from people who were really just having a bad day and wanted to complain.  However, if you notice that someone takes the time to respond to reviews online, that’s a good sign that they actually care about their customers.

 

Driving past mechanic shops is a good way to scope them out – do they have a lot of customers or a few, and are they finishing the cars on the lot quickly?  Do they keep a clean shop?  If not, that filth and grime might end up on your engine.  Classic cars in the yard indicate that they take time and caution on the autos in their care.  They may also specialize in a particular type of car, which would be helpful to know before hand.

 

Word of mouth is, of course, always an excellent way to sort out the good mechanics, particularly if you ask those who tend to know a thing or two about cars.  Taxi drivers and chauffeurs, and other people who make their living with cars, will be likely to know where you can find a good, reliable mechanic.  Local car clubs will also prove helpful in that respect.

 

When you find a good mechanic, give them a test drive, so to speak.  Take your car in for a minor repair, which will let you gauge their services and prices as well as give you a chance to meet the mechanic in person.

That may seem like a lot of steps, but it’s really not too difficult.  And in the end, finding a good, reliable mechanic who won’t overcharge you will be worth it.

Receiving Transmissions

May 1st, 2013

 

transmission gears

These little gears are what keeps your engine from outpacing your wheels.

Quick post for today: Ever wondered what a transmission does for your car?  How it works with your engine?  It’s pretty simple; the transmission’s function is to convert speed and torque.

 

Speed and Torque

 

When your engine starts to turn, it’s quickly up to high rotational speeds.  However, the wheels don’t get up to speed quite so quickly.  Or at least, if they tried, they’d get shredded.  After all, the engines are just moving pistons, while your wheels need to drag a ton of metal into action, which takes a lot of initial force.  However, the engine doesn’t work at slower speeds and needs to rotate freely.

The transmission is made up mostly of gears.  The special thing about gears is that they can change rotational speeds – perfect for changing the speed between engines and wheels.  The transition is controlled by a flywheel, clutch, or fluid coupling.  The transition has multiple gears of different sizes for different engine rotations.  Then it’s just simple switching and your car can go whatever speed you want.

BMW: German Engineering Genius

April 22nd, 2013

 

BMW logo

A company with a long history of quality engines, BMW is still making spectacular cars today.

Say what you like about buying American, the German auto market produces some of the best and most well-known cars on the market today.  Particularly luxury cars – BMW, Audi, and Mercedes-Benz are the three German companies who have a global corner on the luxury car market.  But where did BMW come from?  And what does that stand for, anyway?  Well, hold on to your seats (or the steering wheel, but if you’re driving, you shouldn’t be reading this), because here’s a brief history of BMW, or the Bayerische Motoren Werke company.

 

Beginning of the Company

 

Yes, the real name of BMW is that long and German.  They’re a German company, after all, based in Munich, Bavaria, Germany.  The English translation happily keeps the same initials, though: Bavarian Motor Works, which is much easier to pronounce.  The company, interestingly, started in the same field as the Lincoln Motor Company, and at about the same time.  In 1916, the Rapp Motorenwerke company started building engines.  Not for cars, though; these engines were for aircraft.  For WWI, in fact.  The first engines were shaky, but RM soon updated their engines and were doing quite well.  Too well, actually; they grew too quickly, and before long, they were having financial difficulties.  Rapp, the owner for whom the company was named, resigned.  Two Austrians took over, merged with a local small aircraft maker, and named the company Bayersiche Flugzeungwerke.  This changed quickly to the current name, and BMW came into existence, building high quality aircraft engines for the war.

This went well until WWI was over and the Armistice Treaty stipulated that BMW stop producing airplanes.  Not to be daunted, or put out of business for too long, BMW began building motorcycles.  The R-32, the first BMW motorcycle, was announced in 1923.  The basic design for this compact cycle was so effective that the theory is still used in their motorcycles today. In 1928, BMW began building cars called the Dixi 3/15 PS, under license from Austin.  The car was updated in 1929 and 1930.  The first car they built entirely came in 1932, the BMW AM 4.  With a 4-cylinder engine, suspended valves, and two chains driving the crankshaft, the “Ausfuhrung Munchen 4 Gange,” or AM 4, produced 20 horsepower at 3500 rpm and hit a top speed of 50 miles.

Their most famous pre-WWII car was the BMW 328.  Built as a motor sport vehicle, the 328 made significant improvements on previous cars.  The engine was an in-line 6 cylinder, giving 80 horsepower, 5000 rpm, and with a top speed of 93 mph.  It quickly became a popular car for the road, though the 328 did make a name for itself on the track, as well.

Before long, war broke out again, and BMW found aircraft engines in demand again.  They began providing engines to the Luftwaffe until the end of the war, when they once again were banned from making aircraft engines for 30 years.

 

Mid-Life Crisis

 

After the war and with aircraft engines off the market, BMW turned  luxury cars and produced the 501 luxury sedan.  However, a luxury car in post-war Germany wasn’t what the general populace was looking for, so the sales weren’t what BMW hoped for.  So they turned their hands to making the popular economy cars.  BMW acquired the rights to the Iso Isetta and powered the cars with their motorcycle engines.  These small cars helped the company regain finances and property, and soon they were turning out more cars; and selling cars and buying companies overseas, like the Rover series which they later sold to Ford.

 

Where are they now?

 

BMW continues selling high quality luxury cars, competing with Mercedes and other companies to produce newer, better, faster, and more efficient cars every year.  In June 2012, Forbes magazine listed BMW as the #1 most reputable company worldwide.  Where is BMW now?  Quite well off and continuing to improve.

Reduce Reuse Recycle

April 11th, 2013

 

If your car has completely gone to scrap but you feel bad about just dumping it, there are a few things you can do to be more environmentally friendly.  If it’s just the engine that’s gone, of course, buying a used engine is one of the most ecologically friendly ways to get your car up and running again, but if it’s more than that, there are some things you can do.

 

Safety Hazards and Little Leaks

 

old car

Let your old car come to life again and let its parts be used for something new.

There are still a lot of things hiding inside of your car that can be harmful to the environment.  This particularly includes large amounts of fluid waste: antifreeze, oil, gasoline, wiper fluid, and other liquids that kept your car running smoothly previously are now little more than possible hazards.  When you’re ready to  dispose of your car, make sure you check rules and regulations regarding proper care and recycling methods.

 

Car Recyclers

 

There are many websites and charities that accept cars for recycling.  Some charities can use them, and in some cities, junkyards will pick up your car free of charge.  Again, following the above link will help find recycling centers near you.

 

Why Recycle?

 

Each year, somewhere around 10 million vehicles in the United States alone are disposed of, and approximately 95% of those cars are recycled.  75% of the materials in those cars are completely re-used.  So what does get recycled?

First, there’s the metal.  Cars have a good deal of metal in them, and metal is a premium product on the world market.  With a bit of care, most of the metal in the car you recycled can be re-used for wires, metal plating, pipes, or anything else you can imagine.

Next is the battery.  Many cars use lead-acid batteries, and recycling programs for these have long been in use.  In fact, nearly all car batteries are re-used in new car batteries.

Other commonly recycled parts are the car’s tires.  Aside from being used for swings over a river, the rubber in car tires is put to new use in anything from playground treading to pavement to providing fuel for kilns.

As for all of those previously mentioned fuels, those can be cleaned and recycled or used as alternate fuel sources if you drop them off in the right places.

 

Why recycle?  Because recycling uses much less energy than creating or mining new materials, makes use of what we already have, and saves money, too.  Because even if 95% of old cars are recycled, that’s still half a million cars every year that completely go to waste, fill up landfills, and leak toxic waste into the soil.  Because recycling your car keeps this planet just that much safer.

What Do Engines Do? Part 4: Having Trouble?

April 3rd, 2013

 

car engine

Although the theory is simple, making an engine work requires a lot of very precise pieces. Really, if you think about it, it’s a wonder they work so often!

If you hopped in your car and turned the key but nothing happened, or if you suddenly started seeing smoke pouring out of your hood, or if your engine has ever sputtered and died, you might have a bit of a problem.  You see, engines aren’t really supposed to do any of those things (in case you haven’t heard).  But they do.  What do you do when your engine goes kaput?

The first thing to do is determine where the problem originated, and when the problem occurred can help solve that.  Here are a few common troubles your engine might face.

 

 

Engine Shut Down on Start Up

 

 

There are several reasons your car might not start up instantly.  For example:

- No Charge in Battery – If your battery was running all night or something else drained it, it won’t be able to turn your engine over.  You’ll need to give it a jump start.

- Signs of Wear and Tear – If your battery cables are corroded or came loose, or if your oil filter or air filter are clogged, or your ignition switch joggled loose, or even your spark plugs are worn out, you won’t be able to get a response from your car.  Proper engine maintenance should solve, or even prevent, such problems.

 

 

Pull Over

 

If a hot engine is giving you trouble on a trip, chances are it’s overheated.  This one is the most likely to happen after you’ve started up.  If your engine is overheating, take the proper steps to take care of it (see link above), and you’ll be on your way again soon.

 

Other issues that might crop up to mess with your engine include bad fuel mixes, lack of adequate compression by the pistons, misfiring spark plugs, or cut wires.  All of these can damage your engine, and most likely put a big dent in your day, although hopefully not your engine.  Drive carefully and be safe, and may your engine last a long time.

What Do Engines Do? Part 3: Turn the Key

March 30th, 2013

 

You step into the car and turn the key.  Nothing happens.  Which is when you realize that your headlights were on all night and your battery is drained.  Now your car will never start!  But wait… why do you need the battery to start the car anyway?

 

The Key to the Engine

 

After all, a car engine is mostly self-sustaining.  The crankshaft turns because of the power provided by spark plugs igniting fuel and driving down pistons.  There’s no electricity in any of that.  But here’s the thing – you need to “turn it over” before the engine can start moving itself.  So the process when you turn the key is simple.

 

A Bit of Battery

 

The key turning sends a signal to the Starter Solenoid.  This pulls energy from your battery to the starter motor.  On the starter motor, a small gear spits out and turns quickly, making the large flywheel rotate.  The flywheel is connected to the crankshaft, which is connected to the pistons.  As the flywheel turns and the crankshaft rotates, pistons are pulled downward which makes the cylinders take in air.  The air is combined with gas, compressed, sparked and exploded, the pistons are shoved down, and there you go, your engine is up and running!

 

Power Down

 

When you turn the engine off, it disengages the spark plugs.  No more spark means no more explosions, no more explosions mean no more power, and no more power means your car can stop.

 

There you have it, the basics of turning cars off and on, and how your engine runs.  Also, the importance of your car battery – if you don’t have a battery, your flywheel is going nowhere.  But that’s not all there is to an engine – things go wrong.  What happens when they do?  We’ll be back with more on that next time.

What Do Engines Do? Part 2: Conversion

March 27th, 2013

 

If you’re like most people, you’re used to jumping in your car and turning it on, without a thought to how the engine makes everything work.  If you want to find out how this actually works, well, that’s what we’re discussing now.  In our last post, we talked about how pistons turn energy from gas into movement.  This time, we’re talking about how that up-and-down movement from the pistons becomes the circular movement needed for wheels to move.

 

Time to Get Rolling

 

Crankshaft

 

The crankshaft is inside of the engine, connected to the pistons.  The pistons can rotate on both ends, allowing them to move smoothly up and down despite the crankshaft at the end.  As the piston moves around the rotating joint on the far end, it circles the axis formed by the crankshaft, allowing the up-and-down motion of the piston to become a circular motion, as carried by the crankshaft.

The crankshaft is also connected to the camshaft (the part that controls the intake valves), so that the two rotate in synch with each other constantly.

 

Drive Shaft

 

Not to be confused with a crankshaft, the drive shaft runs the length of the car.  Once the vertical motion of the cylinders and pistons is converted to rotational movement through the crankshaft, the drive shaft takes this movement along to the wheels.  They turn, the car moves forward, and there you have it – locomotion.

The turning drive shaft also runs the length of the car, allowing the wheels to turn.

What Do Engines Do? Part 1: Combustion

March 22nd, 2013

 

Time to go take the kids to the big soccer game.  You gather the stuff, hand out the soccer balls, make sure everyone has cleats and jerseys, almost forget your keys, get them, hop in the car, refuse yet another bathroom request or you’ll be late, and turn the key.  Your car roars to life and you back out of the garage and get to the game with seconds to spare.

 

Of course, you expected the car to start.  Those (hopefully) rare days when the car revs and dies or doesn’t even start are generally the start or cause of a rather miserable day.  Having reliable engines is definitely a good thing.  But how does it work, anyway?

 

The Engine:  The Power Behind Your Car

 

 

Engine Basics

 

 

car engine

Here it is: the powerhouse that gets you where you want to go. All hail the convenience of engines!

For simplicity’s sake, we’ll just discuss the internal combustion engine that comes standard in most cars.  The basic idea of an engine is to release the energy stored in gasoline (or whatever fuel source you’d like to use), harness that, and translate the energy into motion.  This process starts out in a method rather like launching a potato gun, or using alka seltzer to turn a film canister into a rocket.  (If you don’t know what a film canister is, I pity you.)

 

For all of these examples, the motion comes because tightly compressed spaces with the right kick tend to expand explosively.  This expansion provides propulsion for whatever nearby surface can be prevailed upon to move.  In the case of a potato gun, you might get a bit of a nasty kick from the tube but the potato gets most of the force and goes rocketing away.  A film canister presses the lid to the ground, can’t expand more that way, and shoots the rest of the canister into the air at high speeds.  Expanding gas in an engine pushes pistons and voila, movement!

 

More Details on Piston Movement

 

Here’s what happens specifically.
You’ve got a cylinder with two injectors at the top.  One puts fuel into the engine while the other lets air in as the piston moves downwards.  The piston comes up again to compress the air and gasoline, and when it reaches the apex of its movement, the spark plug ignites the gas mixture.  This explodes with force, pushing the piston down.  The piston returns to the top to expel the exhaust, then the process starts over.  Therefore, the piston moves down and up again twice for each cycle.  To visualize, this page has a handy diagram of engine pistons.

Don’t forget that this entire cycle happens about 500 times a minute when your car is in motion, give or take depending on your car’s specs.

 

Later, we’ll talk about how combustion turns into motion.

The Life and Times of Lincoln

March 20th, 2013
lincoln

No, the other Lincoln. The one that has an engine.

If you’re expecting log cabins, philosophical debates, civil wars and assassinations, you might want to think again.  This is a used engine site, not a history class.  Also not to be confused with the history of the Lincoln Motor company that produces non-automobile motors, this is the history of the Lincoln auto company.

 

Birth and Young Life

 

The Lincoln Motor Company was founded in August 1917 by a father-son duo, Henry and Wilfred Leland.  Henry Leland had previously been a manager for Cadillac, but wanted to work at creating aircraft engines for  the Liberty planes of World War 1.  He named his company after his hero, for whom he had voted – Abraham Lincoln.

Shortly thereafter, the war ended, and the new Lincoln Motor Company needed to find something new to work on, so they turned to manufacturing luxury cars.  In 1920, the first luxury Lincoln rolled off the line and onto the streets.

 

Mergers and Moving Up

 

Unfortunately for the Leland’s little company, the Lincoln L-Series didn’t exactly explode on the car market.  Rather, it exploded in the company’s face.  Only about 150 cars were made before the company had to declare bankruptcy.  However, it wasn’t all gone.  The company was, instead, acquired by the very people who had provided them cylinders for their aircraft engines – the Ford Motor Company.

Before long, the Lincoln was not only a well-known luxury car, but was, in fact, up at the leading edge of the luxury market.  In fact, in 1940, the Lincoln Continental became the first vehicle to win an award for design excellence from the Museum of Modern Art in New York, and artist/architect Frank Lloyd Wright declared it the “perfect car.”

 

Brand Progression

The four-pointed star of, as it says on the label, the Lincoln Motor Company.

In 1927, the brand image for the Lincoln was a greyhound hood ornament.  In the ’30s, though, Ford began using a coat of arms, and Lincoln followed suit, with a coat of arms bearing a red cross and knight’s helmet.  Eventually, the symbol evolved to become the framed, 4-pointed star that still exists today.

 

Present Day Lincoln Motors

 

Like all car companies, Lincoln Motors has had ups and downs.  Their best-selling years came in the late 1980′s to early 90′s, but the downturn of the economy hit them like it hit the rest of the USA.  In 2002, Lincoln Motors had to declare bankruptcy, but were revived, again, by Ford.  At present, the company is planning new models and hopes to release them by 2015, which they believe will spur increased sales and productivity.
