If you’re trying to figure out what all the parts car do, you’ve come to the right place.
Have you ever opened your car’s hood and wondered what happens in there? A car engine can look like a big confusing jumble of metal, tubes and wires to the inexperienced.
You might want to know what’s going on simply out of curiosity. Or maybe you’re in the market for a new car and you’re hearing phrases like “6.2-liter V8,” “dual overhead cams” and “tuned port fuel injection.” What does all of that mean?
The purpose of this article is to help you understand the basic idea behind an engine and go into detail about how all the parts car fit together, what can go wrong and how to increase performance.
The purpose of a gasoline car engine is to convert gasoline into motion so your car will move. These days, the easiest way to create motion from gasoline is to burn gasoline inside an engine. Therefore, a car engine is an internal combustion engine – combustion takes place internally.
There are basic types of internal combustion engines: diesel and gas turbine engines. There are also HEMI engines, rotary engines and two-stroke engines, each of which has its own advantages and disadvantages.
There are also external combustion engines, the best examples of which are steam engines in old-fashioned trains and steam boats. The fuel (coal, wood, oil, etc.) in a steam engine burns outside the engine to create steam, which creates motion inside the engine. Internal combustion is much more efficient because it takes less fuel to propel the vehicle than external combustion. In addition, an internal combustion engine is much smaller than an equivalent external combustion engine. That explains why we don’t see Chevys or Fords using steam engines.
