AUT1010 Module 2, Engine Types

It is important to understand that there are variety of engine types available, and each manufacture may do something slightly different. Even certain cars will have extremely different engine options available, such as the 2018 Ford Mustang with an Eco-Boost engine or the 5.0 L Coyote GT engine.

The first thing to be aware of when speaking about gasoline engine types: Carburetor or fuel injection?

With the onset of the ECU, the mid 1980s saw nearly all vehicles switch from carburetors to electronic fuel injection. While we will cover fuel injectors in greater detail during Module 5, for now, you simply need to understand that fuel injectors spray fuel into the air intake of an engine, or directly into the combustion chamber.

Most traditional engines are piston driven, however, there is also the Rotary engine which uses triangular cones that spin rapidly to propel a crankshaft, rather than pistons. Rotary engines are a little more unique, and will be discussed in great detail in the Advanced Automotive Technology course, AUT2010.

The most commonly seen engine is the inline 4-cylinder engine.  However, you can also find the inline-6 engine produced by AMC in the Jeep Wrangler and Cherokee lineups. Other common engines include the V6, V8, and V10 and V12 in some exotic vehicles and trucks.
