Typical 4 Cylinder Engine (click on engine
to start)
Note the easy to access layout of this engine,
an example of a good design. The oil filter, starter, Oxygen (O2) sensor
are located on the front side of the engine. Some notes:
The EFI on the back stands for Electronic
Fuel Injection.
Air enters from the air cleaner on the far
right (not visible) through the large black accordion tube, and through
the throttle body into the engine. Sensors measure the air flow, and throttle
pedal position, and a number of other factors, and control the amount of
fuel delivered to the engine through the fuel injectors.
