Description of the engine components of the Toyota RAV4.

The Toyota RAV4 has several engine options, including a 2.0-liter 4-cylinder engine, a 2.5-liter 4-cylinder engine, and a hybrid 2.5-liter 4-cylinder engine. Here is a general breakdown of the engine components:

1. Air Intake System: The air intake system includes the air filter, which filters the air before it enters the engine, and the throttle body, which controls the amount of air that enters the engine.
2. Fuel System: The fuel system includes the fuel tank, fuel pump, fuel filter, and fuel injectors, which deliver fuel to the engine.
3. Engine Block: The engine block is the main component of the engine, and it houses the pistons, connecting rods, and crankshaft.
4. Cylinder Head: The cylinder head sits on top of the engine block and contains the valves and camshaft.
5. Exhaust System: The exhaust system includes the exhaust manifold, catalytic converter, and muffler, which help to reduce emissions and noise.
6. Cooling System: The cooling system includes the radiator, water pump, and thermostat, which help to regulate the engine’s temperature.
7. Electrical System: The electrical system includes the battery, alternator, and starter motor, which provide power to the engine and other components of the car.

These are just some of the basic components of the Toyota RAV4’s engine. The specific configuration of the engine will vary depending on the model and year of the vehicle.
