Car Engine Labeled

Engine Block

The engine block is the main part of the engine. It houses the cylinders, pistons, and crankshaft. The cylinders are where the fuel is burned, and the pistons are what move up and down to create power. The crankshaft is what converts the up-and-down motion of the pistons into rotary motion.

Cylinder Head

The cylinder head is located at the top of the engine block. It contains the valves that control the flow of air and fuel into and out of the cylinders. The valves are opened and closed by the camshaft.

Camshaft

The camshaft is located in the cylinder head. It is responsible for opening and closing the valves. The camshaft is driven by the crankshaft.

Crankshaft

The crankshaft is located at the bottom of the engine block. It is responsible for converting the up-and-down motion of the pistons into rotary motion. The crankshaft is connected to the transmission, which then transfers power to the wheels.

Connecting Rods

The connecting rods connect the pistons to the crankshaft. They allow the pistons to move up and down while still being connected to the crankshaft.

Pistons

The pistons are located inside the cylinders. They are what move up and down to create power. The pistons are connected to the connecting rods, which then transfer power to the crankshaft.

Valves

The valves are located in the cylinder head. They control the flow of air and fuel into and out of the cylinders. The valves are opened and closed by the camshaft.

Intake Manifold

The intake manifold is located on the side of the engine. It is responsible for bringing air into the cylinders. The intake manifold is connected to the carburetor or fuel injector.

Exhaust Manifold

The exhaust manifold is located on the side of the engine. It is responsible for carrying exhaust gases away from the cylinders. The exhaust manifold is connected to the muffler.

Oil Pan

The oil pan is located at the bottom of the engine. It is responsible for storing oil. The oil pan is connected to the oil pump, which then circulates oil throughout the engine.

Water Pump

The water pump is located on the side of the engine. It is responsible for circulating coolant through the engine. The coolant helps to keep the engine cool.

Fuel Pump

The fuel pump is located on the side of the engine. It is responsible for pumping fuel from the fuel tank to the carburetor or fuel injector.

Starter Motor

The starter motor is located on the side of the engine. It is responsible for starting the engine. The starter motor is connected to the battery.

Alternator

The alternator is located on the side of the engine. It is responsible for charging the battery. The alternator is driven by the crankshaft.

Power Steering Pump

The power steering pump is located on the side of the engine. It is responsible for providing power to the power steering system. The power steering pump is driven by the crankshaft.

Air Conditioning Compressor

The air conditioning compressor is located on the side of the engine. It is responsible for providing power to the air conditioning system. The air conditioning compressor is driven by the crankshaft.
