## Parts of an Engine Car
### 1. Engine Block
The engine block is the main structural component of the engine. It houses the cylinders, pistons, crankshaft, and other critical components. The block is made of cast iron or aluminum and is typically bolted together in two halves.
### 2. Cylinder Head
The cylinder head is located at the top of the engine block and forms the combustion chamber. It contains the valves that control the flow of air and fuel into and out of the cylinders. The cylinder head is also responsible for cooling the engine by circulating coolant through it.
### 3. Pistons
The pistons are cylindrical metal components that move up and down within the cylinders. They are connected to the crankshaft by connecting rods. The pistons compress the air and fuel mixture in the cylinders and then transmit the force of the combustion to the crankshaft.
### 4. Crankshaft
The crankshaft is a rotating shaft that converts the reciprocating motion of the pistons into rotary motion. The crankshaft is supported by bearings and is connected to the flywheel, which helps to smooth out the engine’s operation.
### 5. Camshaft
The camshaft is a shaft that controls the opening and closing of the valves in the cylinder head. The camshaft is driven by the crankshaft and is typically located in the engine block or cylinder head.
### 6. Valves
The valves are located in the cylinder head and control the flow of air and fuel into and out of the cylinders. The valves are opened and closed by the camshaft.
### 7. Oil Pump
The oil pump circulates oil through the engine to lubricate the moving parts. The oil pump is typically driven by the crankshaft.
### 8. Water Pump
The water pump circulates coolant through the engine to cool it. The water pump is typically driven by the crankshaft.
### 9. Intake Manifold
The intake manifold is a passageway that directs air and fuel from the carburetor or fuel injector to the cylinders. The intake manifold is typically made of aluminum or cast iron.
### 10. Exhaust Manifold
The exhaust manifold is a passageway that directs exhaust gases from the cylinders to the catalytic converter and muffler. The exhaust manifold is typically made of cast iron or steel.
### 11. Flywheel
The flywheel is a heavy metal disk that is attached to the crankshaft. The flywheel helps to smooth out the engine’s operation and provides inertia to help the engine start.
### 12. Starter Motor
The starter motor is an electric motor that is used to start the engine. The starter motor is typically located on the side of the engine and is engaged with the flywheel when the ignition key is turned.
### 13. Alternator
The alternator is a generator that converts mechanical energy from the engine into electrical energy. The alternator is typically located on the side of the engine and is driven by a belt. The alternator provides power to the battery and to the electrical components of the vehicle.
### 14. Battery
The battery stores electrical energy and provides power to the starter motor and electrical components of the vehicle when the engine is not running. The battery is typically located under the hood of the vehicle.
