What are the car engine parts?

The automobile engine is the core component of the automobile and consists of many parts. The design and manufacturing of these parts play a vital role in the performance and life of the engine. In this article, we will take a closer look at all the components of a car engine.

1. Cylinder block and cylinder head

The engine cylinder block and cylinder head are one of the important components of the engine. The cylinder block is the main structure of the engine and is responsible for supporting all parts of the engine. There are several cylinder holes inside the cylinder, usually 4, 6, or 8, for installing pistons. The cylinder head covers the top of the cylinder block and seals the cylinder block and valve train. There are valve holes, spark plug holes and intake manifold holes on the cylinder head.

2. Pistons, connecting rods and crankshafts

Pistons, connecting rods and crankshaft are the three important components of an engine. The piston moves up and down in the cylinder bore and is connected to the connecting rod, converting the linear motion of the piston into the rotational motion of the connecting rod. The connecting rod transmits the motion of the piston to the crankshaft. The crankshaft is the main shaft of the engine and is responsible for converting the rotational motion of the connecting rod into the engine's output power.

3. Valve mechanism

The valve mechanism is an important part of the engine and is responsible for controlling the opening and closing of the valves. The valve mechanism includes camshaft, valve, valve spring, lifter, etc. The camshaft drives the valve through the crankshaft. The valve spring is responsible for returning the valve to ensure the normal operation of the valve.

4. Ignition system

The ignition system is an important part of the engine and is responsible for igniting the mixture. The ignition system includes spark plugs, ignition coils, ignition controllers, etc. The ignition controller detects the working status of the engine through sensors, controls the ignition time and ignition intensity, and ensures the normal operation of the engine.

5. Air intake system

The air intake system is an important part of the engine, responsible for mixing air and fuel and sending them to the engine for combustion. The air intake system includes the intake manifold, throttle valve, air filter, etc. The intake manifold introduces air into the engine, the throttle adjusts the air flow, and the air filter filters impurities in the air to ensure the normal operation of the engine.

6. Cooling system

The cooling system is an important part of the engine, responsible for dissipating the heat generated by the engine and maintaining the normal operating temperature of the engine. The cooling system includes water pump, radiator, water tank, etc. The water pump circulates the coolant into the radiator, the radiator dissipates the heat through the heat sink, and the water tank is responsible for storing the coolant.

7. Lubrication system

The lubrication system is an important part of the engine and is responsible for reducing friction and wear of engine components. The lubrication system includes oil pumps, oil filters, oil radiators, etc. The oil pump circulates the oil into the engine, the oil filter filters impurities in the oil, and the oil radiator distributes the oil through the heat sink.

Car engines are complex mechanical systems made up of many parts. The design and manufacturing of these parts play a vital role in the performance and life of the engine. The cylinder block and head, pistons, connecting rods and crankshaft, valve train, ignition system, air intake system, cooling system and lubrication system are the main components of the engine. Only when these parts work together can the normal operation of the engine be guaranteed.
