Introduction: The engine is the core component of the car and is called the "heart" of the car. A fully functional engine can ensure the smooth operation of the car, and the maintenance and replacement of engine parts are an indispensable part of car maintenance. Now we will introduce the main engine accessories in detail to help you better understand this key part of the car.

What are the engine spare parts?

1. Piston and piston ring

The piston is an important part responsible for reciprocating motion inside the engine. It is connected to the connecting rod and converts the energy generated by combustion into mechanical energy. The piston ring plays the role of sealing the combustion chamber, guiding the piston movement and dissipating heat.

2. Cylinder and cylinder head

The cylinder is the track for the piston movement and together with the piston constitutes the combustion chamber. The cylinder head is the upper seal of the cylinder, on which spark plugs or fuel injectors are installed, which is responsible for introducing the fuel and air mixture and discharging the exhaust gas after combustion.

3. Crankshaft and connecting rod

The crankshaft is a key component that converts the reciprocating motion of the piston into rotational motion. It is connected to the piston through a connecting rod, converting the up and down motion of the piston into rotational torque and transmitting it to the gearbox.

4. Camshaft and valve mechanism

The camshaft controls the opening and closing of the valve through the shape and position of its cam, thereby adjusting the timing and duration of intake and exhaust. The valve mechanism includes valves, valve springs and valve guides, which are responsible for controlling the in and out of the gas in the cylinder.

5. Turbocharger and radiator

The function of the turbocharger is to increase the intake volume of the engine and increase the power output. The radiator is responsible for dissipating the large amount of heat generated when the engine is running and keeping the engine operating temperature stable.

6. Fuel system

The fuel system includes fuel pumps, fuel injectors, fuel filters, etc., which are responsible for spraying fuel into the cylinder at high pressure and mixing with air for combustion.

7. Ignition system

The ignition system includes ignition coils, spark plugs, etc., which are responsible for generating high-voltage electric sparks at the end of the compression stroke to ignite the mixed gas.

The above is an introduction to "what are the engine spare parts". The diversity and complexity of engine accessories reflect the precision of modern automobile technology. Understanding the functions and effects of these accessories not only helps us better maintain and care for our cars, but also helps us more accurately determine the cause of the problem and make timely repairs when the car has problems. With the development of the automobile industry, the materials and designs of engine accessories are also constantly improving, contributing to the improvement of automobile performance and environmental protection.
