Understanding the names of car engine components and their images can be beneficial. As is known, the car engine is a determinant of optimizing the car's performance and comfort during acceleration. By understanding the car engine components well, car owners will realize how important these components are, along with how to maintain them properly. Here are some engine components that you must know.

Essential Car Engine Components to Know

There are several car engine components that all car owners must know. Here are the complete names of the components.

1. Cylinder Head

The cylinder head component is installed together with the cylinder block and functions as a container for the four-stroke engine valve mechanism and a housing for the spark plug. 

2. Cylinder Head Cover

This component serves as a cover for the cylinder head.

3. Intake Valve

This component is part of the cylinder head. The main function of the intake valve is to open the air passage so that the engine combustion chamber can be filled with air according to its needs. 

4. Exhaust Valve

This component is also part of the cylinder head and functions to expel the leftover gases from combustion in the combustion chamber. The exhaust gases will then be directed to the exhaust and expelled.

5. Rocker Arm

The rocker arm component is still part of the cylinder head, functioning as a valve gap controller.

6. Camshaft

This cylinder head component functions as a controller and actuator for the intake and exhaust valves to open at the right time.

7. Intake Manifold

The function of the intake manifold component is as an air passage door when air enters the cylinder chamber.

8. Exhaust Manifold

In addition to the intake manifold, there is also an exhaust manifold that serves as the exhaust gas emission passage door from combustion in the combustion chamber, which will be expelled through the exhaust.

9. Spark Plug

This component from the cylinder head functions as a spark generator during the combustion process.

10. Cylinder Block

The cylinder block component serves as a support for several other engine components, ranging from gaskets, oil pulleys, drain plugs, flywheels, pistons, rings, pistons, to crankshafts. The cylinder block also functions as a pathway during the up-and-down movement of the piston.

11. Piston

The piston is a component of the cylinder block, which functions as a controller of the fuel combustion volume in the cylinder chamber.

12. Piston Ring

The piston ring functions to maintain the tightness between the piston and the piston ring wall to prevent leakage during the engine compression process.

13. Gasket

The gasket component serves to maintain the tightness of the joint between the cylinder block and the cylinder head. This way, the lubricant contained in the block and cylinder head components does not seep or leak.

14. Crankshaft

The function of the crankshaft component is to convert the up-and-down energy of the piston into rotational energy.

15. Drain Plug

The next component is the drain plug. This component functions to release engine oil when the car is undergoing an oil change.

16. Flywheel

The flywheel component serves to connect the engine energy to the clutch part to stabilize the engine rotation.

17. Push Rod

Functions to transmit the piston part to the crankshaft part.

18. Oil Pan (Carter)

Functions as a container for engine oil to keep the engine oil inside the car engine. Later, the oil will be used to lubricate and cool other car components.

19. Engine Pulley

Functions as a connector for clutch energy and as a storage place for engine energy. This energy will later be used to stabilize the engine rotation.

20. Carburetor

The carburetor component functions to control the mixture of fuel with air to achieve the right ratio so that the engine can operate optimally.

Thus, here are some names of the components in a car engine that you need to know. In fact, there are still many other engine components that have not been discussed. To ensure your car engine performs optimally, you need to regularly maintain the engine components.
