Car Engine Tappet

What is a Car Engine Tappet?

A car engine tappet is a mechanical device that is used to open and close the valves in an internal combustion engine. The tappet is located between the camshaft and the valve stem, and it is actuated by the camshaft. When the camshaft rotates, it pushes on the tappet, which in turn opens the valve. When the camshaft rotates away from the tappet, the tappet closes the valve.

Types of Car Engine Tappets

There are two main types of car engine tappets: mechanical tappets and hydraulic tappets.

Mechanical Tappets

Mechanical tappets are the simplest type of tappet. They consist of a solid piece of metal that is shaped to fit between the camshaft and the valve stem. When the camshaft rotates, it pushes on the tappet, which in turn opens the valve. When the camshaft rotates away from the tappet, the tappet closes the valve.

Hydraulic Tappets

Hydraulic tappets are more complex than mechanical tappets. They consist of a plunger that is filled with oil. When the camshaft rotates, it pushes on the plunger, which in turn opens the valve. The oil in the plunger helps to cushion the impact of the camshaft, which reduces noise and wear. When the camshaft rotates away from the tappet, the plunger returns to its original position, which closes the valve.

Function of a Car Engine Tappet

The main function of a car engine tappet is to open and close the valves in the engine. The tappet is actuated by the camshaft, which rotates in time with the crankshaft. When the camshaft rotates, it pushes on the tappet, which in turn opens the valve. When the camshaft rotates away from the tappet, the tappet closes the valve.

Benefits of Using Car Engine Tappets

There are several benefits to using car engine tappets. These benefits include:

• Reduced noise: Hydraulic tappets help to reduce noise by cushioning the impact of the camshaft on the valve stem.
• Reduced wear: Hydraulic tappets help to reduce wear by providing a smooth surface for the camshaft to ride on.
• Improved performance: Tappets help to ensure that the valves open and close at the correct time, which improves engine performance.

Conclusion

Car engine tappets are an important part of the engine. They help to open and close the valves, which is essential for engine operation. There are two main types of tappets: mechanical tappets and hydraulic tappets. Hydraulic tappets are more complex than mechanical tappets, but they offer several benefits, including reduced noise, reduced wear, and improved performance.
