Lifters Car Engine

Introduction

Lifters are an important part of a car’s engine. They help to open and close the valves, which allow air and fuel to enter the cylinders and exhaust gases to exit. Lifters are typically made of metal, and they are located in the cylinder head.

There are two main types of lifters: hydraulic lifters and mechanical lifters. Hydraulic lifters use oil pressure to open and close the valves, while mechanical lifters use a camshaft to open and close the valves.

Hydraulic Lifters

Hydraulic lifters are the most common type of lifter used in car engines today. They are self-adjusting, which means that they do not require any maintenance. Hydraulic lifters use oil pressure to open and close the valves. When the engine is running, oil is pumped into the lifters. The oil pressure pushes the lifter against the valve, which opens the valve. When the oil pressure is released, the lifter moves away from the valve, which closes the valve.

Mechanical Lifters

Mechanical lifters are less common than hydraulic lifters. They are not self-adjusting, which means that they require regular maintenance. Mechanical lifters use a camshaft to open and close the valves. The camshaft is a rotating shaft that has lobes on it. The lobes push on the lifters, which opens the valves. When the camshaft rotates, the lobes move away from the lifters, which closes the valves.

Lifter Problems

Lifters can develop problems over time. Some of the most common lifter problems include:

* **Sticking lifters** can cause the valves to not open or close properly. This can lead to a loss of power and fuel economy.
* **Leaking lifters** can allow oil to leak into the combustion chamber. This can cause smoking and engine damage.
* **Worn lifters** can cause the valves to not seat properly. This can lead to a loss of compression and power.

Lifter Maintenance

Lifters should be inspected and adjusted regularly. The frequency of inspection and adjustment will vary depending on the type of lifter used in the engine. Hydraulic lifters typically do not require any maintenance, while mechanical lifters require regular adjustment.

If you are experiencing any problems with your car’s engine, it is important to have it inspected by a qualified mechanic. The mechanic can diagnose the problem and recommend the necessary repairs.

Conclusion

Lifters are an important part of a car’s engine. They help to open and close the valves, which allow air and fuel to enter the cylinders and exhaust gases to exit. Lifters can develop problems over time, so it is important to have them inspected and adjusted regularly.
