Valves

In a diesel engine, valves regulate the intake of fresh air and the exhaust of burnt gases. Intake valves let in air during the intake stroke, while exhaust valves let out burnt gases during the exhaust stroke. These valves operate in synchronisation with the pistons and are controlled by the camshaft, which is essential for efficient engine operation.

Replacing or checking valves regularly is important because they are subject to wear and tear due to repeated movements and exposure to high temperatures. Worn valves can lead to various problems such as reduced engine performance, loss of compression, poor fuel efficiency and even serious engine damage. Checking the valves regularly and replacing them when necessary will help maintain proper engine performance and prevent unnecessary costs and downtime. This contributes to the safety and reliability of the vehicle or machine in which the engine is used.

When replacing valves, pay attention to manufacturer's specifications such as valve clearance and material. Check valve seats, seals, shafts and guides for wear and replace if necessary. Ensure correct timing of the valves in accordance with the camshaft. By following these steps carefully, you will maintain proper engine operation and reliability.
