How large is the Camry valve clearance?

Camry valve clearance, intake 0. 19-0.29mm, exhaust 0.38-0.48mm. The setting of valve clearance is to ensure the normal operation of the valve mechanism of internal combustion engine. Because the valve mechanism is in a high-speed state and the temperature is high, if the valve tappet, valve stem and other parts are stretched after being heated, the valve will automatically push open completely, which will make the valve and valve seat not close tightly and cause weather leakage.

Related contents of valve clearance:

1. The structure of the side valve is the simplest. Because the anti-knock performance and high-speed performance of the engine after adopting this valve form are poor, it is only used for engines with low compression ratio and low speed;

2. In terms of performance, the overhead camshaft valve is the most ideal. It can meet the requirements of high speed, high compression ratio and high power vehicles, and has good economy, so it has been widely used.

3. The structure of the bottom valve is complex, and it is only used in the United States, Italy, the former West Germany and other countries due to production habits.
