What is the valve clearance of the Verna?

[DelCooper]

Verna valve clearance is as follows: intake valve 0.17-0.23mm, exhaust valve 0.22-0.28mm. Valve clearance is set to ensure the normal operation of the internal combustion engine's valve train. Since the valve train operates at high speed and high temperature, components such as valve tappets and valve stems will expand when heated, automatically pushing open the valves, causing the valves and valve seats to not close tightly, resulting in air leakage. Below is relevant information about valve clearance: 1. The side valve is structurally the simplest. Due to this valve design, the engine's anti-knock performance and high-speed performance are poor, so it is only used in engines with low compression ratios and low speeds. 2. The overhead camshaft valve is the most ideal in terms of performance. It can meet the requirements of current high-speed, high-compression-ratio, high-power models while maintaining good fuel economy, so it is widely used. 3. The bottom valve structure is more complex. Currently, it is only used in countries such as the United States and former West Germany's Italy.
