Valve Introduction

The function of the exhaust valve is to discharge the burning exhaust gas and dissipate heat; the effect of the exhaust door is to discharge the burning exhaust gas and dissipate heat. The gap between the valve gap is too large: after the advancement, the exhaust valve is opened, the exhaust time is shortened, the opening height of the valve is reduced, and the normal air distribution is changed, so that the engine is insufficient in air intake, the exhaust is not clean, and the power of the exhaust is not clean. Decrease, in addition, the impact of the gas distribution mechanism parts increases and the wear is accelerated. Too small gaps: After the engine work, the parts are heated and expanded, pushing the valve away, causing the valve to close the strictness, causing air leakage, decreased power, and severely accumulating carbon or burning the sealing surface of the valve, and even the valve impact piston. The gas distribution mechanism with hydraulic pillar does not need to leave a gap.

Classification and cause of exhaust failure

1. The black smoke in the exhaust is mainly carbon particles that are not completely burned. Therefore, the amount of fuel supply system fuel is excessive supply, the air volume of the air intake system is reduced, the combustion room of the cylinder body, the cylinder head and the piston is poor, and the poor injection quality of the injector will incomplete the fuel.

2. The white smoke in the exhaust is mainly the fuel particles or water vapor that is not sufficiently atomized and burned. Therefore, all the fuel cannot be foggy.

The white smoke in the exhaust is mainly the fuel particles or water vapor that is not sufficiently atomized and burned. Therefore, any of the fuel cannot be atomized or water entering the cylinder will cause the exhaust to smoke.

3. The blue smoke in the exhaust is mainly the result of excessive oil into the burning room to participate in the burning. Therefore, the reasons that cause the oil into the combustion room will cause the exhaust to smoke.
