Why does the oil port smoke?

The oil port smokes because the piston ring is not tightly sealed. When the combustible mixture in the engine explodes, it escapes into the crankcase through the gap between the piston ring and the cylinder block, and then smokes from the valve cover, dipstick sleeve and so on to the outside of the engine.

Treatment methods of automobile smoke and dust:

1. Check whether the engine cylinder block and cylinder gasket are damaged and whether there is water in the oil tank.

2, check the car manual, in strict accordance with the provisions of the manufacturer to add the correct label of gasoline.

3. Always check the aging degree of carburetor and other parts. Carburetor truck is different from EFI truck, so it should be maintained and adjusted frequently. Check the cylinder pipeline every 30,000 km and the spark plug every 1000 km. If there is any problem, replace it in time.

Precautions:

Because the engine speed is constantly changing, it is necessary to measure the load characteristics of the engine at different speeds in order to comprehensively evaluate the fuel economy of the engine at different speeds and different loads. The reading of engine load characteristics is carried out on the test bench.

Taking a gasoline engine as an example, after starting the engine, gradually open the throttle to the maximum, adjust the load, make the engine run stably at a certain speed, and measure the output power and fuel consumption of the engine under this working condition. Then turn down the throttle, adjust the load and keep the engine speed unchanged before measuring.
