The Deutz engine idled for a few minutes, and the valve emitted blue smoke. What happened? There's no smoke after refueling twice?

The engine emits blue smoke and basically burns engine oil. There are many reasons for this, roughly as follows:

The back pressure of oil return in the lubricating oil circuit of supercharger is too high. Check whether the supercharger leaks oil and the oil return pipe is blocked.

Second, the waste gas valve is damaged, and oil and gas cannot be separated and re-entered into the combustion chamber for combustion.

The oil seal of the three-valve is aged, damaged or damaged, and the gap between the valve and the conduit is too large.

Excessive engine oil exceeds the upper limit, which makes the crankshaft throw engine oil into the combustion chamber to participate in combustion at high speed.

5. The engine is badly worn, which leads to the excessive gap between the piston and the cylinder wall, and the oil enters the combustion chamber from the gap.

Six piston rings are stuck, and cylinder wall oil participates in combustion. This is why most cars burn engine oil.

Solution of engine oil combustion

Dismantling and overhauling the engine will destroy the sealing and accuracy of the engine. Moreover, it is possible to burn oil after tens of thousands of kilometers, so overhauling the engine is unsustainable.

With the progress of science and technology, the present maintenance-free technology is very mature and gradually recognized and accepted by the majority of car owners. It not only saves the cost of car maintenance, but also protects the original car parts. The company's exclusive patented technology, with nondestructive repair technology, can repair and release piston ring stuck burning oil during driving, with remarkable effect.
