When water pump gasoline generator working, we sometimes can see blue smoke from the gasoline engine, what causes it? The blue smoke is actually caused by the burning oil in engine. For a four stroke engine, the oil and gasoline is completely separated. Although it is still inevitable that a small amount of oil will permeate the combustion chamber (i.e. oil consumption). But if to the exhaust emission blue smoke situation, it must belong to the engine fault category. Let's take a look at the structure of the engine to see which part of the engine is faulty. There are three rings at the head of the piston, and the upper two are gas rings to ensure the air tightness of cylinder and piston. The next one is the oil ring, which is used to scrape off the oil adsorbed on the cylinder wall. The gas ring is simply a circle, but not a whole circle, with a very small gap. One is to facilitate the installation; the other is to reserve the space for thermal expansion. It's lik...
