Judge the engine failure from refueling

Black smoke comes out when the engine starts, and black smoke comes out of the fuel outlet, accompanied by an explosion sound, indicating that the cylinder sleeve and piston are worn, as the cooperation gap is too large.
When the white smoke engine starts, white fog occurs rhythmically at the oil outlet. This is a precursor of the burning of tiles. High temperatures caused by dry friction before combustion caused a sharp rise in the local temperature of the oil, and a portion of the oil was evaporated from the crankcase. At this time, the machine must stop the inspection.
When the engine injects oil from the filling mouth during the work, not only the cylinder sleeve and the piston are very worn, but the piston ring may break or jam, The cylinder can be removed and the high temperature and high pressure gas of the combustion chamber produces a serious "bottom exhaust" phenomenon. At this time, the engine output decreased significantly and fuel consumption increased dramatically.
When the refueling hears a short "time, time" sound, the engine suddenly accelerates from idling, the sound is more obvious, the higher the speed, the louder the sound, the smaller or the sound disappears, the single cylinder will stop the engine (oil), Which can be judged as an abnormal sound of the connecting rod bearing. The gap between the connecting rod bearings should be considered. Excessive use or loose or defective connecting rod bolts should be avoided before use.
