The main reason for causing the engine to "fly" is that the engine governor malfunctions or gets stuck in a high speed position; the intake pipe enters excess fuel or oil, such as the oil level of the wet air filter is too high or the glow plug valve of the diesel fuel fails Wait. When the engine "speeds up," it should quickly take the following measures: First, stop the oil supply. Move the speed control handle to the stop position quickly and pull the extinguishing rod to the stop position. If this does not work, use a wrench to unscrew the high pressure fuel line nut. (Single-cylinder only), stop the engine and stop the fuel supply. Second, stop the air supply. Air filter air inlet tightly wrapped with cotton or multi-layer plastic cloth, so that the engine due to lack of oxygen and flameout (this method is only used for the intake system sealed engine). Third, decompression. The engine decompression lever is rapidly brought to the decompression position, so that the engine is extinguished due to no compression. Fourth, increase the load. The tractor's engine speed, do not step on the clutch, but must step on the brake springboard to increase the engine load, so that the engine is extinguished due to overload. The above measures can be used singly or in combination, depending on the circumstances. The general principle is: the occurrence of "speed car" quickly stalled to reduce or avoid losses.
