What will happen if Valin Hanma engine overspeed?

Hazard of excessive engine speed: 1. Excessive engine speed will often burn out the engine. 2. The engine speed is too high. From a professional point of view, the higher the throttle, the higher the speed. The throttle of a gasoline engine controls the throttle opening instead of the fuel injection quantity. That is, if the opening is small and the mixture entering the cylinder is small, the power generated by the engine will be small, and vice versa. The more air and mixed gas enter the cylinder, the greater the force generated by combustion, so the greater the force pushing the piston, the faster the piston moves, and the faster the engine speed. Generally speaking, low speed is good: fuel saving, low noise and long service life (low engine friction).
