2. From a professional point of view, the higher the throttle opening, the higher the vehicle 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.
