Why does Volkswagen Phaeton shift gears so fast?

1, from the professional principle, that is, the greater the throttle opening, the higher the speed;

2. The throttle of gasoline engine controls the throttle opening instead of the fuel injection quantity;

3, that is, the opening is small, and the mixed gas entering the cylinder is small, so that the power generated by the engine is small, and vice versa;

4. The more mixed gas enters the cylinder, the greater the force generated by combustion, so the greater the force to push the piston, the faster the piston moves, and the faster the engine rotates.
