<p>PROBLEM TO BE SOLVED: To optimize an intake layout, to improve combustion using a pulsation effect, and to improve output torque by the combustion improvement. SOLUTION: An engine, a supercharger disposed in a midway part of an intake system communicating with the engine, and an intake valve for opening or closing downstream side end of the intake system are provided. In a maximum valve lift timing of the intake valve, pressure wave of the intake pulsation is made to reach the intake valve.</p> |
