ABSTRACT:
A mechanical supercharger is provided in an intake manifold, and two inlet ports in communication with a cylinder are provided. A swirl control valve disposed in one of the two inlet ports is opened in a low speed/medium load region, and closed in a low speed/high load region and a low speed/low load region. Accordingly, scavenging performance can be enhanced in the low speed/medium load region where the pressure of a supercharged mixture flow is not sufficiently higher than the pressure of exhaust gas. In the low speed/high load region where the pressure of the supercharged mixture flow is sufficiently higher than the pressure of exhaust gas, undesired blowing of the mixture through a combustion chamber without being used for combustion can be suppressed while ensuring satisfactory scavenging, and an occurrence of knocking can be prevented.
