摘要： PROBLEM TO BE SOLVED: To provide an engine with a supercharger for producing higher supercharging pressure.
SOLUTION: The turbo supercharger has two turbine scrolls V1c, V2c having mutually different distances to rotational centers (α1, α2) of a turbine wheel H. To the two turbine scrolls, the exhaust ports of cylinders having continuous ignition orders are connected. Thus, the scavenging operation of the cylinder in an intake stroke where preceding ignition occurs can be promoted by suction effects due to exhaust gas from the cylinder where following ignition occurs and exhaust gas from the following-ignition cylinder is given at the stage that exhaust gas from the preceding-ignition cylinder raises the rotation of turbines, therefore further increasing the rotating speeds of the turbines to produce higher supercharging pressure. Besides, the passage area of a nozzle on the side (V1c) of the following ignition order is reduced to reduce ill effects on scavenging operation.
