Claims

[Scope of utility model registration request]

an exhaust gas-driven supercharger driven by the exhaust gas of the engine; a mechanically driven supercharger driven by the engine via a mechanical transmission or by a starter motor of the engine; a first pipe line that leads air compressed by the exhaust gas-driven supercharger to the intake manifold of the engine; and a first pipe line that leads the air compressed by the exhaust gas-driven supercharger to the intake side of the mechanically driven supercharger. an engine supercharging device comprising: a second conduit for guiding compressed air; and a check valve disposed in the first conduit for allowing compressed air to flow into the intake manifold but prohibiting flow in the opposite direction. The check valve is provided close to the intake manifold, and a thin and short third pipe line for guiding compressed air discharged from the mechanically driven supercharger is connected to the check valve in the first pipe line. An engine supercharging device characterized in that it is connected to the downstream side of a valve.
