This is a composite supercharging system in which second-stage air compression is performed by a turbo supercharger directly connected to the engine, and the compression ratios on the suction side and the discharge side of both superchargers are configured to be almost the same under the engine's rated output state.

Claims

[Scope of utility model registration request]

In a 4-cycle diesel engine, the exhaust gas turbine supercharger performs the first stage air compression, and the engine-directly connected turbo supercharger connected in series to the air system of the turbocharger performs the second stage air compression. This is a composite supercharging system in which the compression ratios on the suction side and the discharge side of both superchargers are made almost the same under the engine's rated output state.
