COMPOUND SUPERCHARGING METHOD AND DEVICE

摘要

PURPOSE:To make it possible to drive the super-charger system, fully corresponding to the operating condition of the engine upon starting of the engine or upon excessive fluctuation of exhaust back-pressure, by coupling an exhaust gas turbine super-charger and an engine direct-coupled super-charger together in series. CONSTITUTION:The exhaust pipe 6 of an engine A is connected to an exhaust gas turbine 1. Feed-air enters into the blower 10 of an engine direct-connected super charger C which is driven by the crank shaft 8 of the engine from a blower 2 directly coupled to the gas turbine 1 through an air-cooler 7. Super- charged feed-air is introduced into the engine A through an air-cooler 7.
