Abstract

The turbo charger admits air to the diesel engine and is driven by a shaft which is powered by a turbine. Exhaust gases from the engine power the expansion turbine. There is an air bleed from the air inlet to the engine this bleed being controlled by a throttle valve. The air is bled from the diffuser of the turbo charger and injected from the diffuser of the expansion turbine in order to give adequate control. The control of the throttle valve is linked mechanically to a governor, to maintain a constant speed of the turbo charger. The bleed air is injected between exhaust distribution blades (25) through an annular slot (27) from an annular chamber (26). The air is injected at a small angle to the exhaust flow and increases the speed of this flow.
