Abstract
815,030. Two-stroke engines; cooling and pumping charge; valves and valvegear. BROWN, BOVERI & CIE A. G. March 11, 1957, No. 7934/57. Classes 7(2) and 7(6) In a two-stroke diesel engine 1, Fig. 1, supplied with air by an exhaust-driven turbo-charger 6 and an auxiliary compressor 7 in parallel through ducts 11, 10<SP>1</SP>, at starting, low load and, optionally, high load a valve 9 directs the compressor delivery to a nozzle 11 in the turbo-charger delivery and directed downstream thereof so as to prevent turbo-charger "pumping". Coolers 14, 14<SP>1</SP> and smoothing reservoirs 8, 4 are provided. The compressor 7 may be driven by an electric motor or a steam turbine at constant or adjustable speed, by a hydraulic or pneumatic motor or by the engine 1 or may be the underside of an engine piston acting as a pump. n Fig. 4 the nozzle 11 is in one limb 12" of a branched turbo-charger delivery 12<SP>1</SP>, 12", valves K\ K<SP>2</SP> and a valve K' in the compressor delivery 10<SP>2</SP> being in the positions shown at starting and low load, and the valves K<SP>1</SP>, K<SP>3</SP> open and the valve K<SP>2</SP> closed at high load. The valve 9 or valves K<SP>1</SP>-K<SP>3</SP> may be operated manually, directly or by mechanical remote control, or automatically. In Fig. 5 (not shown) the nozzle 11 delivers to the supercharger volute; in Fig. 6 (not shown) from the reservoir 8 to the engine cylinder inlet port belt under valve control and during scavenging only; and in Fig. 7 (not shown) to the inlet port belt from a pumping space under the engine piston and discharge from which is controlled by a spring- closed valve opened by abutments with the engine piston.
