Abstract
1318788 Charging I.C. engines; gas turbine plant PLESSEY CO Ltd 19 Aug 1970 [8 July 1970] 33237/70 Headings F1B and F1G An I.C. engine includes an exhaust driven turbo-compressor 5, 6 Fig.1 and a duct bypassing the cylinders to pass air from the compressor to the turbine via a combustion chamber 13, having fuel injection and ignition means 14, 17, means independent of cylinder operation for starting the turbo-charger and feeding fuel to chamber 13, the line 7 from the cylinders to the turbine inlet having a valve 34, upstream of the junction with the by-pass duct, which during starting isolates the line from the by-pass duct and connects it to a substantially unrestricted exhaust outlet. Ambient air from inlet 4 is fed by the compressor 5 to inlet manifold 2a and exhaust gas leaving exhaust manifold 2b passes through the turbine 6 to outlet 8. A heat exchanger 26 may heat the air charge from the compressor or may warm air supplied to an air-pressurization and air conditioning system which is supplied with fresh air by a blower 25. The by-pass 12 leads from inlet line 3 through a valve 19 and combustion chamber 13 to exhaust line 7. An injection nozzle 14 is fed from a turbine-driven pump 15 through a valve 16 controlled electrically from a start-control unit 11 e.g. in response to a speed signal from the turbine. An ignition device 17 is controlled from the start control unit 11 which is also arranged to limit the temperature of the combustion gas and the turbine speed. A combined motor/ generator unit 18 acts as a motor to drive the turbo-compressor unit during starting and, when driven by the turbine, supplies current to the battery 10. During cranking the start control unit energizes the solenoid valve 34 into the broken line position in which exhaust line 7 is vented to atmosphere and isolated from the turbine and duct 12. During normal running the valve 19 isolates lines 3 and 7 from each other. In place of the electrical starting of turbocompressor 5, 6 a flow of air to drive turbine 6 may be derived from a reservoir 31 which is charged during a previous running period. In another embodiment the combustion chamber (23), Fig. 2 (not shown) is arranged to be traversed by the flow of exhaust gases from the engine.
