  • Two stroke internal combustion engine
    Patent number: 6874453
    Abstract: A two stroke internal combustion engine having a compressed air inlet port and an exhaust port the flow through which is controlled by suitable valves. Fuel is injected through a fuel injector. The timing of the opening of the valve is such that, as the piston approaches top dead centre and with the air inlet valve closed, the exhaust valve is closed such that some exhaust gas is trapped and compressed in the combustion chamber thereby increasing the temperature within the combustion chamber and hence facilitating ignition. The invention also contemplates initiating combustion before the air inlet valve is closed.

  • Engine with combustion and expansion of the combustion gases within the combustor
    Patent number: 6817185
    Abstract: An engine comprising an isothermal air compressor (1) into which liquid is sprayed as the air is compressed. A combustion chamber (4) receives and expands the compressed air from which the liquid has been removed, to generate power. A precompressor (21, 27) compresses the air upstream of the isothermal compressor. The compressed air from the isothermal compressor receives heat from the exhaust gas from the combustion chamber in a primary heat exchanger (3). A secondary heat exchanger (31, 45) transfers heat recovered from a part of the engine to the compressed air from the isothermal compressor (1) upstream of the primary heat exchanger (3).
