Turbo-compressed air and fuel supply system for gas fuel engine e.g. LPG

摘要

The system has a turbocharger with a turbine connected to the exhaust gas line from the engine and a compressor, with an inlet open to air source. A supply line for the compressed air has one end connected to the outlet of the first compressor and the other with an engine air inlet. A gas fuel supply line has one end connected with the source of the LPG fuel. A second and different turbocharger and a second compressor with has inlet, to which the gas fuel supply line is connected. A H.P. fuel supply line is provided, one end of which is connected with the outlet from the second compressor. Its other end is connected with the engine fuel inlet. A facility is provided for leading past amount of exhaust gas across the second turbine. An air pressure sensor is provided, capable of sensing the air pressure in the supply line for compressed air. A computer communicates with sensor and drain valve, and is able to control drain valve.
