Abstract: 1534576 Turbocharged I.C. engine power plants FRANCE ARMED FORCES MINISTER OF 21 April 1976 [24 April 1975] 16211/76 Heading F1B A power-plant comprises an I.C. engine 10 (preferably a diesel with a compression ratio of 12) and an exhaust driven turbocharger 11, 12, 13 wherein charge air from a compressor 12 passes through a heat exchanger 17, for heating by gases exhausted from the turbine and through a cooler 27, the pre-heated charge air also passing by an engine by-pass 20 to an auxiliary combustion chamber 22 upstream of the turbine 12. At starting the turbo-compressor is cranked by starter motor 15, and fuel is supplied to the auxiliary combustion chamber 22 while the cooler 27 is inoperative and hot air passes via a by-pass 29 to heat the engine intake 19 and cooler 27. When the temperature and pressure of the supercharged air are sufficient to ensure self-ignition, the engine 10 is cranked and started. Cooling the charge-air then begins as engine load or speed is increased and is controlled by rotating a fan 23 via a variable speed transmission 24 in dependence upon intake temperature and pressure sensed at 26 and ambient temperature sensed at 26a. As the engine load builds up, there comes a point where the compressed charge air leaving the compressor 11 is hotter than the turbine exhaust gases so that the heat-exchanger 17 acts as a charge cooler. The charge air cooling can also be controlled by using coolant pumped by an engine operated pump optated by a variable transmission, or without a variable transmission if a controllable coolant flow throttle is provided.
