Abstract

1,261,335. Charging I. C. engines. T. ZAKON. March 23, 1970 [April 16, 1969; Dec. 23, 1969], No. 13802/70. Heading F1B. A supercharged two stroke diesel engine has at least two turbochargers, comprising centrifugal compressors driven by essentially similar gas turbines, which deliver air to a common air receiver an auxiliary blower or low-pressure fan being connected in series with only one of the compressors, each gas turbine being fed by the same amount of exhaust gas and each compressor requiring essentially the same driving power, the delivery pressure of the auxiliary blower or lowpressure fan being chosen so that in operation all compressors not connected to it do not enter a surging regime. Centrifugal compressors 2, 4, Fig. 1 driven by gas turbines 3, 5 supply air to a common scavenge air receiver 7 from which the main diesel engine receives air. Compressor 2 receives air from an electric motor driven fan 1. The gas turbines may be driven by gases from separate or common gas manifolds. When fan 1 supplies compressed air to compressor 2 the rise of the delivery pressure from the latter causes the pressure and weight of air in receiver 7 to rise which results in an increase in the air delivered to the engine cylinders and in an increase in the exhaust gas flow. The mass of exhaust gas driving turbine 5 is greater than the mass of air delivered by the centrifugal compressor 4 and the speed of the turbocharger 4, 5 rises to supply air at a higher pressure. In other embodiments the compressor not supplied with compressed air from an auxiliary blower has a smaller diffusor and the air receiver delivers to under-piston pumps of the engine.
