FIELD: engines and pumps.
SUBSTANCE: invention can be used in internal combustion engines with charge air cooler. Method of engine operation consists in increased flow rate of inlet air flow passing through heat exchanger (80), by closing valve (210), installed in intake tank (206) of heat exchanger (80) to direct air flow passing through the whole heat exchanger (80), so that it passes only through part of heat exchanger (80). Rate of inlet air flow is increased by controling position of valve (210) from open position whereat intake air entering into inlet tank (206) of heat exchanger passes through all cooling tubes (204) of heat exchanger (80), to closed position whereat intake air entering into inlet tank (206) of heat exchanger, passes only through part of cooling tube (204) of heat exchanger. Engine torque is maintained by adjusting position of throttle of inlet manifold and/or turbosupercharger bypass flap. Invention describes versions of the engine operating method.
EFFECT: high rate of intake air providing the required torque.
