  • Patent number: 5282361
    Abstract: The present invention relates to a device for facilitating exhaust action of an internal combustion engine being used as a power-transmitting source of a vehicle, using a depression phenomenon resulted from induction and acceleration of air resistance due to forward movement of the vehicle (motor cars, vessels, airplanes or the like), thereby an output and a combustion efficiency of the internal combustion engine. To overcome problems of the forced exhaust method in the conventional internal combustion engine and improve the output and the combustion efficiency of the internal combustion engine, the present invention provides a device for facilitating exhaust action of the internal combustion engine comprising a guided flow depression device and a forced exhaust device, wherein combustion gases are exhausted by working fluids when the vehicle moves at a constant speed or more, and are exhausted by the forced exhaust device with the motor when the vehicle moves at a constant speed or less.
