Date Apr. 18, 1991.This is a device for reducing gas exchange or pumping losses of an internal combustion engine having a throttle (1) for controlling the pressure in the inlet manifold for the combustion air with or without fuel to the cylinders of the motor. In the inlet manifold (20) to every cylinder there is provided a separate (1) throttle whereby the low pressure side of the inlet manifold relative to the throttle is supplied air or fuel-air mixture of higher pressure than the pressure of the low pressure side by a valve which at the start of every inlet stroke is kept open and which closes before the inlet valve of the engine closes with the closing function of the valve is actuated by the position of said throttle.
