摘要： In a four-stroke multicylinder internal combustion engine the exhaust space of each cylinder is connected to the intake of another cylinder out of phase with respect to the first by a half-cycle period via a communication pipe provided wwth nonreturn means. The underpressure due to the initial puff supercharges the second cylinder. Non-symmetrical nozzles constituting non-return means are provided in the exhaust space of each cylinder downstream of the mouth of the pipe in this exhaust space and in the intake space of each cylinder upstream of the position where the pipe opens into this intake space. Other non-return nozzles are arranged in the communication pipes. Each nozzle located in the exhaust space comprises an axial element having substantial thermal inertia and the pipe directs onto that element a flow of a fuel-air mixture having an adjustable air content, thereby reducing the atmospheric pollution. For increased efficiency, the nozzles may limit an annulus struck by the back flow and in which are provided inclined fins which cause rotation of said gas around the axis of this nozzle and prevent back flow from occuring. The invention is suitable for use in reciprocal piston and rotary piston engines.
