ABSTRACT:
A pulse balancing system is provided for a multicylinder two-stroke cycle internal combustion engine in which each cylinder is provided with its own mechanism for supplying an air-fuel mixture thereto. The vacuum pulse balancing system of the invention comprises a plurality of passages interconnecting each cylinder with one of the air-fuel mixture supply devices associated with one of the other cylinders, and one-way check valves provided in the passages. With the vacuum pulse balancing system of the invention, a vacuum pulse created by the piston in one of the cylinders is transferred not only to the air-fuel mixture supply device associated therewith, but also to the air-fuel mixture supply device associated with one of the other cylinders. This alleviates back pressure which may otherwise be caused in the air-fuel mixture supply device associated with the other cylinder due to the on-again off-again suction of air-fuel mixture therefrom to its associated cylinder.
