  • Patent number: 5261231
    Abstract: The specification related to an intake/exhaust air pressure balancer connected to an intake apparatus and/or an exhaust apparatus of an internal combustion engine and a method of reducing the intake/exhaust air pressure resistance. The intake/exhaust air pressure balancer in this invention is essentially consisted of a storage tank and a bypass pipe. Minimization of an intake air pressure resistance can be achieved by temporarily storing an intaken air reversely flowed at the end of an intake stroke followed by reintake of the air into a cylinder during the next intake stroke, while minimization of an exhaust gas pressure resistance can be expected by temporarily storing a rapidly expanding exhausted gas discharged during an exhaust stroke followed by redischarge through an exhaust equipment under a reduced exhaust gas pressure.
