Abstract

PROBLEM TO BE SOLVED: To reduce exhaust loss of an engine exceeding 30%. SOLUTION: An exhaust promoting device 1 to improve exhaust efficiency by applying the principle of a venturi pipe and utilizing outside air is attached at the outlet of an exhaust pipe 2, exhaust efficiency is improved, and incurring of an exhaust loss is reduced. Namely, air entering a device to improve the exhaust efficiency of an engine during running is brought, in the position of the exhaust pipe 2, into a negative pressure through the principle of a venturi pipe. Thereby, exhaust resistance is reduced and incurring of an exhaust loss is also reduced. Further, since during running of a vehicle, air is worked as resistance, the more a vehicle runs at a higher speed, the more resistance is also increased. By reversely utilizing air being the resistance, with an increase in the running speed of a vehicle, the effect is improved.
