Abstract

DC60 (25/09/55) Exhaust ventilation system for improving torque characteristics of spark ignition engines. Four-stroke, single-cylinder The exhaust system consists of a header pipe (1), a vent (14), and a muffler (15), with one end with an exhaust flap (12) of the header pipe being adjusted to Connected to the engine exhaust port And the other end is connected to the aforementioned silencer (15), where such a hole (14) is connected between the one end with the exhaust flap (12) and the extinguisher. Such noise (15) at one point should be between 40% and 60% of the developed header pipe length from the front of the said exhaust flange (12) along the length. Of the said header pipe Exhaust ventilation system for improving the torque characteristics of spark ignition engines. Four-stroke, single-cylinder The exhaust system consists of a header pipe (1), a vent (14), and a muffler (15), with one end with an exhaust flap (12) of the header pipe being adjusted to Connected to the engine exhaust port And the other end is connected to the aforementioned silencer (15), where such a hole (14) is connected between the one end with the exhaust flap (12) and the muffler. (15) as mentioned at one point, which should be between 40% and 60% of the developed header pipe length from the face of such exhaust flap (12) along the length. Of the said header pipe
