TH50221B - Small vehicle engine exhaust purification kit - Google Patents

Abstract

DC60 in the exhaust purification kit for the engine of small vehicles where the exhaust Is provided in the lower surface of the cylinder head which is mounted onto the engine which is assembled Up as part of the power pack Will cause the muffler where the source end has been connected to The exhaust channel extends downward to the rear from the cylinder head. And hoses for import The secondary air is connected to the exhaust port through a metal connecting pipe. This avoids the emergence of problems associated with the arrangement of long, slender pipes. And prevents the air filter from sucking into the heated air, even when the filter Positioned above the power unit, the U-shaped 62a, roughly bent in a U-shaped structure, is formed. In the section of the connecting pipe 62, which makes contact with the exhaust port and connects to the cylinder head 33, the U-shaped section 62a is arranged between the bottom surface of the cylinder head 33 and the exhaust pipe 50 as seen in the side view. Inside the exhaust purification kit for the engine of small vehicles where the exhaust Is provided in the lower surface of the cylinder head which is mounted onto the engine which is assembled Up as part of the power pack Will cause the muffler where the source end has been connected to The exhaust channel extends downward to the rear from the cylinder head.
