Problems solved by technology

The temperature of the exhaust gas released when the engine is working is very high, and the heat insulation effect of the existing exhaust pipe is poor, which causes the temperature of the outer surface of the exhaust manifold to be too high, which will cause damage

Abstract

The invention discloses an engine exhaust pipe which comprises an exhaust manifold and a plurality of exhaust branch pipes; the exhaust branch pipes communicate with the exhaust manifold; an outlet pipe is arranged on the exhaust manifold; the air inlet ends of the exhaust branch pipes are connected with first connecting flanges correspondingly; the air outlet end of the outlet pipe is connected with a second connecting flange; connecting holes are formed in the first connecting flanges and the second connecting flange; the outlet pipe and the exhaust branch pipes are tapered pipes; one end, having the small diameter, of each tapered pipe is welded with the exhaust manifold; the outer walls of the tapered pipes are correspondingly sleeved with heat dissipation rings which are tapered rings; and the tapered rings and the tapered pipes have the same taper. The engine exhaust pipe is high in exhaust velocity and good in exhaust effect, and has a better heat dissipation effect, the outer surface temperature of the engine exhaust pipe can be lowered effectively, and normal operation of an engine can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to an engine exhaust pipe. Background technique [0002] After the mixed gas in the engine cylinder is burned, the exhaust gas should be removed, so an exhaust pipe is installed at the exhaust port of the engine cylinder. The exhaust pipe is connected to the engine cylinder block, and the exhaust gas of each cylinder is collected and introduced into the exhaust main pipe, with divergent pipelines. The temperature of the exhaust gas released when the engine is working is very high, and the heat insulation effect of the existing exhaust pipe is poor, which will cause the outer surface temperature of the exhaust manifold to be too high, which will cause damage to the sensors or components around the exhaust pipe, and even ignite The oil pipe may cause oil leakage from the fuel tank, and the exhaust speed of the existing exhaust pipe is slow, which may easily lead to poor exhaust and e...
