Abstract

A water-cooling exhaust pipe for a natural gas engine not for a vehicle is used for a natural gas engine. A supercharger installation face is provided with an exhaust hole and water outlet holes. The exhaust hole communicates with a gas chamber in a water-cooling exhaust pipe, the gas chamber communicates with gas inlet holes of the water-cooling exhaust pipe, and the gas inlet holes communicate with an engine cylinder cover exhaust hole. The water outlet holes communicate with a water jacket in the water-cooling exhaust pipe, the water jacket communicates with a water inlet hole of the water-cooling exhaust pipe, and the water inlet hole communicates with an engine cylinder cover water outlet hole. According to the water-cooling exhaust pipe, by means of circular cooling of cooling water, the temperature of an exhaust manifold body can be reduced to 200 DEG C or lower from 650 DEG C, the temperature of the exhaust manifold body and the temperature and the pressure of exhausted waste gas are obviously reduced, and the service life of the engine is prolonged.

Description

technical field [0001] The invention relates to the technical field of natural gas engines, in particular to a water-cooled exhaust pipe for non-vehicle natural gas engines. Background technique [0002] At present, existing natural gas engines are not equipped with water-cooled exhaust pipes. Since the temperature of natural gas in the combustion chamber of natural gas engines is higher than that of diesel engines and gasoline engines, the exhaust gas temperature is relatively high. When the engine is running at high speed, the volume of the exhaust gas is larger, and the exhaust resistance will also increase, resulting in a decrease in output power; and the engine temperature is too high, which also affects the service life of the engine. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the object of the invention is to provide a water-cooled exhaust pipe for a non-vehicle natural gas engine to prolong the service life of the eng...
