A cavity-splitting exhaust pipe assembly and engine

Abstract

The invention relates to the technical field of engines, and in particular to a split-cavity and split-flow exhaust pipe assembly and an engine. The exhaust pipe assembly is provided with an exhaust gas cavity, an exhaust port communicating with the exhaust gas cavity, and at least two intake air. The exhaust port is located at one end of the exhaust pipe assembly, and also includes a water inlet, a water inlet chamber A, a water inlet chamber B, a water return chamber and a drain that are arranged on the sub-chamber split-flow exhaust pipe assembly. The number of water inlets is the same as the number of air inlets; the water inlet chamber A is connected to a part of the water inlet; the water inlet chamber B is connected to another part of the water inlet; One end of the formed exhaust port is connected; the drain port is located at the other end of the exhaust pipe assembly; the water inlet cavity A and the return water cavity are both communicated with the drain port; the engine includes the above-mentioned sub-chamber and split-flow exhaust pipe assembly. The cavity-split flow exhaust pipe assembly provided by the invention has the functions of realizing cavity division and flow division, so that the design of the exhaust pipe assembly is more compact and beautiful.

Description

technical field [0001] The invention relates to the field of engine manufacturing, in particular to a cavity-splitting exhaust pipe assembly and an engine. Background technique [0002] In some special areas, the various pipes of the engine need to be protected so that their temperature can meet the requirements. For example, if there is no protection for the exhaust pipes used in marine and naval engines, the temperature of the pipes will be very high and people will not be able to approach them. Therefore, in ship regulations, the surface temperature of the pipes needs to be reduced to below 220°C. [0003] In the prior art, the outer surface of the exhaust pipeline is usually wrapped with a thermal insulation material with very poor thermal conductivity, and the exhaust pipeline is separated from the outside world through the thermal insulation material, which indirectly reduces the surface temperature of the pipeline, but the heat insulation The material is prone to cra...
