Engine exhaust multi-layer heat balance system

Abstract

The invention discloses an engine exhaust multilayer heat balance system. The engine exhaust multilayer heat balance system comprises an exhaust pipe; an exhaust pipe first-layer cooling assembly which comprises an exhaust pipe first-layer wrapping cavity, a first-layer flow valve and a first-layer temperature adjusting valve, wherein the exhaust pipe first-layer wrapping cavity is communicated with a cooling system of an engine; an exhaust pipe second-layer cooling assembly which comprises an exhaust pipe second-layer wrapping cavity, a second-layer flow valve and a second-layer temperature adjusting valve, wherein the exhaust pipe second-layer wrapping cavity is communicated with a lubricating system of the engine; and an exhaust pipe third-layer cooling assembly which comprises an exhaust pipe third-layer wrapping cavity, a third-layer flow valve and a third-layer temperature adjusting valve, wherein the exhaust pipe third-layer wrapping cavity is communicated with a gas taking system of the engine. The engine exhaust multilayer heat balance system can achieve an adjustment of the lubricating system, an air management system, a post-treatment system and the cooling system, and aheat balance of air, engine oil, water and the like can be achieved.

Description

technical field [0001] The invention relates to the field of engines, in particular to an engine exhaust multilayer heat balance system. Background technique [0002] As we all know, when the internal combustion engine is working, the high-temperature and high-pressure exhaust gas needs to be collected through the exhaust pipe and then discharged out of the engine body. For exhaust gas turbocharged models, the exhaust gas discharged through the exhaust pipe also needs to work on the turbine of the turbocharger to drive the compressor. Compressed air to provide a fresh, sufficient charge of intake air to the internal combustion engine. In order to prevent the surface temperature of the exhaust pipe from being too high, which will affect the surrounding parts or objects, the outer surface of the exhaust pipe is usually insulated with wrapping materials and cover plates, or a water-cooled exhaust pipe is used for heat insulation, but it causes engine damage. Waste of exhaust h...
