Abstract

The invention discloses a waste gas recirculating system of an engine. The waste gas recirculating system is characterized by comprising a waste gas turbocharger, an air inflow pipe, an intercooler and a moisture absorber; the waste gas turbocharger comprises a turbine and a gas compressor; a waste gas inlet of the turbine is connected with an exhaust manifold of the engine; after a waste gas outlet of the turbine is connected with the air inflow pipe, the waste gas outlet is connected with a mixed gas inlet of the gas compressor; and after a mixed gas outlet of the gas compressor is sequentially connected with the moisture absorber and the intercooler, the mixed gas outlet is connected with an inflow manifold of the engine. According to the system, the moisture absorber is arranged in a waste gas circulating loop, water vapor is removed from mixed gas, the mixed gas is dehumidified into a dry state, and the problem that water films or liquid drops from water condensation are blown into an air cylinder, so that the engine flames out is solved.

Description

technical field [0001] The present application relates to the technical field of engines, in particular to an exhaust gas recirculation system of an engine. Background technique [0002] The supercharged engine runs at a high speed through the exhaust gas discharged from the engine, which drives the coaxial compressor to rotate at a high speed, and forcibly presses the supercharged air into the cylinder. In order to delay the combustion process and thereby reduce the generation of harmful emissions, it is common practice to introduce part of the exhaust gas produced by the engine back to the intake side to mix with fresh air, that is, Exhaust Gas Recirculation. The temperature of the mixed gas increases after being compressed, which not only affects the charging efficiency, but also tends to cause deflagration, so an intercooler is usually placed after the supercharger for cooling. The well-combusted exhaust gas contains a large amount of water vapor. As the temperature dr...
