Description
Technical Field
The invention relates to the technical field of engines, in particular to an exhaust gas recirculation system device of a gasoline supercharged engine.
Background
The Exhaust Gas Recirculation (EGR) technology of an engine is a technology of reintroducing part of exhaust gas on the exhaust side of the engine to the intake side to mix with fresh air and participate in combustion, and mixes cooled exhaust gas with fresh air to reduce the oxygen content in the mixed gas and lower the combustion temperature of a combustion chamber, thereby suppressing the generation of NOx.
For a gasoline engine, when the engine load is small, the throttle opening degree is small, and the pumping loss is large at this time. The external EGR technology is adopted at the time of low load, and in order to keep enough fresh air intake, the opening degree of a throttle valve is required to be increased, so that the pumping loss is reduced, and the fuel economy is improved. In addition, the EGR technology enables the waste gas to be rich in inert gas with higher specific heat capacity, improves the adiabatic index of the mixed gas, effectively reduces the highest combustion temperature, slows down the combustion speed, prolongs the combustion duration and effectively inhibits the occurrence of detonation.
For example, chinese patent CN106762238A discloses a low-pressure exhaust gas recirculation system based on a supercharged engine, which sets the gas-taking position of EGR behind the turbine and the catalyst of the supercharged system, so that the pressure of exhaust gas becomes small, and the working condition range of the EGR system can be operated becomes small; and waste gas is cooled by the EGR cooler and then passes through the EGR valve, so that the pipe pass of the waste gas in front of the EGR valve is longer, the response time of the adjustment of the EGR valve is prolonged, and the waste gas circulation amount is not easy to control accurately.
Chinese patent CN108730073A discloses a high pressure exhaust gas recirculation system of supercharged diesel engine, which sets the gas taking position of EGR before the turbine, but the setting of EGR valve after the EGR cooler still causes long adjustment response time of EGR valve, low control accuracy, and because the EGR system is not provided with a catalyst, the residual gasoline vapor in the exhaust gas is easy to block the EGR valve after cooling; chinese patent CN203717168U discloses an engine and its exhaust gas recirculation system and exhaust manifold. The system arranges an EGR gas taking position in front of a turbine and an EGR valve in front of an EGR cooler, but the structural reliability of the EGR valve is easily influenced because the temperature of exhaust gas discharged by an exhaust manifold is generally as high as 800-900 ℃. In addition, the expansion joints arranged at the two ends of the EGR cooler greatly reduce the pressure of exhaust gas, so that the pressure of the exhaust gas of EGR at the air inlet side is smaller than the pressure of fresh air passing through the compressor, and backflow is easily formed.
Under the development trend of engine integration, miniaturization and more strict emission standard, how can further realize the miniaturization of EGR device under the reliability condition of guaranteeing EGR operation to improve the operating mode scope and the EGR rate of EGR operation becomes the key problem that awaits solution urgently.
