Inlet chamber or gaseous mixture are directly entered cylinder, into cylinder mixed combustion after waste gas discharged by exhaust manifold, portion
Continue cooling recycling by three-way pipe.
Inventor shows that oxygen content is extremely low in EGR gases does not have even, this gas and inlet air by result of the test
After mixing oxygen concentration in cylinder intake can reduce, the oxygen content lower than air (highest) temperature in burning can reduce,
Nitrogen oxides (NO can be suppressedX) generation.Only the EGR under Part load is just operated engine.For example, idling and underload
When, NOXConcentration of emission is low, and in order to ensure that stabilization is burnt, EGR is without work.When gas temperature is low in engine cylinder, NOXDischarge
Concentration is relatively low, and in order to ensure normal combustion, EGR is also without work during cold.Engine only just enters in its hot lower EGR
Row work.In summary, gas in the jar temperature has a great impact to EGR, passes through the temperature sensor inside water cooling charge air cooler
Real-time temperature can be accurately obtained, the cooling capacity of water cooling charge air cooler can be judged by the numerical value of real-time temperature, therefore, the present invention
The simple device of the structure of the present invention is devised on this basis, for further cooling down EGR gases.
Compared to more traditional cooling system for recycled exhaust gas, the present invention can be cooled down to a greater degree to EGR gases so that control
Temperature is more accurate, the higher EGR gases of temperature is imported into three-way pipe, the opening and closing degree of control valve is sent into EGR gases
The water cooling charge air cooler being integrated in inlet manifold is cooled down, and is passed using the temperature installed at inlet manifold's internal water cooling charge air cooler
Sensor detects the temperature of EGR gases, and the fresh air for entering the not high EGR gas mixings of temperature again by three-way pipe is straight
Pick into cylinder, and three-way pipe directly can be assembled in inlet manifold and exhaust manifold by flange and its supporting seal
On.This invention part is few, simple in construction, and Fast Installation can be achieved, and realizes and cools down EGR gases to some extent, increases engine
It air inflow, can not only increase power, and oil consumption can be reduced.
