The exhaust gas recirculation device (EGR) is a device that can reduce emissions. ,deutz BFM1013 Water pump will be a part of the engine exhaust gas is introduced into the cylinder, the use of engine exhaust with low oxygen content ,deutz BFM1013 Water pump the characteristics of high heat capacity, reduce the oxygen in the cylinder ,deutz BFM1013 Water pump the maximum combustion temperature, thereby reducing nox generation.The oxygen content in the engine exhaust is low, ,deutz BFM1013 Water pump ,deutz BFM1013 Water pump has a large thermal capacity, which reduces the intake volume after entering into the intake system, which is to reduce the total amount of oxygen. At the same time, the air intake is diluted, the energy of the mixture is reduced, ,deutz BFM1013 Water pump the relative content of the highest combustion temperature ,deutz BFM1013 Water pump oxygen can be reduced, so as to reduce the production of nitrogen oxides effectively.
