System introduction of Weichai generator

Weichai generator scr post-treatment system, the exhaust gas emitted by the engine is fully mixed with the ammonia gas generated by the hydrolysis and pyrolysis of urea, and through the catalytic conversion of the scr box at high temperature, the NO gas in the exhaust gas is converted into nitrogen and water to achieve the purpose of reducing pollution.
The function of each component of the scr post-processing system of Weichai generator, the function of the scr box is to fully mix the exhaust gas and ammonia gas, and play the role of catalytic conversion under the high temperature of the exhaust gas. to the effect of noise reduction. The urea tank is a storage container for urea. The function of the Bosch system urea pump is to extract urea and establish high pressure, and transport the high pressure urea through the urea pipe to the urea nozzle. The urea nozzle of the Bosch system is controlled by ecu, and the solenoid valve of the nozzle is opened and closed intermittently. When the nozzle is opened, the high-pressure urea is atomized and sprayed into the scr box. The urea injection amount of the non-air-assisted Bosch urea injection system is controlled by the nozzle, and the urea injection amount of the air-assisted injection system is controlled by the urea pump. The nitrogen and oxygen sensor is responsible for monitoring the no value of the exhaust gas and monitoring whether the emission exceeds the standard. The exhaust temperature sensor is responsible for measuring the exhaust gas temperature at the intake end of the scr box.
