Currently, the heavy truck implementation country's four emission standards adopt SCR technology. In the implementation of the national quadruple trucks, vehicle urea is inseparable from the implementation. Many truck drivers think that the use of national four-vehicle vehicles to add vehicle urea will increase fuel consumption. Is this true? In addition, it was also suggested that the use of national vehicle fuel consumption is reduced, which is why?
The responsible person for vehicle urea production company Meifeng Jialan pointed out that the use of vehicle urea is not directly related to fuel consumption. Vehicle urea is used in the SCR system of the National IV vehicle. The SCR system is linked to the engine through the ECU of the OBD system. If the SCR system does not work properly, the OBD system will reduce the power output of the engine and increase fuel consumption. However, if the SCR system works normally, the National IV engine adopting the high-pressure common rail technology will burn more fully and the car output power will be more stable, which can save about 6% fuel consumption compared with the National III engine, so the vehicle urea will not increase or decrease the engine's Fuel consumption, but high-quality car urea can ensure the normal operation of the SCR system and play a role in helping to reduce fuel consumption.
