There are many misunderstandings in the process of using the national four-wheel vehicle. Some drivers will remove the vehicle urea alarm equipment OBD, or change the CPU data to avoid adding urea or false environmental protection data to the vehicle. Is this correct? What is the harm? The relevant technical experts explained to us that by defrauding the OBD monitoring, the vehicle's use of urea in the SCR system was depleted by power, which in the first place seemed to reduce a lot of trouble, but the National IV engine was biased towards reducing PM emissions. Combustion, so that emissions of NOx emissions will not only reduce but also increase, exhaust pollution even exceeds the National III vehicles. At the same time, the SCR system will not work for a long time will lead to crystallization of residual urea solution in the SCR system plugging the pipe and nozzle, and because of the long-term lack of liquid soaking so that the life of the SCR system components reduce or even damage, the catalyst loses its catalytic effect, replace the SCR The cost of system components is much higher than the cost of normal use of vehicle urea, which in turn increases the cost of the owner.
