In order to meet the requirements of the National IV emission regulations, medium-heavy trucks generally adopt the SCR post-treatment route and use urea to reduce the exhaust gas. The traditional urea injection device uses a urea pump for pressure injection of urea. However, the domestic post-processing technology has always been in the hands of foreign manufacturers. As a result, some user countries' post-processing systems have become more difficult to handle, which may easily lead to difficult maintenance. In order to break the foreign monopoly and master the core technology for the benefit of domestic truck users, FAW has successfully developed a gas flooding urea injection system to fill the technological gap in this field. This technology has independent intellectual property rights and once again led the technological upgrading of the domestic truck market. The following Xiao Bian gave you a brief introduction to the four tools of this truck market: The system is mainly composed of intake and exhaust valves, urea tank modules, urea nozzle modules and corresponding piping. The opening and closing of the intake valve will stabilize the system pressure within a certain range; the vehicle exhausts after flameout. First, the autonomous gas drive urea injection system equipped with the liberation V card has the following advantages: 1, simple structure, long life, good daily maintenance The system is highly integrated, the structure is simple, the failure rate is low, and the spare parts are cheap; only 50,000 km are required to replace the urea filter in the tank, 100,000 km are replaced with gas filters, and the service life reaches more than 1 million kilometers, which reduces user maintenance costs . 2, no longer need to go to the service station to replace the urea pump Gas-flooded urea system provides injection pressure from compressed air and eliminates urea pumps. Users and friends no longer have to worry about replacing the maintenance urea pump at the service station. 3, no longer worry about urea nozzle will burn out Through the well-built technology, Liberation V card + autonomous gas drive = easy and worry-free after the fourth national post-processing, once again let the liberation V card on the forefront of the country's four truck market.
