Urea water solution for vehicle is a transparent liquid. What aspects do we need to pay attention to when adding urea water for vehicle?
Urea water solution is also known as diesel exhaust treatment liquid, domestic commonly known as: automobile urea, automobile urea, automobile environmental protection urea, vehicle denitrification agent, and called the more common is vehicle urea. There is a separate container on the truck to store the urea solution, and water and diesel can not be added to the urea solution during use. When the engine starts working, ECU accurately measures the injection amount of urea solution according to the diesel engine operating condition, catalytic converter temperature and environmental state. Urea water solution is sprayed into the exhaust pipe, mixed evenly with diesel exhaust and chemically reacted.
At present, the main route for upgrading country 5 of heavy-duty diesel engine in our country is SCR route, using the selective catalytic reduction technique. Its operation process is roughly the exhaust gas from the turbine into the exhaust pipe, exhaust pipe installed with urea metering injection device, spray into urea aqueous solution, urea solution and nitrogen and oxygen compounds in the tail gas in the SCR reaction tank REDOX reaction, generating nitrogen and water exhaust. The urea dose in the SCR system is controlled by the engine management system, and the amount of urea injected needs to match the concentration of NOx.
The cost of urea solution for vehicle use is also a problem we pay more attention to. When it comes to the use cost, it is mainly composed of two aspects, one is the purchase cost of the five models itself, the other is the use cost of urea for vehicles. At first glance, the use of Kokoshikoko products can impose huge costs on truck drivers, but is this really the case? In fact, the use of four countries five products, the cost of the user to buy a car increases by 20,000 to 30,000 yuan, urea use for fuel consumption of 4% to 6%, the use of urea for four cars will also bring an increase in cost. But the fuel economy is 3 to 5 percent less than the original engine. Savings in fuel costs offset these costs.
For the use of urea water solution for vehicles, we need to pay attention to the way of filling. The development direction of urea water solution filling is to set up a urea filling gun at the gas station, which can ensure the purity of urea for vehicles and is not polluted by the filling environment. Another filling channel is bucket filling, which can be filled through the diversion pipe distributed with the box, simple and convenient.
