The implementation of the National IV standard has been a month now. Local trucks in various places in different regions may still be allowed to enter the home, and some can use the national three-car set of four cards, while some strict households need to use the real four. Car. True country is divided into two kinds : SCR and EGR . The advantage of SCR system is that it does not need to change the body. That is to say, State III electronically controlled bare metal plus SCR can realize State IV ; the durability of the engine is good; the fuel economy is good; the fuel and Low oil quality requirements; no catalyst blockage risk; improved technical continuity after State IV ; low maintenance costs. The disadvantage is that the initial cost is high; the quality is relatively large; the effective loss of bicycle is about 400kg ; the requirement for packaging is high; in the case of low-temperature failure, urea solidifies at -11 °C , and is used in the area north of the Yellow River, and a thawing device needs to be installed. Increased costs and loss of payload; The main problem is that urea carried by trucks can only be used at a time between 5,000 and 10,000 km (heavy trucks) at a time. It needs to be replenished in time and is facing urea supply and distribution problems.
Today we will explain to you how to add urea under the SCR system. The price of a barrel of 70 liters of urea solution generally ranges from tens to hundreds of dollars. Urea will be no alarm, if you continue to drive, do not add urea will take the white smoke, the engine detects your exhaust is not up to standard, will limit the twist, is not enough force, and then will further lock the engine, there will be damage to the engine .
The consumption of urea is relatively low. The consumption that meets the Euro IV standard is about 3.5% of the fuel consumption , and meeting the Euro V standard is about 5% of the fuel consumption . When there is no urea in the urea tank, the emission of the engine will not reach the standard, and the vehicle's automatic diagnosis system will also warn the driver to promptly add it.
