The car urea machinery equipment.

Jiahe machinery and equipment automotive urea urea equipment for car in terms of the product at the beginning of the current promotion I think more reflected in market development and product after-sales tracking of dealers. First let the dealer and the user accept then help the dealer to sell the product then help the user to solve the problem. Our company car urea production equipment after years of research and development innovation improvement has entered the large-scale promotion and industrial production stage! Ultrapure water for urea equipment adopt pretreatment the penetrating technology mixed bed EDI device as well as the method of level after processing remove the conductive medium is almost entirely in the water and water dissociation of colloidal substance gas and organic matter removal to very low levels of water treatment equipment. Now the five standards of diesel is most used in SCR engine technology the technology need to add the vehicle AdBlue also known as urea solution it is a kind of nitrogen oxides selective catalytic reductant purity is 32.5% of the super car urea synthesized and purified water.

The five cars in the process of driving the proper use of vehicle urea need to pay attention to the following items: check with the amount of urea urea tank should be used according to the schedule to estimate for the amount of urea so as to avoid driving in the process of urea insufficient lead vehicle engine stalled.
1. If the mileage is large you can choose to carry a can of urea in the car for emergency refueling.
2. Add the urea solution and choose the special urea filling pipe to prevent impurities.
3. After adding the urea solution tighten the lid of the urea tank to avoid contaminants in the air and cause the urea to deteriorate or crystallize.
4. Do not turn off the total power supply in the engine for at least 30 seconds. The SCR system will discharge the residual vehicle urea solution in the pipe to avoid the crystallization of the nozzle.
5 urea solution crystallization is a common phenomenon but do not use detergent to clean commercially available cleaning agents will damage the key elements of SCR system catalyst * treatment method is to use hot water to rinse neither damage SCR system and can effectively remove the crystallization.
The consumption of urea is related to fuel consumption and vehicle SCR system which is not related to urea brand. Amount of urea urea feeder out EMC according to the nox sensor by the engine exhaust temperature sensor and the transmission of the urea pressure sensor information control urea pump use urea jet injector into the exhaust pipe mixing with the engine exhaust gas and chemical reaction on the carrier of the muffler so as to purify exhaust gas. Sometimes the EMC and sensors the matching of urea pump nozzle is bad very easy to cause the amount of urea and emissions do not match such not only cause the waste of the urea solution at the same time also can lead to excess ammonia pollution in the air.
Jiahe urea machinery and equipment automotive sensor sensing the temperature of molten urea and urea box level unable to detect urea quality some models of urea tank sensors for the content of urea solution has a certain memory function change different brands of urea solution will send alarm to ECU in case of this kind of situation can contact related to 4 s shop for system upgrade. This alarm does not determine the quality of the urea solution. Each installation of urea spray and DCU is one-to-one never used interchangeably filter need to be cleaned regularly in order to maintain the normal injection pressure filter maintenance cycle is 50000 km or 1000 h in the case of urea solution contaminated the service life of filter will be shortened.
