January 1 of next year is the deadline for the implementation of the four standards for trucks. At present, there are still five months from this deadline, but most regions have already begun to officially implement the Fourth National. According to the statistics of relevant companies on 260 cities across the country, by the end of July, 210 cities had officially implemented State IV, accounting for 81% of the total survey sample. The reporter recently also visited the truck market in many places and found that the trucks on the market were already four cars, but the four of them used EGR technology.
Country, four light truck on the market are mostly EGR car <br> <br> trucks implementation of the four countries, there are generally two technical routes, one EGR, the other is SCR. Recently, the reporter visited Hebei Tongli Automobile Trade City and Beijing Jingliang Road Truck Market and saw various light trucks with different brands and different wheelbases. After carefully observing the common rail system of the engine and the details of the hoses of the post-processing system, it was found that most of the four technical lines adopted by the light trucks on the market were EGR, and only a few vehicles were SCRs.
The prominent feature of the light truck EGR technology route is the addition of a DOC/POC post-processing device in front of the silencer. Therefore, based on external features and with some expertise, it is easy to identify which vehicle is using EGR and which vehicle is using SCR.
Why light trucks use EGR technology route? Wang Wen, the head of an Ouma 4S shop in Hebei Tongli Automobile Trading City, said that users all like to use EGR's four cars. “We sold 34 vehicles and four cars this year, 33 of which were EGR.†Wang Wenxue said, “The selling of EGR cars is mainly due to the fact that they do not need to add urea, which saves money and saves time, and saves a lot of trouble. child."
The company's production of four light trucks using EGR
Since EGR is adopted in the four light trucks sold on the market, most of the four light trucks produced by the company are of course EGR vehicles. The reporter recently interviewed Jianghuai and Futian. The responsible persons of the two companies confirmed to the reporter that the four light trucks they produced were basically EGR vehicles.
Gu Dehua, business director of Foton Motors Group and Omagh's Business Division, said that all Omar 3 products are equipped with Foton Cummins 2.8L or 3.8L engines, and both EGRPOC and SCR technology routes can be used. The technical route, Omar can easily meet the national four emission standards. However, Gu Dehua said: "The EGRPOC is definitely more. The vehicles that Omar can use on the EGRPOC technology route are about 9 times as many as SCRs. That is, 10 of the 10 Omars can have EGRPOC."
Gu Dehua said that Foton mainly manufactures EGR vehicles, mainly based on the needs of customers. For Foton Ouma, it is easy to adopt which technology route to reach the National IV. However, most users believe that the cost of upgrading E-GRPOC and SCR is almost the same, that is, the cost of a one-time car is almost the same, but the SCR will continue to add urea later, not only the high cost, but also a waste of time and energy, in some urea filling facilities also Incomplete places, and even there is no place to add urea lead to OBD alarms and vehicle failure. "So, users like to buy EGR light trucks, Foton Ouma can also vote for user preferences to meet user needs as the top priority." Gu Dehua said.
Wan Feng, head of the Jianghuai Light Truck Network Management Department, also stated that the state-owned light trucks produced by JAC have adopted the EGR technology route. As for the reason, like Fukuda, it is based on the preferences of customers.
Users prefer EGR cars because of their low cost <br><br> The reporter interviewed several light-card users and asked why they prefer to purchase the NS4 light trucks using EGR technology. Their answer is basically the same, mainly because the EGR light truck does not need to add urea, which saves the use cost. Regardless of EGR or SCR, the upgrade cost is almost the same. Therefore, the overall cost of the EGR car is lower than that of the SCR.
So, what is the urea use cost of the SCR light truck? After investigation, the reporter found that the current domestic market price of urea solution is 70 yuan per barrel, 1 barrel capacity of 10 liters. UCC consumption of light trucks is generally 3%~5% of diesel consumption. Therefore, if a user purchases an SCR vehicle, 100 yuan of urea will be consumed per 1000 kilometers of travel. If the selected urea is of poor quality, it may also cause OBD alarms or even engine failures. Although the current user replenishment of urea does not necessarily have to be filled by a dedicated urea filling facility, but can be purchased in barrels or bags of urea, purchases and refuelings themselves are troublesome, and users are therefore reluctant to purchase SCR light trucks.
A user who bought a light truck at the Jingliang Road truck market in Beijing stated that even if the EGR vehicle is more expensive than the SCR by RMB 1000~2000, he will purchase an EGR vehicle. "Because I'm afraid of trouble, not to mention the price of EGR cars and SCR cars is similar," the user said.
