How far can China National Heavy Duty Truck "EGR Road" go?

Since July 1, last year, it has been one year since the full implementation of the National III emission standards. The most popular is the heavy-duty field. The disputes between the EGR and high-pressure common-rail technologies have been at the top of the turmoil. With a certain relative price advantage, China National Heavy Duty Truck EGR has achieved a good market performance, but the view of whether EGR technology is suitable for national conditions is also very embarrassing.

China National Heavy Duty Truck EGR or will encounter quality doors again

Mr. Wang, who lives in Xuanhua, Hebei Province, is a truck driver. After several years of hard work, Mr. Wang took all his savings and borrowed some money from relatives and friends. In March of this year, he bought a China Heavy Duty Truck EGR HOWO heavy truck. However, according to Mr. Wang's words, I don't know what EGR is. At the time, it was cheaper to buy it. But who knows that the engine is always in trouble, leaking water, burning oil, and boiling the pot from time to time. The car failed on the road. Together with fuel consumption, it does not make any money at all. Buy this car and give it to you .

Such problems as Mr. Wang encountered are not accidental. In fact, after China launched EGR heavy truck models, there have been a lot of user feedback that quality problems, last year December 13, Yulin a user's 18 China National Heavy Duty Truck HOWO heavy trucks lined up in a long queue lines, heavy complaints China steam, the complaints directed at product quality and other issues, in which the fuel consumption and the failure rate of the most prominent issues.

There are inherent technical defects in EGR

In simple terms, the principle of the EGR engine is to introduce a small part of the exhaust gas into the cylinder for secondary combustion to achieve emission reduction. Since only a simple adjustment of the State II engine is required, the cost is relatively low. However, the EGR valve is prone to be leaked by corrosion under high temperature exhaust conditions for a long period of time . It also causes the phenomenon of black smoke. It is difficult for vehicles to meet emission standards after a period of operation. This is the reason why CNG EGR is denounced as a major cause of the country ⅲ false. The CCTV Smoky Gate incident reported by CCTV’s “Today’s Statement” last year also reflected some problems. This is not a concept at all with high pressure common rail technology that can precisely control the fuel system . From the actual operating conditions, it can also be seen that EGR engines are at a disadvantage in terms of combustion efficiency, fuel economy, and unit power.

China National Heavy Duty Truck enters dilemma

Some analysts said that when China National Heavy Duty Truck Corporation chose the high-pressure common rail line in other domestic manufacturers, the introduction of EGR was more like a gamble. Frequent quality problems reflects the fact that China's heavy truck as a domestic heavy commercial vehicles is an important force in the engine's technical strength is weak, there is also a lack of integration of industrial chain advantage.

Perhaps China National Heavy Duty Truck is using EGR products as a transitional product. It is said that along with the approach of China IV and China V, China National Heavy Duty Truck is gradually moving closer to the common rail of high pressure , but this is not a tortoise-runner race. Enterprises that run ahead will not stop and wait. From a realistic point of view, for China National Heavy Duty Truck, it is insisted that EGR is still the starting point to follow the high pressure common rail is not a choice that can make the company secure. Before the third option is found, China National Heavy Duty Truck may be uneasy.
