Fuel economy is the hard truth
The biggest difference between the State III engine and the State II engine is the replacement of the mechanical pump with an electronic fuel injection system, which makes the matching between the fuel supply quantity and the intake air quantity more accurate, and the combustion of the oil product is more complete, thereby achieving the unity of energy saving and emission reduction. . This means that the advanced performance and matching of the EFI system determines the overall performance of the State III engine.
Taking Iveco light passengers using Sophie III engines as an example, since the engine itself is imported from Italy as a whole and the advanced German Bosch high-pressure common-rail system is adopted, the matching is good, so the fuel consumption is 10% lower than that of Sofim II engines. about. The industry figures calculated that the same quality of the diesel vehicle itself is 20% more fuel efficient than the gasoline engine. Iveco's diesel III product is about 10% more fuel efficient than some diesel models. In this case, Iveco III products are used. This is equivalent to saving nearly 30% of fuel consumption costs.
Reliance is the hard truth
At present, there are three kinds of technical means for the implementation of State III in domestic commercial vehicle engines: electronically-controlled high-pressure common-rail engines, electronically-controlled single-unit pump engines, and electronically-controlled EGR engines. Among them, high-pressure common rail fuel injection technology is recognized by the industry as a very mature diesel engine III technology.
At present, the National III engines used by many well-known commercial vehicle companies are basically high-pressure common rail injection systems. As the high-pressure common rail fuel injection technology is a mature technology in Europe, the domestic European joint venture commercial vehicle enterprises have mastered the technology earlier. For example, Nanjing Iveco had already launched the National III products to the Chinese market as early as 2004. After years of road experiment and user's practice, both the oil adaptability and the stability of the vehicle have been fully recognized by the market. Its unique filtration self-detection alarm identification system can also effectively prevent the damage of unqualified oil products to the engine.
It is understood that since Beijing implemented the National III emission standards in 2005, sales of Iveco Lightbus in Beijing have continuously maintained an average increase of 30%.
Service is the last word
It is understood that because some commercial vehicle companies do not possess the core technology of the State III engine, these enterprises have to temporarily upgrade the engine in order to meet the national III emission standards. Lin Wei, Secretary-General of the China Light Vehicle United Analysis Association, told the author that after the full implementation of the National III emission standards, the after-sales service for commercial vehicle companies is also a test, including whether the State III accessories can be put in place in time, whether it is equipped with professional engine diagnostic equipment and Whether the maintenance personnel have mastered the maintenance technology of the National III engine. “The State III engine adopts EFI technology, and the requirements for diagnostic equipment and personnel skills have been improved. Many companies have a very short time to market for the State III engines and it is difficult to diagnose equipment and personnel skills.â€
According to reports, after the listing of the State III products in 2004, Nanjing Iveco equipped the national service system in batches with a professional engine diagnostic computer. "Because Iveco III products are available soon and have a large amount of inventory, our after-sales system has mature service and maintenance experience to ensure that our customers can receive professional services in the first place," said Shuai Guowang, Vice Minister of After-sale Service of Nanjing Iveco.
Three Real Estate Choices for Commercial Vehicles in the State III Era
After a grace period of six months, the emission standards of China Automobile III have been fully implemented since July 1. People's attention has also shifted to focus on who can provide top-notch products of State III. As we all know, the engine is the decisive element of the vehicle emission level and vehicle performance. The economic, reliability, and maintenance services of the State III commercial vehicle are the three hardest reasons for them to choose the State III commercial vehicle.
