With the arrival of the National II model on July 1, 2009, the disputes of the State III technology genre gradually reached the top. Their technology, originating from overseas growth in China and ultimately self-reliance on their own, or indigenous and self-contained, all of these schools claim to be able to reach State III. Faced with such a complicated situation, those who are involved in rivers and lakes will inevitably be confused and disorderly.
Who can "proudly pride" the country III rivers and lakes? Xiaobian ventured to play "One hundred Xiao-sheng" to try one or two.
State III Dispute High Pressure Common Rail is the Mainstream
At present, the technical solutions of the National II Upgrade Country III are mostly from the aspects of improving fuel injection technology and increasing oil pressure. This is similar to the relationship between internal forces and moves in martial arts.
Electronically controlled injector technology: This technology integrates the fuel injection pump and the nozzle, and the fuel injection pressure is very high, forming an excellent mixture, ensuring good atomization of the fuel, and precise control of the injection start point and fuel injection amount, thereby increasing Diesel engine power, fuel economy, emissions reduction and improved NVH characteristics. However, due to the fact that the fuel injection pressure cannot be kept constant, the emission performance is not very stable. At present, this technology is used less in light commercial vehicles.
The electronically controlled injector technology solves the problem of fuel injection. However, it has some drawbacks in the formation of hydraulic pressure. This makes people think of a critical science in the rivers and lakes – the segment's six-strand excalibur sword. The martial arts requirements of users are very high. They are as helpful as they are when they are good, and bad when they are not good.
In-line pump + EGR technology: This technology uses a simple electronically-controlled mechanical pump plus an EGR exhaust gas reprocessing system to reduce exhaust emissions and eventually achieve the national III emission standard. However, the fuel consumption of the technology will continue to increase during use, and the exhaust gas and particles will significantly affect the performance of the engine. Especially when the engine is idle, low speed, low load, and cold engine, the volume of carbon in the cylinder will be too high and the fuel consumption will be too high. Increase the chance of damage by 15%-30%. Therefore, this technology is extremely contentious in the industry.
“Injury is seven points, injury has been three points,†and the power of the Seven-Handed Injured Boxing is striking. However, as the number of uses increases, the damage to the user itself will increase, and people have to re-examine this item. Martial arts. The simple electronically controlled mechanical pump +EG technology is similar to the Seven Injuries Boxing, so this technology can be included in the school.
High-pressure common rail technology: The common understanding is to install a computer to the engine, let the computer direct the engine to scientifically control the formation of oil pressure and fuel injection; during the entire process, the formation of oil pressure is completely separated from the fuel injection, and the oil pressure is not related to engine speed. . In this way, the best combustion ratio, atomization and optimal ignition time of the diesel engine can be ensured to achieve the purpose of fuel saving and emission reduction. Therefore, the high-pressure common rail is considered by the industry to be the best technical solution for achieving State III.
The Wudang Taijiquan and Tai Chi swords are the two martial arts that the Jianghu people dreamed of, and as long as the practitioners are at ease in the early stages, they will surely make achievements in the future. No one can make this skill out of the right, so high pressure common rail technology can also be called the Wudang faction of the State III technology.
"Authentic" rivers and lakes Jiangling Collection pointing country
As the Wudang faction of the State III technical school, high-pressure common rail technology has a great martial arts appeal. Therefore, people who admire and study the martial arts in the rivers and lakes are more like rivers. In the same division, there are disciples with high talents in martial arts and disciples with low martial arts talents. There are very few who can pass on the essence.
Taking pickup as an example, among the several pickup brands currently using high-pressure common-rail diesel power, Jiangling Collection's power derives from the pure Isuzu 4JB1 technology, just like Zhang Jinwu's Zhang Wuji, a martial-arts family, and a gifted person. Together with his own hard work, he will eventually be able to promote his own profession. Some brands, due to their inherent deficiencies, have introduced high-pressure common rail technology on the basis of imitating 4JB1 technology or other technologies. Although they are able to reach the target country III at one time, their unstable foundation will surely cause serious problems. The final outcome will be the Song Qingshu under Wudang Gate. No difference.
Jiangling Collection, which is famous for its reputation, has always adhered to the path of “Chinese brand, international qualityâ€. At the beginning of 2007, the National III Collectible Pickup Truck with 4JB1-TDCi engine was launched, becoming the first pickup brand to achieve the National III emission standard. In addition to the Euro II turbo diesel engine, the National III Collection has imported the electronically controlled high pressure common rail fuel injection system from Germany's Bosch. The combustion noise is greatly improved and the mechanical noise is further reduced. The engine is in emission, vibration and noise. To a perfect degree, it became the benchmark model of the National III diesel pickup.
Taking a panoramic view of the Pika River, the Jiangling Collection, with its advanced technology and reliable quality, has already possessed the strength of the king regardless of its R&D and production, and has become a pickup hero of the “Proudty†III market.
