At the Shanghai International Auto Show opened on April 22, 2009, various commercial vehicle companies took the outdoor exhibition area of ​​the Shanghai New International Pavilion as their own stage. They showed these “big heads†to the audience and their “prestige†was unmanned. Can. Perhaps inadvertently, it may ignore some of the parts and components that are displayed with the vehicle. At the corner of Shaanxi Heavy-duty Auto Show, Xi'an Cummins, a major engine manufacturer in China's commercial vehicle market, has highlighted its ISM 11-liter four-engine. His weight of 940 kilograms still looked a little "struck alone" at the huge booth. However, when reporters visited a number of OEMs, they discovered that the Xikang ISM 11-liter engine was not alone on the show floor. Many OEMs brought the Xikang machine to Shanghai. Such as Shaanxi Automobile Cummins Twin Crown Four-Emissions Tractor, Valin New Generation Star Kama Concrete Mixer, Foton Euro V12 Bus and so on. Looking at the completely different applications of these three cars, they all chose the same displacement engine. What makes the ISM 11-liter engine "play" so many roles?
The Xikang ISM series 11-liter diesel engine was introduced into the domestic market in the mid-1990s and is one of Cummins' flagship engines. Domestically produced products were formally put on the market in Xi'an on August 8, 2007. The targets were mainly in the mid-to-high end heavy-duty engine sector, and the power range covered 335-440 horsepower. The current global holdings exceed 400,000. On the day of the opening ceremony of Xi'an Cummins, Shanxi Tongtai Automobile Sales & Service Co., Ltd. signed a sales contract for 200 engines with Xi'an Cummins, which shows its influence in the industry.
Through the reporter's understanding, some of Cummins’s powertrain matching systems can relatively accurately specify different engine operating modes based on differences in engines, transmissions, axles and road conditions. It is also possible that the Xikang ISM 11-liter engine can work according to different tasks. In addition, the ability to adapt to different performance adjustments enabled him to create a multi-angled function.
Tractor - Powerful Dora Run Economic Savings
In the field of tractors for road applications, the engines are required to have strong dynamics, superior bearing capacity, and safety and reliability. The ISM11 engine matching the Shaanxi Kings Cummins double crown tractors at the Shanghai International Auto Show is based on these characteristics of modern logistics and transportation performance optimization, ISM11 engine with its powerful power, powerful intelligent electronic control management Features, excellent reliability, high-performance engine braking and excellent environmental protection performance are a good interpretation of the "double crown" of Shaanxi Steam Cummins, which is hailed by the market as the "champion champion + saving champion."
The ISM11 engine is highly integrated with five key systems of Cummins fuel injection, air intake, electric control, combustion optimization, filtration and post-processing, all with complete intellectual property rights, making this engine far superior to similar products in terms of system compatibility and performance. The compression-release engine brake system overturns the traditional concept of engine exhaust brakes — transforming the engine into a power-absorbing air compressor with a maximum braking power of 326 hp; and the ISM11 engine's torque ratio at equivalent horsepower 15-25% higher than other similar products, with features such as heavy starting capacity, large climbing capacity, superior bearing capacity, multi-tapping run, and high transportation efficiency; while comprehensively improved combustion system and INTERACT system precision injection control, Each ignition oil exerts its maximum energy and brings you maximum benefit.
Engineering vehicle - low speed, high torque, high efficiency braking, safe and reliable
At the booth of Valin, the Xingkaima Cement Mixer, which was launched at the Shanghai BMW Exhibition last year, matches the Xikang ISM 11-liter engine. In an exchange with the staff of Valin, we learned that according to the applicable working conditions of cement mixers, low-speed, high-torque engines can support the vitality of this product. It is reported that in the 11-litre displacement section, under the same horsepower, Xi'an Cummins ISM11 engine torque is 15-25% higher than similar products, which undoubtedly makes it a winner in the field of engineering vehicles.
Since the hydraulic motor that rotates the tank driven by the cement mixer takes power from the engine, once the engine fails, the tank stops rotating for more than 2 hours, and the entire tank will be scrapped, causing losses of up to 100,000 yuan. It can be seen that high-reliability engines have also become a must for cement trucks. The Xikang ISM 11-liter engine has been verified by the operation of global customers. The overhaul mileage exceeds 1 million kilometers, and its quality and reliability are well-known in the industry.
Another important target market for Star Kemah is the international market. Cummins' global service network will accelerate the progress of Xingjima's expansion of the international market, while ISM11's global inventory of more than 400,000 units and its good user reputation are used by Star Kemah. One of the main reasons why it is the main driving force.
Intercity bus - Accelerating high and low noise levels
In the field of passenger cars, there have been some changes to the engine requirements. Futian Euro V12m passenger car at the auto show is also equipped with Xikang ISM 11L engine.
Since the passenger car does not need to be overloaded, the maximum output torque of the engine is not high, but the acceleration requirements are relatively harsh. This is not a problem for the Xi'an Cummins ISM11 engine. Xikang ISM11's starting torque is high 1100Nm/600r/min, acceleration performance is more than 20% higher than similar products, which is unmatched by other products, and highly integrated powerful electronic control functions can be optimized according to the user's vehicle design requirements The engine parameters enable the engine to output a relatively constant torque in a certain speed range, and achieve a low-torque high-speed flat road travel function to meet the requirements of the passenger car's special working conditions. It is reported that this seemingly simple requirement cannot be achieved by all engine manufacturers. The high reliability of Xi'an Cummins ISM11 is well-recognized among users. The globally uniform process quality standards and overhauled mileage of over one million kilometers allow car owners and drivers to sit back and relax.
The “New Realm†is one of the themes of the Shanghai International Auto Show. It shows people the future demand for environmentally friendly products. As a commercial vehicle engine, diesel engines will continue to support the development of the industry for a long time to come. Therefore, higher emission standards and more green and environmentally friendly products will become mainstream. While the major engine plants are still conducting repeated laboratory verifications of the National IV products, Xi'an Cummins adhered to the corporate philosophy of “environmental protection and building a better life†and has taken the lead in developing a more energy-efficient and environmentally friendly Euro IV/IV engine. Completion of the vehicle development with a number of host plants, the mature and has passed the European certification of the EU IV / IV products installed in a number of host plants on the vehicle, and has reached mass production capacity. It is reported that on the eve of the auto show, dozens of Shaanqi heavy trucks that matched the Xi'an Cummins ISM11 Euro IV/National IV engine have been put into the market. Perhaps in the not too distant time, we will see more and more commercial vehicles that match the ISM11 State IV green and environmentally friendly engines galloping in the north and south of the river.
