“If a worker wants to do something good, he must first sharpen his tools.†This saying is also popular in the truck field. Many users will choose the right transport truck as a top priority when carrying out transportation. The reference standard for buying a car is the engine. At the recent SAIC Cummins Truck Product Recommendation Conference, many users stated that choosing a fuel-efficient engine is the guarantee of making money, and Xi'an Cummins Engine is such an engine that allows users to rest assured.
Xi'an Cummins said that many people are familiar with it, especially for Cummins, who is the “parent†of the United States. The Cummins ISM series 11-liter all-electrically-controlled heavy-duty diesel engine produced in the technology-introduction mode synchronized with the European and American markets has been recognized by users with its high quality, low failure rate, and economical efficiency, especially when the freight rates are rising. The engine's fuel saving is even more valuable. Take the Cummins ISM385 engine as an example to explore Xi'an Cummins Engine Pioneer!
The users familiar with Xi'an Cummins Engine all know that the reason why fuel can be saved lies in Xi'an Cummins's secret weapon - the wit switch!
The controllable fuel economy device developed by Xi'an Cummins for different road conditions, developed by Xi'an Cummins, provides a simple and convenient third gear selection for the driver on the control panel of the cab through close cooperation with the vehicle manufacturer. For different road conditions such as high-speed, plain or hilly terrain, and different loading and unloading conditions such as full load, standard load, and no-load, flexibly select the three gears of the “wise man†switch, Power, Standard, or Economy. Economy ensures that the engine can always operate under optimal fuel conditions.
This new gear system ensures smooth acceleration, intelligently assists the driver in shifting gears at a reasonable speed, and avoids the dangerous behavior of speeding by the maximum speed limit, guiding the driver to develop good driving habits, and making the driving of heavy trucks easy. . When the user is driving, just tap the "witness" intelligent fuel saving switch to realize the dialogue and interaction between the "driver" and the "engine". The "witness" will help the user to master the best fuel consumption regardless of the user's pull. The goods are unloaded, heavy, and standard. Simply press the “wisdom†fuel saving switch to maximize the efficiency of energy use. The experimental results show that the same driver uses the “wisdom†fuel saving switch before and after The difference in fuel consumption is 3% to 7%.
According to a person in charge of a logistics company using the Cummins ISM385 30 engine, the company has purchased a number of Auman trucks equipped with Xi'an Cummins Engine. All of them are equipped with witless switches, and drivers who are not familiar with driving conditions and are not skilled enough to come Saying that a simple gear adjustment can make the engine operate in an optimized state, it is indeed a very intimate service design. Moreover, using the wiskey switch, it ran from Shenzhen to the city of Beijing for 2,200 kilometers. The average fuel consumption per hundred kilometers is 1-2 times lower than that of other countries' products, and a 50-80 oils can be used for a round trip. The operating costs are reflected. . An oil does not seem to have much money, but for the logistics company, it is related to the entire revenue.
In addition to the "witness" switch, Xi'an Cummins has also performed fuel-saving technology upgrades in other areas. According to one of the Cummins ISM385 engines, when he purchased this engine, he learned that the engine's low-speed, high-torque technology can maximize torque. Reach 1825Nm / 1000-1400r/min, rated power speed is 280kW / 1900r/min, can match the rear axle with small speed ratio, ensure that the engine always runs in the economical speed area, strong power and fuel economy; six-cylinder four-valve design, sufficient air intake Exhaust, exhaust, high combustion rate, to ensure that every drop of fuel is effective, of course, can save fuel.
In fact, many detailed designs of Xi'an Cummins can reflect the economics of fuel consumption, including smart fans, that is, the use of electronically controlled fan devices, the fan speed is automatically controlled according to the environment and water temperature, effectively saving the power consumed by the engine, while increasing the thermal efficiency of the engine, In order to achieve the purpose of fuel-efficient; for different torque available application conditions, optimize the combustion system to make it the best economy; reduce frictional power consumption, innovative new piston ring design and new coating technology, piston skirt line design and Coating technology, new design of bearing bushes and new coating technology, through systematic engineering, reduce fuel consumption in all aspects.
At present, Cummins ISM series engines are widely used in road vehicles and mechanical equipment such as trucks, passenger cars, RVs, light commercial vehicles, and pick-up trucks. The Cummins ISM385 30 engine is popular in the truck industry and is used by Auman and Shaanxi Auto truck users. Trust!
