The six-cylinder machine has a large horsepower and a large torque, and can be equipped with a rear axle with a small speed ratio. It can achieve a higher speed at low engine speeds. At the same time, the power reserve of the six-cylinder is larger, and there is no need to frequently shift gears in the mountains and hills. So the six-cylinder machine does not cost more than the four-cylinder machine. † Dual Spout,Brass Dual Spout,Stainless Steel Dual Spout,Two-Way Jet Nozzle KAIPING LIPU SANITARY WARE CO.LTD , https://www.ebt-pro.com
"The high-speed overloading of a four-cylinder engine inevitably results in damage to the engine. Over time, the engine is no longer powered, resulting in more fuel consumption and higher failure rate due to overload."
"My point is that the current purchase of horsepower must not be the same as before. The point of view is that the engines used by the HPP are basically high horsepower, low speed, high torque and not necessarily lower than the horsepower." 
Recently, the “Best Configuration for 6.8m Vans in Your Mind - Liuqi invites you to select PK models together†organized by Dongfeng Liuzhou Automobile Co., Ltd. has announced the end of the prize survey activity, which has attracted more than 1,200 registered forum users. And give their own answers, the final 326 lucky participants come out and get the mobile phone charging treasure, commemorative T-shirt and other prizes provided by Dongfeng Liuzhou.
According to the organizer of an activity Dongfeng Liuzhou Automobile, an activity official said that in addition to popularizing some of the common sense of the “four-cylinder machine†and “six-cylinder machine†in the middle of the card, it is also to better coordinate with Liuqi’s latest ride. Long M3 "super value" in the truck-type listing, while the activities for the majority of drivers, card friends and other industry insiders openly solicited "the best configuration of 6.8-meter trucks," is more fully reflects the Liuzhou always attaches importance to the user experience to The actual needs of the market and users as the starting point of the concept of repair!
It is understood that this time listed by the dragon M3 "Value Edition" in the card, but Liu Auto in 2009 after the third generation of Long series of classic products - after the new dragon 609 masterpiece, from R & D to production down the assembly line lasted 5 years old. In the previous phase of market research and analysis, Liuzhou Automobile's technicians integrated the customer's load, road conditions, and actual operational needs, and combined well-known engine manufacturer Dongfeng Cummins with the introduction of IQA-specific test technology for the entire vehicle, including engine intake, exhaust, and cooling. Effective pre-test work such as bench test verification and road profile acquisition of typical road conditions strives to maximize the effective integration of technology research and development with actual needs.
It is also based on a series of results of the pre-research and development work, so that Liu Automobile has a clearer direction in the new car vehicle configuration, especially the key core components - powertrain collocation. After several comparisons, Liuzhou engineers finally determined Cummins ISB17040 six-cylinder 170-horsepower engine for the Long M3 "super value" version, matching Fast 8-speed gearbox (the most high-end is overdrive), 8T rear axle, and according to operating conditions There are 5.286, 4.875 and 5.833 speed ratio options.
In fact, most of the truck driver’s friends in the survey stated that the main factors that dictate whether they choose a four-cylinder or six-cylinder machine are still fuel consumption, power and price. The advent of the Dragon M3 “Super Value Edition†undoubtedly solved these problems to some extent. From a fuel-saving perspective, Concord has always been well-known for its high-efficiency and fuel-efficient advantages; a relatively high 170 horsepower can also compensate for the shortcomings of insufficient power under special conditions such as mountainous terrain, hills, and country roads, especially under heavy load conditions. The advantages of low fuel consumption and strong power are even more obvious. As for the price factor, the person in charge of Liuzhou Automobile stated that the other meaning of Liuzhou Automobile's new car “value†is that it is more favorable in terms of price.
In addition to the core with a reasonable powertrain, the Dragon M3 “Super Value Edition†inherits the high demands of Dongfeng Liuzhou in terms of safety, reliability, light weight, and comfort. It is understood that Long M3 Value Edition standard Liuzhou M31A "keel frame structure" cab, door and door frame using integral stamping molding, door double high-strength steel anti-collision beam, the front glass with laminated glass, Leading the industry in safety; the cab industry is the first to launch a full-floating suspension, four-point spring damping, and equipped with M7 imitation leather fabric seats to make driving more comfortable. In addition, the weight of the new car chassis is only 4.78T. The double-layer girder is stamped from Asia's largest and China's only 6300T press once. It is sturdy and durable. With the light weight design of aluminum alloy fuel tanks and other small details, the overall weight of the vehicle is more similar. Products have more advantages.
After the completion of the assembly of the vehicle, in order to further test the performance of the vehicle, Liu Auto also conducted a stringent and comprehensive road test on the new model. After performance tests on various road conditions such as cement roads, sampan plates, and mountain roads in the early stage, the vehicle performance is stable and reliable. At the same time, combined with the market test sales situation, Liu steam has further optimized the Long M3 “Super Value Editionâ€, such as optional disc brakes, front axle with automatic adjustment arm, rear axle lift braking performance, etc. The new model configuration, performance and other more perfect.
