According to the plan of the National Ministry of Ecology and Environment Protection, China plans to gradually implement the Sixth National Emission Standard from July 1, 2020. The upgrade of emission standards will inevitably bring about the upgrading of product structure. In the face of changes in the industry, Dongfeng Cummins has already made solid preparations. It not only strictly complies with China's six emission standards, but also in terms of reliability, economy, and power. Do a full preparation.
Dongfeng Cummins Durability Professional Working Group Build a durable professional group to explore the secrets of a million kilometers of engine
When the implementation of the Sixth National Standards entered a countdown, Dongfeng Cummins launched a key project - the formation of the Dongfeng Cummins Durability Professional Working Group, the task of this "mysterious group" is to find long-range mileage Dongfeng Cummins Engine , study their operational status, and thus establish The critical part durability model reduces the maintenance rate of key parts and provides database support for the research and development of “Six National†engines. With this original intention, the professional work team dismantled the power cylinders, including cylinder blocks, cylinder heads, connecting rods, pistons, piston rings, crankshafts, camshafts and other key components.
Although there are many long-haul milestones of the Dongfeng Cummins engine in operation on the market, it is still a difficult task to remove these “baby†in batches from users. However, relying on Dongfeng Cummins' strong after-sales service network, through continuous communication with major customers, it successfully collected more than one million miles of engines. After conducting a series of performance and emission test studies on these engines, valuable first-hand information was obtained.
Judging from the test of oil consumption, even if these engines have operated over one million kilometers, the consumption of old machines is still far lower than the average fuel consumption of competing products on the market. This shows that after the long-range mileage of the Dongfeng Cummins engine, the performance of the power cylinder is still very eye-catching! The reason is that the Cummins engine in the initial design stage for the long-term consideration of the durability of the engine.

"Endurance Legend" comes from the design concept
The total number of truck engine parts on the general market is more than 1,000, while the number of parts of Dongfeng Cummins Engine is about 20% less than other engines. There are few parts and the connection area is small. The possibility of failure is much less, and the service life of the engine is much less. Get extended.
In addition to extending the traditional advantages of the National V Engine, the project team will also improve the cylinders in the six stages of the country. In addition, the design of the friction reducing function is also added to reduce the internal friction of the engine; the use of thermal management Technology improves thermal efficiency, helps to meet emission standards, and helps improve fuel economy and reduce fuel consumption.
Helps the sequel to the "Dirty Legends" and we have done more
During the product development stage, Dongfeng Cummins has double insurance to ensure the reliability of the engine. The fatigue laboratory will perform independent material performance and fatigue resistance tests on parts to explore the limits of component test performance. After the parts are tested, we will also carry the engine for overall testing to check the stable performance of all parts.
Dongfeng Cummins Engine Parts
In the engine analysis studio, the old machine that has operated the long mileage is stored separately. After the sample reaches a certain number, the research is performed. The use performance limit of each part is observed from numerous samples, and more data are accumulated. Put data into product R&D to promote gradual upgrade of products.

Good maintenance habits are also important factors of "durability legend"
"In addition to the quality of the product itself, what factors have contributed to the performance of the Dongfeng Cummins engine after it has operated for a million kilometers?"
Through dismantling and understanding, these owners have paid great attention to vehicle and engine maintenance, especially regular oil change, oil filter and adjustment of valve clearance.
We all know that inferior oils and filters can cause wear of the engine's lubrication components (cylinder pull, pull, or even engine scrap), and use Dongfeng Cummins pure oil and filters, and perform maintenance according to their required maintenance intervals. It can effectively extend the life of the engine.
The use of inferior oil or poor quality filter products causes severe engine bearing wear
In the process of vehicle operation, due to the accumulation of mileage, there will be a certain amount of wear and looseness between the valve stem and the rocker arm or the transmission part, and the influence of carbon deposition will make the engine factory-set valve. The gap has changed and there have been problems such as weakness, high fuel consumption, and difficulty in starting up. In this case, Dongfeng Cummins suggested that the service station should be used to adjust the valve clearance for every 20,000 kilometers of operation.
As a leading brand in the diesel engine industry, Dongfeng Cummins has fully prepared for the Sixth National Emission Standard. At the same time as the implementation of the Sixth National Emission Standard, Dongfeng Cummins will also bring a strong “strong†national six engine to the Kang Powder, continuing the “durability legend†and helping Kangfen achieve a beautiful life in the United States!
