What is the concept of a million kilometers without overhaul? Learn about

When I heard someone proudly say that the engine of my car was not overhauled for millions of kilometers. I believe many people in addition to questioning, the first reaction is: his engine quality is really good!

In general, engine overhaul is caused by severe wear and aging of internal parts, resulting in reduced power performance. In recent years, Cummins and the users have created one after another over one million kilometers without major repairs. On the one hand, the engine manufacturing process has been greatly improved, and on the other hand, more and more people have realized the maintenance. The importance of it.

what? Do not believe? look down.

Light card first person, 5 million kilometers in 5 years

A hardworking person from Xizhou, Shanxi Province, who came to Hohhot in the west of Shanxi Province, Mr. Zhang, started an Aoling light truck equipped with Cummins F engine in 2010, with live fish transportation as its main business.

In the first few years, Mr. Zhang went from Hohhot, Inner Mongolia to Wuhan, and traveled 3,000 kilometers. It takes three to four days to complete, plus busy business, often running on the road for one month. The engine naturally does not have much chance of stopping work, and only has time to rest during maintenance.

Mr. Zhang, who has ran for millions of years in 5 years

Until 2015, the light truck with the Cummins F-Series engine had already reached 1 million kilometers, and there was no overhaul in the middle. Five years and one million kilometers, which made Mr. Zhang and his colleagues very surprised.

In this regard, Mr. Zhang said frankly, thank you very much for the reliability and stability of the Cummins engine. Cummins F-Series engines feature an advanced Bosch high-pressure common rail fuel system with stable fuel injection pressure, low emissions and low fuel consumption. The modular construction increases engine reliability for ease of maintenance, low maintenance and service. It has high reliability and low maintenance cost, which brings high efficiency attendance and visible profit to users.

The Cummins engine and Mr. Zhang's mutual support have fulfilled the first million kilometers of light trucks without major repairs. Today, his second light truck with a Cummins F engine is still working, and the second breakthrough is only a matter of time.

Careful care, millions of kilometers still handy

Jixian County, Yangquan City, Shanxi Province is located at the edge of the northeastern part of the Qinshui Coalfield. The coal reserves are 3.7 billion tons and the distribution area is more than 340 square kilometers. Here, highway heavy trucks are the main tool for coal transportation. Mr. Guo is a member of the county's coal transportation army. He started driving at the age of 18 and now has 30 years of driving experience.

For many years, Cummins engine has been accompanied by Mr. Guo. The advantages of excellent quality, comfortable opening and low maintenance cost are all Mr. Guo’s experience for many years. Today, Mr. Guo bought three cars and hired nine drivers. Since the customer's demand for coal has always been high, the three cars are basically people who are not resting, so the high-intensity attendance rate is due to his maintenance of the engine.

30 years of driving experience has made him well aware of the importance of maintenance - he would rather run more, and regularly go to the regular service station of Dongfeng Cummins for maintenance on time, and resolutely use pure accessories. A semi-trailer in his hand was powered by the L375 engine produced by Dongfeng Cummins. It had already ran 780,000 kilometers at the beginning of 2018, and now it is about to reach the million-kilometer mark, and the key components such as the engine have never been Overhauled.

With the wind and rain, 2 million kilometers without overhaul

Mr. Liu from Taian, Shandong, purchased a Dongfeng Tianlong tractor in 2006 with an L-Series engine from Dongfeng Cummins. The car accompanied him for 13 years and ran over 2 million kilometers until the vehicle was scrapped and the engine was not overhauled.

Mr. Liu's car is equipped with Cummins L series 375 horsepower engine, which has strong power, powerful cargo, overtaking speed and low fuel consumption, which can save a lot of cost. In the past 13 years, there have never been major failures, and the reliability of Cummins has brought unexpected benefits to Mr. Liu.

He adheres to his own principles in maintaining the engine: insisting on maintenance only at the designated service station of the manufacturer, and only selecting pure accessories for maintenance; insisting on the modification of the original car circuit, try to find the service station professionals to deal with; never add oil to the small gas station You can't do anything to hurt the engine for saving money.

Mr. Liu recalled: "Tianlong Tianlong accompanied me for 13 years, more than 2 million kilometers. In retrospect, it has been a bit reluctant to run together for so many years. I feel very lucky, this 2 million kilometers is a big prize, buy lottery tickets. Not in the middle!" (This article is from Cummins China)
