[Why do you love to use Cummins engines regardless of domestic and imported trucks? What’s so good about it?]

Cummins Technology Center not only has strong engine technology development capabilities, but also has strong vehicle engineering development capabilities. As an independent engine manufacturer, Cummins has industries in 190 countries and regions around the world, and has cooperated with almost most of the truck manufacturers on the planet. The European and American markets include Freightliner, Peterbilt, Navistar, and Volvo. , Scania, Mercedes-Benz, etc.
The layout of the domestic market is also more complete. There are 6 pure engine joint ventures, including truck engine factories that we are familiar with, such as Dongkang, Fukang, Xikang, and Ankang. At the same time, Cummins has also established domestically. Manufacturers of engine units, engine parts, etc. have formed a relatively complete production chain.
It can be said that Cummins has obtained a large amount of experience and engineering data through cooperation with this series of OEMs, and these data can support the research and development of Cummins engines and the ability to speed up localization adaptation, ensuring that Cummins can be used in every region. Adjust products that are adapted to the local area.

[Why is Cummins the truck driver’s favorite engine?]

① Reliable and durable: Cummins National VI engines have accumulated more than 20 million kilometers of actual road tests to ensure reliability and worry-free in practical applications;
② Clean and environment-friendly: Cummins National VI engine realizes improvement of fuel efficiency while reducing emissions;
③ Efficient and safe: all series of products apply engine braking technology;
④ Easy to use: Cummins National VI products achieve a long service cycle, and at the same time support functions such as remote intelligent diagnosis and remote calibration upgrade.

[Why is Chongqing Cummins engine so famous?]

Chongqing Cummins Engine Co., Ltd. is a joint venture with Cummins Corporation of the United States. It mainly produces three series of high-speed, high-power diesel engines and marine power units imported from Cummins Corporation of the United States with world-leading levels of N, K and MII. The power coverage is 145/1343KW.

Chongqing Cummins generator sets are widely used in power supporting fields such as trucks, buses, construction machinery, petroleum machinery, Cummins generator sets, ships and rail vehicles. Its advanced economy, power, reliability, durability and environmental safety are generally welcomed by users at home and abroad.
The technology of Chongqing Cummins Engine Co., Ltd. develops simultaneously with Cummins Corporation of the United States. It has passed the ISO9001: 2000 international quality certification audited by BVQI in France. It has been rated as one of the top 50 industrial enterprises in Chongqing for eleven consecutive years.
As the world’s number one diesel engine brand, “American Cummins” adopts the “building block” design mode and integrated design principles to integrate multiple functional parts into one part. One piece has many functions, just like an electronic integrated circuit. Advanced technology has created Cummins’ high quality, compact body size, 40% fewer parts than ordinary generators, and 20%-30% lighter weight than ordinary generators. Adopt Bosch Ve pump with cold start advance device, good reliability. Low fuel consumption. Lean matching also makes Cummins diesel generator sets significantly fuel-efficient, with an average fuel saving of 20%-30% compared with common brand units.
The point is that Chongqing Cummins generator sets are not only energy-saving and environmentally friendly. Dongguan Kangchai Electromechanical Equipment Co., Ltd. is the official authorized generator complete assembly production base of Cummins in the United States. The company has strong technical strength, a global network of spare parts and diesel generator set procurement system, currently has many branches, and is a modern high-tech enterprise integrating R&D, production, sales, maintenance and engineering.

[Advantages and disadvantages of Cummins engine]

Disadvantages: In fact, people who use them generally think that there are few disadvantages for imported engines. If you insist on the disadvantages, it is that if maintenance and repairs are required, the cost of Cummins engine parts is very high. Sometimes the car just When starting, there may be slight blue smoke occasionally, and after the engine has been used for a long time, there may be a phenomenon that the ignition will not come out. Advantages: The biggest advantage is less whistle, low fuel consumption, durable, and not easy to break down. Simply put, the quality of Cummins is very good. It is worthy of the trust of users. In fact, everyone who uses it knows that the engine is like the human heart. The simple manifestation of the quality of the engine is that it is best to turn the number of revolutions in a few seconds when stepping on the accelerator, and at the same time require good acceleration performance.

[Why is the cost of Cummins engine parts high]

1. The parts of Cummins diesel engine are supplied by Cummins headquarters, which are usually difficult to buy, so the price is higher than that of ordinary engines.
2. The structure of Cummins diesel engine is very fine, and it takes a lot of labor cost and maintenance time to repair it, so it is expensive.

[Why does a slight blue smoke occasionally appear when the engine is just started]

The blue smoke from the car may be the valve oil seal of the car. In addition to the problem, it may be cracked due to aging. At this time, the engine oil will pass through these cracks, penetrate into the combustion chamber, and then be burned, and the car will emit blue smoke. In addition, if the car’s engine oil is added too much, it is also easy to cause the car to burn engine oil. Too much engine oil is easily taken into the cylinder, and the phenomenon of burning engine oil will also occur.
When starting the engine, the engine oil in the cylinder will burn under the action of high temperature and high pressure to produce a large amount of blue smoke. This fault only needs to be replaced by the valve oil seal.

[After the engine has been used for a long time, it may appear that the ignition will not come out]

1. The storage battery is insufficient, which makes it impossible to drive the starter to run, thus failing to start the ignition.
2. Problems with the fuel supply system, such as no fuel in the fuel tank or blocked pipelines, or failure of the fuel delivery pump to deliver fuel, resulting in failure to start the ignition.
3. Problems with the air intake system, such as blocked air intake, excessive dust accumulation in the air filter or damp.
4. Insufficient compression force of the engine, such as serious wear of the cylinder liner, carbon formation of the piston ring, etc.
