The X series 12-litre and 15-litre two heavy-duty diesel engines are produced at the Cummins X-Series engine plant (Cummins Jameson Engine Plant) in New York, USA. It is one of the most important Cummins production plants in the world, and it is the global ranking. The top 5 heavy-duty engine manufacturing base. So, what are the technical genes that make the Cummins X-Series engines recognized by the North American truck industry as standard super truck power? Senior technical engineers from Cummins of the United States introduced us to the technical innovations and technological achievements of the X-Series engines.
First, engine quality is optimized and durable and reliable
The X12 engine is based on Cummins' new platform. The weight of the engine determines the weight of the vehicle to a certain extent. In order to reduce the weight of the entire vehicle, it is required to reduce the weight of the engine as much as possible, but at the same time ensure the reliability of the engine. The combination of lightweight materials and advanced structural design concepts can avoid adding unnecessary weight, but also ensure strength and achieve optimal engine quality. The 930Kg weight of the X12 engine is more than 100 kilograms lighter than competitors' products of the same class, forming its own unique advantages. The X12 engine's key parts and components are strengthened, and the integrated steel piston improves durability. The new technology of diamond-like piston pin and oil ring reduces oil consumption and improves the adaptability and durability of the power system.
Second, the engine is operating efficiently and economically
The X12 engine has an in-line six-cylinder design and has a displacement of 11.8 liters and a horsepower range of 350-500 hp (260-375 kW). The X-Series has the highest lift in the world's 10-15 L engine displacement range, enabling low-speed high-torque operation. The maximum torque output of 2300N·M can be released when the speed reaches 1000rmp. The maximum torque can be released in the range of 1000 to 1400 rpm. For the power requirements when the vehicle is heavily loaded, it can be easily satisfied. In addition, up to 2000Bar XPI ultra-high pressure injection technology, fuel atomization is good, Leak less pressure maintenance technology to achieve more precise control of the amount of fuel, combustion more fully, improve fuel efficiency, more fuel-efficient; improve the secondary friction, improve fuel The economical, compact and efficient post-processing system reduces pipe wrapping, reduces energy consumption for thermal management, and further reduces fuel consumption. The key components of Cummins X12 engine are reinforced with integrated steel piston to improve durability. The new technology of diamond-like piston pin and oil ring reduces oil consumption and improves the adaptability and durability of the power system.

Third, the engine intelligent auxiliary system
The Cummins X12 engine uses three smart technologies, namely ADEPT intelligent assisted driving technology, PowerSpec intelligent vehicle management technology, and Connected Diagnostics remote service technology. Cummins ADEPT forward-looking intelligent assisted driving technology can realize the optimization and upgrade of the entire electronic control performance, and has the “high IQ†function that can dynamically adapt to various working conditions such as intelligent torque adjustment, intelligent coasting control, and forward-looking cruise control. When the user uses the automated manual transmission, the system intelligently uses load, speed, and road gradient sensor technology to automatically adjust the output speed, power, and gear position to optimize the vehicle's power efficiency and achieve the highest fuel economy improvement of 4%. At the same time, the integrated design of Cummins high horsepower compression braking and high integration of the engine can further increase the braking force to 400 horsepower, and the brake is safer.
Fourth, the X15 engine is stronger than the X12 power
The X15 engine is an upgraded version of the ISX15. The engine is optimized for compression ratio, intake and exhaust systems and combustion processes. Compared with the ISX15 engine introduced in 2010, the fuel economy is improved, the maintenance cost is reduced, and the engine is compatible with the United States. Environmental Protection Agency (EPA) emissions standards for 2017. Since it is a powerful engine that is even more powerful than the X12 engine, it certainly has extraordinary performance. The X15 engine is tuned to the performance version engine and the high-efficiency engine according to the power output demand.
The high-efficiency engine has a horsepower output range of 400p-500p, which ensures high fuel economy while ensuring extremely fast engine response speeds. The maximum output torque can reach 2508Nm at 1100rpm. At the same time, through the use of Cummins patented ADEPT, SmartCoast and cruise pre-control technology, the truck's handling performance will be further improved, and the fuel consumption can be further reduced by 6%. The high-efficiency version of the engine is mainly used in long-haul trucks, and it is engaged in interval transportation work. Like the performance version of the engine, the engine is also equipped with a telematics system that can be programmed, customized, and diagnosed wirelessly in an intelligent management system. With Cummins dedicated programs, users can upgrade their own engine system to the latest official settings without having to send the truck to the service station.
The performance version of the engine has a horsepower output range of 485 to 605 hp, which provides an ideal power match for long-distance heavy-duty trucks, making the truck more powerful at full load or climbing, and the engine's maximum output torque can reach 2780 Nm. The maximum torque speed range is relatively wide. In addition, engine braking has become even more powerful, with 450 bhp at 1500 rpm and 600 bhp at 2100 rpm. Its intelligent management system can give the vehicle a good choice of driving modes through engine work, further enhancing the efficient, safe and economical transportation of the vehicle.
