2019 is the birthday of Cummins The China Truck Network reporter learned on the spot that the power solution introduced by Cummins is an integrated and efficient powertrain for the heavy truck market, including the X-series and Z-series heavy-duty engines that are upgraded to the national six with industry-leading technology. And the North American market, and the latest in China's Eaton Cummins EndurantTM; automatic transmission.
“This solution will bring more value to users in terms of low fuel consumption, high efficiency, safety and intelligence.†Cummins, vice president and chief technology officer of China, introduced at the scene, “The Cummins power chain is in the economy and The power mode is deeply integrated, and it integrates the optimal calibration of the shift point, the intelligent management of the vehicle acceleration, and the intelligent management of the taxiing condition. Based on the powertrain analysis of big data, the power chain also realizes the application scenario. Optimization. In addition, engine brake power is optimized and provides predictive cruise, predictive shifting, smart taxiing, intelligent diagnostics and service."

As the source of this power solution, Cummins Z14's maximum power is increased to 441kW, the maximum torque is increased to 2750Nm, and the low-speed torque and maximum torque are the industry leading level. At the same time, the engine adopts low-friction power cylinder design, high-efficiency supercharger and high-torque and down-speed speed strategy to ensure further reduction of fuel consumption, saving 1-2%.
It is worth mentioning that the Cummins Z14 engine's predictive cruise function can realize intelligent speed control under multi-slope conditions and improve fuel economy performance based on the road map and the real-time position of the vehicle. According to the on-site technical personnel: "The Cummins Z14's intelligent torque function can automatically select the engine torque output characteristics according to the comprehensive information of the vehicle load and road front, and improve the fuel economy of the vehicle. At the same time, the intelligent sliding function of the engine is safe. The fuel economy can be achieved by smart driving under ramp conditions."

In terms of product reliability, the reporter learned that the Cummins Z14 engine uses a monolithic all-steel piston and incorporates an innovative integrated design that significantly reduces parts wear. The product has also completed the test of the extreme road test of over 6 million kilometers of high temperature, high cold and high altitude. At the same time, the engine uses the patented in-cylinder braking technology, the rated point is increased by about 25%, and the maximum braking power is up to 360kW, which greatly improves the operational safety.
With powerful power protection, the performance of the gearbox matched to the engine is also very important. The gearbox in Cummins' integrated powertrain solution is the Eaton Cummins EndurantTM automatic transmission, the lightest 2650Nm AMT transmission system on the market.
According to field technicians, the EndurantTM automatic transmission uses internal wiring of the electrical system to reduce the exposure and corrosion of the wiring harness and connectors, greatly improving the reliability of the system, and the intelligent prediction function of the transmission provides a clutch replacement reminder for the user to Arrange the maintenance plan well.

In addition, the product is equipped with an industry-specific transmission lubricant pressure sensor to prevent gear ablation due to low lubricant level. At the same time, the gearbox also uses forward-looking technology to perform predictive shifting of shift decisions, improving fuel economy and driving comfort, and providing SAE standard 8-hole bottom power take-off interface and gearbox The rear power take-off option is available to meet the diverse needs of customers.
With the debut of the Cummins Six-Card engine and the EndurantTM gearbox, Chinese customers will also have the opportunity to experience the efficient operation and driving experience of this industry-leading powertrain. While improving the power and reliability, the solution will help users reduce the total operating cycle cost, and further improve ride comfort and safety to achieve the best performance.
