However, when many users upgrade their vehicles from more than 300 horsepower to more than 500 horsepower, they still have concerns that the increase in fuel consumption will reduce the economic benefits of high-power trucks. Xiao Bian tells everyone here: As long as the engine is selected, high horsepower may not be costly.
Big horsepower does not necessarily cost
The relationship between load and horsepower
There is a scientific formula for vehicle load and vehicle horsepower matching: coefficient x weight.
In the domestic market, the matching coefficient of the traditional engine horsepower and vehicle full load quality is 7, that is, 50 tons of car with 350 horsepower.
In foreign countries, the coefficient is 10, 40 tons of the car will be equipped with 400 horsepower. This is why the engine horsepower of imported cars was above 400 horsepower.
This coefficient of the foreign engine market is not arbitrarily determined, but it is ultimately determined based on a large number of tests and actual use. It is obtained through scientific research and is more in line with the data on efficient economic transportation needs.
Dongfeng Cummins achieves high horsepower and fuel efficiency
The overall design of the Dongfeng Cummins ISZ13 engine is based on the big data of the international logistics market, responding to the ever-increasing timeliness demand in the Chinese logistics market, and entering the high-power tractor segment market. Concerning the user's concerns about high-powered engine fuel consumption, "Concordia" has many unique features to solve problems for card users.

More optimized fuel consumption curve
Dongfeng Cummins optimized the fuel consumption curve for the transport characteristics of high-powered tractors. At present, the engine speed of a large horsepower tractor is generally 1000-1200 rpm under normal operating conditions, and the normal operating speed is around 1100. The Dongfeng Cummins technical team has specifically optimized the fuel consumption curve for this rpm region. The fuel economy of the optimized product is 2-3% better than other products.

Standard EP fuel saving switch
ISZ13 engine, its fuel economy switch is divided into economical gear (E gear) and power gear (P gear) two gears, through a simple button switch, the driver can at any time according to their own desire to save in two different engines Switching between operating modes further enhances the engine's power and acceleration control.
Dongfeng Cummins ISZ13 engine comes standard with EP-saving switch
Dongfeng Commercial Vehicle and Dongfeng Cummins have optimized the ISZ series engine and throttle response. Under normal operating conditions, they can generate greater dynamic performance. When the throttle is small or the throttle is in full throttle, it can demonstrate its performance advantages. The engine has a large horsepower and the reserve power is high. It is possible to quickly enter the car at a high speed when the throttle opening is not too large. When driving at high speeds, with a small speed ratio rear axle or overdrive, the high-powered engine can make the car run to more than 80 yards even if the speed is not high, and the natural fuel consumption is low when the speed is reduced.
It's not just the users who are savvy, but Dongfeng Cummins is even more ahead of the users, thinking about what the users think and playing the cards of economical fuel economy. The Dongfeng Cummins ISZ13 engine has strong power, stable performance and fuel-efficient economy. It has become a leader in the high-powered truck market, leading the technological trend of high-horsepower truck engines!
