Dongfeng Cummins ISL9.5-400E51A bus engine

Parameter configuration
Product advantages
Cummins ISL series 9.5-liter engine, power range 292-400 horsepower, using Cummins XPI ultra-high pressure fuel injection system, variable fuel injection timing, to achieve a better combustion state in the full speed range and full load range, effectively reduce fuel consumption. Light weight, advanced design makes the engine structure compact, the weight is about 200 kg lighter than other products with horsepower, the transportation efficiency is higher, and it is widely used in 12 meters luxury tourist buses.

Surging Power adopts the world’s leading Cummins XPI ultra-high pressure fuel injection system, with a maximum torque of up to 1710N.m, ensuring that the vehicle is fully loaded and surging in various use environments; Low speed and high torque, even if the vehicle is fully loaded on potholes and soft roads, it can start easily and smoothly, climb the hill with strength, and reduce the number of shifts of the driver and reduce the labor intensity; High speed and high power, vehicle acceleration in plains and high-speed roads, fast overtaking, saving the running time of passenger cars.

The world’s leading Cummins XPI ultra-high pressure fuel injection system, the injection pressure can be as high as 1800Bar, the fuel consumption can be a breakthrough reduction; Optimized electronic control calibration software, so that the commonly used working conditions of the engine are all in the fuel consumption economic zone, the coverage rate of the specific fuel consumption economic zone is as high as 80%, and the engine is running fuel saving most of the time; Standard EP fuel saving switch, through a simple button switching, at any time according to the desire to save fuel in the two modes to switch, in any working conditions, E gear can achieve fuel saving, P gear can achieve power.

Reliable and durable Adhering to the excellent reliability of Cummins engines, one piece of multi-energy, less parts greatly reduces engine failure; In view of the different conditions of domestic oil quality, the enhanced fuel filtration protection system is adopted to remove the moisture, iron oxide, dust and other debris in the fuel before the fuel enters the fuel guide rail, reducing the injector blockage, rust and wear caused by it, greatly reducing the failure of the injection system and ensuring the stable operation of the engine.
