Dongfeng Cummins ISL9.5-400E51A bus engine

Cummins ISL series 9.5-liter engine, power range of 292-400 horsepower, using Cummins XPI ultra-high pressure fuel injection system, variable fuel injection timing, achieve the full speed range and full load range of better combustion state, effectively reduce fuel consumption. Light WEIGHT, ADVANCED DESIGN makes the engine structure compact, the weight IS about 200 kg lighter than other products with the same horsepower, the transport efficiency is higher, widely used in 12 meters luxury tourist bus, etc.

The Surging power adopts the world’s leading Cummins XPI ultra-high pressure fuel injection system, the maximum torque is up to 1710N.m, to ensure that the vehicle is fully loaded and powerful in a variety of use environments; Low speed and large torque, even if the vehicle is fully loaded in potholes, soft road can also start easily and smoothly, climbing strong, and reduce the driver’s shifting times, reduce labor intensity; High speed and high power, in plain and high speed road vehicle acceleration is good, fast overtaking, save bus running time.

The world’s leading cummins XPI ultra-high pressure fuel injection system is our first choice for fuel saving. The injection pressure can be as high as 1800Bar, and the fuel consumption can be breakthrough reduced. The optimized electronic control calibration software makes the common working conditions of the engine all in the fuel consumption economic zone, the coverage rate of the specific fuel consumption economic zone is up to 80%, and the engine runs in fuel saving most of the time. EP fuel saving switch is standard. It can switch between the two modes according to the desire of fuel saving at any time by simple button. Under any working condition, the E gear can achieve fuel saving, and the P gear can achieve power.

Reliable and durable adhering to the excellent reliability of Cummins engine, a multi-functional, less parts greatly reduce engine failure; In view of the different domestic oil quality, the enhanced fuel filtration protection system is used to remove the water, iron oxide, dust and other debris in the fuel before the fuel enters the fuel rail, so as to reduce the blockage, rust and wear caused by the fuel injector, greatly reduce the fault of the fuel injection system, and ensure the stable operation of the engine.
