Cummins ISL series 8.9L full-authority electronic control engines, ranging from 290-380 Hp (213-280 Kw). Compared to engines with same displacement, these engines are lighter and only weighs 704 kg, with more compact structure and higher power. Featuring ultra high output per liter and low speed torque, ISL's power can be as good as heavy-duty engines with larger displacement. With stable and reliable performance, durability and supreme fuel economy, ISL can greatly increase carrying capacity and operation efficiency of vehicles, thus becoming an ideal power choice of heavy truck, tractor and 11-14 meter-long highway bus, tour bus, public transit, school bus applications.
Leading manufacturing technology
Integrated design of cylinder block and oil circuit, forged crankshaft with high tension steel, highly durable pistons and liner with special surface treatment process all ensure the engine's reliability and durability.
Advanced electronic intelligence platform
Electronic control module with ultra large capacity share information among high speed datalinks, to ensure that the engine maintains the best operating status, effective fuel savings and low emissions under various loads.
Effective fuel saving
With higher injection pressure up to 1600 bar, High Pressure Common Rail Fuel System features more precise control of injection timing and amount of fuel, further improving low-speed performance and cold start performance.
Excellent power output
Fast startup, good acceleration and gradeability, superior torque output at low speed。
Highly integrated engine subsystems can realize excellent power, ultra long service life, and long maintenance intervals.
Leading emission level
The NS V version is developed on the same platform as EEV version, featuring high durability and reliability. It can be upgraded to meet Euro V/EEV standard by adjusting its urea injection amount and upgrading the aftertreatment system, complicated structural adjustment is not necessary.
