Product Advantages
ISD series engines have been “model” products among the similar products in the industry with their exceptional reliability. ISD series engines have become the first power choice of domestic mainstream truck manufacturers with their stable and dependable product platform and sustainable technological development advantages, due to increasingly stringent emission regulations .
ISD series 4.5L and 6.7L engines with full-authority electronic control, ranging from 160-300 horsepower, are widely used in cargo trucks and municipal trucks with gross weight below 25 tons. ISD series features high operation efficiency, long work cycle, and good durability. The engines are equipped with advanced electronic control system to realize digital intelligent management of various engine systems such as air intake, exhaust, fuel, brake and aftertreatment, and real time data sharing between engine and subsystem and that between engine and vehicle, meawhile realizing realtime monitoring and pre-warning of faults.
Since their entrance into the market, ISD series engines have become favored by OEM and users by virtue of their higher output per liter, lower fuel consumption, longer overhaul interval and lower usage cost, as well as their advantages in energy saving and environmental protection.
Intelligent electronic controls
Advanced electronic control integrated system 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, more complete combustion, broader economical fuel consumption zone, tremendously enhanced fuel economy, thus further improving low-speed performance, and resulting in better noise reduction and cold start performance.
Excellent power output
Fast startup, good acceleration and gradeability, superior torque output at low speed.
Economical usage
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 and easy to upgrade. As of the end of 2010, Cummins Emission Solutions factories have supplied over 300,000 sets of selective catalytic reduction system (SCR) to worldwide engine enterprises, for Euro V, EEV and US EPA2010 emission solutions, with proven and approved reliability.
