CUMMINS ENGINE
Cummins power: Supplies SHACMAN vehicles with custom built ISM series fully electronically controlled engines with intelligent controls, excellent power, five key steps in the global system and 1 million kilometers major maintenance free.
Cummins ISM series engines integrates the five key subsystem: Intake air handling system,combustion optimization system, electronic control system, fuel system, filtering system and post processing system.
Power ranges from 308 to 440 horsepower, maximum torque is rated at 2100 Nm and maximum rotation is rated at 2130 rpm.
Great low speed torque, fast acceleration, great climbing ability.
Weighs only 940 kilogram, great power to weight ratio.
New oil sump design reducing noise levels. Electronically controlled high pressure fuel system allowing high pressure atomization of diesel oil in cylinders and precise injection.
Electronic control system includes cruise control, vehicle speed control and over 100 other functions. The system makes sure the engine is in the best shape, features highly integrated module design and uses 30% less parts, greatly reducing failure rate.
Strong interoperability of spare parts, serialization of a high degree, easy repairs.
Ultra long filter and oil change interval, significantly reduce the cost of daily maintenance. The filtration system utilizes Cummins Fleetguard 1003 FS filter. Its 10 micron Stratapore filter technology is designed specifically for the protection of parts with filtering efficiency is high as 98.7%.
Intake and exhaust system uses Cummings HX55 Holset turbocharger. The waste gas bypass valve can be automatically adjusted according to the need of air flow, achieving four levels of control within the revrange and is best suitable for high power rated engine.
The use of the world's most widely used and the most mature heavy-duty diesel engine braking system ---- JACOBS engine brake system, The system can absorb 85% of the vehicle's inertia force with maximum braking capacity of up to 326 horsepower. Drivers are able to go downhill in a higher gear and thus increasing efficiency, The engine is not supplied with fuel while going downhill, even further increasing fuel efficiency.
