Advantages of ISB3.9-125E40A Automotive Engine

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.
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.
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.
Advanced electronic control integrated system, large-capacity electronic control module, collect information from all drive train components such as electronic gearbox, ABS brake and ASR anti-skid through standard data bus, forming a seamless information flow…
