The 3.9-liter Cummins B-series engine is characterized by in-line cylinders with four valves per valve, turbocharged with intercooled air and a common rail direct fuel injection system.
The main advantages of the motor are economy. Complete combustion of the fuel is ensured by the injection system, the fuel distributor and the exhaust after-treatment system. This ensures the demand for such power plants. Power and torque can reach maximum values even at low shaft speeds.
