The D9B380 offers outstanding traction performance and high low-rpm torque. It ensures outstanding driving performance and instant availability when paired with a broad rpm range. The engine’s noise and exhaust emissions are also minimal. The engine can meet Euro 4 standards thanks to exhaust gas treatment using Selective Catalytic Reduction (SCR) technology.
The air compressor, fuel pump, oil pump, and power steering pump are all powered by a camshaft actuator at the back of the engine. This lightweight design is incredibly sturdy, quiet, and small. The engine cooling system also performs better because the intake air flow is unhindered by the rear-mounted camshaft drive.
