Product Advantages & Features

Engine Block Structure: Jointly developed with Ricardo (UK) and Southwest Research Institute (SwRI, USA), featuring a high-strength engine block, integrated cylinder head, rear-mounted gear train, and front-end torsional vibration damper, delivering high reliability and low noise.

Fuel System: Equipped with a full set of BOSCH high-pressure common rail system and sensors, enabling precise fuel injection and mo

Low-Pressure Fuel System: Integrates automatic fuel priming and fuel heating functions to enhance low-temperature starting performance; three-stage fuel filter ensures higher reliability of the fuel system.

Cooling System: Adopts a high-efficiency cooling system design with a built-in engine cooling structure, multi-ribbed belt drive with automatic tensioning, and an electronically controlled silicone oil clutch fan, achieving high engine thermal efficiency and excellent heat dissipation effect.

ØEconomic Efficiency: Four-valve design, symmetrical combustion chamber, and central injector for excellent fuel economy.

Ø Power Performance: Excellent power output performance with a torque reserve of over 40%, highly responsive under load, and high operating efficiency.

Advanced Engine Power Management (AEPM): According to operating conditions, when the power exceeds the standard load, the diesel engine can temporarily boost its power to improve operating efficiency.

Multiple Power Output Interfaces: Multiple power output ports meet different main engine layout requirements.

After-Treatment System: Adopts the DOC+DPF+SCR technical route, offering split-type and in-line after-treatment devices for stronger adaptability to overall engine layout.
