EURO IV 6DM2-42E4

The EURO IV 6DM2-42E4 represents the pinnacle of heavy-duty diesel engineering from FAW Jiefang’s Wuxi Diesel Engine Works. This sophisticated powerplant delivers exceptional performance whilst maintaining strict environmental compliance through advanced emission control technology.

Engine Architecture & Performance

At its core, this engine features a robust 6-cylinder in-line configuration with direct injection technology. The precisely engineered bore and stroke dimensions of 123×155mm create an impressive 11.04-litre displacement, generating substantial power output across a broad operating range.

The engine produces a formidable 312kW (418 horsepower) at 1,900 rpm, with net power output reaching 309kW (414 horsepower). Peak torque delivery of 1,900Nm is achieved between 1,100-1,400 rpm, providing the substantial pulling power essential for heavy commercial applications.

Advanced Technology Integration

The 6DM2-42E4 incorporates cutting-edge turbocharging and intercooling systems, working in harmony with common rail fuel injection technology. This combination ensures optimal combustion efficiency whilst maintaining responsive throttle characteristics across all operating conditions.

Each cylinder features four valves, maximising breathing efficiency and contributing to the engine’s impressive fuel economy of just 190 g/kW·h. This efficiency translates directly into reduced operating costs for fleet operators.

Environmental Compliance

Meeting stringent EURO IV emission standards, the engine utilises advanced Selective Catalytic Reduction (SCR) technology. This sophisticated aftertreatment system converts harmful nitrogen oxides into harmless water and nitrogen, ensuring compliance with environmental regulations whilst maintaining performance integrity.

Smoke emissions are kept to exceptionally low levels at ≤0.3 m⁻¹, whilst acoustic emissions remain under 94.6 dB(A), making it suitable for urban operations where noise restrictions apply.

Construction & Specifications

The engine’s compact yet robust design measures 1,365×775×1,180mm and weighs 1,050kg, making it suitable for various commercial vehicle platforms. The construction reflects decades of engineering expertise from one of China’s most established diesel engine manufacturers.

This powerplant represents proven reliability and performance, backed by FAW Jiefang’s extensive global distribution network and comprehensive after-sales support structure.
