EURO IV 6DL2-35E4

The EURO IV 6DL2-35E4 represents a significant advancement in commercial diesel engine technology, engineered by FAW Jiefang Automotive Co. Ltd’s Wuxi Diesel Engine Works. This robust powerplant combines proven mechanical design with advanced emission control systems, delivering the reliability commercial operators demand whilst meeting stringent European emission standards.

Technical Architecture

At its core, the 6DL2-35E4 employs a 4-cylinder in-line configuration with direct injection technology. The engine features a 108×120mm bore and stroke arrangement, yielding 4.4 litres of displacement. This compact yet powerful design maximises efficiency whilst maintaining the durability essential for commercial applications.

Power & Performance Characteristics

• Rated Output: 112kW at 2,500rpm
• Net Power: 110kW at 2,500rpm
• Peak Torque: 530Nm delivered between 1,300-1,700rpm
• Specific Consumption: 200g/kW·h

The engine’s torque characteristics prove particularly well-suited to commercial vehicle applications, with substantial pulling power available at relatively low engine speeds—essential for laden vehicle performance and fuel economy.

Advanced Combustion Systems

The 6DL2-35E4 incorporates common rail fuel injection technology, representing a considerable technological leap over conventional injection systems. Common rail technology allows for multiple injections and immense control over engine parameters, enabling extreme fine-tuning of combustion parameters. This precision fuel delivery system optimises combustion efficiency whilst reducing harmful emissions.

Each cylinder features 4 valves, improving breathing characteristics and enhancing fuel-air mixing. The turbocharged and intercooled induction system ensures adequate air supply across the operating range, maintaining power delivery even under demanding conditions.

Emission Control Technology

Meeting EURO IV standards requires sophisticated emission control strategies. The engine employs EGR (Exhaust Gas Recirculation) as its primary NOx reduction technology. EGR works by recirculating a portion of exhaust gas back to engine cylinders, reducing peak combustion temperatures and consequently NOx formation.

The implementation demonstrates engineering expertise, as EGR allows engines to fully take advantage of high pressure common rail systems whilst operating efficiently with low emissions near or below EURO IV limits. This approach provides a cost-effective solution for meeting emission requirements without compromising reliability.

Physical Specifications & Integration

The engine’s compact dimensions of 992×780×955mm facilitate integration into various commercial vehicle chassis configurations. At 560kg dry weight, the powerplant offers an excellent power-to-weight ratio, crucial for payload optimisation in commercial applications.

Acoustic performance remains well-controlled, with noise levels not exceeding 94dB(A)—important for operator comfort and urban operating restrictions.

Applications & Market Position

The CA6DL2 engine series primarily serves road trucks, engineering tractors, dump trucks and special purpose vehicles. Its robust construction and reliable performance characteristics have made it a popular choice amongst commercial operators seeking dependable motive power.

As part of FAW Jiefang’s comprehensive engine programme, manufactured by the Wuxi Diesel Engine Works which produces 150,000 diesel engines annually, the 6DL2-35E4 benefits from established manufacturing processes and extensive service support networks.
