Engineering Excellence in Compact Design
The EURO III 4DL1 diesel engine series stands as a testament to modern automotive engineering, representing the culmination of decades of refinement by FAW Jiefang’s Wuxi Diesel Engine Works. This sophisticated powertrain delivers robust performance in a surprisingly compact package, measuring just 955 × 820 × 960mm and weighing 620kg.
Advanced Powertrain Technology
At the heart of the 4DL1 lies a meticulously engineered 4-cylinder in-line configuration with direct injection technology. The 110mm bore and 135mm stroke create a total displacement of 5.13 litres, optimally balanced for both power delivery and fuel economy. Each cylinder features four valves, ensuring exceptional breathing characteristics and combustion efficiency.
The engine’s turbocharged and intercooled design maximises power output whilst maintaining excellent fuel consumption figures of just 196g/kW·h across all variants. This efficiency stems from the sophisticated common rail fuel injection system, which precisely controls injection timing and pressure for optimal combustion under varying load conditions.
Performance Variants for Diverse Applications
Four distinct power configurations cater to different operational requirements:
- CA4DL1-18E3: 139kW (186hp) with 650Nm torque
- CA4DL1-19E3: 143kW (192hp) with 650Nm torque
- CA4DL1-20E3: 154kW (207hp) with 780Nm torque
- CA4DL1-21E3: 158kW (212hp) with 780Nm torque
All variants deliver peak torque between 1,300-1,700 rpm, providing excellent low-end pulling power essential for commercial vehicle applications.
Environmental Compliance and Reliability
Meeting stringent Euro III emission standards, the 4DL1 achieves smoke opacity levels ≤0.5m⁻¹ whilst maintaining operational noise below 94dB(A). This environmental responsibility doesn’t compromise durability – the engine is built to withstand demanding commercial use with proven reliability backed by FAWDE’s extensive manufacturing experience.
Quality Manufacturing Heritage
Manufactured at FAW Jiefang’s state-of-the-art Wuxi facility, each 4DL1 engine benefits from world-class production standards and rigorous quality control processes. This ensures consistent performance and longevity, making it an ideal choice for operators demanding reliable, efficient diesel power for medium-duty commercial applications.
