Features:

1. Core Specifications

• Configuration: Inline 6-cylinder, water-cooled, 4-stroke, electronically controlled high-pressure direct injection
• Displacement: 8.9 L; Bore × Stroke: 114 × 145 mm; Compression ratio: 17.3:1 (some sources list 17.7:1)
• Rated power: 239 kW / 325 HP @ 2200 rpm; Peak torque: 1260 N·m @ 1400 rpm
• Emission: China III / EU Stage IIIA (Tier III); Dry weight: ~738 kg

2. Design & Structural Features

• Integrated cylinder block and head design to prevent coolant and oil leaks
• Integrated oil/water plumbing replaces traditional hoses, eliminating leak risks
• Forged steel camshaft and crankshaft with a high-strength block; multiple components cast into the block for high rigidity, pressure resistance, reliability, and longer service life
• Platform-network honed cylinder bores combined with advanced piston-ring sets and crimp-formed gaskets to reduce oil consumption
• Around 40% fewer parts than comparable engines, significantly lowering failure rates

3. Fuel & Air Intake Systems

• High-Pressure Common Rail (HPCR) fuel system with multi-point injection — fast throttle response across rpm ranges, better power and fuel economy, lower noise
• Wastegate turbocharger (Holset) — smooth boost at low rpm with strong response, and stable power output at high rpm
• Turbocharged intercooling — maintains strong performance and efficiency under heavy loads

4. Electronic Control

• ECM electronic control system — intelligently switches operating modes based on environment and load conditions
• Built-in self-diagnosis, alarm, and remote monitoring functions
• Mature intelligent electronics allow application-specific engine customization

5. Reliability & Environmental Adaptability

• Three-stage fuel filtration — ensures balanced particulate dispersion, protecting key fuel-system components and maximizing engine life
• Excellent cold-start capability — easy starting even in severe cold (minimum start temp ~ -12°C, down to -25°C with auxiliary system)
• Strong fuel adaptability — suitable for applications worldwide
• Enhanced cooling and lubrication — further extends service life

6. Typical Applications

Primarily construction machinery: excavators, road rollers, bulldozers, cranes, water-pump sets, and engine power packs; also used in Dongfeng heavy-duty trucks. Optional Rear Engine Power Take-Off (REPTO) enhances remote equipment control.
