Sinotruk WD615 Series General Overview

The Sinotruk WD615 series is the classic flagship diesel engine platform independently developed by China National Heavy Duty Truck Group, designed exclusively for HOWO heavy commercial vehicles and stationary engineering equipment. All WD615 engines adopt a unified 9.726L inline six-cylinder, water-cooled, four-stroke, turbocharged & intercooled mechanical direct injection layout, with horsepower ranging from 266HP to 371HP to match diverse transport and working conditions.

With a total displacement of 9.726L, this engine delivers peak torque of 1100N·m at 1100–1600rpm, featuring outstanding low-speed torque output to adapt to harsh working conditions such as construction sites, mines and gravel transportation. Adopting four-stroke water cooling and direct injection design, it boasts simple mechanical structure, stable performance and low maintenance cost, perfectly matching HW15710 10-speed manual transmission for all HOWO classic heavy trucks.

Core Performance Advantages Of Sinotruk WD615 Series Engine

1.Ultra-Wide Torque Platform For Complex Road Conditions

Every Sinotruk WD615 engine maintains peak torque within 1100–1600rpm low-to-medium speed range. Drivers do not need frequent gear shifting during uphill climbing, heavy loading and highway cruising, delivering stable traction on mountain roads, mine gravel roads and long-distance expressways without obvious power attenuation.

2.Outstanding Fuel Economy To Cut Long-Term Operation Costs

Optimized mechanical fuel injection system reduces idle and full-load fuel waste. Global fleet clients report 7%-13% lower fuel consumption compared with competing same-horsepower heavy-duty engines. The low fuel loss characteristic effectively cuts monthly logistics operation expenditure for freight enterprises.

3.Extra High Durability & Low Malfunction Rate

Cylinder blocks, crankshafts and connecting rod assemblies of Sinotruk WD615 adopt high-strength ductile cast iron raw materials with reinforced structural design. Under standardized regular maintenance, the service life can exceed 800,000 kilometers, adapting to continuous high-load operation in harsh mining and construction scenarios.

4.Simple Mechanical Structure With Low Global Maintenance Threshold

Without complicated electronic control units and SCR exhaust post-processing components, WD615 engines can be fully overhauled with ordinary repair tools. Small local repair shops in Africa, Southeast Asia, Central Asia and South America can complete daily maintenance independently without professional electronic debugging equipment.
