Key features

• 13 L displacement in the 338–412 kW band, covering the upper end of Weichai's commercial diesel truck range.
• 2550 N·m of torque available from 950 rpm — strong pull at low engine speed on grades and under load.
• Same engine platform offered at Euro III, Euro V and Euro VI ratings, so one vehicle program can be prepared for different markets.
• Built for vocational duty cycles: frequent load changes, dust, heat and stop-start operation.
• Matched natively with FAST twin-countershaft transmissions and HanDe axles within the SDHI driveline.

Applications

The WP13 targets vehicles that work outside on highway duty cycles — loaders' feeders, mine-site service trucks and special-purpose chassis where low-speed torque and cooling capacity matter more than flat-out cruising speed.

Customization

Available on request: rating and emission calibration for target-market homologation, cooling pack configuration, PTO interfaces, power take-off drive variants, export documentation and parts supply arrangement. Minimum order quantities apply for special calibrations.
