At a glance
The WP7H comes from an original Weichai diesel engine supplier and is built as an Inline unit, with 6.8 L displacement. Rated output spans 124–190 kW (169–258 Ps). Peak torque reaches 1050 N·m. It is supplied to meet China Non-Road Stage IV emission requirements. Typical duty is excavator service.
Product Overview
Upgraded from the WP6H’s 6.22 L to 6.8 L, with family styling for better power and competitiveness and a separated intake and exhaust structure for strong integration; output covers 124-190 kW with EGR and SCR routes available, suited to 20 t class excavators.
Product Advantages
- Low fuel consumption. Separated intake and exhaust design improves charging efficiency, optimises combustion and improves economy, with a low fuel consumption rate of 189 g/kW·h.
- Excellent NVH. A rear gear train and low-ratio gear set further reduce vibration and noise, 2-3 dB(A) below competing products.
- Strong power. Torque raised to 1050 N·m.
- Updated appearance. Family styling with tidier oil and electrical routing.
