Product Overview
The WP4.6N diesel engine is a new-generation Weichai platform model integrating new technical results, meeting Stage V, India BS V, China Non-Road Stage IV and Stage IIIB emissions and suited to 3 t wheel loaders.
Product Advantages
- Adaptability. Operates from -25°C to 50°C and at 4000 m altitude; modular design makes servicing convenient.
- Performance. High low-speed torque, strong acceleration and high work efficiency, with maximum torque up to 624 N·m.
- Economy. A high-pressure common-rail system with high injection pressure and good atomisation gives a minimum fuel consumption rate 5 g/kW·h below competing products.
- Reliability. A ladder-type strengthened block with a strengthened one-piece cylinder head, validated by 20000 h of endurance testing across operating conditions to secure engine life.
- Comfort. Pilot and post injection optimised across the whole map with combustion noise comprehensively improved; a rear gear train keeps noise low.
