On April 14, Weichai hosted the launch event for its new generation of light power products for construction machinery in Yangzhou, themed "Reliable, Lightweight, and Extremely Fuel-Efficient." A full range of light power engines, including the Weichai WP3.2, WP3.6N, WP4.1, and WP4.6N, made a stunning debut, injecting Weichai's strength into the transformation and upgrading of the compact construction machinery market.

A Full Series Makes a Refreshed Debut

Comprehensive Performance Leap

Currently, the construction machinery industry is accelerating its transition toward higher efficiency, reliability, low carbon, and intelligence. As the application scenarios for compact construction machinery continue to expand, end-users are demanding higher reliability, fuel economy, and environmental adaptability from power systems.

Weichai's new generation of light construction machinery power systems covers a power range of 36.8-129kW. With comprehensively upgraded performance, they precisely meet the needs of customers in the compact construction machinery sector, including crawler excavators, wheeled excavators, and skid steer loaders.

As one of the core products featured at the launch, the WP3.6N excavator engine covers a power range of 48-92kW and delivers a maximum torque of 500N·m, characterized by high low-speed torque and excellent fuel economy; Equipped as standard with a dual-stage fuel filter and electric fuel pump, it demonstrates strong adaptability to various fuel qualities; An optional hydraulic reversing fan effectively removes debris from the radiator surface, resolving high-temperature issues and enhancing overall vehicle operational efficiency; The multi-PTO design provides a maximum output torque of up to 300N·m; Utilizes pilot injection technology and a high-precision meshing gear train to achieve low engine vibration and noise.

New Breakthroughs in Hybrid Products
