400KW Diesel Generator Set With Weichai Engine

The Weichai 400kW standby generator set is powered by the star engine model WP13D440E310 diesel engine. This model is derived from the WP13 platform, which has been validated by millions of units in the market, inheriting its core traits of reliability, high power, and economy, and is optimised specifically for power generation conditions to precisely match cutting-edge road technology with power generation requirements. The generator set delivers 400kW standby power with a 12.54L displacement, leading in power density in the industry; its lightweight body at 3118kg combined with compact dimensions of 3200×1345×1884mm balances performance, space, and energy consumption. Leveraging Weichai's technological expertise and quality control, it has become a preferred choice for medium-sized commercial and industrial standby power with high cost-effectiveness and reliability.

Product Features

• Proven Reliability from Road-Truck Heritage: Powered by Weichai's WP13 "Golden Power" platform, a globally proven solution with over one million units in service across heavy-duty commercial vehicles. Specifically enhanced and optimized for power generation applications, it boasts an extended B10 life, low failure rate, and delivers the same stable performance as trusted commercial vehicle powertrains.

• Exclusive High Efficiency & Energy Savings: Equipped with Weichai's next-generation high-pressure common rail fuel system, featuring injection pressure exceeding 2000bar for precise fuel metering and ultra-fine atomization. Combined with efficient turbocharging and intake management technology, it achieves industry-leading combustion efficiency and excellent fuel consumption across full load ranges, significantly reducing long-term operational costs for users.

• Industry-Leading Power Density & Compact Design: Inheriting the lightweight and compact design concept of commercial vehicle engines, the WP13 powertrain offers outstanding size and weight advantages in the 400kW class. It greatly saves equipment room space, lowers installation foundation requirements, and is ideal for space-constrained or rapid-deployment scenarios.
