What Is DEF Fluid: The Complete Fleet Guide
Gas Diesel Engine
When you need reliable power generation that adapts to changing fuel conditions, our gas diesel engines deliver unmatched flexibility for industrial applications. These dual-fuel powerplants represent decades of engineering refinement from FAW Jiefang Wuxi Diesel Engine Plant, where we’ve been building engines since 1943.
Our gas diesel engine lineup runs on both natural gas and diesel fuel, giving operators real control over operating costs and emissions. The engines automatically switch between fuels based on load demands and availability. During startup and low-load conditions, they run on diesel for stable combustion. As loads increase, the system introduces natural gas while maintaining a small diesel pilot injection for ignition. This approach cuts fuel costs by up to 40 percent compared to straight diesel operation.

The heart of these engines lies in our electronic control systems. We’ve integrated smart fuel mapping that monitors combustion pressure, exhaust temperature, and knock sensors to optimize the gas-to-diesel ratio in real time. The result? You get diesel-like power density with natural gas economy. Our 6-cylinder models produce between 250 and 420 horsepower, while maintaining thermal efficiency above 42 percent across the operating range.
These engines excel in stationary power generation, marine propulsion, and heavy equipment applications. Mining operations particularly benefit from the dual-fuel capability, since they often have access to wellhead gas or pipeline natural gas. The engines meet China National Stage IV emissions standards and can achieve even lower NOx levels when running primarily on natural gas.
Every engine leaves our Wuxi facility with comprehensive testing data. We run each unit through a 4-hour break-in cycle, followed by full-load testing on both fuels. This ensures consistent performance whether you’re powering a generator set in remote oil fields or driving pumps at a water treatment plant. With proper maintenance, these engines deliver 20,000+ hours between major overhauls, making them a solid investment for continuous duty applications.
