With Kamms, an engine service provider, and TechnoEco, ComAp´s local service and commissioning partner, we have implemented ComAp´s bi-fuel solution that converts a conventional diesel engine to run primarily on gas, without compromising the engine´s power, durability, orlongevity.

"If we are thinking about the economic effects of our bi-fuel solution, on average, we are saving 35% of diesel by replacing it with gas," says Roman Slavik, Business Development Director, Russian Federation and CIS. The bi-fuel solution has been applied on more than 30 dump trucks in Novokuzněck, with more to follow.

The solution reduces diesel fuel consumption and lowers diesel-based emissions (NOx, PM, SOx, CO2).

The biggest challenge of this project was to deliver our solution and prove its seamless operation in extreme weather conditions where temperatures varied from – 40° C up to + 40° C. This project has shown that ComAp’s bi-fuel technology can be used in extreme environments and provides beneficial fuel efficiency improvements for a wide variety of industries, including mining.

The system consists of:

•  InteliBifuel control system (InteliBifuel Mobile and InteliBifuel Denox)
• A high-pressure gas train that prepares the gas before it is fed to the engine
• High-pressure gas injectors controlling the quantity of gas fed to the engine cylinders
• Sensors monitor all vital engine parameters to always ensure safe operation
