EVO-MT® 7850 | LNG Conversion for Caterpillar 785 Mine Haul Trucks

The EVO-MT® System enables operators of Caterpillar 785 mine haul trucks to substantially reduce operational costs and improve sustainability by substituting diesel fuel with lower cost, cleaner burning natural gas. The EVO-MT® System is comprised of patented and proprietary technologies that allow haul trucks to safely operate on gas percentages that represent a substantial portion of their total fuel requirement. The EVO-MT® System has been designed around an LNG on-board storage capacity equivalent to 50% of the normal diesel fuel consumed over a single shift of operation. Diesel Displacement Rate (DDR) will vary according to the specific haul profile and duty cycle of the truck. Typical DDR for most haul profiles ranges between 35% and 50%. Trucks converted to LNG + diesel operation exhibit diesel-like performance in such critical areas as power, response and efficiency.
