EVO-MT® 9920 | LNG Conversion for Caterpillar 992 Wheel Loaders

The EVO-MT® System enables operators of Caterpillar 992 wheel loaders 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 duty cycle of the wheel loader. Typical DDR for most wheel loader profiles ranges between 35% and 50%. Wheel loaders converted to LNG + diesel operation exhibit diesel-like performance in such critical areas as power, response and efficiency.
