Clean Air Power's Legacy technology is a patented Dual-Fuel™ system which enables heavy-duty diesel engines to operate primarily on natural gas. This provides users with diesel engine performance, significant fuel cost savings and low emissions without sacrificing the diesel engine's characteristic efficiency or reliability.
Combining the Dual-Fuel™ system with an existing Caterpillar engine (1998-2002), gives you Clean Air Power's Legacy. Installations are available for a used truck, re-power or in a new Glider. Gliders are available from Peterbilt, Kenworth, Freightliner and Western Star.
C10 C12 C15
These engines all have met EPA standards and the C15 model is still the highest highest horsepower on-highway natural gas engine ever brought to market.
The application of Dual-Fuel™ technology does not require any major modifications to the existing engine platform. Clean Air Power's Hawk ECU receives the fuel command from the Caterpillar ADEM engine controller. The HAWK then re-calculates the correct amount of natural gas and diesel (diesel pilot), and the timing of the pilot injection. The natural gas is injected into the intake manifold and compressed with the air in the cylinder and is subsequently ignited by the diesel pilot.
In 1996, Clean Air Power entered into a license agreement with Caterpillar Inc. The relationship allowed Clean Air Power to develop and market Dual-Fuel™ conversions for their heavy-duty on-highway engines. The system was developed for CAT C15, C12 and C10 engine models. Sales have continued in both the USA and Australia. These engines all meet CARB and EPA standards and the C15 is still the highest horsepower on-highway natural gas engine ever brought to market.
