Clean Air Power is the global leader in Dual-Fuel™ technology, enabling heavy-duty trucks to run on natural gas with 100% diesel fall back.
Clean Air Power is the developer and global leader of Dual-Fuel™ combustion technology for heavy-duty diesel engines. The flagship technology is a patented Dual-Fuel™ system which enables heavy-duty diesel engines to operate on a combination of natural gas and diesel. This provides customers with diesel engine performance, significant fuel cost savings and low emissions without sacrificing the diesel engine’s characteristic efficiency or reliability.
Founded in 1991, Clean Air Power has continually developed innovative technologies that allow clean natural gas to be the primary fuel source for heavy duty diesel engines. Clean Air Power's Dual-Fuel™ technology has already been fitted to more than 2,500 vehicles around the world. Continuing to be an active technology developer with 66 patents held and pending, Clean Air Power is pioneering the move towards heavy-duty natural gas trucks. Dual-Fuel™ technology enables heavy duty diesel engines to operate on a high proportion of natural gas. The diesel engine is unchanged and operates according to the diesel cycle, using a small "pilot" injection to ignite a controlled mixture of gas and air. This technology uses the diesel fuel as a "liquid spark plug" and natural gas as the primary fuel source. Dual-Fuel engines feature an Engine Control Unit (ECU) developed by Clean Air Power, and the diesel Electronic Control Module (ECM) to precisely control diesel, natural gas and air mixtures to optimize combustion, performance and emissions.
