Ricardo and Clean Air Power to partner on dual-fuel engines

Ricardo and dual-fuel engine specialist Clean Air Power (CAP) entered into an agreement for the development of the dual-fuel engine business. This agreement will combine Ricardo’s system integration expertise with CAP’s dual-fuel technology of compression ignited diesel engines that use natural gas with diesel pilot ignition.

CAP’s dual-fuel system enables heavy duty vehicles to operate primarily on natural gas, with diesel fuel acting as a “liquid spark plug”. The diesel engine is basically unchanged, and retains its high performance and high efficiency 4-stroke diesel cycle. If the natural gas runs out, the system changes seamlessly to operate on 100 percent diesel, providing complete diesel operational backup.

As system integrator, Ricardo will use its full vehicle knowledge, engine design and controls experience and system modeling capabilities to ensure that CAP’s dual fuel system meets the fit, form and function requirements of the complete vehicle.

Natural gas in a dual fuel application offers both fuel economy and cost savings to the large and heavy duty engine industry. This agreement will help our global clients to achieve those savings more quickly, with reduced development time and robust system integration. We are pleased to be working with CAP as a system integrator for their patented dual-fuel technology.

—Tom Apostolos, president of Ricardo’s US business Ricardo, Inc.
