About Dual-Fuel Technology
Clean Air Power's Dual-Fuel technology enables diesel engines to operate with the low emission benefits of natural gas while retaining the inherent power, efficiency, low cost and long life of compression ignition engines. Dual-Fuel engines operate on both natural gas and diesel fuel simultaneously. During normal operation, the majority of the fuel burned is natural gas, while diesel fuel serves as a pilot for combustion. This combination of fuels produces substantially less oxides of nitrogen (NOx), particulate matter and greenhouse gasses than engines burning only diesel fuel without sacrificing diesel engine performance. Dual-Fuel technology combines the benefits of a diesel engine (quick response to load change, reliability, high efficiency and low cost) with the benefits of a natural gas engine (low emissions and typically lower specific fuel price) to provide a high performance, low emission, cost-effective, cleaner system that may also reduce fuel costs.
