About Hybrid Fuel Systems

Hybrid, formed in 1996, holds a worldwide license to commercialize a patented system for the conversion of diesel stationary or vehicular engines to non-petroleum based fuels such as natural gas. The company's technology is based on a series of patents and patents pending.

The licensed technology is illustrated in five U.S. patents and one patent pending. The company's initial commercialized application is a snap-and-play electronic retrofit device to convert medium- and heavy-duty engines to operate in a dual-fuel 70% natural gas and 30% diesel mode. A new generation of management has transformed Hybrid from a developmental-stage company with proprietary products for dual-fuel conversion in various stages of development to a company with the ability to deliver these products worldwide.
