Research and Development Needs for CNG Fueled Vehicles

A comprehensive examination of the research needed to accelerate the acceptance of compressed natural gas as a vehicle fuel has been conducted. The technical problems which have limited acceptance but which may be alleviated through research are poorer engine performance and reduced driving range as compared to vehicles using liquid fuels. A public perception that CNG is not as safe as gasoline for public use has been a problem. The identified research needs include specific projects which will reduce or eliminate these problems.
