Natural Gas as a Stationary Engine and Vehicular Fuel

There is growing interest in using natural gas in vehicles in the U.S. and worldwide. Factors driving this development include desire for domestic energy use and diversification, reduced emissions, and fuel cost savings. As an engine and vehicle fuel, natural gas has many favorable characteristics as well as attributes that present technical and market challenges. A primary element of addressing these challenges is understanding the chemical and physical properties of natural gas and knowledge of the possible ramifications associated with gas composition variations.
