Abstract
The objective of this project was to develop a bolt-on natural gas conversion kit for the 6V-71 two stroke diesel engine used in most transit coach in Canada. For various reasons it was decided to try to improve on an existing mechanical conversion system instead of starting from new. An electronic controller and various other modifications were used to obtain better engine reliability and efficiency. This paper describes the final system and present both performance and emissions results obtained from dynamometer testing and also results of field testing.
