The feasibility of using kerosene fuel in a spark ignited two-stroke engine was investigated. Primary effort was directed at comparing kerosene fueled performance to gasoline fueled performance and to overcoming cold starting problems with kerosene. The single cylinder research engine had fuel injection upstream of the reed valve and used loop scavenging. A vortex pneumatic atomizer was used to reduced the droplet size. The results of this study indicate that the vortex pneumatic atomizer helps reduce poor performance of the engine when using kerosene fuel. A method to overcome the cold starting problem with kerosene fuel has been developed, which involves heating the atomization air during start up.
