In this article the analysis of working parameters of flexible fuel engine based on pneumatic fuel injection by means of hot exhaust gases in two-stroke engine are presented. This is a low cost in-cylinder fuel injection system for SI engines which is much simpler than alternatives. Author realized a system of pneumatic fuel injection by means of hot exhaust gases (according to conception of Pat PL95190B1) drawn from one cylinder during the working stroke and, following the addition of fuel, forced into another cylinder during the compression stage. Spraying and injection of fuel by means of hot exhaust gases give additional possibilities of complete evaporation of liquid fuels. In practice, a two-stroke internal combustion engine with spark ignition and pneumatic injection based on this strategy successfully uses liquid fuels with very different fractional and group composition (alcohol, alternative fuels with extended fraction and heavy fuels, such as diesel oil, kerosene and vegetable oil), which may be very beneficial from the viewpoint of practical realization of flexible fueling combustion system for special engines. The results of tests shown it is possible to reach a high repeatability of the fuel dose per cycle and maintaining uniform fuel doses for each cylinder. This is most significant factor for cooperation possibility and power control of combustion engine and electric machine in hybrid propulsion system.
