Abstract
The results of simulation and test stand investigations of 170.A1 engine fuelled by means of injection of liquid phase of propane-butane or pure propane and pure butane have been reported in article. In order to verify the simulation results the test stand with 170.A1 engine was prepared and equipped with the modified serial single point gasoline injection system. The own controller enabling engine work management was also elaborated and manufactured. The results of simulation and test stand investigations have been compared and discussed. The phenomena associated to the charge formation during the engine feeding with liquefied gas have been presented too. The comparison of chosen engine parameters for the given cases of fuelling confirmed the possibility of use of the evaporating heat of fuel to improve the cylinder filling and hence to improve the engine effective parameters.
