The constant increase in demand for energy and its carriers and the growing normative requirements in terms of eco-friendliness and reduction of CO2 emissions make it necessary to look for new sources of energy supply. Decreasing resources of conventional energy sources, including oil, the dynamic development of the road transport sector and the consequent increase in the number of vehicles on the roads have a negative impact on the air and environment. This makes it necessary to systematically increase the share of biofuels to minimise the negative environmental impact. It should be stressed that all new solutions must be sustainable and take into account the care of the environment. The manuscript analyses the possibilities of using alternative sources of automotive engine propulsion, with a particular focus on wood gas, petrol, methane and LPG (Liquefied Petroleum Gas). Using the example of a car equipped with the 1.1 Fire engine, a computer simulation has been developed to reproduce the NEDC (New European Driving Cycle) driving cycle. The simulation model used in the analysis was developed in Scilab environment. The computer simulation scheme consisted of five blocks taking into account the contour characteristics maps of the engine under analysis. As the results of the simulation have shown, when the engine is powered by wood gas, there is a significant drop in power. This is due to the much lower calorific value of wood gas and the lower air demand for the conversion of the fuel unit. Methane turned out to be a carrier with parameters more similar to those of conventional fuel. In this case, there has been a smaller decrease in the power achieved by the engine.
