Abstract
A method of running an internal combustion engine with alternative fuels such as high or low octane gasoline, paraffin, diesel oil, ethanol, methanol or similar fuels and/or mixtures thereof and combustible gases such as LP-gas and the like at unchanged compression ratio, and which each motor cylinder can be supplied with a further medium besides the fuel for running of the engine and the fuel is heated by the heat from the exhaust system (22, 23). The invention also refers to an internal combustion engine for alternative fuels. This object has been achieved by proportioning and distributing the fuel to each motor cylinder in relation to the air sucked up and that the fuel before entering the motor cylinder is heated to a temperature between its flame temperature and above its evaporation temperature and that the evaporated fuel is fed to the respective motor cylinder preferably at a flat tangential interjection angle and when using low octane fuel as an extra medium water or a mixture of water and an antifreezing agent is injected in controlled amounts at a steeper injection angle inside the path of the fuel.
