Determining the angle of advance of ignition when switching from petrol to gas depending on fuel mixture burning rate


The paper presents an algorithm of determining the angle of advance of ignition in case the engine is switched from petrol to gas fuel in accordance with the fuel mixture burning rate depending on many parameters and close to the actual physical processes taking place in combustion chambers of internal combustion engines. Tentative calculation of changing the angle of advance of ignition for compressed natural gas and liquefied hydrocarbon gas has been made. Possible errors and ways of their minimization as well as the order of implementing the algorithm when determining coefficients of the influencing parameters are shown.
