Algorithm of definition of a corner of an advancing of ignition at switching from petrol on gas for the controller of an electronic control system of the engine

The algorithm of definition of a corner of an advancing of ignition is offered at switching the engine from petrol for work on gas fuel according to speed of burning of a fuel mix dependent on many parameters, and approached to real physical processes occurring in chambers of combustion engine of internal combustion. The rough account of change of a corner of an advancing of ignition for komprimirt of natural gas and liquefied C H of gas is made. The possible errors and ways of their minimization, and also order of realization of algorithm are shown at definition of factors of influencing parameters.
