摘要
Realization of dual-powering four-stroke self-ignited engine, using alternative gaseous fuel, applied to air inlet system, charcteristic of alternative gaseous fuel applied in gaseous or liquid state to each cylinder's inlet duct independently, in doses identical or various for any individual cylinder, via individual injectors (10a, 10b, 10c...) driven by microprocessor programmable controller (2) preparing alternative gaseous fuel dose individually for given work cycle of given cylinder in given engine, in the way ensuring controllable alternative gaseous fuel and inducted air stream stratifying ratio, and knocking combustion detection (17) caused by alternative gaseous fuel overdosing is being made for each work cycle of each cylinder of given engine separately, and optimal energy value of both fuels summary dose for given work cycle of given engine's each cylinder is being stated by comparative analysis of crankshaft rotational speed unevenness in the ambit of angular crankshaft position ranges related to combustion process in particular cylinders of given engine, and the dose of basic diesel fuel is being reduced identically for all cylinders, or in various degrees for each cylinder, to keep unchanged or increased a combustion duration time of each cylinder, falling on each of his work cycles, comparing to identical conditions with basic powering only.
