Апстракт:
Essence of multiprocessing operation principle of an engine is to achieve Otto and Diesel working process in the same cylinder, depending on operating regime and using two different types of fuels. Thus, this engine has two fuel supply systems and an ignition system. The main problem of the ignition system is reliability of a spark plug during longer operation of the engine in Diesel mode. Due to potential forming of electrically conductive deposit on a ceramic spark plug isolator, instead of using classical ignition system (one spark per cycle), multy-sparks producer type of the ignition system is used that is able to obtain continuous, arbitrary long electric discharge between the spark plug electrodes. Possible occurrence of electrically conductive deposit leads to establishing of surface electric arc and momentary burning, which enables self-cleaning of the spark plug. Description of proposed ignition system and comparison of its electric characteristics with standard BOSCH MP 3.1 ignition system in laboratory conditions are presented in the paper. Comparative results of engine tests of these two ignition systems also are given in the paper.
