摘要
The invention relates to a method for improving the starting ability of an internal combustion engine during difficult engine starting conditions.;Since lower than normal engine starting speeds are the result of external circumstances, it is essential that the spark plugs are free from deposits and in their best condition, so as not to hinder an engine start.;The method and arrangement solves this problem by burning-off any deposits present on the spark plugs (11-14) during the engine start attempt, when difficult engine starting conditions are detected. During the engine start attempt a comparison circuit (5) ascertains whether or not one or more detected engine parameters have a lower value than in normal engine starting conditions. The comparison circuit (5) sends a signal to the control unit (3) controlling the ignition system (2), so that the control unit (3) will initiate the generation of a plurality of sparks instead of a single spark at ignition time points. The resultant spark shower then burns-off any deposits that are present.
