The present invention relates to the synchronisation of an internal combustion four-stroke engine (1) during engine start up. The engine (1) comprises a number of cylinders (11-14) with pistons (I-IV) linked to a crankshaft (36), means (32,33,34) to provide a series of pulses (30) on each cycle of the engine (1), and an engine management system (10) that includes: a memory (44); means (10,29,32) to determine the engine cycle after the engine (1) is cranked; and means (9) to count thereafter the series of pulses (30) until the engine comes to a stop in order to determine the engine cycle of the engine (1) when subsequently stopped so that data representative of the engine cycle may be stored in the memory (44). According to one aspect of the invention, the means (10,29,32) to determine the engine cycle after the engine (1) is cranked is a means to determine the engine cycle during running of the engine. According to another aspect of the invention, the means (10,29,32) to determine the engine cycle after the engine is cranked includes a memory (44) that stores data representative of the engine cycle of the engine before the engine was cranked. <IMAGE> |
