Abstract
The present invention relates to the synchronization of an internal combustion, four-stroke engine during engine startup. The engine comprises a number of cylinders with pistons linked to a crankshaft, means to provide a series of pulses on each cycle of the engine, and an engine management system that includes: a memory; means to determine the engine cycle after the engine is cranked; and means to count thereafter the series of pulses until the engine comes to a stop in order to determine the engine cycle of the engine when subsequently stopped so that data representative of the engine cycle may be stored in the memory. According to one aspect of the invention, the means to determine the engine cycle after the engine is cranked is a means to determine the engine cycle during running of the engine. According to another aspect of the invention, the means to determine the engine cycle after the engine is cranked includes a memory that stores data representative of the engine cycle of the engine before the engine was cranked.
