Abstract:
A control system for an internal combustion engine comprising:a reverse command generating means generating a reverse command for switching a running direction of a running equipment driven by a two cycle internal combustion engine, a reverse processing means executing a reverse process necessary for reversing a rotative direction of the internal combustion engine in response to the reverse command that the reverse command generating means generates, a rotative direction detection means generating rotation detection signals of which states are different at each time when the internal combustion engine is forwardly and reversely rotated and detecting the rotative direction of the internal combustion engine from a state of the rotation detection signal, a reverse failure determining means determining the failure of reversing of the internal combustion engine when the rotative direction detected by the rotative direction detection means does not correspond to the rotative direction commanded by the reverse command, and an internal combustion engine drive control means controlling the internal combustion engine so that running of the running equipment is prevented when the failure of reversing of the rotative direction is determined by the reverse failure determining means.
