Abstract
A water-cooled multi-cylinder engine, includes a control system in which an engine revolution number is reduced to a level less than a restriction revolution number on the basis of at least one condition of misfire and fuel stop for all the cylinders of the engine, at a time of an occurrence of an overheat, so as to restrict an increasing of a temperature of the engine. In a case when the engine revolution number is less than the restriction revolution number after the overheat occurs, or the engine revolution number is lowered to be less than the restriction revolution number on the basis of the revolution number restriction control, a specific cylinder is controlled to be stopped by at least one of misfire and fuel stop.

A control system of an engine of a water-cooled multi-cylinder structure, in which an engine revolution number is reduced to a level less than a restriction revolution number on the basis of at least one condition of revolution number restriction controls including misfire and fuel stop for all cylinders of the engine, at a time of an occurrence of an overheat of the engine, so as to restrict an increasing of a temperature of the engine, wherein in a case when the engine revolution number is less than the restriction revolution number after the overheat occurs, or the engine revolution number is lowered to be less than the restriction revolution number on the basis of the revolution number restriction control after the overheat occurs, a specific cylinder is controlled to be stopped by means of at least one of the misfire and the fuel stop.
A control system of an engine of a water-cooled multi-cylinder structure for controlling a revolution number of the engine, comprising:
- means for detecting an occurrence of an overheat of an engine;
- means for monitoring and detecting an engine revolution number;
- means for discriminating whether the detected engine revolution number exceeds or not a restriction revolution number after occurrence of the overheat;
- and
- means for performing an operation stop control to a specific cylinder by means of at least one condition of revolution number restriction controls including misfire and fuel stop to thereby reduce the engine revolution number.
A method of controlling an engine of a water-cooled multi-cylinder structure for controlling a revolution number of the engine, comprising the steps of:
- detecting an occurrence of an overheat of an engine;
- monitoring and detecting an engine revolution number;
- discriminating whether the detected engine revolution number exceeds or not a restriction revolution number after occurrence of the overheat;
- and
- performing an operation stop control to a specific cylinder by means of at least one condition of revolution number restriction controls including misfire and fuel stop to thereby reduce the engine revolution number.
