Engine speed control system
First Claim
1. A method of controlling the engine speed of an internal combustion engine, the method providing the steps of determining the speed of the engine at a given time, determining the change in the speed of the engine from a previous determination of the engine speed, and using the values for engine speed and change in engine speed to determine whether a future event should be a combustion event or a non-combustion event wherein the engine has a direct injection system and a fuel event is not scheduled when it is determined that a non-combustion event is required.

- 1. A method of controlling the engine speed of an internal combustion engine, the method providing the steps of determining the speed of the engine at a given time, determining the change in the speed of the engine from a previous determination of the engine speed, and using the values for engine speed and change in engine speed to determine whether a future event should be a combustion event or a non-combustion event wherein the engine has a direct injection system and a fuel event is not scheduled when it is determined that a non-combustion event is required.
- 24. A control system for an internal combustion engine in which current engine speed and the change in engine speed from a previous determination are taken into account when determining whether a future event should be a combustion event or a non-combustion event.
- 28. A method of controlling the rotational speed of an internal combustion engine, the method including the steps of determining whether the engine speed is likely to exceed a predetermined threshold engine speed, and implementing a pattern of combustion events and non-combustion events in at least one engine cylinder in order to modify the effective fueling level to the engine cylinders so as to control the engine speed in relation to the threshold engine speed.
