Abstract
A multi-cylinder internal combustion engine is described in which each cylinder is capable of operating within a predetermined auto-ignition torque/speed range. Selected cylinders are disabled when the average cylinder torque lies below the auto-ignition torque/speed range so as to raise the torque of the remaining power producing cylinders and enable them to continue to operate within the auto-ignition torque/speed range.
Claims7
A method for controlling a multi-cylinder internal combustion engine comprising disabling selected cylinders when an average cylinder torque lies below an auto-ignition torque/speed range so as to raise an output torque of the remaining active cylinders and enable them to continue to operate within said auto-ignition torque/speed range.
A method for controlling a multi-cylinder internal combustion engine comprising:
- providing an indication that an average cylinder torque is below a predetermined threshold;
- in response to said indication, disabling a predetermined number of cylinders;
- and
- increasing an amount of fuel and air injection into remaining active cylinders, wherein said increase enables said remaining active cylinders to operate within an auto-ignition torque/speed range.
