Abstract
Disclosed is a method of operation of a marine engine comprising sensing an operator demand for a gear-shift and, in response to the sensing of said operator demand, varying the engine torque profile to enable said gear-shift. Typically, the engine torque profile is required to be varied to overcome forces resistive to gear-shift.
Claims31
A method of operation of an internal combustion engine comprising sensing an operator demand for a gear-shift and, in response to the sensing of said operator demand, varying the engine torque profile while maintaining a mean engine output torque to thereby enable said gear-shift to be effected.
A control system for an internal combustion engine comprising means for sensing operator demand for a gear-shift, and means for varying the torque profile of said engine while maintaining the mean engine output torque to overcome forces resistive to gear-shift in response to sensing of said operator demand for a gear-shift.
A method of operation of an internal combustion engine comprising sensing an operator demand for a gear-shift and in response to said sensed operator demand, varying the engine torque profile while maintaining a mean engine speed to thereby enable said gear-shift to be effected.
A method of operation of an internal combustion engine comprising sensing an operator demand for a gear-shift and in response to said sensed operator demand, varying the engine torque profile such that said profile is non-periodic.
