    摘要: A method for accelerating the rotational speed of a crankshaft of an internal combustion engine having a plurality of cylinders each having a spark plug wherein a predetermined amount of delivered fuel is to be combusted at a firing time within each of the plurality of cylinders with each rotation of the camshaft or crankshaft based on an acceleration input made by an operator includes the step of receiving the accelerating input, measuring the rotational speed of the crankshaft, defining an expected engine speed based on the acceleration input, calculating a speed error as the rotational speed of the crankshaft less the expected engine speed, calculating engine acceleration and adjusting the predetermined amount of fuel delivered to be combusted in each of the plurality of cylinders to reduce the speed error when the speed error is a function of the instantaneous engine speed. The preferred embodiment is implemented using fuzzy logic.
