1. A method of determining the acceleration of a crankshaft of an internal combustion engine comprising one or more cylinders, with respect to each combustion event, n, among a plurality of combustion events, comprising:
a) providing a signal indicative of crankshaft speed, said signal comprising a series of minima and maxima speeds with respect to each successive combustion event;
b) determining the acceleration of the crankshaft of the internal combustion engine with respect to each combustion event, n, among the plurality of combustion events, based on: an initial speed value of a minima, Min_(n) just before the combustion event, n, and a subsequent speed value of a maximum, Max (n) immediately subsequent to the combustion event, n, as well as a speed of a minima for a subsequent combustion event, Min (n+1).
