Claim 3:
4. A method as claimed in claim 3 wherein the values of accelerations are determined from the following formulae

ace=(speed Max(n)−speed Min(n))tint 

where speed Max(n) is the speed maxima following the combustion event n; speed Min(n) is the speed minima prior to the combustion event n; and tint is the time between the maxima and the preceding minima;
and/or

ace=(speed Min(n+1))−speed Max(n))/tint 

where speed Max(n) is the speed maxima following a combustion event n; here speed Min(n+l) is the speed minima immediately after the combustion event n; and tint is the time between the minima or maxima and the preceding maxima or minima respectively.
