Abstract (en)

[origin: EP0258694A2] A method of accurately determining the theta profile of an internal combustion engine measures cylinder time intervals under a rapid deceleration condition, finds the series of time intervals having the highest deceleration and assuming a constant deceleration during the series of time intervals, calculates the theta for each cylinder.
