Abstract (en)
[origin: WO2017042423A1] Invention relates to method of determining an offset (38) relating to crank angle measurement in connection with a cylinder (12) of an internal combustion pis- ton engine (10), in which method the engine (10) is rotated and it is refrained from fuel combustion in the cylinder, a reference value for the indicated mean effective pressure is determined, an integral value of indicated mean effective pressure in the cylinder is determined over a range of crank angle during all of the gas exchange valves of the cylinder are maintained closed, and wherein a dead center position of the piston is located with the range, a crank angle position offset value is determined based on the determined integral value of indicated mean effective pressure and the reference value for the indicated mean effective pressure.
