Abstract [en]

Direct measurements of the pressure inside the engine have a number of limitations that makes the method expensive and only good for laboratory measurements. Therefore an indirect method to measure the pressure is of main interest. In this study a method based on the crankshaft angular speed fluctuation using neural network has been developed. Two points on the pressure pulse have been reconstructed maximum pressure (Pmax) and start of combustion (SOC). Pmax is predicted with an accuracy of 7.7 MPa and SOC with an accuracy of 1.3 degrees.
