Summary:

Crankshaft torque fluctuation has been theoretically analyzed and possible sources of error have been reviewed in the cases of determining the indicated mean effective pressure (Pmi) from measurement of the flywheel angular-speed fluctuation.The specific objective of this study was to develop a new approach to determine Pmi from the crankshaft torque of a SI engine, and it has successfully proven that using an appropriate data processing for the angular-speed fluctuation, Pmi in low- to medium-speed ranges can be estimated with very high accuracy in terms of 99% or higher coefficient of correlation to the in-cylinder pressure sensor
