Excerpt

Torsion in long or flexible crankshafts can cause deviations between indicated and actual crankshaft angles at a given cylinder, and hence between calculated and actual cylinder volumes for a given crank angle. Kistler Instruments, GE’s Jenbacher product line and the LEC at Graz University of Technology have applied optical, in-cylinder measuring techniques to correct cylinder volume during fired engine operation. The research has led to more accurate combustion analysis, prediction of errors and a method of verifying simulation results. This article is based on a paper presented at the 2014 Torsional Vibration Symposium in Salzburg (Austria). …
