Abstract
In this paper a novel multi-purpose flywheel (MPF) is introduced. This MPF has all the functions as a conventional flywheel, but it can function as a crankshaft wheel to detect crankshaft angular position, speed, and acceleration. Therefore, this MPF can eliminate the conventional crankshaft wheel. Since the flywheel is normally installed in the rear of an engine, the MPF provides more reliable engine acceleration information than a damper-based crankshaft wheel that is normally located at the front of an engine. Thus the new MPF reduces part counts, saves space, reduces cost, and especially benefits misfire detection and other applications in engine control and diagnoses. The principle, function, design, and manufacture of the MPF are presented in this paper. Bench test and vehicle test results are also presented.
