  • Torsion lock encoder device for internal combustion engine
    Patent number: 8100104
    Abstract: An internal combustion engine crankshaft assembly includes a crankshaft having an output device, such as a flywheel or crankshaft damper, fastened to the crankshaft. An electronic engine control device is positioned between the crankshaft and the output device. The electronic engine control device includes a generally planar base which contacts both the output device and the crankshaft. The planar base is coated with a pressure-responsive friction-promoting material which causes the output device to be torsionally locked with respect to the crankshaft.
