Abstract

DC60 (18/04/55) The purpose is to identify the upper dead center of the compression stroke by using a normally provided sensor. in the engine Rhythm classifier that includes 12 ignition pulse generators for signal output. Pulse generator at a preset position near the top dead center of the engine. The device is provided with a path which measures the angular speed of the crank of each section by Divide one engine cycle into four equal-angled sections. are classified in response to The pulse generator signal that the variation of the angular velocity of the crank can be detected for Do each of the four sections during a cycle correspond to a predefined pattern? When the angular velocity change pattern of the crankcase of the four sections corresponds to the pattern pre-defined The moment of output of the pulse generator is set to top dead center of engine compression stroke can represent the angular velocity of the crank Four sections are determined by the rotation time of the crankshaft of each section.
