TH61628A - Engine timing classification device - Google Patents

Abstract

DC60 (18/04/55) The purpose is to classify the upper dead center of compression strokes using a normally provided sensor. In the engine A stroke classification device that includes a 12 ignition pulse generator for signal output. At a predetermined position near the upper dead center of the engine, a device is provided with a trajectory that measures the angular velocity of each section of the crankcase by Divide one engine cycle into four equal angles. Are classified by responding to Signal the pulse generator that the detected angular speed change pattern for Do each of the four sections during a cycle coincide with a predefined pattern? When the variation of the crank angular velocity of the quarter is consistent with the pattern Preset The moment of output of the pulse generator is set at Upper dead center of engine compression stroke Can represent the crank angular velocity of The four sections were obtained by the crankshaft rotation time of each section. The purpose is to identify the upper dead center of compression strokes using the normally provided receptors. In the engine The rhythm classification device consists of Ignition pulse generator 12 for signal output. At a predetermined position near the upper dead center of the engine, a device is provided with a trajectory that measures the angular velocity of each section of the crankcase by Divide one engine cycle into four equal angles. Are classified by responding to Signal the pulse generator that the detected angular speed change pattern for Do each of the four sections during a cycle match a predetermined pattern? When the variation of the crank angular velocity of the quarter is consistent with the pattern Preset The moment of output of the pulse generator is set at Upper dead center of engine compression stroke Can represent the crank angular velocity of The four sections were obtained by the crankshaft rotation time of each section.
