Method for measuring output variation of internal combustion engine

Abstract

Abstract PURPOSE:To measure output variation always precisely by correcting with a number of revolution a periodical and pulsating change appearing in accompany with every explosion stroke of a cylinder such as the number of revolution of an engine, torque and pressure in a cylinder. CONSTITUTION:An angle signal plate 3 is fitted to a pulley 2 positioned on the leading end of a crank shaft 1 of an engine E. An angle signal sensor 4 is provided oppositely to the signal plate 3. A cylinder discriminating sensor 6 is built in a distributor 5. The outputs of the angle signal sensor 4 and the cylinder discriminating sensor 6 are inputted to an arithmetic unit 7. The arithmetic unit 7 detects the pulsating change of the number of revolution appearing in the explosion process of the engine E and the detected change of the number of revolution is corrected by the number of revolution to measure the variation of the output.
