1. a cylinder displacement measuring device, for octane number machine or diesel cetane-number machine, is characterized in that,Comprise laser displacement sensor (1), laser pick-off loop (2), Laser emission loop (4), laser reflection piece (3), display (5), Acquisition Circuit (6);

  • In described laser displacement sensor (1) and described laser reflection piece (3), one of them is arranged on the body of octane number machine or diesel cetane-number machine, and another is arranged on the cylinder of octane number machine or diesel cetane-number machine;

    Described display (5) is positioned on the panel of octane number machine or diesel cetane-number machine;

    Described Acquisition Circuit (6) is arranged in the cabinet of octane number machine or diesel cetane-number machine;

    Laser is launched in described Laser emission loop (4), in the process that described laser reflection piece (3) moves up and down with cylinder, the laser of launching is reflected, forming described laser pick-off loop (2) beats on described laser displacement sensor (1), by described laser displacement sensor (1), capture shift length, and by described Acquisition Circuit (6), displacement signal is converted to digital quantity and shows by described display (5).
