Figure 2
Schematic illustration of the detector triggering set-up. A pulse is triggered every 360°, by the proximity sensor mounted on the rotating shaft mounted on a 1:1 ratio to the crankshaft. The pulse is fed to the TTL pulse generator and the process monitoring oscilloscope. The parameters, such as pulse delay (P.D.) that controls the angular position we are hitting the con-rod according to the r.p.m., i.e. phase, and the pulse width (P.W.) which controls the exposure time, i.e. the time that the shutter of the detector remains open on every cycle, are adjusted. The overall time cycle of the emitted pulse is set just under the duration of two overall crankshaft revolutions to ensure triggering on the same stroke each time.
