Luminosity probe for diesel engine timing apparatus

摘要: The probe includes a tubular housing having first portion and second portion. is adapted to be mounted in place of the glow plug selected engine cylinder. A light pipe within directs from combustion zone phototransistor front has reduced size aperture defined by an internal shoulder against which seated. rear carries resilient sealing means deformed when telescoped thereon so as provide detachable, frictional, light-tight thermally insulated connection therebetween. convert passing through into electrical signals. cable these signals processing equipment. base resistor located between cable. part that projects short with respect fits engine. projecting wrench-engaging bosses.
