Abstract
1,159,473. Testing I. C. engine timing. ROBERT BOSCH G.m.b.H. July 27, 1966 [Aug. 17, 1965], No. 33771/66. Heading G1U. An apparatus for testing the timing of an I. C. engine consists of a detector transformer 9 which triggers a pulse generator 12 on the occurance of an ignition spark, the generator having an output pulse whose width is variable, the trailing edge of the output pulse being used to trigger a discharge lamp 17 which is used to stroboscopically illuminate reference marks on the distributor shaft. All the circuit elements except the transformer 9 are enclosed in a pistol shaped housing 2 which may be held in the hand. The light beam from the lamp is directed through an aperture at the front of the pistol, and the pulse with indicator 5 and pulse width adjustment knob 6 are at the back, facing the operator. In the circuit contained in the pistol, the variable width pulse is passed via a differentiating circuit 14, which differentiates only the negative going back edge, to the base of a transistor 27. The output from this triggers a thyristor 30, which pulses the transformer 31 to feed the trigger electrode of the lamp 17. This is supplied from a D.C. transformer 16 and produces a brief flash.
