Measuring probe for ignition circuit.

摘要

Measuring probe equipping a high-tension electrical ignition circuit of an internal-combustion engine, in particular for motor vehicles which include means for measuring the high tension and the current at a point in the secondary circuit, the said means consisting of a purely resistive circuit (R1, R2; R'1, R'2; R3) which can be located in a cylinder-head spark-plug chamber (well). <IMAGE>
