The history of the capacitor discharge ignition system can be traced back to the 1890's when it is believed that Nikola Tesla was the first to propose such an ignition system. In United States patent #609250 first filed February 17, 1897, Tesla writes 'Any suitable moving portion of the apparatus is caused to mechanically control the charging of a condenser and its discharge through a circuit in inductive relation to a secondary circuit leading to the terminals between which the discharge is to occur, so that at the desired intervals the condenser may be discharged though its circuit and induce in the other circuit a current of high potential which produces the desired spark or discharge.' | The history of the capacitor discharge ignition system can be traced back to the 1890's when it is believed that Nikola Tesla was the first to propose such an ignition system.

The patent also describes very generally with a drawing, a mechanical means to accomplish this. In the late 1940s an attempt to make one using mechanical means to trigger the capacitor's discharge was tried. It used extra contact switches in addition to the usual points, but suffered from timing problems and was unreliable. The quest for an electronic means of producing a CD ignition began in earnest during the 1950s. In the mid 1950s, the Engineering Research Institute of the University of Michigan in cooperation with Chrysler Corporation in the United States worked to find a method to produce a viable unit. | The patent also describes very generally with a drawing, a mechanical means to accomplish this.
