Optimum Rate Of Voltage Rise for Minimum Energy Loss In Ignition Systems

THE development of engines with higher compression ratios and those having valves in the head has meant that the minimum performance requirements of present-day distributor and coil type ignition systems are being approached.

The authors of this paper have closely examined the ignition system as a whole to determine if these new demands can be met without appreciably increasing the primary current.

The authors suggest that, if the reserve energy of ignition coils could be used more effectively, we could reduce its value and use the excess energy to charge the secondary circuit to a higher voltage without affecting total reliability.
