Ignition Systems
[Printer friendly page]

This section will be a repository for information on ignition systems - including but not limited to - distributors, electronic ignition, Pertronix, points, spark plug wires, and spark plugs. Please feel free to send me any information which you think could be helpful. Thanks!

A few bits of information about ignition systems for those who may not know:

Dual Fire (Waste Spark) ignition systems fire both the TDC cylinder and another cylinder not in use, igniting leftover gasses and causing unnecessary loss and vibration
Dual Plug ignition systems typically have a second spark plug in the head at the opposite side of the cylinder. More modern heads are efficient enough that this design gives little gain.
Rev Limiter is a limit imposed in some electrical or mechanical way to prevent the RPM's of the engine from exceeding the some predetermined limit
Single Fire ignition systems fire only the cylinder which is needed at that point to drive the crankshaft
Multi Spark ignition systems typically have two features - a longer spark duration to burn more efficiently and a second spark to burn any leftover flamables in the cylinder
