There’s nothing quite like the feeling of getting into your car, turning the key (or […] ...

As long as there have been internal combustion engines, there has been a need for an ignition system to ignite the air and fuel mixture in the cylinders. From the earliest days of automotive ignitions ...

No Ford engine project is complete without a properly functioning ignition system. This system has the important job of delivering the spark to the required cylinder at precisely the right time. Any ...

Ignition coils sit at the center of every gasoline engine’s spark, yet they usually stay invisible until something goes wrong. When a coil starts to fail, the symptoms can look like fuel problems, ...

Ignition coils play a crucial role in a vehicle’s ignition system. They serve to convert the battery’s low voltage into the high voltage necessary to fire the spark plugs. If there’s any malfunction ...

Around 1975, General Motors made a significant advancement in stock passenger ignition technology: the High Energy Ignition (HEI). One of its major features was installation simplicity. The coil was ...

Traditional automotive ignition systems can be either inductive discharge or capacitive discharge. Traditionally, old-school stock engines had inductive discharge systems that rely on the coil to do ...

Automotive ignitions systems have seen many transitions over the years. Historically, the designs have matured from a magneto to today’s coil-over-spark plug designs. The progression follows the ...

F. R. HAIGH has recently compared the relative advantages of magneto and coil ignition used for generating the explosions which occur in motor-car engines (Students' Quart. J. Inst. Elec. Eng., Dec.).

This ignition coil driver is a HOT one! From my recollection, it delivers a nastier spark than the legendary Ford Model T ignition coil. The circuit uses an inverted 555 oscillator that is coupled to ...
