PicoScope 7 Automotive
Available for Windows, Mac, and Linux, the next evolution of our diagnostic scope software is now available.
But wouldn't that mean that much of the energy has already been lost from the coil before the rotor arm lines up with the particular plug lead?Autonerdz wrote:This is because the plug wire only shows the activity after the rotor. Much of the secondary activity you accustomed to seeing takes place before the rotor, including the coil oscillations.
Not sure I understand the question. The energy is released once the secondary current begins to flow. This does not happen until the gap requiring the highest KV is overcome and the spark is lit. There is no activity on the plug wire until the current bridges the rotor gap. Then the activity stops when the current stops. The residual energy oscillations remain upstream from the rotor and are not seen on the plug wire.But wouldn't that mean that much of the energy has already been lost from the coil before the rotor arm lines up with the particular plug lead?
Sorry - had a blonde moment there, I had overlooked the fact the rotor arm isn't actually connected to the plug wire, as it passes by. The moment I read your reply it all came back to me.Autonerdz wrote:Not sure I understand the question. The energy is released once the secondary current begins to flow.
