It is, but more accurate too. Besides diesel engines can also be monitored this way.That seems a lot more complicated than going to a garage and watching the scope for low spark voltages!
As I suggested in one of the other threads you started on this topic, "My suggestion is for you to post a schematic of what you have built. Otherwise, there is no way for anyone to suggest anything sensible."Oh i'm sorry didn't see the comments above, well lemme explain everything. I am using a piezo transducer to detect vibrations produced by a car engine, after that now i also want to detect a faulty cylinder in the same car engine while driving.
It seems that you have started seven different threads all associated with this same subject, and have received over 60 replies, and you are not satisfied. In all of this, you have never provided any evidence of your own efforts. If you really want help, post the schematic of what you have built. Or are you expecting someone here to do all the work?I dont really have the schematic on my laptop but i can explain it to use. the piezo is attached to a 2n700 transistor to amplify it and then the output is connected to a 555 timer for a missed pulse detector that is all i have got for now.
