Ignition Definition and 66 Threads

My friend and I are trying to build a very basic to get a spark plug to fire. Right now we have a plug, and Ignition coil that outputs 20 kV. The Ignition coil says on it 12 V and was bought at an auto parts store so I am assuming its an ignition coil for a car. What kind of battery should we...

Im trying to find out the difference. It seems that an ignition coil converts the cars battery voltage from 12V to several thousand volts; whereas, a magneto creates several thousand volts without any input from the aircrafts battery.

Hey guys, Just trying to understand this piece of information I have been given. It is for a compression ignition engine. I can see where they get the 115.954 kmol/kmol fuel and 120.204 kmol/kmol fuel from but don't understand how to change the units 0.7027 kmol/kg fuel and 0.7285 kmol/kg...

Hi all.. I have been working on a project which involves the measurement of ignition delay of fuel droplets using optical sensors of the beam-break type. What my project supervisor has asked me to do is to fabricate an apparatus in which such measurements could be made. The basic principle...

Dear friends, I am building a CDI system to ignite fuel mixtures in a pressure chamber for flame speed measurements. I need a capacitor of about 5 nF, but it should hold up to 10 kV. Any suggestions on where I can get those. I also need a diode (rectifier) for 10 kV. Also I need high...

I want to use a 50-pin cable to ignite e-matches connected to fireworks. The e-matches require about 1 Amp to ignite. The individual conducting wires in the cable are obviously very thin, and thus can't conduct a continuous 1 Amp current. My question though is this: can the very thin conducting...

I am going to try to build an electrical ignition system similar to an Estes rocket ignition system. The idea is simple enough, just run a bunch of current through a wire until it heats up, but it gets harder if you want to do this from a safe distance away from what you are igniting or you...

The genesis of this design as described to me is a single 980 nm Pump Diode which is fiber-optically split into 192 fiber-optical 'beam lines' using a Fiber Bragg Grating. The 'laser amplifiers' then amplifies this pulse more than 1 million times which is propagated to the target chamber. The...

If someday complete direct injection spark ignition with gasoline engine with Otto cycle is achieved so that very high pressure ratios are possible, what would be the impact on the automotive industry?

I was wondering, anyone who know about cars and such, is it hard on your transmission to shift it while you're moving? I do it all the time, but my don't-abuse-transmission-crazy dad yells at me and says it is, but I've seen it done before many times, and they keep right on going. And I mean...

Does gasoline have a higher ignition temperature then ethanol? (all other things being equal like pressure) Also does a higher ignition temperature mean that it will produce more energy upon combustion? Thanks in advance.

Hey people, been getting very annoyed for the past few hours over this one been looking through all my textbooks and all over the net but can't find a decent explanation of dwell time. Here's my question, Explain dwell time in the context of electronic ignition systems (non-contact breaker...

Voltage pulse from ignition coil ?? Hi, Does anyone know the voltage of the pulse from a typical ignition coil? thanks. tyler

I have been reading up on some theoretical ideas for supernovai etc..etc It is interesting that there may be some correllation between Blackholes and AGN, and consequently Stars going Supernova. Does anyone know if what I am going to state has been looked into? It seems probable that...

Out of curiosity, can you produce a self perpetuating nuclear fusion chain reaction - in effect a new sun - by dropping a nuclear bomb deep into the atmosphere of a hydrogen rich gas giant? If a powerful enough weapon was fired on a non-hydrogen atmosphere like Earth's, bearing in mind that...
