@Doktoreq 3 жыл бұрын

@Alfred Wedmore The timer will start at wrong pulse when the first pulse is out, engine rotate wrong way or you have so much noise in the system that it wouldn't work anyway. In either case you're looking at more serious problems. And why the hell do you need a microcontroller with a timer do count pulses - there are just two pulses: falling edge, raising edge, falling edge and raising edge again. The simple timer will do this without noticeable delay (somewhere in ns range) and doesn't require any code. The microcontroller requires writing code which is strictly deterministic - the output have to have precise delay or all your engine timing gets out of whack. Also why are you talking about camshaft sensor? Is this some "fancy" 4 cylinder engine with full sequential injection that requires that?

@Doktoreq 3 жыл бұрын

@Alfred Wedmore For my purposes I would probably use simple delay timer (555 circuit most likely) triggered of cranking signal to delay enabling of 4017 counter by some ms in case the engine stopped with HALL sensor between two magnetic spots. Tie 1st output of 4017 to the ECU input, tie 2nd output to the reset pin and IC triggers on 1st pulse resets on second. I don't talk about noise in the system cause if there is enough noise to trip counter IC it would most likely fool ECU presented in the video without counter IC. Also I know that sticking magnet on camshaft is best solution but I'm not considering it because it's not a solution used on this channel. It was stated in episode 21 video around 8:25 mark (kzfaq.info/get/bejne/Z7pogMxkzJ2XaGQ.html) the collar with a magnet was placed on a CRANKSHAFT. Either ECU have some way of sorting itself out (via intake pulse or something) or have problems running because it will try to squirt fuel and fire every 360 degrees instead required 720. It will try to fire on the intake stroke and squirt fuel at the combustion stroke so I suspect running rich and firing into intake.

the ease and familiarity with which you described how the fuel injection system works was a hint and a half that you were in the electronics field. when you said you don't know how people work on electronics without an oscilloscope was the clincher. most people don't even know what an oscilloscope is, let alone how to use one. then not only did you realize the system wouldn't work as you planned without having to try it first, but came up with an elegant solution to the problem. it didn't take sherlock holmes to point out they are all signs of a highly skilled electrical engineer. obviously, building complicated go karts is just a hobby to pass the time when you're not solving some problem that would have the rest of us sitting in a corner hugging our knees and rocking back and forth with mental overload.

@TEDodd 3 жыл бұрын

As long as the collar stays put you can tweak the timing in the code. If the code says 22.5 and it's actually 21.75 doesn't really matter as long as the offset stays consistent in the table. Much Luke manually tuning a distributor, what matters is how it runs, nor the exact placement. One engine might like more or less advance so you tune to the motor not some calculation. The calculation just give you a good starting point. Same here. The placement of the collar/trigger get yiy a starting point. The you tweak for the engine/application.

Considering the mass of the metal ring you are mounting the neodymium magnet in plus the sensitivity of the Hall effect sensor, I don't think heating will be a problem. There are plenty of other things that could go wrong long before that would have any impact. Engines that are pushed beyond their maximum intended output don't last that long anyway. So, It's not worth worrying about.

@Revoku 3 жыл бұрын

the magnet you used will be fine, I made a hall effect sensor circuit and triggering setup for an old 3 cylinder engine, it ran for years, the temp the crank gets to on the outside of the your engine is below max operating temp typically for the magnet(76-83C), and even if it gets above, the sensor you are using is so sensitive that even in a heat weakened state the magnet would do the job for years regardless. the piece of old garbage 3 cylinder I did up has the magnets in a much worse heat exposed area than you have them, and they have been running/working well for 10 years(and my sensor setup is home made garbage made from a TO-92 package sensor), and I'm betting the quality of my cheap magnets is alot lower than what's cheaply brought today.

@TzOk 3 жыл бұрын

Thank you for this episode, now the problem with a double trigger is clear. On the first video, there was an impression, that you are stating that it triggers twice, because it turns on, on the both edges of the magnet, which is not the case. The real problem was, that it turns off again, when it is far from the magnet, which was not shown before, so the pattern looked something like this: 000101000.

I don't know much about electronics, but when I look at that with the flywheel setup I feel like it would work if you made the signal from the flywheel turn an electronic switch on and off and just increased the angle from top dead center a little more on the configuration program. Then the signal goes from on pulse, off pulse, on pulse, to signal on..... signal off. Just a suggestion.

Also if you reach it's curie temp, you're going to have bigger issues with the engine already.

I wonder if insulating the ring from the axis would prevent it from running hot, by running a small plastic sleeve between the ring and the axis. The ring would cool through friction with the air, and the magnet will surely be a few degrees colder. Besides, the plastic sleeve will probably allow for a much better grip (I think).

Made perfect sense already last time. My problem is, that I´m afraid, that your new, small flywheel (with thus lower resolution) will trigger the sensor for 2/360ths-3/360ths instead of just 1/360th of a flywheel-revolution. Maybe you´ll have to space the sensor further of the small flywheel, so to get a shorter lasting triggering signal (higher resolution), even if then that signal gets a bit weaker.. But that´s just my thoughts, and I have no clue about such stuff... After all, the old, big flywheel had a gigantic magnet (so, also low resolution/precision ;-), while the new, small one has a tiny, matching magnet, so, just my thoughts...

@robotcantina8957 3 жыл бұрын

The ECU operates so fast that the signal we are getting is plenty. For the ECU it seems like eternity between crank signals. Keep in mind the crank trigger doesn't directly fire the ignition. All the calculations including dwell are based on data collected on the previous revolution.

It could have been solved using some inverters and an AND gate. However, as you said, it's not something your Average Joe would understand. Furthermore, your approach is far more headache free, considering that there's fewer stuff to go wrong. Getting engines to run without electronics is a task of itself, i'd be wary of using a pulse generator on the igniton timing. Even a slightest issue could make your car run bad and could take weeks to find.
