The engine at stake can be seen at the attached pictures. It's from the magazin 'Model Engineer' and my friend is in the planning phase of making it. I've done the CAD files for him and now he wants to change the engine from it's original glow plug system to spark ignited. As you can see on the rear view, a hall sensor can be attached at the camshaft without destroying the overall look. Imagine this beauty with a distributor...
it will send a charge to each sparkplug only one of which will actually fire
So on the 4-cycle, 4-cylinder engine shown, this means all spark plugs fire together every cycle/90° camshaft rotation? Doesn't this especially leads to problems at the end of the intake/begin of compression?
We thought that maybe it's possible with 4 hall sensors but just one magnet. In the manner that there's just one coil which is triggered by each sensor and somehow the circuit routes the discharge to the corresponding spark plug.
