Petteroids / A Petteroid that fires once.
« on: July 21, 2007, 08:00:52 AM »
Hello everyone...

Nicely and smoothly, after a 2 minute no-load period, I turned off my 10/1 petteroid connected to a generator head after a smooth and nice 1.5 hours run. 8 hours later it is behaving like this: crank turned normaly with the normal "ringing" sound of fuel at the injector until I release the valve when it fires once, and only once, before "ringing" disappears and so there is no more firing. This is reproducible i.e. when I repeat the procedure, ringing is normally high again, and it remains high no matter how long I continue no-compression crancking, but when compression occurs at the release of the valve lever, it always, and I stress: "always" fires but one firing and the sound dies again and everything decelerates to a dead halt. To be accurate, before the dead halt the engine managed to fire another single time. I tried to exhaustion. Air is well aspirated and this is rechecked two times. I havent checked the return outlet behavior yet, and I havent tried to examine the injector yet althoug I've just removed carbon "micro-chimnies" that formed around the nozzle openings the same morning with fantastic results on smoothness and dark smoke. My petteroid is- and forgive me because I know it is wrong- is on pure kerosene for about 30 - 40 hours now, nice and smooth.

I am waiting to hear from the experienced coz I'm the newbie here.

I'll soon post what I'll find upon checking the return output of the injector and probably the injection at the nozzle.

Regards
