Will It Start ? - Spark Plugs With Ground Electrodes Removed
HTML-код
- Опубликовано: 13 фев 2023
- Will an engine start and run with the spark plug ground electrodes removed. Watch and find out !. WARNING: This test is for experimental purposes only. I am not recommending that you try this on your own vehicle as it may cause serious or irreparable damage to your engine or catalytic converter. NOTE: Gapping the spark plugs to your engine’s specifications is important. If the gap is incorrectly set, it can lead to engine issues. The engine may experience lack of power, misfiring, spark plug fouling, increased spark plug wear and poor fuel economy. Too small of a gap may give too weak of a spark to complete the combustion process within the engine but too wide of a gap can lead to the spark plug not firing correctly, causing misfires at higher speeds.

A ground electrode interrupts the flow of gas, causing an occasional miss. The spark in a surface gap has a longer distance to travel, but it's conductivity
is enhanced, carried, actually, by the surrounding electromagnetic field, creating a plasma effect. It is very efficient, best used in very high compression engines.
Anyone else immediately googled for a spark plug tester? 😂
This explains why I only had a misfire at lower speeds when one of my plugs was broken like this. If all 4 are broken like yours it’ll run smoother than mine did since all of yours are under performing. Your mileage would be crap though. When only one is broken and the others are good that broken one definitely stands out.
Visually vry very instructivvr never thought of seeing one,. Which electrode is more important than zothe?
With my micra k12 sitting at 169'000 miles Im pleased to see the K12 work some miracles here for you as well...
God only knows why but it explains the Guide of ..." No need to set the plug gaps new ,or at any time in servicing "
Yeah they seem to be bullet-proof little engines !
Thanks for your experiment! Would you please explain the gap size related to the car types or spark plug types?
I should imagine that the larger spark plug gap will cause issues under heavy engine load when the fuel mixture is much denser. The engine is doing well though with the huge distance the spark has to jump. The ignition coils are more than up to the job!
They call these surface gap/discharge spark plugs. Was thinking about doing this for a custom gap. Most surface discharge plugs have a gap of 0.010" - 0.020"
Presisly today I brought NGK spark plugs LFR5AGP for my Micra 2006.
Pengujian busi yang bagus.
Thanks !
thank you
You're welcome !
Could you share please rpm with electrode to compare performance
All 3 plugs were run at a max of 6000 pulses per minute on the tester
It's a nissan, of course it'll run. 😄
lol :)
THIS just happened in a car I JUST purchased while checking the spark plugs yesterday for a fresh maintenance start. Plug in Cylinder 4 was LOOSE when taking coil off and there was lots of black soot/carbon build up on intake head walls. I unscrew plug fully & there’s NOT “L” TIP, just center nipple! I made a “straw funnel” & attached it to my vaccum and put it in the cylinder to suck up any debris. I’m not sure if plug tip is in there or not how even how long it’s been snapped off, The Engine seems to run fine. There are NO CEL’s. I ordered a endoscope off Amazon so I can see what’s in the cylinder for sure. What’s the chances the spark plug tip went out the exhaust valve and into the car converter?! 😅 wishful thinking, I know….. 😢😢
Did you check the other 3 plugs ?
@@screwsnutsandbolts yes. They were snug tight and looked normal upon inspection. I ordered a endoscope and I can see the fcuking tiny piece against the cylinder wall. I’m gonna attach a rubber hose to the end of my vaccum to see if I can suck it up. I really don’t wanna take the top end apart for this one piece. I think we’ll eventually fish it out, it’s just gonna take some clever McGiver type ish… but the cylinder doesn’t appear to be nearly has scratched at the chainsaw in this video, thank god
Good luck, hope you can fish it out of there !
Endoscope for the win! Spotted piece in Toyota cylinder, wasn’t able to fish it out with magnet OR using latex tubing attached to vacuum. Wound up leaving other 3 plugs/coils attached and starting engine with problem cylinder open (no plug/coil attached) for like 10 seconds. Pressure blew it out the top of engine!
Endoscope showed that My focus did NOT have spark plug Debris in the cylinder so it must have went out the exhaust valve… endoscope showed cylider in very good condition too!
Both cars back on the road with no misfire/running issues 🎉
How long is the ratchet extension?
10 inches
C 👀 L t o s e e . . . 😁👍
Thanks for watching !
Did you try to drive it?
No the car isn't roadworthy at the moment :)
not ideal
