my engine melting the spark plugs 2E engine
my engine is 2000cc 2E 8 valve 115hp i have knocking at 4th gear at high rpm i don't know why but it work's after changing the spark plugs from single electrode platnuim to multi electrode copper in the first run at 4th gear at high rpm knock but this time the engine melting the spark plugs i wanna know why i have knocking at 4th gear only at high rpm only and why the engine dont melt the single electrode platnium and melt the multi electrode copper

Re: my engine melting the spark plugs 2E engine
Sounds like an extremely lean mixture and possibly a bad timing setting.

Re: my engine melting the spark plugs 2E engine
Advancing the timing too far without increasing the fuelling can cause a lean mixture and lead to melted plugs.
The platinum plugs don't melt as they are able to handle a far higher temperature than the standard plugs which I assume are BUR6ET that have melted.

Are you using the correct heat range plugs?

Re: my engine melting the spark plugs 2E engine
Common causes of spark-plugs melting:
Heat range of the plugs too hot
Lean mixture
Timing too far advanced
Cooling system not working properly
Oil flow problems in the head leading to heat built-up
Factors above will contribute to excessive heat and/or detonation, can affect the pistons too if not resolved...

Re: my engine melting the spark plugs 2E engine
I would very strongly suggest that you get your car dynotuned by a professional and would also recomend that you rather not play around with the timing advance on any vechile if you do not have access to a dyno and to a proper air fuel ratio meter.
If you are melting the pluggs there is a rather good change that you have already done some damage to the piston tops.

Christo, maybe we should just elaborate some more when replying to our "North African cousin", in the sense of explaining that an engine needs x parts fuel and y parts air. The OP is from Egypt and his English is not that hot.

Re: my engine melting the spark plugs 2E engine
The fuel pump must be able to maintain 3 bar pressure over the entire rpm range under load, if you suspect it's not keeping up look at upgrading the pump.

Re: my engine melting the spark plugs 2E engine
If I'm not mistaken, your fuel pump should be delivering 3.5bar of pressure and your fuel pressure regulator on your fuel rail should be regulating that down to a constant 3 bar.

Pump should be fine then, try retarding (pulling back) your timing and see if the detonation (pinging) goes away.

Re: my engine melting the spark plugs 2E engine
You should also remember that the car is in Cairo, the weather is very hot there and this will contribute to a knocking condition.
I would retard the timing, you have lost lots of power by advancing it so far.

Re: my engine melting the spark plugs 2E engine
Guys please let us help this guy properly..
To do that the only real way would be to get it on a dyno. Retarding the timing might fix the immediate issue but how much. I can't see what management is used so that plays a role in what/how the ignition timing gets advanced or retarded by the management system.
Fuel pressure is also important.
What you need to understand is that what can and in all likelihood will kill a motor every time and quickly as well is knock or running lean when under load and at high rpm. This is exactly where you have the issue. Can you see/monitor the fuel pressure when you are driving the car on the road or the AFR's if you can not please get the car to someone that has a fuel pressure gauge, a AFR meter and a dyno so that you can see in a safe manner what is happening before you do any more damage to that motor.

Turn your ignition distributor slightly anti clock wise, see if that sorts out your melting plug issue.

Re: my engine melting the spark plugs 2E engine
Eish...
Not good then...Its a hit and miss affair at best and chances are that that motor will end up as coffee table in the near future.
You can retard it until it stops pinging even if you have a Fuel pressure issue but that will kill performance.
If it's MP9 it's just again a shining example of how utterly useless the knock sensor is.

Re: my engine melting the spark plugs 2E engine
+1 to what everyone said, put the ignition timing back to where it should be for a start. have you had the injectors checked? if they are not up to scratch they could be causing the lean mixture.
It is an ingenius solution to a problem that should have never existed in the 1st place...
