Title: Start-up fuel settings
Post by: Ollie on November 08, 2005, 22:02:39
I've been told that you can alter the fuel settings for the initial start-up phase of the 300TDi. I find that my Laila smokes unecessarly upon start-up. I expect a little smoke, but she's only done 70K and is in tip top condition. She doesn't smoke after start-up.
To add to this, I never need to wait until the glow plug light goes out, she fires first time, no matter the weather. So I suspect the there is probably too much diesel upon cranking.
Can I adjust this?

Cheers
Ollie.

Ahh, I see very clearly now- he is jealous cos you have a good engine and he may have a duffer!

This could be tricky to sort!

I do have a thought ( don't laugh)

If Ollie never starts his motor with pre-heat then wouldn't this contribute to the smoke. Does the pre-heat give a better burn in the 1st instance rather than just relying on compression ?

Dunno myself, just guessing

Ollie it's really not worth bothering about - you could, if you're that bothered, take it to a diesel specialist as I believe its something to do with the timing - mine does the same and I asked Northampton diesel they said that the risks of altering the timing were greater tahn the problem - as to not needing the glow plugs more modern diesel ie the 200, 300 and td5's don't really need them unless it's really cold

Absolutely right, preheat is there for a reason - else it would have been cheaper for Land Rover to leave it out.  Use the preheat! :wink:

I have tried using the pre-heat, it makes no difference. The engine starts straight away with or without it, and smokes just as much.
I just feel for all those in Tesco's car park that I regulary cover in smog :oops:

Ollie,

 that level of smoke does sound a like excessive - when i start mine it puffs out a very small cloud of grey/black then theres nothing (until
I thrash it!)

If you speak with colintandy on here here is all clued up on fuel pump tinkering and may be able to help you.
