Turbo diesel, I regularly leave it on tickover for half an hour at a time to charge the leisure battery.
Lately I've noticed when I drive away it puts out clouds of smoke as I accelerate which slowly clears then it runs "clean", until after the next time it sits on tickover.
Some research suggests that this is caused because diesels run very cold on tickover which causes glazing to cylinder walls.
So, (if this is the cause of the smoking) does anyone know of an additive that will remove the glazing?
My campervan (I'm assuming that's what you're talking about) has a charging system which charges both van and leisure batteries when it's plugged in to the mains. Every week or 2 I plug it in for a few hours if we're not using it, and that seems to keep everything healthy.
If it's only when if you've left it idling that you get a problem, could you do this instead, to keep the batteries fresh?
IMO it needs a run. Might as well really-does it all good, blows any condensation out of the exhaust/gearbox & get the brakes & discs all clean etc.
as far as the charging goes I leave mine on a iddly 5 amp charger overnight. The battery on mine is prolly the same size as a leisure battery, so I guess 24 hours or whatever the charger is indicating is about correct for yours.
IMO if you're going to use snake oil then Millers Diesel Power Plus (or whatever it's called this year) is good stuff. Been using it for years. Or run the tank a bit low & shove some Shell V power into it & take it for an italian tuneup. Oh yeah-one other thing. Once it's all warm it's a good thing to bounce it off the redline a couple of times say once a month. under load that is-not dip the clutch!
I forgot about this. Decarbonise. I seen it on Wheeler dealers
Terraclean as seen on Wheeler Dealers...my results!
Dcent Solar panels are expensive and budget is tight right now.
I just need an additive to remove glazing, then plan to change thermostat and remove viscous fan to raise engine temp on tickover.
JJ. Knows what he wants, just can't find it. :-)
Cylinder glazing is removed with a hone.
The better news is that glazed bores can't be very top of the list of likely reasons for a smoky Diesel engine.
Valve stem oil seals?
My old Transit used to chuck out a bit of blue smoke after being started and also after it had been idling for a while and the mechanic suggested that as it had done 260 000+ miles at the time it could well be valve stem oil seals.
Carried on for another 10 000 after it and just used slightly more oil.
How do you think a diesel generator motor runs at very low rpm day after day without glazing the bores? a lot of the problems caused to diesel motors are the short runs, they need good long runs to burn all the deposits in the likes of the egr valve and turbo and turbo pipes, at tick over diesels run fairly cold, hence not burning the deposits and when you kick it into life you get a cloud of smoke.
