Diesel Flow?

[makeitfit]

Can anyone tell me if the diesel is switched off completely on "close throttle"?
ie when you're going down a hill say with you foot OFF the loud pedal (I dont know why), is the diesel then off completely to the engine/?:augie
Need to know for the gas man:sly
Apparently I could blow the head off :lol

 

[Adz]

Just got the txt bk :augie

NO

On diesel or petrol


:thumbs

 

[makeitfit]

NO you dont know :augie or
NO the deisel isnt stopped completely:nenau

 

[Terranosaurus]

Depends on the year I think - mine switches it off but only above a certain road speed.

 

[Adz]

Sorry Pete :doh
Multi tasking to much :lol

Depends on the year I think

No it doesnt switch off completely according to my mate,not me...& he did say something about the year of manufactor

But i personally dont know :nenau

ahhh just give it a go pete...... fuc* the head, worry bout that later :lol:lol:lol:sly:naughty

 

[tezzer]

Thats what i would of thought...
But...
There will be vacum.!?

 

[extreme-4x4]

ok this is based on no fact at all, just something i read.

its the more modern engines , like the common rail diesel that shuts the fuel off when no use of loud button.

so based on the fact the t2 engine is an old one . my hunch is it dont shut off the fuel

 

[Terranosaurus]

Landy TD5 does it too and I don't think that common rail.

Its modern fly by wire type ECU controlled engines that do it. mechanical pumps can't do it.

I am prity sure mine cuts fuel

 

[makeitfit]

Well I guess I'll stick another electronic gizmo in then:augie
There's a switch off thing that stops a build up of gas on close throttle, just in case
Will need a signal from the throttle I guess

 

[Toolbox]

A good reason for having a clutch pedal switch and a neutral switch in the gearbox :thumbs that should already be there if it cuts fuel

Sorry been on the stupid sauce:augie
WHAT?:nenau

 

[Toolbox]

Sorry wasn’t referring to your last post, just referring to the cutting of the fuel on overrun that needs a clutch pedal switch to know when your foot is on the clutch to keep the engine going likewise a neutral switch in the gearbox so it knows when out of gear

 

[makeitfit]

So if your in gear and dont have your foot on the clutch, do you think the deisel is off then?
How does engine braking work on these oil burners?
Just need to make sure I'm not squirting in the old LPG when I shouldn't:augie
Big bangs n that
I'm pretty sure the gizmo is going in circuit now anyway just in case.

Yes I would say fuel is cut on Bosch system anyway when in gear , clutch up and over a certain rpm, with foot fully off the load pedal.

The engine is still turning and under compression regardless of the fuel so engine braking is still present. Its not a case of the engine stopping as in not turning.

I take it your putting gas in after the turbo, what pressure is the gas put in at?

 

[makeitfit]

Gas going in pre turbo, so it gets a good old mix up:sly
Not sure what the pressure is but mr gas does I hope.
He's done some London taxi jobs and they seem fine:thumbs
He's just done a Pajero and that goes like stink now:naughty

 

[Toolbox]

presure is not an issue pre turbo, you will have to take a few pics of the job when done:naughty

 

[makeitfit]

Oh yes pics on the go. Hope to get the tank and plumbing sorted Mon. then over to mr gas for the trickery bit:lol
He reckons a good 25% plus on the power/torque, and the Tunit guys say they're box will diddle the ecu into a bit more fuel so we should be in 180 BHP zone end of week:naughty
