Cold Start

EnviroImports.com · Post by **EnviroImports.com** » Tue May 15, 2007 9:45 pm

mine was the same knob, but the lettering was not there, only the symble, the symble is for choke, I wonder if thos clever buggers made a duel control, pull for throttle and twist for choke?
hmmm, guess I will wait to see how my next one comes in.
oh and nice clean pic, :D

pull for throttle and twist for choke?

this is why I'm trying to figure out the proper use of the control, I know how to use it to adjust the idle speed, what I'm trying to figure out is the correct usage to help with cold starting.

what I've noticed in the way of operation is that pulling on it increases the idle speed, and turning it 90 degrees clockwise locks it in place to maintain that speed, I haven't noticed any other way of operating the knob... yet people talk about setting it for cold start... I don't know what they mean.

nice clean pic,

friend's van is pretty much mint... I'm actually rather jealous...

My thoughts on this:

The knob is strictly for throttle control, bring the idle up in order to produce more heat, in order to get the thing to burn fuel better.

There is no choke just glow plugs and manual thottle. Newer diesels don't use glow plugs but use more sophisticated sensors etc to retard timing and so forth in colder temperatures. I don't think diesels use chokes at least not in the traditional way as per gasoline motors. Now I could be waaaay off base, but this is my understanding. Correct me if I'm wrong.

My throttle pulls easily and is clearly linked to the pedal linkage. If yours is tough to pull, presumably it is kinked or corroded or in need of some lube. But then again, who isn't.

Sorry about the confusion, I call it a cold start knob as that what it was labelled on my old Mazda diesel and yard tractor. Also, I only use my knob when it is cold to start - hence cold start knob. It is just a throttle control, you can watch it work with the hood up and when the pedal moves.

I don't think there is a choke on diesels that operates as gas engines by reducing the flow of air through the carburator (sic) as there really is no need for that.

New diesels definatly Do have glow plugs, our 06 dodge certanly does, as does my Smart car, for tractor trailer size diesels dont have glow plugs, some of the 3-5 ton cab overs have glow plugs, but once you go up to big power its a much different design, same basics, but alot more compression and Much higher pressure injection pump

Never heard of biocide, do you need it every time you fill up, or just once in ???.

howes fuel treatment is good, but go buy your self a bottle of biocide, any truckstop, truck supply store, Comercial marine shop will have it, run a couple oz of that in a full tank to clean your system out,

alot of people have not heard of biocide, but you will if you dont use it, eventually the bacteria that grows in diesel fuel will take out an integral part, if you have never used it befor, use it twice in a row, after that you should only put in about once a month- month'n'half. if you cant find it . go to trotac marine by hellijet. they have it and pnr western star carries it, I would stop usins the wynns if it were my van as its a good lubricant and you need that but you dont need the antijell qualities(unless its -20 ), I would get the raycor diesel lubricant at trotac and they also have the biocide. fuel lube should be with every other fueling.

also Coast Industrial 562 duplin rd has good fuel lube and theysell biocide but their biocide is a much stronger mix,

the fuel lube is a necessity since there is such low amount of sulfer in the fuel now, and that WAS what lubricated your seals in the pump.

We're using Howes now, recommended by a guy who has had diesels since year dot, currently has two dodge trucks with mega miles. It has certainly made a difference in both our vehicles.

We'll find the biocide and use that as well, on both the deli and the dodge. I think we get spark plugs for our boat at Trotac, so can kill two birds with one stone.

Thanks for the advice.

dont get me wrong, howes is fine, I just dont like putting antijell into my fuel if I dont need to.
just a personal preference.
and just to add chit chat "that guy must be crazy"
in the summer time i dont put in any lubricants, I put in some clean vegi oil. but only in the summer time. as I dont want it to thicken.
