What do you think is on the end of an injector? It is metered
orifice same as a jet at end of the solenoid or mechanical pump. Trucker slang this line is metered by a button. In this example you may see the jet: #8, piston: #13, inlet fuel line: # 7, solenoid: #6: http://www.tpub.com/content/dieselge...84-24P_143.htm It's not complicated. I hope you are learning something along with frustrating me.

Say what???????????????? If you were around for the early get
around the SMOG compliance of the seventies conversions before they killed everyone, you'd know how false that statement is!!!!!!!

Most truckers have less knowledge of diesel fuel control systems than they do of gynecology. "Buttons" are Cummins parlance for a sized part controlling fuel delivery in the PT fuel system, which along with Detroit racks is a thing of interest only to antique collectors and a few off-road operators today. |

That is total bullsh*t! Every fuel has a different BTUs of energy,
just like when the hot rodder switches from gasoline to a alcohol he must drill the jets out to twice the size to pass four time the fuel. That just so..... basic!

don't believe so - what maintenance were you thinking of specifically ?

You just look at a Diesel and see if you can figure it out:

It's basic, but the numbers are not quite right. Alcohol requires between 2
and 2.2 times the fuel as gasoline, and when enlarging the jets and other fuel orifices, you need to double the area, not the diameter or you will have an engine that runs extremely rich. http://journeytoforever.org/biofuel_...drane.html#ch6 Chris "L.W.

My hot rod days were alcohol and compressed air via a Jimmy 671.
More air more fuel. God Bless America, ßill O|||||||O http://www.billhughes.com/ c wrote: > > It's basic, but the numbers are not quite right.

Now you're comparing apples to oranges. A supercharged gasoline engine
converted to alcohol will still require 2 to 2.2 times the fuel as it did when running on gasoline. If you take a normally aspirated gasoline engine, convert it to alcohol AND supercharge it, then maybe it will require 4 times the fuel. You take any engine properly tuned for gasoline and double the diameter of the fuel metering orifices, and you will have an engine that runs VERY rich, if at all. Chris "L.W.

The post you answered, I wrote I was a "hot rodder". And that was
to get more energy out of alcohol than I could get ordinarily out of supercharged gas. You brought the oranges into this. You do know what the water in that alcohol will do to your engine you plan to drive on the street, right?
