Diesel + lpg = big mpg

It might be similar to the carburettor of a forklift

The set-up is designed for light duty 4&6 cylinder vehicles..the impco regulator is like that of a fork truck and only releases vapor upon making of the adjustable pressure switch..Also, it must have a vacuum or it will not release the 1.5 psi of lpg..I installed the adjustable sparge tube about a foot away from the turbo, a few inches down stream of the MAF..After initial testing i will be install a make on 140 degree switch that will be another saftey in line with the pressure switch. Dropped another screw in the abyss, so I'm calling it a night...

Cool,

I have been meaning to do something similar.

BUT BE AWARE!

These new diesels have a small quantity of diesel pre injected to smoothe out the « diesel feeling » of these new generation engines.

If you have a combustible gas, it will start burning! This is before TDC and will have negative effects on your engine!

You can investigate when there is no pre injection (higher rpms) or have it tuned out.

Read the paper in one of my previous posts.

Please be careful.

I tried LPG it was alright, but water methanol is where it's at.

Did yours have preinjection?

[Putters]

So, i finally got it all back together and fitted nicely(haha)in place behind the center console..mind you, this was the initial run at the lowest settings..when engaged, the regulator made funny farting noises..also, i could hear the tiny tank dumping and it was cold to the touch, after i got on it a few times to see if there were any seat of the pants differences..i have to say that is does feel alot like the water/meth injection(oil pan 4)..although i was only running it at highway speeds, due to the pre injection that teoman had mentioned..still have to investigate more into this, first I've heard of such thing..that being said, it might be right were i want it, for mileage, only time will tell..I had previously read a post on tdiclub were the user said he would only change out a 1lbs tank every two weeks! If this small tank last one week i'll be shocked!

Where do you live?

Does your tank have a snorkel? (Or is it cqlled a down tube?, i.e do you have liquid exiting your tank or gas?)

[Putters]

I live in Albuquerque, NM..The tank is upright, so mostly gas, but the regulator is built to vaporize and also has a in line filter dryer that helps dry out any liquid vapor.

I am assuming abq is Where Braking Bad was filmed so It would be a hot climate.

My old car had LPG and it ised engine coolant to vaporize the LPG. I live in Istanbul where it is hot and can be humid during the summer. It seemed to me that letting that « cold » go to waste was a terrible Idea so I wanted to build an in cabin vaporizer before the coolant based vaporizer so that it would absorb the heat from the cabin.

My vaporized had liquid going to it, with your setup the vaporization is tanking place in the tank, so putting a fan on the tank directed at you could be an interesting thing to explore.

Alas I never got around to it and the car developed problems and it appeared more economical to me to sell it.
