Thread: Lpg diesel fumigation

very interesting hymie..what are the performance/economy benefits of your system?

really?



Then whats that about....

LPG fumigation is currently the undisputed holder of the "hype and BS" trophy.

I can see a hose clamp and hose protruding from the bottom right of the converter, this is why i asked even though he said no coolant flow.

To Loanrangie,
The hose at the bottom of the converter is the vapour outlet to the engine.
To Edddo,
Performance wise, it will wheelspin as the turbo boosts in 1st high, which is why I am twisting axles
Economy wise, I was getting 650-700 K's out of a tank of Diesel, with Gas It's over 800 and touching 1000 on long trips.
At 7500 k's since my last oil change I am not getting any staining on my fingers from the oil on the dipstick, so I believe the engine is burning cleaner.

(The grease nipple in the Pic is to get people thinking)

Thanks for the clarification Hymie, i'll have to have a look at my converter and try and see why the grease nipple is there but iguessing to keep the diaphram spring/ lever lubed ? Is the inline mixture screw the only metering device ? Is the inline solenoid so you can cut the supply quicker ( or is it the only cut off used ) pics of tank used and location would be appreciated - so many questions !

No dramas, I'm here to help if I can.
The grease nipple is just there blanking the coolant gallery, like I said, it gets people guessing
The inline screw valve is the flow adjustment, most fitters just go with a small jet and allow no adjustment, if it's opened up too much it will knock. Basicly the valve is screwed shut and the vapour that gets through the thread is enough, it can be opened about 1/8 to 1/4 of a turn more but after that she knocks.
Theres are 2 solenoids, 1 is the main shut off that cuts flow when the ignition is off, the other opens up when the gas is switched on at the dash.
There is also a microswitch on the fuel rack so there in no gas flow at idle.
I'll get a few more pics tonight of the tank etc.

The one thing I really like about the diesel gas thing is this...

yep you get more distance from a tank of dieso... but your adding an additional fuel source to the engine... If you could run the engine on just the lpg alone how far would it go on just the lpg.. how far would it go on just dieso alone.

now add those 2 distances together.

if that doesnt add up to less than what you actually covered your not really saving money are ya. (this is one of the clever marketing ploys)

but.... in terms of cleanliness of running, smoothenss of running and the aditional power that can me made available its worth looking at.

If you are adding only a sniff of lpg then a small tank (say 9kg bbq size) should last for a full tank of diesel, so roughly $120 for a tank of dieso and if filled at a servo say $5 of lpg to get say 1000klm along with extra power and smoother cleaner running, is worth the conversion. Biggest advantage would be to those that tow a van/ boat/trailer etc . Not worth the 3-4k the professional install would be though.
