LPG PROPANE INJECTION KIT VIDEO/PICS

[touaregv10tdi]

Hi folks,
I am running propane injection in my old Beetle TDi for quite sometime now. I am happy to get 64MPG and have a power take off at traffic lights.
I have lowered my Injection quantity to 6.8, so no smoke, less NOx.
I have uploaded a video how my set up looks in the beetle.

VIDEO LPG INJECTION KIT INSTALLED.

Pretty neat kit. Looks like a very clean install. The boost in mileage alone makes this very attractive.

I'm looking I doing this on my 2005 Passat. What was your mileage before injection I see you in your video you talk about mileage increase 40% power has also increased is that a 40% mileage increase or 40% power increase. From guessing right you were making about 46 mi to the gallon straight diesel now you're making 64 mi to the gallon diesel propane so this will save about 0.01$ per mile. That's not bad if you put the miles on

Pretty cool, only thing that worries me is the LPG tank needs to be rotated 180 degrees for the blow back valve.

 

[CleverUserName]

Is that 64 MPGs an average consumption of the 2 fuels together?

Correct. 64 MPH is combined Diesel/LPG .

Rotating the tank is just a matter of losing the clamps and rotating it. 1/2 second operation.

Cool setup. Im curious as to how the overall mixture is not overly rich? The fuel tables in the ecm request a certain mass airflow (grams/min) via the MAF sensor and then adjusts the turbo veins accordingly. I would think that by adding fuel to the mix that the ECM does not know about then it may be too rich? The ECM only request so much air based on how much fuel it needs to inject. It only knows about the diesel. I bet you could possibly get better mileage with some custom programming. Maybe its not an issue because at cruise a diesel is already 'lean compared to a gasser' and it already has extra air in cylinder to help burn the propane. Yeah, I bet its way cleaner as the propane will help burn more complete.

On that not; the propane is injected after the MAF.
I remember back in 2003 when Saddan Hussein set fire to the oil wells, we had a hard time keeping the bulldozers running slow because it kept breathing natural gas after we extinguished the fire in the wells; .We had engines running on redline rpms all day but never caused any damage.

Its a legitimate issue. The ECM will balance the mixture and more or less neutralize any mpg gains. The o2 signal has to be modified also to "fool" the ECM if your looking to "partially replace" the fuel with an alternate source like water meth, propain or hydrogen. There are electronic fuel injection (E.F.I.E.) add on units that modify MAF/MAP, ECT, AIT, O2, so you retain the proper A/F balance when adding alternative/additional fuel source. I'm playing with on demand hydrogen on my Toyota gas 3mz fe 3.3. I've chosen a simple OBDII port plug n play E.F.I.E. unit modified to "modify" the ECU for hydrogen.

 

[touaregv10tdi]

Well, I am doing 64 MPG with this set up, I think I am happy with it. This is a turbo diesel so there is no comparisson with a Toyota gas engine.

 

[AverageAndy]

Cool idea. Used to be in AZ you could get an "alternative fuel" registration with a propane system added on. This would allow legal HOV use with only a driver. However, they have since restricted it to pure CNG or LP run vehicles (plus full electric, hydrogen, etc.). Also, the benefit or EV plate registration being $25/year has ended. It is now calculated by assessed value, just like every other vehicle.

Sounds like its working well. My point was either petrol or diesel you can benifit either h/p or mpg or even both with an E.F.I.E. because an OBDII ECM will by design set/adjust A/F ratio to set parameters.

 

[CleverUserName]

Has anybody tried this with hydrogen instead of propane? Wondering if a small electrolysis unit in the trunk could supply the secondary fuel for combustion and net an improvement in MPGs

 

[JELLOWSUBMARINE]

Hydrogen is supposedly quite responsive to diesel especially turbo/diesel. To see mpg you'll need to use an E.F.I.E. device to modify your ECU or it will negate alternate fuel.

I'm presently working on a 1-2 LPM on demand set up for my non ecu n/a 1.6.d. Kind of a tester vehicle

I don’t see why you would need to do that. The gas created by electrolysis is called Brown’s Gas and is 2/3 hydrogen + 1/3 oxygen. You just need good mixing prior to combustion and it can be fed into the intake by a demand system. The diesel IQ and injection timing can by altered for this experiment using VCDS without doing custom tuning.

The energy needed to fuel electrolysis would need to be provided by the alternator, so there will be a net energy loss but if there is an efficiency increase or catalyst effect then the MPGs may be gained over diesel fuel alone.

 

[touaregv10tdi]

For Hydrogen I would prefer not to combine it with diesel.

That's a very nice car and very well taken care of, you should be very proud of it. I have always liked the Turbo S interior and several times have thought about buying one. I see you've added the dead pedal and pedal covers, shift knob and boot as well!

I think it's interesting that you're running a Mk4 steering wheel too, wouldn't a leather covered one be nice for that?

Steve

 

[touaregv10tdi]

Indeed. I the very near future I will upgrade the steering wheel. I hate the half moon OEM Beetle Airbag/Steering wheel combo.

Trying to figure out from pics which seats those are..? With two adjusters!

These seats are from the 2003 VW Turbo S gas version. It is quite rare to find these seats out there, for me, it was a lucky shot at a local Yard. Jack pot!
