Mervin goes on line

Okay, so I've been runnign the van (Mervin) on a mix of between 60 and 70% veg oil to 40 to 30% diesel for the last month. I finally ot round to fitting the Veg Oil heater, as with the winter months coming a little heat assistance will be needed to combust the fuel properly. This should allow me to run at about 85% Veg to a mix of 15% diesel over the winter.
Also completed today was the additional of the Hydrogen Booster, to mix HHO (Browns Gas) with the fuel mix, which should yeild an additional 15% increase in MPG. Watch this space for the results. My initial estimate of 50 MPG was over enthusiatic. It's actually about 42 MPG I've been getting - it helps to know how big the fuel tank is (42 litres as it happens) as I don;t have any reliable method of measuring how much Veg Oil I am pumping in. With that as a baseline to work from we'll have to see how much the Hydrogen fuel helps. At a 15% increase we ought to be seeing 48 MPG over the next tankful, although it may take a while to settle in.
I have also invested in some other fuel saving devices, a magnetic fuel saver which proports to rearrange the fuel particles for less coagulation and better combustion, plus an electronic engine management system which basically turns off the engine when stationary in traffic, and automatically starts it again when you move off - rather like the new VW Polo and Golf apparently, although this is a 1990's ZEMCO system. Full report to follow in due course, once it's all fitted up and running.
