Hello, I have been looking at your archived postings and researching different designs of VSO conversions. I have yet to come across any that overcome the use of diesel or biodiesel as a startup/purging fuel. Does anyone know of cars that have been rigged to start on VSO even on cold days?
I have the outlines of a possible design here, and I am keen to hear what you think of it. SVO/WVO only design: - Single fuel tank and delivery system (SVO) - Fuel lines and possibly tank heated with engine coolant (pipe in pipe) and insulated - Electrical heating element (wire) inserted inside fuel lines close to the engine, near to the fuel pump and injectors. Also electrical heat tape wrapped around the outside of pump and injectors. - A small reservoir installed just before the fuel pump. This would consist of a collapsible bellows, also heated from the inside with heating wire. So with all this in place, it would be operated as follows: The electrical heaters would be turned on, as you might with glow plugs. These will bring the fuel that first needs to get to the engine up to temperature. In the worst case example, you might find all your SVO fuel solid in the morning. In this case the electrical heaters would melt and heat up the fuel close to the engine and the engine would begin to use up this and the fuel in the reservoir bellows, collapsing it as it did so. With the engine now running however, it could start to melt the rest of the fuel supply and replenish the reservoir. The electrical heaters would be controlled thermostatically to cool down and shut off as the fuel supply heats up sufficiently. The practicality of it all would depend to a great extent on how quickly the electrical heaters generally took to bring the SVO up to temp. Bear in mind that the volume of fuel contained in these ãend of the lineä components isnât very big and that the specific heat capacity of Veg oil is probably quite low. I would hope it could heat up quite quickly. You then have to weigh up waiting for a veg oil only car to heat up or the slightly cumbersome procedure of switching fuels in an SVO/diesel. I suppose in part I am trying to find a design that is easy for Joe public to buy and not think twice about. Anyway, I would appreciate any feedback on this, Thanks, Tim. __________________________________________________ Do You Yahoo!?
