I have posted this on the "Biodiesel and SVO Forums" site as well, but hopefully all the Hilux owners will come out of the woodwork here. In fact anyone with two bob to put in!
I need a bit of help sorting out my conversion. I will be using canola oil in a 1990 2.8L Hilux which is indirect injection using a rotary injection pump.It runs well, though never especially powerful and has done 348K km. Also the climate in Western Australia is pretty warm so my oil is always liquid. Here's my idea of how it will run:
Start on diesel, after letting things warm up a bit, start the pump pushing oil through the WVO side of things, returning to tank until the temp after the FPHE is satisfactory, then switch to run on WVO, the pump turns off and the IP fuel return, after a delay, is switched to the oil tank.
Any comments?
I'm not sure if the pump is necessary once I am running on WVO, but it would be simple to change.
I will probably be using two fuel shut-off valves for each of the 3-way pollack type in my diagram, to better cope with the heat.
The fuel lines will be HOH, all 4 lines (2 coolant, 2 fuel) bundled together.
The fuel tank will be from a wreckers, with copper pipe brazed to the bottom to run the coolant through. I drive a lot on rough roads and I don't want any water in fuel issues if something vibrates enough to crack and leak so no in-tank heating.
I am trying to find a non-copper brazed FPHE so there will be no copper/oil contact in the system, and switching after it to avoid heating the diesel.
I have been doing a far bit of lurking/searching on the relevant forums and tried to incorporate the ideas I liked.
Thanks,
Steve.
