HOW TO RUN A DIESEL VEHICLE ON VEGETABLE OIL
There are several different systems but due to extensive research we are able to offer what we consider to be the best solution.
For a Two Tank System. In order to successfully run your vehicle on vegetable oil, it must be heated and introduced to a warm engine. This system is designed so that you start up normally on Diesel, switch over to vegetable oil when at normal operating temperature, run all day, if you stop during the day for an hour or so you do not need to switch back to diesel because the engine will still be warm, at the end of the day switch back to diesel, run for a few minutes and switch off, this ensures engine can be started next morning on Diesel.
The first thing to find out is whether your vehicle is Common Rail (usually found on newer vehicles). Or if not, your rotary or inline injector pump is a Bosch or a Lucas/Cav. Bosch and its copies are particularly tolerant of veg oil and usually convert OK, Lucas less so because it is inadvisable to leave cold veg oil in this type of pump. However if the startup and stop rules as explained above, are adhered to it should also be OK. The Quick Purge with Alarm is particularly useful anyway, but for Lucas equipped vehicles it is a godsend as it will ensure that you switch to diesel for your next mornings startup.
Using vegetable oil in an un-modified vehicle is not recommended as starting from cold can be problematic in terms of correct atomization, cold veg oil can be about five times thicker than Diesel, if the fuel is not atomized correctly it can form big globules resulting in unburned fuels coming from exhaust and may cause polymerization on the bores creating premature engine wear and increased engine oil contamination. Even mixing veg oil with diesel can cause the same problems to a greater or lesser extent, depending on the amounts used, even if the vehicle appears to start ok. Running in this manner would likely be suicidal for an unmodified Lucas pump.
For Bosch inline and rotary injection pumps and its clones, Nippon Denso, Diesel Kiki, Doowon, Zexel etc, and tentatively Lucas the Two Tank DIY KIT001 8mm 12v is £630.44 inc vat with 22l start-up diesel tank (vegetable oil goes into original tank so range is unaffected) and FREE quick purge timer with safety warning alarm (worth around £70.00). It includes everything necessary, except coolant hose kit as we do not normally know the size of the hoses coming to and from your heater matrix (going through the bulkhead) we sell these kits separately, however in KIT001 it is FREE. The 1/2" kit costs £20.40 if your heater hose is 1/2" internal diameter this is all you will need, if 5/8" it is £21.60, if 3/4" £22.80 see here. All in the above kit Fully fitted £1350.00 inc vat. Usually takes one day to fit. If required, larger tanks can be fitted for vegetable oil, using your existing tank for diesel at extra cost. For vehicles, usually larger vans cars and commercials 10mm and 13mm kits are available either 12v or 24v.
For Common Rail and VW Unit Injector(CDi and PD) 2 tank system price, fully fitted around £1675.00 inc VAT. Usually takes two days to fit.
A DIY kit for most CDi and VW PD is available. Price around £863.21 for cars, vans and small commercials.
The 22l jerry can sized tank can be fitted in boot, or on the wheel arch if it is a van, it has a very small footprint so takes up little room, this has a breather tube so you get no nasty smells.
Conversions are at present carried out by us at Wolverhampton. You may be able to find a local mechanic who will be prepared to install for you, this has been successful for many customers. If you are mechanically minded, then the DIY kit is for you.
Fuel Consumption and Power is similar to that of Diesel.
Veg oil can be obtained from supermarkets and cash & carry or wholesalers. It can also be collected waste, processed and used. It can also be cold pressed from rapeseed. Rapeseed Oil is the best to use.
There is a12 months guarantee on all parts and fitting supplied by Dieselveg
In 1996, France’s Centre for
International Cooperation in Developing Agro technical Research fuelled a
Renault on rapeseed oil for 61,000 miles. Proving there are alternative fuels
that can be used successfully without engine damage as long as the guidelines
are followed, the kits are of a good standard and competent professionals carry
out the installation work.
Extract from the Veggievan:
On the smell of an oily french fry
Josh and Kaia Tickell have an obsession.
They collected used oil from fast food joints, cook it up with some special ingredients and then pour it into their Diesel 'Veggie Van'.
They have toured the US on vegetable oil, and are spreading the word about this clean and great smelling fuel.
Their story is as follows
Powered by vegetable oil, the Veggie Van took us 16,000 kilometers across the United States.
The Van visited 20 major cities and 25 states where people smelled the clean french fry-like exhaust.
Over 40 million people saw the multi coloured Veggie Van drive across their television screens. Thousands attended presentations about it, and hundreds of thousands more read about the van in their local newspapers and on the internet at the Veggie Van website. More
