ginamit nila
97% strained used vegetable oil
3% non kerosine white spirit

on a completely drain gas tank of a volvo diesel car

after bleeding vroom......

mga diesel peeps ok ba ito?
rsnald your comment please?

di rin ako maka comment dito. theoretical lang din maisasagot ko e. personally, I don't feel comfortable putting in used or raw vegetable oil sa diesel engine ko. why? marami kasing impurities sa raw vegetable oil lalo na sa used veggie oil that could gum up your engine. saka rancid na ang used vegetable oil e, some of the materials present in it may not be combustible anymore.
pwede pa yung by-product ng vegetable oil, yung biodiesel which, incidentally is now being tested by the Dept of Energy. Busy sila ngayon trying to finalize the specs of the Philippine version of the European standards for biodiesel. Our lab is involved in doing the interlaboratory tests, (chemical tests lang, not the engine tests which is being handled by DoE). Sa Europe kasi, ang base ng biodiesel e rapeseed oil, sa U.S., soyabean, dito sa tin coco oil ang gagamitin, so natural lang na iba ang specs natin. saka tropical condition tayo e, yung ibang specs na di kailangan sa temperature conditions natin ay tatanggalin.

pero alam nyo ba na (minor trivia ulit) nung unang i-demo ni Rudolf Diesel ang makina nya sa France nung 1900, ang fuel na ginamit nya ay................. peanut oil!!!
:shock: :shock:
so it's not surprising that people are now looking at vegetable oil as possible alternative to diesel fuel. for more reading materials related to this thread... read on na lang.

pwede daw gamitin provided merong mga modifications.

saw that sa replay ng Top Gear kanina.. gulat nga ako eh.. sana nga madevelop ng pinas yung coco diesel... para naman bumaba ang presyo ng diesel....

veggie oil should work fine. problem is getting that additive done right... sabi nila kailangan pa i-stand for a few weeks yung mixture.

opponents bound to launch a FUD campaign on this would be the local oil companies (lost revenue) and the government (lost revenue -- taxes). maybe we could try it out ourselves! i have a tired old 4D56 that is about ready to retire.

better kung cocodiesel na lang i-try natin. you'd risk major damage sa 4D56 mo without the mods mentioned in the links i mentioned above. tingnan natin if cocodiesel can revive your old tired 4d56. simple lang naman test, just blend 1%-5% by volume of cocodiesel to regular diesel. then if you like have the emissions checked, before and after (magastos nga lang to). record your mileage na rin siguro, before and after. at kung gusto mo pa, i pacheck mo na rin power output, before and after. or mas matipid, judge mo na lang thru power output when you drive it.

iniisip ko lang...

bakit tayo natatakot na maglagay ng cooking oil sa diesel engine?

diesel is one of the lowest levels of refinement in fuel, and cooking oil is at one of the highest levels. perhaps higher than even the premium petrols -- because it's meant to come in contact with food meant for human consumption. natural lang na mas malinis ang cooking oil sa kahit anong gasolina na binibili natin.

yung napupulot niyang particulates habang pinangluluto, madali lang i-filter at combustible (pagkain yun eh!). hindi naman siguro magkakaroon ng sub-visible chicken chunks yon, at kung ma-break up mo yung chicken na ganoon kaliit, hydrogen-carbon base din naman ang laman, kaya ayos lang.

nakakagutom talaga pag-usapan yung biodiesel na yan. makakain nga muna

**fierari** · November 19th, 2002 06:32 PM

takot din kasi ako baka iba ang properties nyan na pwede makasira sa injection pump. di kaya mamumoo yan sa loob or pag malamig ang panahon manigas sila sa loob? cooking oil di ba mabilis mag freeze?
