Hi,
Has anyone experience in running a direct injection changfa with veggie oil or bio diesel?

Best greetings from Germany,

Your direct injection engine should not have any problems with biodiesel.

Indirect injection engines are more forgiving of inadequately heated veggie oil.  For a direct injected engine, you should be sure that your veggie oil is plenty hot before injecting.  I suggest that you pre-heat the veggie oil to about 70ºC before the injector pump and the injector line to at least 100ºC before the injector.

Hi I have been reading about a few guys experience with mixing straight veggie oil with some gasoline at a 1-8 mix for warm weather. The idea is the gas thins the veg oil so it can be injected with out heat.

I have been using a 2-1 mix as an additive for my Mercedes diesel with good results. I have added 1 gallon of this mix to about 15 gallons of pump diesel. The car runs better I think and definately idles better.

From what I understand there are IDI and DI type changfa's.. it would be good to know which ones are which?
 I see Luismc's engine in this thread is DI from the pictures he posted...

Hi,
thank you for your replies.

What do you mean, fatty? S-engines have swirl compustion chamber; ZS-engines direct injection.

I can get many WVO for free but should I "burn" the filtered WVO in the engine? I don't want to clean so often the combustion chamber, piston, etc..
The engine won't be have many cold starts. We need it to produce power and heat around the clock.

Here's a picture of mine:

Sorry for my bad English, I'm only 16 years old and I'm not very good in it.  :-\

Best greetings,
Michael
