[Gasification] WET ETHANOL IN DIESEL ENGINES

[Benjamin Domingo Bof]

Martin you are right. 
In Brazil was build engines to use "alcoolita"; 
ethanol mix with dinitroethylene glycol five percent. 
Was made Perkins 4-236, Mercedes OM-314 and OM-352.
 Piston is different and injection timing varies to 10 degrees TDC.
Very good idea to use tar from wood pyrolisis mixed with diesel.
 It was made also.
Not only research must be in fuels too in engines adapting it
to different ways of combustion.
Regards, Ben

Inject the as one would in a gasoline engine. Retain the diesel injection for creating a pilot flame.

FIAT will be doing the field tests in Brazil on an ethanol engine like this. We should know more by the end of the year. 

IMO, those "experts" don't live & breath engine. A true engine expert's hobby will be motorsprot racing.  

As a side note, this is how I will start testing pyrolysis tar/ethanol blend on a diesel this year. I'm trying to avoid having to "upgrade" the pyrolysis tar.

>  Contrary to the opinion of most "experts", diesel engines can be run on pure alcohol. The main problem is in the lubrication of the injectors. This is solved by the addition of 5-20% vegetable oil (or other suitable lubricant) to the alcohol. It is also possible to make a diesel "gasohol" with up to 80% alcohol. Since alcohol and oil will not mix when water is present, both the alcohol and the oil must be anhydrous. Different engines may also require adjustment of the metering pump for optimum performance. Diesel engines, especially turbocharged diesels, may also be run with an alcohol/water injection system as described later.
