Alcohol cant be used as fuel in diesel engines because
1)The engine should modified first,that is the enlargement
of the carburetor jet(s)
2)In addition to the carburetor jets, there is also the
problem of cold starting.
3)Alcohol has a higher latent heat of vaporization than
gasoline and requires more manifold heat to keep the mixture
in the vapor state.
4)The main problem is in the lubrication of the injectors.

There are many disadvantages to using alcohols, particularly methyl and ethyl alcohol.
Alcohols may corrode certain materials used in engines.

Although these alcohols, when used near their stoichiometric air-fuel ratios, produce more power
