Data on combustion chamber measurements of a diesel engine fuelled with biodiesel of and fatty acid distillates.

Data in this paper covers in-cylinder pressure and volume, crank angle degrees as time magnitude, first derivate of in-cylinder pressure, admission pressure and injection pressure in a diesel engine fuelled with biodiesel. This data brings additional information such as ignition delay and rate of heat released. As condensed information, some graphs were obtained and are into the database such as in-cylinder vs.

Data on the thermochemical potential of six Cuban biomasses as bioenergy sources.

Data on the rapid, elemental and calorimetric analysis, such as ash melting behaviour and thermogravimetric profiles of six Cuban biomass feedstock are shown, in order to assess their potential for bioenergy production. The studied biomasses are husk, husk, , , and . Seed, kernels or stems and algae were characterized by weight.
