Abstract
ABSTRACT
An experimental study has been carried out for investigating effect of corn and
soybean biodiesel blends (C20 and S20) with diesel fuel on performance of diesel
engine. Tests are conducted with different engine speeds, loads and IP of 180, 190
and 200 bar. A/F, mf, Texh, Twall, Pcyl and position of maximum pressure are studied.
For high engine speeds, loads and IP, mass of fuel injected, BP, Bth, V, TWall and
Pcyl for S20 are higher than for diesel fuel while A/F ratio, BSCF and Texh for S20 are
lower than for diesel fuel. For 190 bar as IP, Pmax for C20 is higher than for diesel fuel
and S20. With 200 bar as IP, Pmax for diesel fuel is higher than for C20 and S20 due
to low viscosity, good mixing and high heating value. Position of Pmax attains within
14-18 CA deg ATDC for all fuels.
