“…The mean decrease in CO emission compared to pure diesel is 27.1%, 13.16%, 23.43% and 20.75% for CIB20, CIB20 + NPPD, CIB20 + DPPD and CIB20 + EHN, respectively. Diesel has a higher CN, that's why it exhibits high CO emissions compared to other blends (Sanjid et al, 2015a;Sanjid et al, 2013). Shorter ignition occurs due to the higher CN, providing better combustion in the engine and the combustion process increases when the oxygen content of the biodiesel fully reacts.…”

“…It is pertinent to predict some vital thermo-physical properties of biodiesel produced using activated clay in order to widen its application in biodiesel technology. Thermo-physical properties of biodiesel/diesel blends are very relevant for spray characterises, combustion, and emission characteristic in internal combustion engines (Olusegun et al 2019;Cheng et al 2013;Sanjid et al 2015). There are few or limited report on prediction of thermophysical properties of biodiesel produced from transesterification of edible and nonedible seed oils catalysed by activated clay.…”

The heterogeneous catalysis of African pear seed oil (APO) and modelling of some thermo-physical properties of the biodiesel was carried out. The oil was extracted with petroleum ether solvent and characterized with Association of Analytical Chemist (AOAC). The catalysts were synthesized by thermal, acid and alkaline activation of clay. The catalysts were characterized and used to transesterify the APO. The biodiesel produced were characterized using American Society for Testing Materials ASTM D6571 and some the thermo-physical properties such as density, kinematic viscosity and cetane number were modelled using multilinear regression analysis of Polymath version 5.0. The 52% yield of oil from the African pear seeds using the petroleum ether was comparable with yields obtained from other nonedible seeds. The transesterification of the oil was significantly affected by increase in process variables but the yield of methyl ester decreased beyond 3 h reaction time, 3 wt% catalyst concentration, 10:1 methanol/oil molar ratio, 60 oC reaction temperature and 300 rpm agitation speed. The physicochemical properties of the biodiesel produced meet the ASTM standard and were within the acceptable limits. The biodiesel produced via transesterification of APO using thermally, acid and alkaline activated catalyst have similar properties and can be blended to form a homogeneous fuel. The coefficients of determination are close to 1 while the root mean square value is less than 0.2. This shows that the multilinear regression can model the thermo-physical properties of the biodiesel.

“…The performance of a CI engine fuelled with biodiesel is observed to be similar to that of the engine fuelled with diesel. However, it has a major disadvantage of higher NO x emission than conventional diesel fuel [4][5][6][7].…”

A comparative experimental and numerical study is conducted to establish the significance of the use of single-component over multi-component representatives of biodiesel, diesel and their blend for predicting spray tip penetration. Methyl oleate and methyl laurate are used as single-component representative fuels for biodiesel. The pure components n-heptane, n-dodecane and n-tetradecane are used as single-component representative fuels for diesel. Methyl laurate is found to represent biodiesel of coconut, whereas methyl oleate is found to represent biodiesel having high percentage of long-chain fatty acid esters. The spray tip penetration of methyl oleate is found to be in good agreement with the measured spray tip penetration of karanja biodiesel. The spray tip penetration prediction of n-heptane fuel is closely following diesel spray tip penetration along with that of n-tetradecane and n-dodecane. The study suggests that the knowledge of the single-component representatives of biodiesel, diesel and their blend is sufficient to predict the spray tip penetration of the corresponding biodiesel, diesel and their blend under non-evaporating environment.
