Statistical Analysis of Diesel Engine Performance for Castor and Jatropha Biodiesel-Blended Fuel

Abstract

Vegetable oils and their methyl/ethyl esters are alternative renewable fuels for compression ignition engines. Asian countries are not self-sufficient in edible oil and are exploring non-edible seed oils, like jatropha and castor as biodiesel raw materials. In the present study jatropha and castor oil were used for the preparation of biodiesel by the transesterification process. Diesel and jatropha oil methyl ester (JOME) blends were used to conduct short-term engine performance tests at varying loads. Similar tests were conducted with castor oil methyl ester (COME). The engine parameters were recorded and compared for the prepared blends. The best engine operating condition based on lower brake specific fuel consumption and higher brake thermal efficiency were identified and compared. The maximum thermal efficiency was observed at 13% substitution of COME in diesel and 18% for JOME in diesel. An analysis of variance test was applied to the observed data for both the fuels. Results indicated for COME, F = 2.397, that there is no significant effect on fuel consumption with the fuel type. There is a significant effect on fuel consumption and thermal efficiency with % of load. For F = 5.69 there is a significant effect on thermal efficiency with the fuel type. Similar trends were observed with JOME blends. These trends indicated that blends in the ratio of 0-20% by volume of biodiesel can be added to neat diesel without any change in the hardware of the engine.

Comparative study of diesel engine performance and emission with soybean and waste oil biodiesel fuels

“…By comparing Figure 2 and Figure 3, it is evident that the maximum torque and power reflect each other, which is expected as torque and power are directly related [51]. The total torque output decreases gradually with the increase of biodiesel blends [52]. However, the lower torque production for B50 is expected because the property of the biodiesel blends influenced the in-cylinder combustion in the diesel engine [53].…”

“…This increasing energy demand should be met by a cleaner source of energy [3,4]. Biodiesel is made from renewable plant or animal fats (tallow) that contain fatty acids [5][6][7][8], which can be converted into biodiesel using the transesterification reaction [9,10]. Biodiesel can also be produced from a wide array of feedstocks such as waste cooking oil, edible and non-edible oil seeds, wood and wood waste etc.…”

Pure Polyurethane and Castor Oil Based Polyurethane: Synthesis and Characterization

“…Castor oil is one of the major natural vegetable oils that contain a hydroxyl group and so it is widely used in many chemical industries, especially in the production of PUs [10,11]. The synthesis of PU nanocomposites is prepared from natural oil, like castor oil, using HMDI and organically modified clay and covalently linked PU/n-HMDI composite, which is later collected successfully by the electro spinning process [6].…”

Effects of ambient temperature and injection pressure on biodiesel ignition delay

“…In this study, an RCM equipped with a fuel injector was used to compare the combustion processes of the standard diesel and blended biodiesel fuels. The continuous rise in the cost of fossil fuels as well as environmental pollution has attracted investigations in the area of clean alternative fuels for improving the performance and emissions of internal combustion (IC) engines [16][17][18][19][20][21][22][23]. Biodiesel has been considered to be an alternative fuel to diesel in order to reduce the use of petroleum used.…”
