“…A wide range of plants (more than 300 species) yielding oil seeds can be grown to get both edible and nonedible oils from which biodiesel fuel (BDF) could be produced (Planning Commission of India, 2006;Jain et al, 2011). Employment of edible oils for CI engine units is not encouraged worldwide due to their great demand for human consumption (Banapurmath et al, 2008;No, 2011;Rao, 2011). Serious engine fouling was observed in the CI engine operation due to the incomplete fuel combustion and thereby carbon deposition on the injector tip and valve seat were observed (Mishra and Murthy, 2010).…”

The compression ignition (CI) engines are most efficient and robust but they rely on depleting fossil fuel. Hence there is a speedy need to use alternative fuels that replaces diesel and at the same time engine should yield better performance. Accordingly, honge oil methyl ester (BHO) and cotton seed oil methyl ester (BCO) were selected as an alternative fuel to power CI engine in the study. In the first part, this paper aims to evaluate best fuel injection timing (IT) and injector opening pressure (IOP) for the biodiesel fuels (BDF). The combustion chamber (CC) used for the study is toriodal re-entrant (TRCC). The experimental tests showed that BHO and BCO yielded overall better performance at IT of 19° before top dead centre (bTDC) and IOP of 240 bar. In the second part, the effect of number of holes on the performance of BDF powered CI engine was studied keeping optimized IT and IOP. The six-hole injector with 0.2 mm injector orifice diameter yielded better performance compared to other injectors of different holes and size tested.

“…Numerous researchers reported that the global energy demand will increase progressively, e.g. in 1980, the fuel demand was 6630 million tons of oil in equivalent (Mt), and by 2030, the fuel consumption demand will expected to increase to 53% [3][4][5]. For this reason, the searching for alternative fuels to offset the global demand of fuel consumption becomes more challenging in order to minimize the fossil fuel dependence and subsequently improve the quality of the ecological system.…”

Numerical study on dissimilar guide vane design with SCC piston for air and emulsified biofuel mixing improvement

et al. 2016

Abstract. Crude palm oil (CPO) is one of the most potential biofuels that can be applied in the conventional diesel engines, where the chemical properties of CPO are comparable to diesel fuel. However, its higher viscosity and heavier molecules can contributes to several engine problems such as low atomization during injection, carbon deposit formation, injector clogging, low mixing with air and lower combustion efficiency. An emulsification of biofuel and modifications of few engine critical components have been identified to mitigate the issues. This paper presents the effects of dissimilar guide vane design (GVD) in terms of height variation of 0.25R, 0.3R and 0.35R at the intake manifold with shallow depth re-entrance combustion chamber (SCC) piston application to the incylinder air flow characteristics improvement. The simulation results show that the intake manifold with GVD improved the performance of the air flow characteristic particularly swirl, tumble and cross tumble ratios from the intake manifold to the engine. The GVD with the height of 0.3R was found to be the optimum design with respect to the overall improvement of the air flow characteristic. The improvement of the air flow characteristic with the application of GVD and SCC piston in the engine was expected to contribute to a better air fuel mixing, fuel atomization and combustion efficiency of the engine using emulsified biofuel as a source of fuel.

“…From a list of 75 plant species containing oil in their seeds or kernels more than 30%, 26 species were reported by Azam et al [15] as potential sources of the oil that can be employed for the production of FAMEs suitable for the use as biodiesel. Jatropha curcas crude oil has been used for the biodiesel production [16]. Jatropha is a species of flowering plant in the spurge family, Euphorbiaceaea and it is a droughtresistant tree.…”

Abstract. The use of biodiesel as an alternative fuel is becoming increasingly popular nowadays due to global energy shortage. The interest in using Jatropha as a non-edible oil feedstock is rapidly growing. Biodiesel produced from crude Jatropha oil with NaOH as a catalyst is investigated. Transesterification by methanol is carried out in a closed vessel as a batch system. Factors affecting the process which included the reaction temperature and pressure, reaction time, the molar ratio of methanol to oil and catalyst amount are investigated. The maximum conversion ratio of methyl ester yield of 97.7% was recorded under the conditions of 65 ºC, 1% (by mass) NaOH of the oil mass and 6:1 methanol to oil ratio.
