Karanja Oil

Global warming due to engine exhaust pollution and rapid depletion of petroleum oil reserves, has given us the opportunity to find bio fuels as alternative to diesel fuel. Biodiesel is an oxygenated, sulphur free, non-toxic, biogradable and renewable fuel. Karanja biodiesel is prepared using Karanja oil and methanol by the process of transesterification. In the present study, a military 720 kW turbo charged, compression ignition diesel injection (CIDI) engine was fuelled with diesel and Karanja oil methyl ester (KOME) biodiesel respectively. These were subjected to 100 hours long term endurance tests. The performances of fuels were evaluated in terms of brake horse power (kW), torque, heat release rates and specific fuel consumption. The emission of carbon monoxide (CO), unburnt hydrocarbon (UHC), oxides of nitrogen NOx and smoke opacity with both fuels were also compared. Lubricating oil samples, drawn from the engine after 100 hours long term endurance tests, were subjected to elemental analysis. Atomic absorption spectroscopy (AAS) was done for quantification of various metal debris concentrations. Use of Karanja oil methyl ester (KOME) biodiesel in a turbo charged CIDI engine was found compatible with engine performance along with lower emission characteristics (UHC 70%, CO 85.6%), and exhaust noise 11.9% but 13.7% higher NOx emissions. Engine metals wear were found 32% lower for a KOME biodiesel operated engine.

Recent concerns over the environment, increasing fuel prices and scarcity of its supply have promoted the interest in development of the alternative sources for petroleum fuels. The methyl esters of vegetable oils, known as biodiesel are becoming increasingly popular because of their low environmental impact and potential as a green alternative fuel for diesel engine and they would not require significant modification of existing engine hardware. Methyl ester of Karanja (KME) derived through transesterification process. Experimental investigations have been carried out to examine properties, performance and emissions of different blends ( KB10,KB20, KB30, KB40 and KB50) of KME. However, its diesel blends showed reasonable efficiencies, lower smoke, CO and HC.

Abstract The present work studies the influence of di-tertiary-butyl peroxide (DTBP) as a cetane-improving additive to karanja methyl ester (KME) on the combustion, performance and emission characteristics of a diesel engine. KME produced by base catalyzed transesterification of non-edible karanja oil was blended with DTBP in different volume proportions to result KMED1 (99% KME + 1% DTBP), KMED2 (98% KME + 2% DTBP), KMED3 (97% KME + 3% DTBP) and KMED5 (95% KME + 5% DTBP) fuel blends. With increase in DTBP content, viscosity was reduced, whereas the cold flow properties, cetane index and calorific value were enhanced. Engine test results exhibited improvement in brake thermal efficiency and brake specific energy consumption for all blends compared to neat KME. Combustion analysis showed improved combustion with rise in DTBP content in the blends. The CO, HC and NOx emissions with KME-DTBP blends were less compared to neat KME and the same significantly reduced with rise in DTBP percentage in the blends. This shows improved combustion due to more oxygen availability and improvement in fuel properties with addition of DTBP to KME. However, the NOx emissions were marginally higher with KME-DTBP blends compared to neat KME and diesel that may be further studied.

The performance and emissions from diesel engines are greatly influenced by the degree of atomization of the fuel spray. The characteristics of the spray affect the physics of formation of the air-fuel mixture. They depend on density and viscosity of fuel, injection pressure, pressure and temperature of fuel. The spray structure is primarily dependent on the fuel injection pressure. This study involves the carrying out of experimental investigations on biodiesel and diesel fuel sprays in a DI diesel engine for different injection pressures. The spray cone angle and spray tip penetration length are studied experimentally. Using spray visualization system and image processing techniques, the experimental data is obtained. The fuels used are Karanja oil methyl ester (KOME) and diesel. The experimental results show that, as the injection pressure increases, the spray cone angle decreases for KOME and similar trends are observed with diesel. In addition, spray penetration length increases with increase in injection pressure and the value of the same was slightly higher for KOME than that of diesel. The results also reveal similarities in spray characteristics of both the test fuels.

Active calcium oxide catalyst was synthesised from Meretrix Lyrata (M.Lyrata) following calcination-hydration-dehydration technique. The catalytic feasibility of synthesised CaO was investigated in the production of Karanja methyl ester (KME) from crude Karanja oil (CKO). KME was synthesised through esterification using followed by transesterification utilising CaO in a two-step reaction process of CKO and methanol. The M.Lyrata shells were calcined at 900 ℃ and the catalyst samples were characterised using FTIR, SEM, PSA, and BET-BJH spectrographic techniques. A maximum fatty acid methyl ester (FAME) conversion of 97.3 % was obtained at optimum reaction conditions including methanol-to-oil ratio of 12:1, catalyst concentration of 2 wt.%, reaction temperature of 58 ℃ and reaction time of 2 hrs. In a comparative study with commercial CaO, M.Lyrata showed a higher catalytic activity. The catalyst reusability experiments ascertaining reusability of CaO up to four reuse cycles had shown good efficiency. The economic comparative study confirms that CaO derived from M.Lyrata can be used as an alternative and feasible catalyst for biodiesel production. The KME fuel properties complied to EN-14214 biodiesel fuel standards.
