The use of liquefied petroleum gas (LPG) is experimented with to improve the performance of a dual fuel compression ignition (CI) engine running on Karanja oil methyl ester (KOME) blends. Diesel is used as a reference fuel for the dual fuel engine results. During the experimentation, the engine performance is measured in terms of brake thermal efficiency (BTE) and brake specific fuel consumption (BSFC), and exhaust emission is measured in terms of carbon monoxide (CO), hydrocarbon (HC), and oxides of nitrogen (). Dual fuel engine with LPG showed a reduction in and smoke emission; however, it suffers from high HC and CO emission, particularly, at lower loads due to poor ignition. Comparison of performance and emissions is done for diesel and blends of KOME. Results showed that using KOME blends (10% and 20%) has improved the CI engine performance with a reduction in HC and CO emissions.

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.

Abstract This paper depicts Box-Behnken design (BBD) approach to optimize the performance and emission characteristics of adjustable compression ratio, single- cylinder diesel engine with nanoparticle-blended biofuel. Cerium oxide (CeO2) nanoparticles and diethyl ether (DEE) are mixed with neem methyl ester (NME) in corresponding ratios as per BBD experimental plan. Engine performance characteristics brake thermal efficiency (BTE), brake-specific fuel consumption (BSFC), and NOx, CO, HC, and CO2 emissions have been analyzed. To study the influence of input parameters, quadratic models are developed on each output response using analysis of variance (ANOVA). Desirability function approach has been used to optimize the performance of multi-response parameters. The results revealed that nanoparticles mixed blends of NME and DEE enhances the performance characteristics and reduce the harmful emissions.

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.

Engine performances and emission characteristics of Karanja oil methyl ester blended with diesel were carried out on a variable compression diesel engine. In order to search for the optimal process response through a limited number of experiment runs, application of Taguchi method in combination with grey relational analysis had been applied for solving a multiple response optimization problem. Using grey relational grade and signal-to-noise ratio as a performance index, a particular combination of input parameters was predicted so as to achieve optimum response characteristics. It was observed that a blend of fifty percent was most suitable for use in a diesel engine without significantly affecting the engine performance and emissions characteristics.
