In current years, many researches have been worked to find new sources of alternative fuels. In this situation, the water hyacinth will be a new source for bioethanol. In this study, bioethanol extracted from water hyacinth is blended with diesel (5-BED, 5% bioethanol and 95% diesel v/v) and has been used to experimentally investigate the diesel engine performance and emission. The response surface methodology (RSM) technique with three engine operating variables like (i) Load, (ii) Compression ratio (CR) and (iii) Fuel Injection pressure (FIP) has been implemented to evaluate diesel engine performance using bioethanol diesel blend. The equations were obtained for Brake power (BP), Brake mean effective pressure (BMEP), Brake thermal efficiency (BTHE), and NO emission by using quadratic polynomial

Performance And Emission

The exhaustive and irresponsible use of fossil fuels has created numerous public and environmental health issues in the past few decades. To address this issue, this work has investigated the use of polanga ( Calophyllum inophyllum) biodiesel/diesel blends in a diesel engine. This study focuses primarily on the optimization of performance and emission characteristics of a diesel engine fuelled with polanga-based biodiesel blends. The engine input factors were also investigated for desired optimal thermal performance. In this study, four input parameters, namely, engine loads, blends of polanga-based biodiesel, fuel injection pressure, and fuel injection timing were chosen for analysis. The corresponding engine output responses, namely, brake thermal efficiency, CO, NOx, and smoke emissions, are selected for their optimization by Taguchi method and response surface methodology. The results show that the best setting of above-mentioned input factors is reported at 44% engine load, 13% mixing of polanga biodiesel with diesel, 180 bar injection pressure of fuel, and 21.5 °bTDC injection timing of fuel. The comparison between results obtained by the optimization process and experimental results showed that the deviations were always found to be within the acceptable range of errors.

An experimental investigation was conducted to evaluate the suitability of hazelnut oil methyl ester (HOME) for engine performance and exhaust emissions responses of a turbocharged direct injection (TDI) diesel engine. HOME was tested at full load with various engine speeds by changing fuel injection timing (12, 15, and 18 deg CA) in a TDI diesel engine. Response surface methodology (RSM) and least-squares support vector machine (LSSVM) were used for modeling the relations between the engine performance and exhaust emission parameters, which are the measured responses and factors such as fuel injection timing (t) and engine speed (n) parameters as the controllable input variables. For this purpose, RSM and LSSVM models from experimental results were constructed for each response, namely, brake power, brake-specific fuel consumption (BSFC), brake thermal efficiency (BTE), exhaust gas temperature (EGT), oxides of nitrogen (NOx), carbon dioxide (CO2), carbon monoxide (CO), and smoke opacity (N), which are affected by the factors t and n. The results of RSM and LSSVM were compared with the observed experimental results. These results showed that RSM and LSSVM were effective modeling methods with high accuracy for these types of cases. Also, the prediction performance of LSSVM was slightly better than that of RSM.

Biodiesel such as linseed oil can be derived from the feedstock of vegetables without disturbing supplies of food and the ecosystem. An experimental and comparative analysis was carried out to explore the effect of exhaust gas recirculation (EGR) and fuel injection pressure (FIP) on the emissions and efficiency of a CRDI diesel engine fuelled with linseed biodiesel/diesel blend. The engine characteristics were calculated using variable EGR (up to 14%) and adjustment of the injection pressure (up to 600 bar) under various load conditions. Multiple regression models were generated to evaluate responses such as Carbon monoxide (CO), Oxides of Nitrogen (NOx), hydrocarbon (HC), Brake power (BP), and Brake thermal efficiency (BTE) using response surface methodology (RSM). For all blends, a combination of FIP and EGR was employed and their impact was evaluated by plotting response surface contour. In RSM, the desirability approach is used to maximize the performance and minimize the emissions parameters of the engine. Linseed/diesel blend ratio 18.3%, FIP 576.76 bar, EGR 7.07%, and load 5.76 kg were estimated to be optimum for the tested engine. From this methodology, it was found that the optimal value of BTE, BP, HC, NOx, and CO is 19.55%, 1.758 kW, 16.7534 ppm, 505.56 ppm, and 0.0676% respectively.

The rapid consumption of crude oil and resulting pollution are very severe problems in modern energy sectors. To meet these global problems, biodiesels obtained from non-edible plants can play a very crucial role. Keeping this idea in mind the present study focuses on making some efforts for the best utilization of innovative blends of Prosopis juliflora biodiesel in the operation of diesel engines. Four engine input parameters viz. fuel injection pressure (16–24 MPa), P. Juliflora biodiesel blends (0–10%), shaft loads (20–100%) and injection timing (15–31°bTDC (before top dead centre)) are selected for optimization process. The experiments were executed in accordance with response surface methodology. The results of the experiments revealed that the optimum combination for engine input parameters were at fuel injection timing 30°bTDC, fuel injection pressure 22 MPa, 4% P. juliflora biodiesel blending at 59% of engine load to achieve best performance. The individual desirability of brake thermal efficiency, brake specific fuel consumption, exhaust gas temperature and peak cylinder pressure were found to be 0.888, 0.949, 0.624 and 0.749, respectively, and the composite desirability of engine responses was found to be 0.7923 which makes the results acceptable.

The use of fossil fuel is increasing drastically due to its consumption in all consumer activities. The utility of fossil fuel depleted its existence, degraded the environment and led to reduction in underground carbon resources. Hence the search for alternative fuels is paying attention for making sustainable development, energy conservation, efficiency and environmental preservation. The worldwide reduction of underground carbon resources can be substituted by the bio-fuels. The researchers around the world are finding the alternate fuel that should have the least impact on the environment degradation. This paper aims at finding an alternative for diesel and reducing the pressure on its existing demand. This study aimed at using two types of oil mixtures namely cashew nut shell oil and camphor oil mixed with diesel, turpentine oil mixed with diesel in different proportions as fuel in twin cylinder four stroke diesel engine. Performance and emission analysis have been performed by using exhaust gas analyzer in the oil samples. It was observed that 40% cashew nut shell oil and 10%camphor oil mixed with 50% diesel, 50% turpentine oil mixed with 50% diesel shows the better engine performance and also less emissions.

Performance And Emission

For economic and social development of any country energy is one of the most essential requirements. Continuously increasing price of crude petroleum fuels in the present days coupled with alarming emissions and stringent emission regulations has led to growing attention towards use of alternative fuels like vegetable oils, alcoholic and gaseous fuels for diesel engine applications. Use of such fuels can ease the burden on the economy by curtailing the fuel imports. Diesel engines are highly efficient and the main problems associated with them is their high smoke and NOx emissions.  Hence there is an urgent need to promote the use of alternative fuels in place of high speed diesel (HSD) as substitute. India has a large agriculture base that can be used as a feed stock to obtain newer fuel which is renewable and sustainable. Accordingly Uppage oil methyl ester (UOME) biodiesel was selected as an alternative fuel. Use of biodiesels in diesel engines fitted with mechanical fuel injection systems has limitation on the injector opening pressure (300 bar). CRDI system can overcome this drawback by injecting fuel at very high pressures (1500-2500 bar) and is most suitable for biodiesel fuels which are high viscous. This paper presents the performance and emission characteristics of a CRDI diesel engine fuelled with UOME biodiesel at different injection timings and injection pressures. From the experimental evidence it was revealed that UOME biodiesel yielded overall better performance with reduced emissions at retarded injection timing of -10° BTDC in CRDI mode of engine operation.
