This paper emphasizes on the effects of different biodiesels and diesel on; heat release, ignition delay, endothermic and exothermic reactions, NOx, fuel injection pressure due to the fuel’s modulus of elasticity and cylinder pressure. Two 100% biodiesel and its blends of 20% with of low sulfur #2 diesel, and #2 diesel are tested on a single cylinder diesel engine under full load condition. Engine performance and emissions data is obtained for 100% and 20% biodiesels blends and #2 diesel. Testes were conducted at Engine Systems Development Centre, Inc. (ESDC) to evaluate the effects of biodiesel and its blends on the performance and emissions of a single-cylinder medium-speed diesel engine. The main objective of this work was to gain initial information and experience about biodiesel for railway application based on which biodiesel and its blends could be recommended for further investigation on actual locomotives.

AbstractIn recent years, engine emissions have been one of the important problems which are of great concern. Hence, there is a growing need to develop engines with reduced emission. In the present study, Variable Compression Ratio diesel engine model has been validated by comparing the simulation results with the experimental. The study is aimed at analyzing the effect of compression ratio, exhaust gas recirculation, fuel injection pressure and start of injection on engine performance and emission characteristics. Using composite desirability technique, the engine parameters have been optimized to achieve lower NOx, soot and ISFC. The optimum combination has been observed at Compression ratio 17.52, Start of injection −30.1 °aTDC, Fuel injection pressure 736.06 bar and Exhaust gas recirculation 28.29%. ISFC, NOx and soot are reduced by 2.37%, 29.11% and 83.81% respectively. Higher Target Fuel Distribution Index indicates the improved mixture homogeneity for the optimized parameters.

Alternative fuels are in demand to overcome limitations of fossil fuels since decades. Indian Standards of biodiesel exists and its wide application is appealed and a National Policy on Bio fuels was implemented by Ministry of New and Renewable Energy. This Paper presents a review of biodiesel, Indian standards and difference of ASTM/EN for biodiesel. Biodiesel and its different blend fuelled in Diesel engine exhibit different engine performance and exhaust gas emission characteristics. Various performance parameters affects compression ignition diesel engine (DI-CI) performance, list includes fuel injection pressure, fuel quantity injected and injection timing, shape of combustion chamber, position and size of injection nozzle hole, fuel spray pattern, etc. Few paramount factors governing DI-CI engine includes various types of biodiesel and its blending with diesel engine. Types of blending are namely mahua, jatropha, karanja, waste cooking oil etc. Authors have blended them with varying percentage with varying fuel injection pressure at different loads. Few have also used alumina as nano additives in mahua biodiesel (B25100Al2O3) to check it effects on performance parameters as well as on emission characteristics. Effect of blending with Karanja, Jatropha, Neem , mahua etc as biodiesel with inclusion of alumina as nano additives are reviewed for related performance parameters (i.e. brake thermal efficiency (BTE), brake specific fuel consumption (BSFC)) and emission characteristics (i.e. CO, HC, NOx) in exhaust gas emission in different conditions for DI-CI Engine performance.

Engine Performance And Emissions

An experimental investigation has been carried out to compare the performance and emissions of a low-compression-ratio Euro 5 diesel engine featuring high EGR rates, equipped with different injector technologies, i.e., solenoid, indirect-acting, and direct-acting piezoelectric. The comparisons, performed with reference to a state-of-the-art double fuel injection calibration, i.e., pilot-Main (pM), are presented in terms of engine-out exhaust emissions, combustion noise (CN), and fuel consumption, at low–medium engine speeds and loads. The differences in engine performance and emissions of the solenoidal, indirect-acting, and direct-acting piezoelectric injector setups have been found on the basis of experimental results to mainly depend on the specific features of their hydraulic circuits rather than on the considered injector driving system.
