Performance And Emission

This paper presents a comparative analysis of the diesel engine performance and emission characteristics, when operating on diesel fuel and various diesel-biodiesel (B10, B20, B40, B60) blends, at various loads and engine speeds. The experimental tests were performed on a four-stroke, four-cylinder, direct injection, naturally aspirated, 60 kW diesel engine D-243. The in-cylinder pressure data was analysed to determine the ignition delay, the Heat Release Rate (HRR), maximum in-cylinder pressure and maximum pressure gradients. The influence of diesel-biodiesel blends on the Brake Specific Fuel Consumption (bsfc) and exhaust emissions was also investigated. The bench test results showed that when the engine running on blends B60 at full engine load and rated speed, the autoignition delay was 13.5% longer, in comparison with mineral diesel. Maximum cylinder pressure decreased about 1–2% when the amount of Rapeseed Methyl Ester (RME) expanded in the diesel fuel when operating at full load and 1400 min–1 speed. At rated mode, the minimum bsfc increased, when operating on biofuel blends compared to mineral diesel. The maximum brake thermal efficiency sustained at the levels from 0.3% to 6.5% lower in comparison with mineral diesel operating at full (100%) load. When the engine was running at maximum torque mode using diesel – RME fuel blends B10, B20, B40 and B60 the total emissions of nitrogen oxides decreased. At full and moderate load, the emission of carbon monoxide significantly raised as the amount of RME in fuel increased.

A multizone combustion model for closed cycle of a DI diesel engine is developed to interpret the experimental investigations on the utilization of diesel-ethanol-biodiesel blends of high ethanol fraction (DEB blends). A computer-based programming for engine process simulation is developed in MATLAB. The model is validated with the experimental values of cylinder pressure and heat release rate. Important information related to fuel injection and combustion inside the combustion chamber, is revealed through the model prediction which is normally difficult to get from the experiments. Model prediction shows that the rate of fuel evaporation is higher for DEB blends, than diesel fuel at any instant of time. The fuel combustion is started late for DEB blends compared to diesel fuel, however, once the combustion is started the burning rate is higher than the diesel fuel. The droplet size (Sauter mean diameter) is decreased for DEB blends which indicate improved fuel atomization. The mean temperature in the zone is significantly lower for DEB blends compared to diesel fuel. The equivalence ratio in the zone is decreased for DEB blends proving that engine runs leaner. The equivalence ratio trend is not uniform as it depends on the combination of the rate of fuel evaporation, rate of air entrainment and rate of burning. Soot density is remarkably decreased, and NOx formation is also drastically reduced for DEB blends at different instant of time. The predictions help to interpret the experimental results for DEB blends and its comparison with diesel fuel.

The Impact

Engine injection strategy and renewable fuel both can improve nitrogen oxides (NOX) and smoke/soot emissions in a common-rail compression ignition (CI) diesel engine. The effects of different postinjection (PI) timings (15, 30, and 45) after top dead center (aTDC) and injection pressures (550 and 650 bar) on pollutant emissions and smoke/soot emissions were investigated for combustion of a renewable fuel (soybean biodiesel). The results showed that the levels of carbon monoxide (CO), hydrocarbons (HCs), and NOX are reduced from the combustion of soybean biodiesel compared to the diesel fuel combustion for different injection strategy. Besides, NOX emission is clearly reduced with retarded PI timing, especially at 45°. It is found that the increasing injection pressure reduced gaseous emissions for both fuels. The combination between biodiesel fuel and injection strategy can provide meaningful improvements in pollutant emissions, as well as enhance the exhaust temperature compared to the diesel fuel. With biodiesel fueling, smoke/soot emissions were reduced from biodiesel combustion (by 19.7%) under different fuel injection timings and pressures rather than from the diesel fuel combustion (by 12.2%).

Diesel engines are widely used for their low fuel consumption and better efficiency. Fuel conservation, efficiency and emission control are always the investigation points in the view of researchers in developing energy system. India to search for a suitable environmental friendly alternative to diesel fuel. The regulated emissions from diesel engines are carbon monoxide (CO), Hydrocarbons (HC), NOx and Particulate matter. It creates cancer, lungs problems, headaches and physical and mental problems of human. This paper focuses on the substitution of fossil fuel diesel with renewable alternatives fuel such as Biodiesel. Biodiesel is much clear than fossil diesel fuel and it can be used in any diesel engine without major modification. The experiment was conducted in a single-cylinder four-stroke water-cooled 3.4 kW direct injection compression ignition engine fueled with non-edible Pungamia oil biodiesel blends. The experimental results proved that up to 40% of Pungamia oil biodiesel blends give better results compared to diesel fuel. The AVL 444 di-gas analyzer and AVL 437 smoke meter are used to measure the exhaust emissions from the engine. The observation of results, non-edible Pongamia biodiesel blended fuels brake thermal efficiency (3.59%) is improved and harmful emissions like CO, unburned HC, CO2, Particulate matter, soot particles, NOx and smoke levels are 29.67%, 26.65%, 33.47%, 39.57%, +/- 3.5 and 41.03% is decreased respectively compared to the diesel fuel. This is due to biodiesel contains the inbuilt oxygen content, ignition quality, carbon burns fully, less sulphur content, no aromatics, complete CO2 cycle.

The paper highlights the results of an experimental investigation carried out on Karanja oil as a supplementary for diesel fuel in Compression Ignition engine. In the present study, triglycerides of Karanja oil is converted into mono-ester (biodiesel) using based catalyst transesterfication process. Karanja biodiesel is blended with petroleum diesel in the volumetric proportions of 2−10%. Results reveal that the performance characteristics of Karanja biodiesel blends are well comparable with diesel fuel. The emission characteristics such as CO, HC and smoke are found to be lower for Karanja biodiesel blends at all the engine load conditions compared to diesel fuel. Hence, it is concluded that Karanja oil at lower blends can be used in diesel engine without any substantial engine modification.
