Abstract The objective of the present work is to find out the viable substitute fuel for diesel and control of pollutants from compression ignition engines. Therefore, in this present investigation an attempt has been made to study the effect of 20% proportion of five different biodiesel diesel blend in diesel engine. The 20% proportion of biodiesel such as Jatropha, Pongamia, Mahua, Annona and Nerium and 80% of diesel and it is denoted as J20, P20, M20, A20 and N20 are used in the present investigation. The experimental results showed that the brake thermal efficiency of the different biodiesel blend is slightly lower when compared to neat diesel fuel. However, N20 blend, have shown improvement in performance and reduction in exhaust emissions than that of other biodiesel diesel blends. From, the experimental work, it is found that biodiesel can be used up to 20% and 80% of diesel engine without any major modification. The conducted experiments were conducted on a four cylinder four stroke DI and turbo charged diesel engine using biodiesel blends of waste oil, rapeseed oil, and corn oil with normal diesel. The peak cylinder pressure of the engine running with bio diesel was slightly higher than that of diesel. The experiments were conducted on a four cylinder four stroke diesel engine using bio diesel made from corn oil.

After the start of mass production in April 2003 of a completely new Euro 4, 1.3 L, common rail Diesel engine, an upgraded variant has been recently developed, with power output increased from 70 to 90 PS and torque output increased from 180 to 200 N·m. To meet this target the combustion system has been deeply revised and common rail pressure increased from 1400 to 1600 bar, while maintaining the multiple injection feature already introduced on the 70 PS variant. Moreover, a variable geometry, small turbocharger has been specifically developed and the mechanical components upgraded to comply with an increased peak cylinder pressure from 140 to 160 bar. In order to comply with Euro 4 emission standards on critical applications with high load factors new control functions have been developed, in order to reduce the dispersion and the drift in durability, such as the lambda control based on an O2 sensor. In spite of Euro 4 emission compliance on most of the forecasted applications with conventional DOC after-treatment, a DPF version will be provided as well, adopting the maintenance free technology already applied on other engines with higher displacement. The 1.3 L SDE family is manufactured in Poland, in a plant located in Bielsko Biala, with an installed production capacity close to 700.000 engines per year.

Demands for more power from the turbocharged diesel, without increase in bulk or weight, has led to an increase in levels of mean effective pressure by the application of high-pressure turbocharging. An investigation was conducted to determine engine performance under high b.m.e.p. conditions and this paper presents results of the experimental part of the research programme. Test work was carried out on a single-cylinder research engine equipped with an independent pressure-charging facility. Boost pressure ratios up to 6.2:1 were used with the geometric compression ratio reduced, in stages, to 8:1, to limit peak cylinder pressure. Power levels up to 35.4 bar b.m.e.p. were produced.

Environmentally friend biodiesel fuel from corn oil was tested in single-cylinder 4-stroke diesel engine operated. Three blends of fuels were prepared from corn oil and diesel fuel viz. 7, 15, and 20 % (designated as B7, B15, and B20, respectively). Tests were conducted on this engine using these blends at a constant speed (1500 rpm) and varying loads (0 % to 100 %). The emissions of carbon monoxide, carbon dioxide, unburned hydrocarbons, nitrogen oxides (NOX) and smoke opacity were measured. In all engine loads, results showed that the emission of CO, HC, and smoke emissions were reduced, while that of NOX and CO2 were increased. Biodiesel blend (B20) showed the highest decrease of the CO and HC and smoke emissions by 22.13 %, 18.5 %, and 25.8 % respectively. While that of NOX and CO2 emissions were increased by 22.3 % and 22%, respectively. It can be recommended as a sound environment friend and renewable for use in diesel engines and can be used without any significant modifications in the engine design.

The focus of this work is to investigate the effect of emulsifier-free emulsion fuel via steam emulsification (SD) to the diesel engine through physical properties, combustion performance, and exhaust analysis, and compare with conventional emulsion fuel with water percentages of 5% and 10% (E5 and E10) and biodiesel blend (B5). The SD was prepared using a custom 200 mL glass mixing column. The B5 fuel quantitatively was filled in the column, and then the steam was injected from the bottom of the mixing column through the porous frit glass with the pores ranging from 40 to 100 µm. The average water droplet size of SD is 0.375 µm with the average water percentage of 6.18%. The brake specific fuel consumption (BSFC) and brake thermal efficiency (BTE) of SD improved 4.19% and 3.92%, respectively, as compared to B5. The in-cylinder pressure (ICP) was lower than B5, however, yielding close to the B5 at 4 kW engine load. As for the exhaust emission test, NOx and PM for SD were reduced significantly with a percentage reduction of 25.22% and 10.68%, respectively, as compared to neat B5. The steam emulsification method offers a huge potential to be explored further as the concept offers the alternative method of making emulsion fuel without the use of conventional mechanical mixers.

An algorithm for determining the four tuning parameters in a double-Wiebe description of the combustion process in spark-assisted compression ignition engines is presented where the novelty is that the tuning problem is posed as a weighted linear least-squares problem. The approach is applied and shown to describe well an extensive data set from a light-duty gasoline engine for various engine speeds and loads. Correlations are suggested for the four parameters based on the results, which illustrates how the double-Wiebe approach can also be utilized in a predictive simulation. The effectiveness of the methodology is quantified by the accuracy for describing and predicting the heat release rate and predicting the cylinder pressure. The root-mean square errors between the measured and predicted cylinder pressures are 1bar or less, which corresponds to 2% or less of the peak cylinder pressure.

Performance, emission and combustion studies were carried out on the ceramic coated diesel engine (YSZ) fed with biodiesel obtained from the oil derived from the mango seeds (MSBD) and MSBD blended with turpentine oil (MSBTO). The performance study showed that the MSBD and MSBTO blends showed 3.6% and 7.1% more BSFC value compared to that of DF in ceramic coated engine due to higher density and viscosity. The maximum brake thermal efficiency was observed 28% for DF in coated engine compared to other fuels due to less fuel consumption of DF because of lower density. The emission characteristics displayed that the MSBTO fuel showed 12%, 15.2% and 29.1% reduction in the smoke density, NOx and CO respectively compared to that of DF in coated engine. However, the MSBD and MSBTO showed 17 and 21% more release of UBHC at full conditions compared to that of DF in ceramic coated engine due to lesser calorific values of MSBD and MSBTO compared to the calorific value of DF. Combustion study revealed that the MSBD and MSBTO displayed less cylinder pressure compared to that of DF in coated engine and the MSBTO fuel showed the 5.3% decrease in the cylinder pressure compared to that of DF in coated engine owing to less heat liberation and lower cetane value. HRR followed the similar trend of variation of cylinder pressure and the MSBTO displayed 7.4% lower HRR compared to that of DF in coated engine.

The aim of the present work is to investigate the possibility of using eucalyptus biodiesel and its blends with diesel fuel as an alternative fuel for diesel engines. Eucalyptus oil is converted to biodiesel with ethanol using sodium hydroxide as a catalyst. The characterization of the obtained biodiesel shows that the thermo-physical properties are in the range recommended by American Standard (ASTM D6751). Innovative biodiesel development tests on the diesel engine require a lot of time and efforts. Here, mathematical model, which is based on the thermodynamic single zone model, is developed to analyze the combustion characteristics such as cylinder pressure and the performance characteristics such as brake power, brake thermal efficiency and specific fuel consumption of a DI diesel engine.
