Diesel fuel is necessary for farming, transport, and industrialized sector. It contributes to the wealth of the universal economy while it is widely used due to having higher flexibility, combustion efficiency, consistency and handling facilities. However, emissions from fossil fuel are considered as the main source of environmental pollution. Thus, it becomes necessary to reduce emission by improving the performance of the engines. Recently the addition of catalytic material like nanoparticles to diesel proves to be a hopeful solution to reduce emission without much modification of the existing engine design. In the present study, the influence of nanoparticles doped with diesel on the performance and emission characteristics are carried out in a naturally aspirated, single-cylinder, four-stroke, water-cooled, 3.7 kW, direct-injection compression-ignition engine is coupled with eddy current dynamometer and high-speed data acquisition system. Cerium Oxide nanoparticles are selected as the best oxygen boosting catalytic nanoparticle and it is prepared by the sol-gel process.  Nanoparticles, then doped with diesel with the help of an Ultrasonicator with different molar concentrations (5 ppm, 7.5 ppm, 10 ppm, 15 ppm). Fuel properties of nano doped fuel samples are tested and presented in this paper. The DI CI engine experimental results were found to be brake thermal efficiency is increased by 3.6% by simultaneously reducing fuel consumption by 3.63% and also harmful environmental pollution like carbon monoxide, unburned hydrocarbon, carbon dioxide, and smoke level are decreased by 9.11%, 6.3%, 3.12%, and 12.6% respectively compared to pure diesel. It may be due to the enhanced surface to volume ratio, catalytic activity and improving the mixing rate of fuel and air in the combustion chamber.

Performance And Emission

The objective of this project was to develop both engine performance and emission profiles for two test fuels — a 6% water-in-diesel oil emulsion (DOE-6) fuel and a neat diesel (D100) fuel. The testing was performed on a single cylinder, direct-injection, water-cooled diesel engine coupled to an eddy current dynamometer. Output parameters of the engine were used to calculate Brake Specific Fuel Consumption (BSFC) and Engine Efficiency (η) for each test fuel. DOE-6 fuels generated a 24% reduction in NOX and a 42% reduction in Carbon Monoxide emissions over the tested operating conditions. DOE-6 fuels presented higher ignition delays — between 1°-4°, yielded 1%–12% lower peak cylinder pressures and produced up to 5.5% lower exhaust temperatures. Brake Specific Fuel consumption increased by 6.6% for the DOE-6 fuels as compared to the D100 fuels. This project is the first research done by a New Zealand academic institution on water-in-diesel emulsion fuels.

This paper investigates the performance and emission characteristics of 20% cashew nut shell liquid (CNSL)-diesel blend (B20) in a direct injection diesel engine. The cashew nut shell liquid was prepared by pyrolysis method. The test was conducted with various nozzle opening pressures like 200 bar, 225 bar and 250 bar at different loads between no load to full load. The results showed that the brake thermal efficiency was increased by 2.54% for B20 with 225 bar at full load. The CO and smoke emissions were decreased by 50% and 14% respectively and the NOx emission were decreased slightly with 225 bar injection pressure compared with 200 bar and 250 bar at full load. On the whole, it is concluded that the B20 CNSL blend can be effectively used as a fuel for diesel engine with 225 bar injection pressure without any modifications.

Analysis Of Performance

A computational study on performance and exhaust emissions from a 4-stroke DI CI engine using different air induction methods was carried out. Using AVL Boost IC engine simulation software a model was developed with a Naturally Aspirated (NA) air induction mode, the second model was developed by incorporating a turbocharger (TC) and again a third model was developed by the introduction of a turbocharger along with an intercooler (TCI). The individual effects of all the three air induction methods on the performance and emission of engine were studied and compared. The power output for the engine with TCI was observed to be 7.8% more than that of an engine with TC, where as it was even greater i-e 20% more when compared with NA engine. Similar Improved results for torque were also observed in case of an engine with TCI. It was also observed that emissions were higher with TCI followed with TC and NA.

A dual-fuel engine is a compression ignition (CI) engine where the primary gaseous fuel source is premixed with air as it enters the combustion chamber. This homogenous mixture is ignited by a small quantity of diesel, the ‘pilot’, that is injected towards the end of the compression stroke. In the present study, a direct-injection CI engine, was fuelled with three different gaseous fuels: methane, propane, and butane. The engine performance at various gaseous concentrations was recorded at 1500 r/min and quarter, half, and three-quarters relative to full a load of 18.7 kW. In order to investigate the combustion performance, a novel three-zone heat release rate analysis was applied to the data. The resulting heat release rate data are used to aid understanding of the performance characteristics of the engine in dual-fuel mode. Data are presented for the heat release rates, effects of engine load and speed, brake specific energy consumption of the engine, and combustion phasing of the three different primary gaseous fuels. Methane permitted the maximum energy substitution, relative to diesel, and yielded the most significant reductions in CO2. However, propane also had significant reductions in CO2 but had an increased diffusional combustion stage which may lend itself to the modern high-speed direct-injection engine.

In this study an experimental investigation has been carried out on compression ignition engine to understand the engine behaviour like its performance and emission characteristics while using Aluminium oxide (Al2O3) nano particle as additive with a blend of diesel and biodiesel sourced from Jatropha and Pongamia vegetable oil. The Alumina nano particles are characterized by X- ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) analysis. The biodiesel is made engine ready with adoptable properties by carrying out standard alkali transesterification process. The alumina nano particles are blended with jatropha in the mass fractions of 50, 100, 150 ppm and with Pongamia biodiesel in the mass fractions of 40, 60 ppm using an ultrasonicator. The experiments are carried out in single cylinder four stroke variable compression ratio diesel engine by varying the load using eddy current dynamometer. The experimental results reveal that there is a significant improvement in the performance characteristics like brake thermal efficiency (BTHE) and brake specific fuel consumption (BSFC) and reduction in the emission constituents like carbon monoxide (CO) and unburned hydrocarbon (HC) but in turn increase in nitric oxide (NOx) emissions were observed.
