“…The test results indicated a reduction in ignition latency and soot emissions. With the addition of the nano adjuvant, the oxidation rate increased. − Moreover, another researcher investigated a diesel engine’s performance and exhaust emission employing Jatropha methyl ester emulsions using alumina nanoparticles and carbon nanotubes as an additive. The results indicated an increase in the thermal efficiency of the brakes and a decrease in exhaust gases. − …”

This work reviews the numerous key parameters of each alcohol and their effect on CI engine characteristics. The second part of the review emphasizes the effect of nanoadditive addition on diesel and biodiesel owing to their physical and chemical features. A more detailed evaluation of the influence of nanoadditives on diesel engine behavior was done when diesel and biodiesel were doped at varying doses. According to the review, alcohols with a greater carbon concentration, such as butanol and pentanol, have superior miscibility and stability versus alcohols with lesser carbon elements. Additionally, the lower cooling impact and autoignition capability generated by high-alcohol concentrations would make this the optimum additive formulation for usage with diesel fuel. Nanoparticles have been added to fuels used in diesel engines to improve performance and reduce emissions in recent years. The utilization and preparation of fossil-based fuels increase environmental-related issues. Different nanomaterials assorted with fuels for compression ignition (CI) engines and their effects are reviewed in this work. Nanomaterials added to pure diesel and blends of diesel and biodiesel are considered for the study. The physiochemical properties of different fuels with nanoadditives are summarized. Performance characteristics such as brake-specific fuel consumption (BSFC), brake thermal efficiency (BTE), and exhaust gas temperature (EGT) are analyzed and compared for various fuel and nanoadditives combinations. Combustion characteristics and mass fraction burned are investigated. The values of various emissions from the engines fuelled with different combinations are examined. Among the various fuels and nanoadditives studied, 100 ppm TiO2 added diesel consumes the lowest BSFC of 0.3 kg/kWh. Hurdles faced in the current utilization of nanoadditives in diesel engines and the scope for future research are also highlighted.

“…It can be seen that contributions of combustion process towards noise emissions occurs at wider frequency bands when compared with cylinder pressure PSD plots. This may be due to several non-linear paths of noise propagation through engine as discussed in [7][8][9][10][11][12][13][14][15][16][17]. Noise PSD plots were characterized by high frequency components that may be due to several other contributing sources.…”

The health monitoring has been studied to ensure integrity of design of engine structure by detection, quantification, and prediction of damages. Early detection of faults may allow the downtime of maintenance to be rescheduled, thus preventing sudden shutdown of machines. In cylinder pressure developed, vibrations and noise emissions data provide a rich source of information about condition of engines. Monitoring of vibrations and noise emissions are novel non-intrusive methodologies for which positioning of various transducers are important issue. The presented work shows applicability of these diagnosis methodologies adopted in case of diesel engines. The effects of changing various fuel injection parameters was analyzed. Scope of using non-intrusive technique has been analyzed by changing locations of microphone. Novelty of this worklies in exploring signal processing methods for various locations around the engine test set up. Various frequency ranges of contributing noise and vibration sources were identified. Time-Frequency analysis showed the onset of various cyclic. Based on the identification of various frequency bands, it is possible to device suitable filters in order to extract more information.

“…28 TiO 2 is one of the best inhibitors, catalysts, and additives, which are more efficient than others since they have a larger surface area available to react with other molecules when added to diesel fuel. 29 Moreover, it is important to mention that the TiO 2 pollution for the environment can be negligible at this experimental work due to minor usage in the diesel fuel. Because of this, titanium dioxide was taken for this examination.…”

In this study, the operation of a four-cylinder, four-stroke DI diesel engine powered by fuels created by blending diesel and TiO 2 nanoparticles was evaluated based on energy and exergy analyses. Within the study's scope, it is possible to see the engine's performance, combustion, emission, and heat transfer distribution at various engine speeds. The engine was tested by operating it with diesel and fuel blends, diesel-2.5 ppm TiO 2 . According to obtained results, it was found that by adding 2.5 ppm TiO 2 to diesel fuel, energy and exergy efficiency increased by 4.1% and 3%.Engine power and shaft exergy improved by 3.4%, and diesel-2.5 ppm TiO 2 blends decreased irreversibility by 3.8%. Diesel-2.5 ppm TiO 2 blended fuel decreases the exhaust loss exergy and exhaust heat losses by 2.5% and 1.4% and also uncounted heat losses reduced by 5.7% compared with baseline diesel. Moreover, the exergy transfer with cooling water increased by 10.5% compared with baseline diesel fuel.The brake specific fuel consumption was 3% lower for diesel and 2.5 ppm TiO 2 nanoparticle blended fuels. The engine fueled with blended fuel revealed mitigation in the UHC, CO, and Soot emissions than those of diesel fuel. NOx emission exhibited increasing trends with the blended fuel. It is concluded that diesel blend with the addition of TiO 2 nanoparticles exhibits better engine performance and reduced emissions compared to diesel fuel.diesel engine, diesel fuel, engine characteristics, exergy-energy analysis, TiO 2 nanoparticle | INTRODUCTIONRecently, due to the environmental deterioration, global energy crisis, and sustainable development, diesel engines have faced the careful regulation prescriptions ratified on limiting the peril outflowed from the combustion of engines. 1,2 A feasible method is to substitute the fuels with various physiochemical properties and cleaner combustion concerning the environment. 3 Ethanol as a generally available fuel could be used either as a pure substitution or in a mixture form. 4,5 It is also considered in terms of renewable and alternative energy, which also needs less oxygen to get burned compared with baseline diesel fuel. 6,7 Recently, among many options, nano-technology has got great attention on the fuel synthesis of automotive engines. During the combustion, due to augmentation in the ratio of the surface area per volume, nanoparticles with catalytic and oxidation properties improve the thermal performance and curtail emissions. 8 Recently, many investigations have observed the impact of adding nanoparticles to pure fuel or mixture fuel on combustion. For instance, Mardi et al. 9 investigated the effect of blended Ethanol-Methanol-Butanol fuels with CNT, Al2O3, and TiO2 nano additives on the diesel engine. They reported notable improvement in each aspect of performance, such as improved brake power (BP) and brake thermal efficiency (BTE) along with the brake specific fuel consumption (BSFC) reduction. Moreover, they showed a significant reduction in all emissions CO, UHC, NOx, and smoke, using na...
