“…Due to delayed injection timing, multiple injection procedures were more effective in mitigating the release of soot and NO x throughout the combustion process. Still, such strategies may not be cost-effective or easy to implement. − Nour et al investigated the impacts of methanol and diesel blends. Methanol fuel’s BSFC and NO x emissions were higher, whereas conventional diesel fuel’s brake thermal efficiency (BTE) and CO and HC emissions were reduced.…”

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.

“…Cost savings from using hydrous ethanol as an engine fuel were found to be reasonable. 26 Four-part loads and three fuel injection pressures were evaluated with a blend of 80% diesel and 20% biodiesel made from waste cooking oil. According to the test results, opacity (84.4%), HC (71.8%), and CO (46.8%) were significantly decreased as compared to the basic diesel operating at a single injection and a lower fuel injection pressure.…”

Biofuels are regarded as the best diesel fuel substitute due to their low sulfur concentration, reduced aromatic hydrocarbon content, renewable nature, and higher oxygen content. In this research article, the impact of producer gas, Calophyllum inophyllum oil, diesel, and a blend of C. inophyllum–producer gas fuel on a variable compression ratio (VCR) compression ignition (CI) engine, and the performance and emission parameters are evaluated. Several test runs are undertaken at a constant speed of 1500 rpm to predict the performance and emission characteristics of the test engine by changing input parameters such as engine load, CR, and fuel mode of operation. The brake thermal efficiency, BTE, is considered the performance characteristic, and CO, HC, NO X , and opacity are considered the emission characteristics for the present study. The biofuel, or producer gas, employed in this study is prepared from waste biomasses, such as leaves, small tree branches, vegetable waste, and cow dung, aiding waste management for a sustainable environment. In addition, a coupled Taguchi–Grey relational analysis technique is used to predict the best possible combination of control factors for optimizing the overall output responses. 12 kg load, a CR of 18, and diesel fuel are found to be the optimum input parameters of an engine toward optimum performance. A confirmation test is performed at the end to validate the outcome of the experiment. An enhancement in performance of 22.75% is observed with the considered Grey relational grade model.

This research aims to utilize the energy available from fish canning waste (FCW) as a partial alternative. The fuel is chemically modified to fish canning waste methyl ester (FCWME) by acid‐catalytic transesterification process and blended with diesel at 10%, 20% and 30% volume. The engine utilized in this study is slightly modified by engaging exhaust gas recirculation (EGR) to lower the nitrous oxide (NO) emission of oxygen‐rich fuel blends. Performance tests demonstrated that the FCW/diesel blends show similar patterns to diesel. Higher fuel consumption of 0.01, 0.03 and 0.04 kg/kWh was noted by including FCWME by 10%, 20% and 30% by volume. Power losses of about 1.4%, 1.9% and 2.1% were experienced by blending 10%, 20% and 30% volumes of FCWME with diesel. Conversely, the tailpipe emissions, namely smoke, CO and HC emissions, lowered by 3.7%, 0.017% and 21 ppm, with 117 ppm elevated NO emissions for the FCWME/diesel blends than diesel. The test results revealed that the NO emissions from all test fuels lowered drastically during 10%–30% EGR; 91 ppm reduction in NO emissions was observed at a 30% EGR rate, with a slight increase in other regulated emissions. Considering the encouraging impacts on the environment and improved fuel combustion pattern, FCW biofuel shall be employed as a likely and fractional alternative to diesel fuel.
