Carbon emission and problems associated with the world have been the major concerns for the past few decades. The world governments have implemented stringent emission norms to reduce the pollution created by hydrocarbon combustion in automobiles. The use of gaseous fuels in IC engines has gained interest among the research community. In the present research work, hydrogen, and oxygen (HHO gas) are produced together in an electrolyzer unit and is fed into the engine intake manifold before the carburetor. The electrolyzer consists of an anode, cathode and five neutral plates made of 316 L SS. Electrolyser production rate was tested with four different molarity conditions of NaOH electrolyte solution ranging from 0.24 to 1 N. It was noted that a maximum of 2 LPM of HHO gas was produced with the supply of 90 A‐h current at 1 N solution concentration. The performance and emission characters of the SI engine were conducted at six different load conditions and four flow rates of HHO gas. HHO gas induction has significantly increased the thermal brake efficiency by 8% and decreased the specific fuel consumption by 20%. With the supply of 2 LPM of HHO gas, CO2, HC, and NOx emissions were reduced by 67%, 59%, and 34%, respectively.

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.

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.
