“…Biodiesels intrinsically containing a greater amount of double bond molecules caused a higher adiabatic flame temperature which in turn leads to a greater concentration of NOx emissions. In the case of nanoparticle blends, an increase in combustion temperature caused due to a greater rate of reaction and conversion of the oxygen present in the nanoparticle blend led to an increased rate of NOx emissions [33]. Under most engine loads, the NOx emissions of J100 were higher than those of J100A1000 fuel.…”

“…Up to 12% improvement in BTE, 30% reduction in NO emission, 60% reduction in CO emission, 44% reduction in UHC emission and 38% reduction in smoke emission were observed when both cerium oxide and alumina nanoadditives was added to B20 jatropha biodiesel blend as compared to B100 fuel [33]. Ignition delay was affected when nanoadditives were used in the fuel.…”

Summary Biodiesel obtained from inedible sources emerged as a productive approach in Indian energy scenario due to the scarcity of food resources come up with extensive usage of edible crops. Kusum (Schleichera oleosa) oil is abundantly available in India and can be used as feedstock to produce biodiesel. However, issues such as higher viscosity, poor stability, and lower calorific value result in poor ignition characteristics, hence limiting its use in combustion applications. An improvement in performance and emission characteristics can be achieved by doping nanoparticles in Kusum biodiesel (KBD). The present work examines the impact of a metal compound and carbon‐primarily based nanoparticles on the evaporation time and ignition probability of the KBD. During the experimental process, different fuel samples of KBD were prepared by amalgamating nanoparticles; then, a sequence of hot plate (stainless steel) ignition test was conducted on these test fuels. The comparative assessment of neat biodiesel and the biodiesel fuel doped with 30 ppm each of alumina (Al2O3), and multiwalled carbon nanotubes (MWCNTs) nanoparticles were carried out. The Kusum oil was converted to biodiesel using two‐stage transesterification process. In the initial stage, refined oil was gone through the acid catalyst esterification process followed by the transesterification reaction. The prepared methyl ester was confirmed and characterized using GC‐MS technique. The thermophysical and spray properties of the test fuels including density, viscosity, calorific value, cloud/pour point, Sauter mean diameter (SMD), and specific surface area (SSA) were also calculated. The experimental result showed a significant increase in ignition probability and heat conduction properties due to improved surface area/volume ratio. Also, lower evaporation time was noted for metal/carbon‐based nanoparticles doped biodiesel as compared with neat biodiesel.

“…Another approach to the improvement of the environmental characteristics of the rolling stock diesel engines is to improve fuel quality by adding mixtures containing nanoparticles. In this particular case, it is possible to distinguish fuel mixtures for biodiesels with the addition of molybdenum trioxide [4], alumina hydroxide [5], composite 30 ppm nanoparticles Alumina (Al2O3) and Cerium oxide (CeO2) [6]. The addition of graphene oxide GO nanoparticles to the fuel [7] is very encouraging for improving the environmental cleanliness of diesel engines that shows a reduction in emissions of NOx by 45%, CO by 55%, and CH by 50% for a conventional diesel engine.…”

A method for measuring diesel engines characteristics based on recording the irregularities of time parameters of the crankshaft rotation is proposed. We demonstrate that the change of diesel engines characteristics significantly affects the established norms and limit values of engine emissions of pollutants and harmful substances. The ways of improving the environmental characteristics of diesel engines, including change of fuel composition by adding mixtures are considered. A method of control of the diesel engine parameters consisting in measuring the instantaneous values of the speed of the crankshaft rotation and assessing the deviations of these parameters from normal values has been proposed. The method is implemented in the form of procedures including data collection from sensors installed on the engine, data filtering, and their characteristic analysis. An autonomous measuring device based on the microcontroller has been developed with the help of which data has been collected from the sensors of the 16-cylinder turbocharged engine. We have carried out experiments on process data that determine possibly faulty engine elements that worsen its environmental parameters.
