Nanoparticles are an emerging concept for increasing fuel properties. The purpose of this research work is to determine the effect of magnesium oxide nanoparticles on the performance and emission characteristics of diesel engines that run on a spirulina microalgae biodiesel blend (B20) as a fuel. The ultrasonication was used to disperse MgO nanoparticles in B20 fuel at various concentrations (25, 50, 75, and 100 ppm). The significant findings indicated that B20+100 blends reduced specific fuel consumption by 20.1% and had a 5.09% higher brake thermal efficiency than B20. B20+100 blends reduced CO, hydrocarbon, and smoke emissions by a maximum of 32.02%, 30.03%, and 26.07%, respectively, compared to B20.

The paper presents an experimental investigation, to evaluate the performance and emission characteristics of a direct injection diesel engine using diesel-ethanol blends with aqueous cerium oxide nano fluid (ACN) as additive at different load conditions. The test fuel (D85E15ACN) prepared using ultrasonic sonicator, contains diesel 85%, ethanol 15% (D85+E15) by volume, with 1ml of aqueous cerium oxide nanofluid (ACN) added with the blend. The results show that, when the engine is run with D85E15ACN, there is an increase in brake thermal efficiency and reduction in hydrocarbon (HC), carbon monoxide (CO) and smoke emissions, compared to that of neat diesel.However, nitric oxide (NO) emission are more for D85E15ACN.

This research work investigated the diesel engine performance using 20% Pongamia grease methyl ester through the effect of different flow rates of acetylene using dual-fuel technique. Acetylene be inducted within the intake various at the flow rates of 1lpm, 2lpm, 3lpm and 4lpm along with air. Initially a test was conducted by diesel fuel along with POME20 on different loads. Then the experiment was carried out with POME20 with different flow rates of acetylene. Addition of acetylene increased the brake thermal efficiency (BTE) among POME20 at all acetylene flow rates on 100% load. The results showed that the BTE was enhanced via regarding 1–3.4% at knock-limited acetylene shares at 100% load. The engine emits higher NOx emission for POME20 without acetylene share and then it is additional improved with the adding up of acetylene shares, while the smoke opacity was reduced by 47% with acetylene addition at complete load. Here is a decrease in HC as well as CO emissions were experiential through an acetylene orientation along with POME20. Finally, it is suggested that the poor presentation as well as emissions connected through biodiesel into a diesel engine can be improved through the induction of acetylene with 4lpm flow rate in the intake various by dual fuel technology.
