“…All tests were run on a 406 cc, single-cylinder, air-cooled, 4-stroke, direct injection diesel engine (ultra-lean mixtures with very high airfuel ratios can only be achieved by direct injection engines). 33 The maximum output power of the engine was 6.3 kW at 3000 rpm. A blend of 80% diesel fuel and 20% palm oil biodiesel (B20 POBD) as popular biodiesel and blend ratio was prepared and used the effect of fuel temperature on SFC and CO increases as the output power decreases.…”

The impact of inlet fuel temperature on the performance and emission characteristics of a 406 cc, single‐cylinder, air‐cooled, 4‐stroke, direct injection (DI) diesel engine was investigated to determine the suitable temperature of fuel for the best conditions of the engine in lean and ultra‐lean mixture combustion mode. B20 palm oil biodiesel‐diesel blend fuel (B20 POBD), as common renewable fuel and favorite biodiesel blend ratio used in the research, was provided and injected in the engine at varying temperatures in the range of 10–40°C and the engine parameters including the output power, specific fuel consumption (SFC), thermal efficiency, flue gas heat recovery efficiency and CO and NOx pollutant emissions were measured at different air–fuel ratios corresponded to lean and ultra‐lean mixtures. The results showed that there is an optimum temperature for fuel (about 20°C) in which maximum thermal efficiency and minimum SFC and CO emission are obtained. The minimum SFC and CO emission were 0.45 Kg/kWh and 610 ppm at the optimum temperature and output power of 1.5 kW, respectively. The effect of fuel temperature on SFC and CO increases as the output power decreases and for all fuel temperatures, the output power is inversely related to the air–fuel ratio. In addition, the elevated output power reduces the CO emission in all inlet fuel temperatures. Furthermore, an ultra‐lean mixture (very high A/F ratio) can dramatically decrease the thermal efficiency of diesel engines at all fuel temperatures, such that at the inlet fuel temperature of 17°C, increase in A/F ratio from 51 to 108 decreases the thermal efficiency from 16.8% to 0.12%. Finally, low engine output power leads to low levels of NOx emission, such that decrease in output power from 1.5 to 0.5 kW reduces the NOx emission from 522 to 204 ppm, respectively.

“…Pourhoseini et al [46] took a single-bar, air-cooled, four-stroke direct injection diesel engine as the research object and optimized the cold flow performance of biodiesel by adding iron nanoparticles to B20. The experiment showed that when the engine starts at 0 • C, adding iron nanoparticles to biodiesel could reduce the viscosity of the mixed fuel by 14%.…”

Reducing diesel engine emissions under cold start conditions has become much more valuable as environmental issues become more important. Regarding diesel engine emissions under cold start conditions, this review summarizes the emission mechanisms and specifically focuses on the research progress of four reduction strategies: biodiesel utilization, intake heating, injection optimization, and aftertreatment technologies. In general, adding biodiesel and Di-Ethyl-Ether (DEE) could provide the benefit of reducing emissions and maintaining engine performance. Intake heating and appropriate injection strategies could also effectively reduce emissions under cold start conditions. Unlike normal operating conditions, lean nitrogen oxide traps (LNT) or electrically heated catalysts (EHC) should be utilized in the aftertreatment of diesel engines to minimize emissions under cold start conditions. By offering the valuable information above, this review could be a helpful reference in reduction strategies for diesel engines under cold start conditions in both academia and industry.

This study investigates the effects of magnesium oxide (MgO) nanoparticles on combustion performance and emissions in diesel engines. MgO's well‐ordered crystal structure, high thermal stability, and oxygen‐carrying capacity positively influence engine performance. The effects of 50 and 100 mg/L MgO concentrations were compared, showing up to a 5% improvement in brake thermal efficiency at 100 mg/L. Additionally, reductions of 8% in CO and 10% in HC emissions were achieved. MgO's crystal structure contributed to higher combustion temperatures, leading to lower harmful emissions. However, an increase in NOx emissions was observed, indicating the need for careful balancing between performance improvements and emission control. These results highlight MgO as an efficient and environmentally friendly fuel additive.
