“…It is attributed to the lower kinetic viscosity of pine oil compared to diesel, which increased the spray penetration distance and spray breakup length of P40. 34 Besides, the in-cylinder pressure was low during the pre-injection process. An increase in the PIR prompted more fuel impingement on the cylinder wall, which caused the local mixture to be over rich and increased the soot emission.…”

“…This result is consistent with the results of many studies, some of which are mentioned in Table 1 . 36 , 38 , 41 , 45 , 56 , 63 Teoh et al 56 showed that variation in HC emissions is not related to engine speed or load but to the combustion chamber and fuel injection system designs. Valente et al 83 reported an increase in hydrocarbon concentrations with increased engine load as a direct result of combustion efficiency.…”

The operation of engines using rapeseed methyl ester (RME) and ultralow sulfur diesel (ULSD) was tested for the combustion properties, emitted regulated, unregulated exhaust pollutants, and the size of nanoparticles. The combustion analysis showed higher apparent heat release rate and shorter ignition delay period during RME combustion than during ULSD combustion. The ULSD engine has a combustion chamber maximum pressure relatively higher than that of RME. This study showed that the heat release rate of ULSD is always higher than that of RME while more fuel consumption occurred from the combustion of biodiesel in comparison with diesel. When the engine is running on RME, HC and NOx formation increased at high loads up to 15% and 13%, respectively; meanwhile, CO concentrations reduced by 30.9% for the same conditions. Most of the particulate matter (PM) emitted from a diesel engine has a particle size from 5 to 100 nm, while the particle size from ULSD ranged from 5 to 40 nm. Overloading the engine caused a decrease in the sizes of emitted PM for both fuels. The smoke number for RME was less than that for ULSD by 33.9% at high loads. For high engine load, the cumulative concentration number for the nucleation mode decreased, while it increased for the accumulation mode. Furthermore, measurements of formaldehyde, ethane, methane, acetylene, ethylene, propylene, and isocyanic acid emissions showed the presence of these harmful substances at very low concentrations (8 ppm) for both fuels.

“…The oil is pale yellow and has a fresh forest smell and odor; it is easily soluble with alcohol and other mineral oils. The oil is extracted from the oleoresin by a steam-distillation method before it is treated with some acids to synthesize the required pine oil. , The oil in appearance has much lower viscosity, and this property is closely comparable with that of eucalyptus. The chemical structure of pine oil consists of hydrocarbon molecules with oxygen, and it is called an alicyclic hydrocarbon.…”

Under the roof of solid industrialization and accelerated intensification of multiple ranges of mobilization, a huge rise in precious fuel consumption and pollution was observed. Based on the recent hardships of fossil fuels, experts are undoubtedly eager in carrying out their research in renewable environment-friendly fuels. There have been many reviews of works considering the parameters and standards of biodiesel, which is only from various vegetable and seed oils. But very little review work was carried out on only plant-based biofuel. Plant-based fuel has a lower viscosity and higher volatility properties. The target of this review was to make a bridge to overcome these research gaps. This review extensively studies the biological background, production outcome, properties, and reliability of plant-based biofuel and also deeply investigates the feasibility of usage in a diesel engine. From deep investigation it was identified that most of the low viscous fuel had higher brake thermal efficiency (BTE) (2% to 4%) and NOx emission (5% to 10%) than high viscous biodiesel. The formation of hydrocarbon (HC), CO, and smoke emission was similar to high viscous biodiesel. Overall, the low viscous fuel effectively improves the engine behaviors.
