“…In line with that, green energy carriers including biofuels or environmentally friendly processes/innovations such as waste heat recovery, exhaust treatment technology, and hybrid engines have been considered as strategies to address these challenges (Demirbas, 2017;Hoang, 2018b;Littlejohns et al, 2018). Biofuels could not only play an important part in satisfying the stringent emissions regulations but also could meet the energy and technical requirements of the existing engines (Cazarolli et al, 2016;Rajaeifar et al, 2017;Hoang and Pham, 2018a).…”

HIGHLIGHTSPreheated and unpreheated straight Jatropha oil, and fossil diesel fuel were experimentally compared. Spray characteristics, i.e., cone angle and penetration length were investigated. Thermal efficiency and emission parameters were tested at 0 h and after 300 h of engine operation. Trilateral correlation of spray characteristics, combustion parameters, and deposit accumulation in injector orifices was analyzed. Unpreheated straight Jatropha oil cannot be recommended for long term use in diesel engines.

“…The fruit is considered the most relevant part of the plant economically and presents as one of the main characteristics the high concentration of oil. The oil is used in pharmaceutical industry for the manufacture of cosmetics, in the food sector, as cooking oil and by the energy sector for the production of biofuels (Barreto et al, 2016;Cazarolli et al, 2016).…”

Classification of Macaw Palm Fruits From Colorimetric Properties for Determining the Harvest Moment

et al. 2018

Macaw palm (Acrocomia aculeata) is a promising crop for biofuel production due to the high concentration of its fruit oil, but the harvest date is an issue to be better understood so it could be cultivated on an industrial scale. The aim of this study was to use the colorimetric properties of the macaw palm fruits to develop a neural network classifier to determine the ideal moment for harvesting, based on the oil content of the fruit mesocarp. During nine weeks of maturation were sampled 900 fruits of macaw palm fruits and the colorimetric properties of the RGB, HSI and CIELab color models were used to classify the fruits into immature and mature fruits. Kappa index and the overall accuracy values were used to access the classifier performance. The classifiers based on RGB parameters and on hue were considered equivalents having a Kappa index of 0.901 and 0.942, respectively, indicating the 59 th week of maturation as the ideal time to harvest with the highest oil content.

The environmental sustainability of agricultural and industrial vehicles, as well as of the transportation sector, represents one of the most critical challenges to the sustainable development of a nation. In recent decades, compression-ignition engines have been widely used in on-road and off-road vehicles due to their better fuel economy, autonomy, compactness, and mechanical performance (spec. the high torque values). Due to the consistent environmental impact of fossil fuels, scientists are searching for alternative energy sources while preserving the beneficial features of diesel engines. The utilization of blends of diesel fuel, biodiesel, and bioethanol fuel (referred to as “ternary blends”) is among the most promising solutions for replacing fossil fuels in the near term, allowing, at the same time, us to continue using existing vehicles until new technologies are developed, consolidated and adapted to the agricultural and industrial sector. These ternary blends can lower exhaust emissions without creating major problems for existing fuel-feeding systems, typically designed for low-viscosity fossil fuels. One of the concerns in using liquid biofuels, specifically biodiesel, is the high chemical affinity with conventional and bio-based lubricants, so the main parameters of lubricants can vary significantly after a long operation of the engine. The comprehensive literature review presented in this article delves into the technical challenges, the main research pathways, and the potential solutions associated with the utilization of biofuels. Additionally, it investigates the emerging application of nanoparticles as additives in lubricants and biofuels, highlighting their valuable potential. This study also discusses the potential implementation of bio-ethanol in ternary blends, offering a promising avenue for reducing reliance on fossil fuels while maintaining engine efficiency.
