“…49 Another study illustrates that a novel air conditioning system powered by solar energy can enhance vehicle fuel efficiency, demonstrating a 25% reduction in fuel consumption compared to conventional systems, along with improved cooling and heating capabilities; additionally, the solar-powered system leads to decreased harmful engine emissions. 50 Several research areas have emerged from current study which are worth further exploration in future work. Firstly, our life cycle optimisation model can be further congured to consider open-loop or closed-loop waste (in liquid, gas, solid phases) recovery to inform circular-economy decisions.…”

“…The main reason to justify this trend may be because of the reduction oxygen concentration inside the cylinder from the applied EGR Varatharajan and Cheralathan, 2013). Another cause is the reduction in the flame temperatures during combustion (Dhahad et al, 2019;Alani et al, 2022). Furthermore, Figure 4 shows that the NOX emissions are higher in case of E10 when compared with diesel fuel.…”

Recently, most of the researchers focused on provide lower greenhouse gas emissions that emitted from diesel engines by using renewable fuels to be good alternative to the conventional diesel fuel. Ethanol can be derived from renewable sources such as sugar cane, corn, timber and dates. In the current study, the ethanol fuel used in the tests was derived from the dates. The effects of using exhaust gas recirculation (EGR) diesel-ethanol blend (E10) with on engine performance and emissions characteristics have been studied in diesel engine under various engine loads. This study focused the use of oxygen in the bio-ethanol composition to compensate for the decrease occurred by the addition of EGR, which improves the engine performance and reduces its emissions. In this experiment, the ratios of EGR were 10%, 20% and 30% as well as 10% ratio of ethanol was blended into the diesel fuel blend under fixed engine speed. A traditional (without additional systems to reduce emissions) four cylinders direct injection (DI) diesel engine was used for all tests. The brake specific fuel consumption (BSFC) increased with increasing the EGR ratio by 10%, 20% and 30% by 18.7%, 22.4% and 37.4%, respectively. The thermal efficiency decreased under variable conditions of engine load for different ethanol blends. Furthermore, the emissions of NOX decreased when fuelled B10 into the engine in comparison with diesel under low engine load. Significant reduction in the NOx emissions were found when applied EGR in the tests than to the absence EGR for E10 blend and diesel. The NOx reduction rate was 12.3%, 30.6% and 43.4% when EGR rate was 10%, 20% and 30%, respectively. In addition, the concentrations of HC and CO emissions decreased more by 8.23% and 6.4%, respectively, when using E10 in comparison with the diesel for various engine loads. It is indicated that the oxygen reduction by EGR effect was compensated from ethanol blend combustion. The results showed that the combination use of E10 and EGR leads to significant reduction in engine emissions accompanied with partial reduction in the engine performance.

“…The growing using fossil fuel in various transference sectors, produces important attention in the global as a result of the environs contamination and worldwide warming [1]. The sun is regarded as a main resource of energy for its cleanliness and constancy, different other types of energy for example oil, coal, and derivations of oil that contaminate the environs and air.…”

Renewable energy sources are becoming more and more popular, regarding the pollution and non-sustainability of common energy sources. Photovoltaic is the most direct way to convert solar radiation into electricity using the photovoltaic effect. This technology generates direct current (DC) electrical power from semiconductors when they are illuminated by photons. This paper presents a mathematical model in CFD that simulates the thermal presentation of a solar thermal photovoltaic panel equipped with circler, square and elliptic pin fin cooling module. The effect of cooling water velocity on photovoltaic panel average temperature and average cooling water temperature has been studied and the effect of cooling water velocity on photovoltaic panel average temperature and average cooling water temperature. The results show that velocity contours for water flows in circular, elliptic and square pin fin cooling module with inlet water velocities (0.0002, 0.0004 and 0.001 m/s). It is noticed that for square pin fin, the velocity between the pins is higher than the other types of pins, which leads to more circulation of water and more cooling.
