the gradual depletion of fossil fuels and the increase on their cost have made the researchers to look for renewable sources of energy. biodiesel fuel has attracted many researchers due to its low environmental pollution and being a renewable fuel. in this research, biodiesel was prepared by transesrtification of persian lilac seed oil. the prepared fuel was mixed with regular petro diesel in 0...

The finitude and environmental impact of petroleum fuels have led to the search alternative biodiesel has proven be an fuel petro-diesel with less impact. Engine performance exhaust emissions Sandbox Methyl Ester (SBME) were evaluated. Pure SBME (B100) was blended diesel at 5, 10, 15, 20, 25 50% volume designated B5, B10, B15, B20, B25 B50 respectively. used as a reference fuel. blends (B100-B5...

Recently, studies have been carried out using environmentally sustainable technologies with more efficient energy conversion to fulfill emission requirements. One of these technologies, reactivity controlled compression ignition (RCCI), is a low-temperature combustion mode and has dual fuel strategy. The controllability combustion, high thermal efficiency low nitrogen oxide (NOx) soot emissions...

In the present study, effects of water addition into intake air (WAIA) on engine performance and exhaust emissions have been investigated experimentally in an automotive spark-ignition (SIE) which is used Renault Clio vehicles. Experiments performed for (3, 6, 9 12) % (by vol.) ratios (WRs) at different speeds loads. Selected were (3000, 4000 5000, 6000) rpms. 6000 rpm maximum speed this engine...

In this study, experimental tests were carried out to improve the performance and emission characteristics of diesel engine as amyl alcohol (pentanol), which is in heavy class, obtained from residual waste etha-nol, produced a by-product during sugar production beet. Tests performed on naturally aspirated, air-cooled, four-stroke, single cyl-inder, direct injection, 6LD 400 Antor at full load s...

As a hard-to-decarbonize sector, the shipping industry is experiencing demands to accelerate transition from fossil fuels alternative low-carbon fuels, significantly reduce negative impacts on environment. Biofuels are regarded as one of solutions for decarbonization in marine sector. This paper introduces lignin-derived drop-in biofuel, 2-methoxy-4-propylphenol (2M4PP), non-edible feedstocks a...

Considering the trade-off relationship between brake specific fuel consumption (BSFC), combustion noise (CN) and NOx emission, it is a difficult task to optimize them simultaneously in marine diesel engine. In order overcome this problem, novel genetic algorithm improved chicken swarm optimization (GA-ICSO) hybrid was proposed, where enhanced Levy flight adaptive self-learning factor were intro...
