“…The number of studies on biofuels as new energy sources has increased due to the problems such as the decrease in petroleum-based fuels, uncertainties in the energy demand in the future and the increasing threat of global warming [1,2]. The most widely investigated biofuels for internal combustion engines can be sorted as biodiesel, bio-alcohols, biogas and hydrogen.…”

In this study, bioethanol produced from sugar beet and biodiesel produced from waste cooking oils was blended with each other in the volumetric rates to be 20% and 80%, respectively. Cetane improver (di-tert-butyl peroxide) was added into blend fuel in 1-2-3% as volumetric. The obtained blends were used as a fuel in the diesel engine which is single-cylinder, directinject, four-stroke. The tests were conducted under four different engine loads (25%, 50%, 75% and 100%) and 1400 rpm engine speed. The test results showed that brake-specific fuel consumption was decreased up to 15.5% thanks to the addition of cetane improver, although biodiesel and bioethanol increased brake-specific fuel consumption by 16.1% and 27.54%, respectively. However, brake thermal efficiency values were increased up to 9.44% with both biodiesel and cetane improver added blend fuels, while brake thermal efficiency was decreased by 3.88% with bioethanol addition. The more compatible combustion characteristics with that of diesel fuel have been obtained due to especially the increase in cetane number. The use of biofuels increased both maximum cylinder pressure and heat release rate. While, with the cetane improver addition, a decrease in CO, HC and smoke opacity values was observed up to 22.5%, 17.44% and 24.44%, respectively, CO 2 , NO X and exhaust gas temperature values were increased up to 19.55%, 5% and 15.22%, respectively, according to bioethanol blend fuel.

Akin to biodiesel, hybrid fuels are gaining attention as a substitute to petro‐diesel, because of low processing cost of fuel production, having comparable engine performance, and significantly lower amount of emissions. This study presents experimental investigations on production of biodiesel and hybrid fuels from waste cooking oil and analyzes its behavior in an existing CI engine without the alteration of fuel injection settings. The biodiesel was produced by transesterification process and hybrid fuels were prepared by 3‐phase titration method. The physico‐chemical properties of fuels were evaluated as per ASTM/EN standards and compared with petro‐diesel. Biodiesel, blends of biodiesel and hybrid fuels were then analyzed for engine performance, emission, and combustion characteristics at constant speed and variable loading conditions. Biodiesel blend B30 showed higher brake thermal efficiency, lower brake specific energy consumption, and lower exhaust emissions (except NOx level), whereas, hybrid fuels showed a significant reduction in NOx level and comparable other exhaust emissions (except unburnt hydrocarbon) at the cost of lower brake thermal efficiency when compared with diesel. © 2019 American Institute of Chemical Engineers Environ Prog, 38:e13112, 2019

“…He found that the highest in-cylinder pressure was measured with M30 at 15 Nm engine load. Uyaroğlu et al [31] mentioned that no big differences were seen on cylinder pressure between hazelnut oil-diesel (H30), corn oildiesel (C30), soybean oil-diesel (S30), sunflower oil-diesel (Su30), canola oil-diesel (Ca30) and Crambe abyssinica oil-diesel (Cr30) and diesel fuel blends. They have also stated that eralier combustion occured with biodiesel-diesel fuel blends.…”

In this study, the biodiesel obtained from the waste olive oil by transesterification method has been mixed with a 30% of diesel fuel as volume and tested with a single cylinder direct injection diesel engine. The main purpose of this study is to obtain purer biodiesel from waste olive oil using methyl alcohol (CH3OH) and sodium hydroxide (NaOH) as catalyst in the transesterification method and research performance, combustion and emission characteristics in detail in a direct injection diesel engine. The combustion, engine performance and exhaust emission values have been also compared with diesel fuel. The test engine was operated at a constant speed of 2200 rpm and different engine loads such as 3.25 Nm, 7.5 Nm, 11.25 Nm, 18.75 Nm. According to the experimental results, the thermal efficiency of biodiesel is lower by about 1% to 5% than diesel. CO is lower about 37.5 % with biodiesel than that of diesel at 18.75 Nm. CO2 is higher 41% with biodiesel than diesel at 11.25 Nm. NOx was measured 9.5% higher than diesel fuel at 18.75 Nm. Soot emissions decreased by 37.5% compared to diesel.
