“…The results showed that the use of WCO resulted in higher brake specific fuel consumption with regard to the exhaust emissions; the use of WCO generally resulted in a lower CO 2 and HC; under most of the operating conditions, NO x produced by biodiesel (100% v/v) was lower compared to that of diesel fuel. Can [25] experimentally investigated the combustion development of a single-cylinder diesel engine fuelled with WCO blended in 5 and 10% with diesel fuel. An increase in NO x emissions and a decrease in smoke and HC was found.…”

The employment of biofuels in blends with diesel oil proved to attain a reduced environmental impact without compromising the engine performance. Among biofuels, waste cooking oil offers the advantages of its reduced raw material cost in comparison with fresh vegetable oil cost; it also eliminates the environmental impacts caused by its disposal. Although a great number of researches has been devoted to biodiesel combustion in engines and pollutant emissions, few studies can be found on light duty diesel engine equipped with up-to-date technologies. This work aims at investigating the impact of waste cooking oil percentage in blends with diesel oil on the performance and emission characteristics of an up-to-date light and compact common rail diesel engine whose main application is in microcars and in urban vehicles. A comprehensive experimental activity was performed in the engine complete operative field. The comparison of the results with those obtained with standard ultralow-sulfur diesel highlighted that the engine performance was quite similar for B20 and diesel oil. B40 suffered for the lower caloric value in regard to diesel. A reduction in CO and HC was obtained with biodiesel blends, along with an increase in NO x . Particulate emissions were also reduced for biodiesel blends; the mean size of particles was smaller as regards diesel oil.

“…Biodiesel is the mono alkyl esters of fatty acid derived from vegetable oil through transesterification with methanol or ethanol using catalyst [3], which is directly used as fuel in ignition compression engine or as blend with petroleum diesel to enhance its Cetane number, lubrication and exhaust emission properties [4]. It is considered as an alternative green source of energy [5], due to its renewability, does not contain sulphur and aromatic compounds hence it is environmentally friendly [6,7], since the CO 2 produced during its combustion will be absorbed by another plant during photosynthesis thereby reducing global CO 2 level [8]. Therefore biodiesel is the best substitute to convectional diesel due to their similar properties [9].…”

Abstract:Increase in environmental pollution due fossil fuel exhaust emissions coupled with petroleum fuel depletion leads to search for the alternative green sources of energy. In views of this, methanolysis of gingerbread plum (Parinari macrophylla) seed oil had been carried out using 5wt.% MgO/Al 2 O 3 catalyst to produce biodiesel and assess its fuel quality as a source of green energy. The results produced a biodiesel with 97% yields, 0.60g/cm 3 density, 0.42% water and sediment content, 0.45mg/KOH acid value, 84.20mg/KOH saponification value, 75mg I 2 /100g Iodine value, 94.24 Cetane index and high heating value of 49MJ/Kg. The GC/MS results indicated the presence of methyl-9-octadecenoate, methyl-12-octadecenoate, methylhexadecanoate esters, octadecanoic and oleic acids. The methyl ester biodiesel produced therefore, promises to be a viable source of green energy for future use.

“…In general, a decrease of particulate emission, hydrocarbons, and carbon monoxide is observed with increasing of biodiesel content in the blends; biodiesel leads to increased nitrogen oxides (NO ) compared to petroleum diesel [4,5]. Among all suitable biodiesel fuels, waste cooking oil (WCO) is considered a promising option and has demonstrated its suitability to be used as biofuel in diesel engines [6,7]. It offers advantages when used as a fuel source: WCO is 2-3 times less expensive than virgin vegetable oils [8]; the conversion of WCO into fuel also eliminates the environmental drawback caused by its disposal.…”

The purpose of this paper is to conduct an experimental research on the impact of mixing ratio of biodiesel from waste cooking oil and an innovative diesel fuel (in which a renewable component is contained) on the emissions of an up-to-date light and compact small engine that has a leading role in city cars and urban vehicles. Two blends' mixing ratios (20% and 40% by volume) were tested and the results were compared to those obtained when the engine was operated with low sulfur diesel (ULSD) and ULSD blended with 15% by volume of renewable diesel. The results indicate that diesel+ enhances CO and HC emissions in the exhaust as regards ULSD. Blending diesel+ with WCO causes a further reduction for most of the engine operative field. Concerning particulate emission, accumulation mode dominates for all fuels. Diesel+ is always characterized by lower mean diameters as regards ULSD. The addition of WCO further reduces the court mean diameter. Particle number concentration obtained by fuelling the engine with B40 is the lowest as regards all the other tested fuels. Concerning NO , a moderate increase of the emission was observed when fuelling the engine with diesel+, net or in blends.
