“…Biodiesel can also cause dilution of engine lubricant oil, requiring more frequent oil changes than when using petroleum diesel fuels in conventional diesel engines. This increase in dilution and polymerisation of engine sump oil is due to the higher viscosity at lower temperatures of biodiesel compared to petroleum diesel [9].…”

“…Moreover, the different chemical structure of biodiesels influences the formation of NO x emissions and most of the authors agreed that shorter chain lengths and more saturated biodiesels were preferable to reduce NO x emission. Knothe et al [9] tested NO x in a six-cylinder diesel engine with conventional diesel fuel and three different fatty acid methyl esters including oleic (C18:1), palmitic (C16:0) and lauric (C12:0). They found a 4% and 5% reduction in NO x emissions for the saturated palmitic and lauric esters, respectively, and a 6% increase for the oleic ester.…”

“…When using biodiesel as a fuel, unoptimized engines may show increased problems with carbon deposition, corrosion, lubricating oil contamination, poor low temperature performance, and heavy gum and wax formation compared to petroleum diesel [9]. The differences in performance between petroleum diesel and biodiesel may be attributed to the variation between their physical properties and their chemical compositions.…”

Abstract:Over the past few decades, biodiesel produced from oilseed crops and animal fat is receiving much attention as a renewable and sustainable alternative for automobile engine fuels, and particularly petroleum diesel. However, current biodiesel production is heavily dependent on edible oil feedstocks which are unlikely to be sustainable in the longer term due to the rising food prices and the concerns about automobile engine durability. Therefore, there is an urgent need for researchers to identify and develop sustainable biodiesel feedstocks which overcome the disadvantages of current ones. On the other hand, artificial neural network (ANN) modeling has been successfully used in recent years to gain new knowledge in various disciplines. The main goal of this article is to review recent literatures and assess the state of the art on the use of ANN as a modeling tool for future generation biodiesel feedstocks. Biodiesel feedstocks, production processes, chemical compositions, standards, physio-chemical properties and in-use performance are discussed. Limitations of current biodiesel feedstocks over future generation biodiesel feedstock have been identified. The application of ANN in modeling key biodiesel quality parameters and combustion performance in automobile engines is also discussed. This review has determined that ANN modeling has a high potential to contribute to the development of renewable energy systems by accelerating biodiesel research.

The aim of this research was to study the pyrolysis oil production from Palm Oil Grade III (POG-III) and popular wood sawdust crude oil. Today, worldwide studies have been undertaken on the biomass usage and co-conversion of biomass and coal to seek out alternative fuels for supplying energy in an environmental friendly way. Substitute fuels have become more and more vital due to descending petroleum reserves, increasing economic circumstances and awareness of the increased environmental penalties of emissions from petroleumfuelled engines. In this study, biodiesel fuel was manufactured by the nanocatalytic to elucidate their thermal behaviour under pyrolysis conditions and to assess major decomposition products in terms of their yields. Transesterification of Palm Oil Grade III (POG-III) at 80°C temperature by using nano Co as nanocatalyst. The prepared biodiesel was characterized by FT-IR and GC-MS. Results revealed the presence of esters, alkanes, alkenes, saturated and unsaturated hydrocarbons with carbon chain in the range C 9 -C 27 . Prepared biodiesel is cost effective and highly efficient. Besides Palm oil popular wood sawdust crude oil was also used. All products were obtained at low temperature and at low atmospheric pressure.

“…Biodiesel can be formulated from a diverse range of animal fats, vegetable oils or greases by dilution, pyrolysis, trans-esterification and micro-emulsion process. The biodiesel has very similar properties to the diesel fuel [3]- [6]. In the last few decades, the production of biodiesel and its performance in diesel engines have been investigated.…”

Abstract-Automotive and transportation sectors will be inclined towards the renewable or green energy in the near future. One of the green energy sources discovered recently is biodiesel. Biodiesel is a source of clean alternative fuel for internal combustion engines, which reduces the exhaust emissions significantly. Like diesel, biodiesel also emits exhaust particulate matter (PM), which is responsible for the black soot coming out from the diesel engine. However, it is not clear that what will be the size of PM formed during the idle speed of a biodiesel fueled engine. In this study, the characteristics of the exhaust particulate during the idling speed of a biodiesel fueled single cylinder diesel engine is analyzed. Biodiesel showed a positive result in terms of the concentration of emitted PM. However, particle sizes were smaller in case of biodiesel than diesel. Further studies should be carried out to improve the properties of biodiesel to ensure that the emitted particle sizes are not toxic to human health.Index Terms-Biodiesel, idling, internal combustion engine, particulate matter emission.
