“…This can contribute to lower CO emissions. Adversely affects engine POLYUNSATURATED OIL -When high linoleic/linolenic acid oil is used, the engines often cannot last long enough to perform long duration testing [12]. The cylinder buildup and ring corrosion is so severe that catastrophic engine failure occurs [10].…”

SAE ABSTRACTThe combustion of straight vegetable oil (SVO) in internal combustion engines has shown conflicting results in emissions, power, and engine longevity. Many early studies suggested that SVO should not be considered for long term use in diesel engines. However, waste vegetable oil has been fueling adapted vehicles in progressive communities for years. The issues involved in the combustion of SVO or pure plant oils are complex. Engine injection systems, oil type, lipid acid ratio, and fuel temperature all have significant impact on the engine performance and emissions. A review of published studies of SVO combustion with a focus on known SVO composition and chemical structure reveals trends which merit further study. Future engine tests with known vegetable oil profiles will add significantly to the progression of SVO use in engines.

“…The irst approach consisted on directly using vegetable oils without any chemical transformation as direct fuel. Thus, soybean oil [35], sunlower oil [36], canola oil [37] or rapeseed oil [38] have been studied. However, the direct use of vegetable oils or the use of blends with traditional petroleum-based diesel has not been considered a suitable solution due to the high viscosity, the gum formation due to oxidation processes and the deposition of carbon on piston and head of the engines [39].…”

Grape processing produces a substantial amount of residues that are highly polluting and expensive to treat, being grape seed one of the main by-products with high commercial interest. During the extraction process of grape seed oil, most of the nutraceutical compounds remain on the solid cake. This book chapter resumes the potential utilization of grape seed oil for producing biobased materials through environmentally friendly processes that could substitute petroleum-derived products. Special atention is given to transesteriication and epoxidation processes. The transesteriication of grape seed oil in presence of methanol drives to the production of a biodiesel with excellent low-temperature properties. According to EN 14214, grape seed oil-based biodiesel presents a slightly lower cetane number than the speciied limit. In addition, this biodiesel presents a low oxidation stability which can be improved by the incorporation of oxidation stabilizer. Atending to the epoxidation of grape seed oil, short reaction times and high temperatures are advised. Epoxidized grape seed oil can be used for the synthesis of biobased polyols and its further application on the synthesis of polyurethane compounds.

Biodiesel has become more attractive recently because of its environmental bene®ts and the fact that it is made from renewable resources. The cost of biodiesel, however, is the main hurdle to commercialization of the product. The used cooking oils are used as raw material, adaption of continuous transesteri®cation process and recovery of high quality glycerol from biodiesel by-product (glycerol) are primary options to be considered to lower the cost of biodiesel. There are four primary ways to make biodiesel, direct use and blending, microemulsions, thermal cracking (pyrolysis) and transesteri®cation. The most commonly used method is transesteri®cation of vegetable oils and animal fats. The transesteri®cation reaction is aected by molar ratio of glycerides to alcohol, catalysts, reaction temperature, reaction time and free fatty acids and water content of oils or fats. The mechanism and kinetics of the transesteri®cation show how the reaction occurs and progresses. The processes of transesteri®cation and its downstream operations are also addressed. Ó
