  • Internal combustion engines are playing a major role in the road transportation due to the potential for the increase of efficiency and the reduction of the pollutant emissions, the available infrastructure for the fuel, the reliability, the production costs, and the customer acceptance. On the other side, the growing transport sector is considered to be one of the main reasons for failing to meet the Kyoto targets. In combination with the emission limits and new emission standards, the already very low CO2 emission levels have to be further reduced both for spark ignition and diesel engines. Particularly, in Europe the transport sector accounts for more than 30% of the total energy consumption in the Community. It is 98% dependent on fossil fuels with the crude oil feedstock being largely imported and thus extremely vulnerable to any market disturbance. Biofuel use has to increase from its present low usage - less than 2% of overall fuel - to a substantial fraction of the transportation fuel consumption in Europe (target of 25% in 2030). However, biofuels will mostly be used in compressed ignition and spark engines and/or if it is possible specialized engines will be used in certain applications or in dedicated fleets. The most commonly known biofuels are ethanol and biodiesel. Biodiesel is a renewable fuel that can be produced from a variety of vegetable oils including rapeseed oil, soybean oil, sunflower oil and palm oil. Waste fryer oil, which is considered toxic waste by the EPA (Environmental Protection Agency), can also be transesterified into biodiesel. Rapeseed Methyl Ester (RME) is the more widely used in Europe and Soybean Methyl Ester (SME) or imported palm oil in the USA they are collectively known as Fatty Acid Methyl Esters (FAME). The benefits of the biodiesel-FAME are well known: higher cetane number, low sulphur content, reduction of HC and CO emission, reduction of PM emission. Even if the materials compatibility, impact on low-temperature operability, increase in NOx emission, reduction of power and fuel economy, and higher cost of production must be evaluated [1, 2].
