THE USE OF BIOFUELS ON COMPRESSION-IGNITION ENGINES AND THEIR IMPACT ON THE FILTER ELEMENT
Abstract
Despite its recognized negative impact on nature and human health, the worldwide nations are still strongly depended on fossil fuel for their transport needs. In the present geopolitical turmoil, all EU Member States ought to look for alternative fuels that would ensure a minimum self-sufficiency for their essential supply lines. The biofuels can offer an important alternative towards reduction of fossil fuels for short and medium term. The present study observed that by using biofuels to power the MAC engines that equip tractors and cars, significant advantages are obtained compared to the use of diesel. An extra 10% oxygen, obtained based on the changes made to the fuel system, yields a considerable reduction of chemical pollution. The best performance in terms of pollution, power, momentum and consumption were obtained with the following mixtures: 30% and 40% biodiesel with diesel, respectively 20% biodiesel + 5% methanol + diesel. The only shortages in the current process are due to the multifarious composition of crude biodiesel, involving complex, energy-intensive separation stages, which is reflected in the final costs of the products.
