Different mixtures of diesel-vegetable oils as fuel

摘要

Biofuels are the fuels that are being produced from biomass. Furthermore, biofuel is defined as solid, liquid or gas fuel derived from relatively recently dead biological material. They can replace conventional fuels, completely or partially, in the internal combustion engines. Some of the consequences of crude oil dependence are the increasing price of crude oil, the important changes in oil market, the finite of reserves as well as the environmental pollution. Therefore, there is a big need to produce appropriate fuels, which will have minimal environmental and social degradation. This led to the revaluation of the importance of the rural and forestall factor as a renewable resources supplier. This work examines the behavior of a four-stroke Diesel engine when mixtures of diesel-vegetables oils (sunflower oil, olive seed oil, cotton oil) are used as fuel. For those mixtures the gas emissions of carbon monoxide (CO), hydrocarbons (HC), nitrogen monoxide (NO) and smoke emissions are being examined.
