With the growing prices of fossil fuels and the concerns of global warming, the need to seek alternative fuels in the transportation sector is rapidly gaining momentum. This need of change has lead researchers to look beyond the typical alternative fuels for diesel engines and focus on Fatty Acids Methyl Esters (FAME), due to their high calorific value, widespread availability, and relative low cost. The authors investigated the injection and combustion of poultry fat FAME 20-50% by weight in diesel no. 2 mixtures. The dynamic viscosity of the FAME-diesel mixture has been investigated between 25-45°C and ranged from 3-5cSt increasing in correlation with the amount of FAME and lowered by the temperature increase. The new fuel containing up to 50% poultry fat FAME by weight in diesel fuel (B-50) has been injected by a piston-plunger type pump injection system. The injector had a 1x0.200 mm nozzle with a pintle tip needle and the injection pressure was 147 bar.
