Fuel Additive that Cuts Emission and Increases Brake Power in a Small Bio-Fuel Diesel Engine 2006-32-0074

This paper presents experimental test results of a diesel engine using additive added bio Diesel oil obtained from palm oil. The test results obtained are brake power, specific fuel consumption (SFC) and exhaust emissions. In addition, anti-wear characteristics of fuel's contaminated lubricants were observed using a tribometer test. A computer control dynamometer-engine test bed was used to measure engine brake power and SFC at half throttle condition with speed range of 1000 rpm to 4000 rpm. The emission test was done with dynamometer fixed load of 50 Nm and constant engine speed of 2250 rpm. A total of three fuels or 100% diesel fuel (B0); 20% palm oil diesel (POD) and 80% B0 (B20); and B20 with X% additive (B20X) were selected for this investigation. The B20X is the additive added bio Diesel oil where X is the percentage (in this investigation X=1% of B20) of additive in B20 fuel. Anti wear characteristics in terms of coefficient of friction, wear scar diameter and flash temperature parameter (FTP) of fuel's contaminated lubricants were measured using a tribometer test. It was found that B20X fuel showed better overall performance such as cut emissions and increased engine brake power as well as increased anti-wear characteristics as compared to other test fuels. The specific objective of this investigation is to improve the performance of B20 fuel with an antioxidant additive. Detailed results have been presented with discussions.
