Performance and Emission Characteristics of Diesel Engine with the Biodiesel-Acetylene Addition using Dual Fuel Mode

Abstract

This research work investigated the diesel engine performance using 20% Pongamia grease methyl ester through the effect of different flow rates of acetylene using dual-fuel technique. Acetylene be inducted within the intake various at the flow rates of 1lpm, 2lpm, 3lpm and 4lpm along with air. Initially a test was conducted by diesel fuel along with POME20 on different loads. Then the experiment was carried out with POME20 with different flow rates of acetylene. Addition of acetylene increased the brake thermal efficiency (BTE) among POME20 at all acetylene flow rates on 100% load. The results showed that the BTE was enhanced via regarding 1–3.4% at knock-limited acetylene shares at 100% load. The engine emits higher NOx emission for POME20 without acetylene share and then it is additional improved with the adding up of acetylene shares, while the smoke opacity was reduced by 47% with acetylene addition at complete load. Here is a decrease in HC as well as CO emissions were experiential through an acetylene orientation along with POME20. Finally, it is suggested that the poor presentation as well as emissions connected through biodiesel into a diesel engine can be improved through the induction of acetylene with 4lpm flow rate in the intake various by dual fuel technology.
