Experimental Study on the Performance and Emission Parameters of a Dual Fuel Diesel Engine

Mechanical

Concerns about health risks from harmful emissions, rising fuel prices, and fuel depletion have all been linked to the use of fossil fuels in internal combustion engines. The use of acetylene as an alternative fuel has drawn the attention of numerous researchers due to its advantages, including ease of availability, improved combustion, and a decrease in harmful emissions. A diesel engine operating in dual fuel mode with a constant CR of 17.5 and acetylene flow rates ranging from 1 LPM to 3 LPM was used for the current experimental study. When performance parameters and emission were taken into account, the lower amount of biodiesel and 4 LPM of acetylene produced better results. Brake thermal efficiency and mechanical efficiency were found to have increased by 19% and 30%, respectively. Additionally, a 19% decrease in brake-specific energy consumption was observed. Although CO2 and HC emissions dropped by 4% and 56%, respectively, higher CO and NOx emissions were noted at high load levels and low CR, as other researchers have found in related studies.
