Experimental Investigation on Performance and Emission Characteristics of a Diesel Engine Run on Biomass Derived Fuel Blends

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. A variety of organic materials, including plants, algae, and biowaste, are used to make biodiesels. In order to support industrial aspects in India, the current work proposes to study the engine behavior of a single cylinder DI diesel engine using bio-fuel made from Jatropha oil and waste derived fuel. The combustion, performance, and emission characteristics of a four-stroke, air-cooled, single-cylinder, direct-injection diesel engine operating with the three emulsions were assessed through experiments. The experiments' outcomes were contrasted with diesel operation. According to the test results, KME-WPO emulsions exhibit high peak cylinder pressures and a reduced ignition delay. Higher exhaust gas temperatures and reduced specific energy consumption are characteristics of the KME and KME-WPO emulsions. The findings also show that, when compared to diesel fuel at full load, the nitric oxide emissions from KME and WPO5, WPO10, and WPO15 emulsions are approximately 16%, 10.8%, 2.2%, and 0.5% higher, respectively.
