<p>The world greatly relies on the usage of liquid fuels for its energy needs, especially in the transportation sector, which is very high in developing countries. In countries like India, diesel fuel is mainly used for all its transportation requirements, (considering its higher efficiency) which also leads to higher pollution. Many researches are being conducted to find a replacement for diesel fuel. In which biodiesel is considered to be a potential replacement for diesel. But the challenges like higher viscosity, lower calorific value, higher NOx emission stands as a huge barrier. To overcome this, this study proposes the usage of a low viscous biofuel, which has a higher calorific value close to diesel. And as a measure to reduce NOx emission, exhaust gas recirculation (EGR) technique is used in this study. A single cylinder, constant speed, water cooled stationary engine setup is used for this study. 20% of pine oil is blended with diesel and 10ml of 1,4, dioxane additive is added. These blends are tested in the engine for different load conditions (0, 25, 50, 75 and 100%) with and without 10% EGR. The results showed that the usage of pine oil had a slight negative effect on the performance characters, but reduced CO, HC and Smoke emissions significantly (15.94, 17.04 and 2.47% respectively). The 10ml of 1,4, dioxane further enhanced this reduction (32.61, 28.15 and 4.36% respectively). The 10% EGR usage, though had a negative effect on both performance and emission characters, managed to reduce NOx emissions significantly (11.53%). This study provides an integrated way to overcome the challenges seen in the usage of biodiesel with a low viscous biofuel and exhaust gas recirculation technique.</p>

ASME 2021 Energy Sustainability (ES2021)

Supporting the need among researchers worldwide for additional online and multimedia content, ASME now offers the ASME Conference Video Collection. This platform will collect and provide long-term access to conference presentation videos, encompassing all technology areas within ASME's technical conference and events program. About 30,000-40,000 engineers across all mechanical engineering and related disciplines participate in ASME conferences each year. This includes authors of approximately 6,000 to 8,000 technical papers published by ASME, the majority of whom also submit video presentations for our virtual conferences. The video collection will be available as an add-on to existing product packages or as a separate subscription.
