Reduction and mitigation strategy of carbon dioxide emissions from internal combustion engine: An engine development initiative for sustainable environment

This study reports various methods to reduce and mitigate the CO2 emissions from internal combustion engines. In order to achieve this, the gasoline fuel is replaced with Gasoline-Methanol blend of 5%, 10% and 15% of methanol by volume. Then the emissions and performance tests are carried out to catch CO2 emissions from a spark ignition engine operating in different combinations of torque (2Nm, 3Nm and 5 Nm) and speed (500 rpm, 1000 rpm and 1500 rpm). In order to further mitigate the CO2 emission, four different design mufflers are manufactured and replaced for testing to see the effect on CO2 emissions.
