Abstract: The present study investigates various methods for reduction of CO₂ emission in a Karanja oil methyl ester (KOME) fuelled single cylinder CI engine. Combustion of KOME emits more CO₂ due to longer carbon chain. The reduction in CO₂ emission was done in three phases. In the first phase, low carbon pine oil (PO) fuel was blended with KOME in equal volume. The results indicated 7% reduction in CO₂ emission for KOME-PO blend compared to KOME. In the second phase, methanol, n-butanol and acetone were blended on 20% volume basis with KOME-PO blend for further CO₂ reduction. Mono ethanol amine (MEA) was injected in the exhaust for achieving minimum CO₂ emission in the third phase. KOME-PO+MEA injection emits minimum CO₂ emission compared to other blends. However, considering NO-CO₂ trade-off, KOME-PO + methanol with amine injection is optimum for simultaneous reduction of both the pollutants.
