       In the current state, the incredible rise of the cost of Diesel fuel, stringent emission regulations, and the reduction of petroleum reserves are driving us to search for new sources of energy. Fossil fuels are the cheapest and the majority abundant source for petroleum and thus lead to the growth of gazillions of petroleum-established products. So, the NOX emission was raised. The work within this project mainly focuses on the act of blended Pyrolysis oil with Diesel fuel and toluene oil which was used in a single-cylinder, Four-stroke Diesel Engine. The Pyro oil was extracted during the pyrolysis process as of the Mosambi Peel biomasses.  All the bio-oil properties were studied with the fuel blends used within this experiment were MPOT5 (5%MPO+5%TU+ 90D), MPOT10 (10%MPO+5%TU+85%D) and MPOT15 (15% MPO + 5%TU + 80% D). Characteristics of fuel for Diesel, MPOT5, MPOT10, and MPOT15 are analyzed.  The blending test of Pyrolysis oil and toluene was done by mixing diesel fuel by volume. The flashpoint, fire point, Viscosity, Density of oils was observed.  The entire blended pyrolysis fuel was tested in a 1500 rpm single-cylinder water-cooled Diesel Engine for testing their performance like blend fuel. The test results show the performance of all MPOT5, MPOT10, and MPOT15 associated with diesel fuel. The highest power output of the brake thermal efficiency is found to be 31.2% with MPOT5 and whereas it was 30.5% with BD respectively. There be a narrow decline for the Smoke and NOx Emissions and HC and CO emission slightly which reduces the chances of MPOT5 while fuel compared to BD at all Power outputs.
