This document summarizes a research study that investigated the emission characteristics of a spark ignition engine fueled with blends of petrol and kerosene. The study used an experimental setup that included a Honda portable generator, gas analyzer, load bank, and other equipment. Various blends of petrol and kerosene ranging from 20-80% were tested at different loads. The results showed that a blend of 80% petrol and 20% kerosene produced lower levels of NOx and HC emissions compared to other blends. At higher loads, a 20% kerosene blend produced less CO emissions than other blends. Overall, a 80:20 petrol to kerosene blend provided the best balance of engine performance and lowest
