In this research, injector, cleaner and camphor were blended with premium motor spirit (PMS). The physicochemical properties and eff ects on the performance and exhaust emission levels of spark ignition engines were investigated. Samples with injector cleaner showed the best physicochemical properties relative to the sole petrol and camphor blended samples; these specimens had densities of 0.72706 kg/m2 (I5), flashpoints of 47 °C for I5, I10, and I15 and 48 °C by I25, and viscosities of 1.7. A performance analysis showed that I25 at 3 Nm had specific fuel consumption levels of 45.51 kgkwh-1 and 27.2 kgkwh-1, which were the best recorded among all the samples; additionally, the sample I25 showed the lowest emissions of CO and CO2 at 0.2% and 0.13% at 3 Nm and 6 Nm, respectively, for CO emissions and at 1.22 and 1.47% at 3 Nm and 6 Nm, respectively, for CO2 emissions. Concerning NOx emissions, sample I25 showed the best results, with the highest NOx emission reductions of 312 and 342 ppm at 3 and 6 Nm engine torques, respectively. With this information, it was concluded that cleaner injector blends were better than camphor blends. [ABSTRACT FROM AUTHOR] |
