The present work aims to achieve simultaneous reduction of NO and smoke emission using waste tire pyrolysis oil (TPO) a third-generation fuel along with cetane improver namely diglyme (DGE) in a twin cylinder CI engine used in tractors. The solid waste tire disposal is getting much attention due to the environmental and health effects to humans. One of the methods to recycle used tire is to convert it to useful fuel to replace diesel in CI engine. Fuel derived from waste tire has comparable calorific value compared to diesel. TPO possess high viscosity and low cetane index causing improper atomization and increased ignition delay. This property of TPO reduces brake thermal efficiency (BTE) with higher NO and soot emissions. BTE for TPO is reduced by blending cetane improver, namely diglyme which subsequently improves the BTE along with reducing NO and smoke. The tests were conducted at constant speed of 1500 rpm with constant fuel injection pressure and timing. The tests were conducted at various load conditions corresponding to 25, 50, 75 and 100% of maximum brake power (BP). DGE was blended 10 and 20% with TPO on volume basis. NO emission increases from 1413 ppm for diesel to 1565 ppm for TPO and reduces to 1350 and 1235 ppm for TPO + DGE10 and TPO + DGE20 at 100% load. Smoke opacity increases from 62% for diesel to 70% for TPO and reduces to 67 and 63% for TPO + DGE10 and TPO + DGE20. TPO + DGE20 reduces maximum NO and smoke emission but brake thermal efficiency (BTE) is less due to high latent heat of vaporization. Hence, TPO + DGE10 is identified as optimum blend to simultaneously reduce NO and smoke emission with improved performance. |
