Emission in Internal Combustion Engines can be achieved through fuel modification, combustion control or by outlet gas treatment. Comparatively, the third approach is easy since there is little or no need of modifying the engine. Similar one technique is selective catalytic reduction (SCR). In this paper, simultaneous attempt is made to control the NOx pollution through fuel modification and exhaust treatment techniques. Plastic pyrolysis oil (PPO) as alternate fuel added with 100, 200, 300, 400 and 400 mg/l of Butylated hydroxyanisole (BHA) antioxidant and injection of constant quantity of aqueous solutions of urea in the tail pipe fitted with Vanadium-based nodule as SCR catalyst was carried out on a 4 stroke, mono barrel CI power train. The results reveal that with urea vaccination conforming to 8–9% of the fuel, the NOx emission dropped by 69% with no significant drop in BTE and rise in other pollutants.
