Waste Tire Oil Fueled CI Engine Combustion Argumentation for Emission Reduction by Butylated Hydroxy Anisole (BHA) Antioxidant

Abstract

In the world, transport vehicle usage is increasing every day. Corresponding wastes of their used tire become a challenge to the environment as non-biodegradable waste. This waste tire can be used to derive the waste tire oil with distillation for engine application. This oil cannot used as neat fuel for the engine. They were blended with diesel support to reduce the total diesel usage. The base fuel is a 20% waste tire oil blend with 80% diesel (D80WTO20). Butylated hydroxy anisole (BHA) antioxidants of 250–1000 ppm with a 250 ppm deviation were added with a D80WTO20 blend for testing in a 5.2 kW CI engine. The D80WTO20 blend has lesser performance and higher emissions than diesel. The increase of BHA concentration in the fuel enhances the results. The maximum concentration of BHA (1000 ppm) used in D80WTO20 is obtained BTE of 32.92%, which is higher than diesel and the blend. The same combination has lesser BSFC (0.247 kg/kW-h), NOx (1406 ppm), smoke (51.68%), HC (61 ppm), and CO (0.224%) emission D80WTO20 blend than because of the better oxidation, the catalytic reaction produced improved combustion. Therefore, the 1000 ppm of BHA antioxidant mixed D80WTO20 blend can be the alternate fuel for the CI engine with lesser emission and improved performance.
