Abstract: The main aim of the paper is to investigate the, combustion, emission and performance characteristics of blended waste plastic pyrolysis oil (WPPO 5%, 10%, 15% and 20%) with diesel fuel based Homogenous Charge Compressor Ignition (HCCI) combustion engine. The experiments have been conducted on HCCI mode engine by varying the intake temperature (353K, 373K, 393K & 413K). WPPO is used to inject the intake manifold based on port-fuel injection methodology despite the fact of intake-air is heated by utilizing electric-heater for attaining stable HCCI functioning. From outcome results it is observed that the temperature of intake air has more pre-dominant effect on combustion, performance and emissions characteristics. The maximum thermal efficiency of WPPO-diesel fueled HCCI functioning is acquired as 45.12% at 413K with WPPO-5% blended with diesel. Formerly Nox were decrease for all blends and later slightly increases but smoke is negligible. However, the CO and UHC emissions are first increased and then decreased for the HCCI operation.
