The goal of this research is to analyze the effects of a partial thermal barrier coating on piston temperature distribution in homogeneous charge compression ignition (HCCI) engines, which are investigated using La2Zr2O7 nanocoating with 1 mm thickness for numerical analysis. The thermal assessments of both conventional and coated pistons were performed using ANSYS V16. Engine testing was conducted on a single-cylinder, water-cooled CI engine for both the coated and conventional casings. According to the analytical results, the coated piston component’s surface temperature increased to 53 °C, which increased the temperature of the air–fuel mixture in the crevice and wall quenching zones. As a result, cold start HC emissions dramatically drop without impacting engine performance compared to normal engines. The maximum HC emission reduction over the standard engine was 43.2%. |
