Phase change material is widely used in heat storage applications. PCM is used in this research to increase the efficiency of a catalytic converter by holding the temperature above the recommended temperature. The conversion rate is extremely poor at lower temperature or below the light off temperature, and practically it is zero. Part solidification converts the heat from solid to liquid, returning the heat and return the heat to substrate by partial solidification. In this paper, the results of experimental experiments were investigated under various loading conditions, including experimental testing. For the complete melting period of the PCM, the contours of a melting fraction of PCM at a regular interval for various loading conditions are shown.
By investigating the exhaust emissions of catalytic converters, this research seeks to find a catalytic converter made from a catalytic combination of brass wire and copper wire in the shape of spiderwebs. As a catalyst for catalytic converters, the combined catalyst of brass wire and copper wire in the form of a cobweb is most commonly used. The results of emissions analysis revealed that catalytic converters made from a combination brass wire and copper wire in the shape of a spider's web could reduce HC and CO2 emissions by a significant decrease in HC and CO2 emissions, as well as the increase in CO2 emissions. The reduction in CO gas emission reduction was 4. 5 ppm or 26. 5 percent compared to the value without using a catalytic converter. In comparison to the previous value without using a catalytic converter, CO 2 gas emissions increased by 4. 3 ppm or 9. 7% compared to the value without using a catalytic converter, due to the addition of oxygen in the oxidation process.
Many have switched to petrol vehicles due to the increasing number of traffic on our nation's highways, posing a significant threat to the climate due to dangerous emissions, and the refueling availability and poor maintenance of diesel fuel vehicles have prompted many to opt for petrol cars. According to the study, the nano-ZnO coated catalytic converter helped reduce the CO, CO 2, HC, and NO x emissions by 41. 3%, 48. 2%, and 46. 7%, respectively.
