Effects of different piston combustion chamber heights on heat transfer and energy conversion performance enhancement of a heavy- duty truck diesel engine

Xiaohuan Zhao et al.

Summary: This study investigates the heat transfer and energy conversion characteristics of three types of pistons based on a heat load prediction model for diesel engine pistons. It explores the thermal energy conversion effects of pistons on the performance of heavy-duty truck engines, including air-fuel ratio, intake flow, exhaust temperature, and fuel consumption. The results show that increasing the piston combustion chamber height leads to higher temperatures and heat flux in the piston. The findings also reveal significant variations in temperature and heat flux among the different piston types. Piston-18 demonstrates improved efficiency and heat energy conversion capability with a larger air-fuel ratio, intake flow, lower fuel consumption, and exhaust temperature. Additionally, optimizing the piston chamber height can enhance heat transfer and energy conversion performance.
