Numerical investigation of the effect of thermal barrier coating on combustion and emissions in a diesel engine

Yang Wang et al.

Summary: The study shows that increasing the porosity and reducing the thermal conductivity of TBC can increase the gas temperature in the cylinder and exhaust temperature, leading to higher conversion efficiencies of diesel oxidation catalyst (DOC) and selective catalytic reduction (SCR), and lower emissions. However, the specific heat capacity only affects the peak of heat release rate, and thermal efficiency has minimal fluctuation with the increase of specific heat capacity. This research provides guidance for selecting coating materials and improving coating spraying methods, with potential future research directions in the durability of coating materials.

Plasma electrolytic oxidation thermal barrier coating for reduced heat losses in IC engines

Abdelrahman Hegab et al.

Summary: The study focused on developing and testing a new thermo-swing barrier coating to reduce wall heat transfer and increase thermal efficiency in diesel engines. The results showed that applying the optimum coating can improve indicated thermal efficiency under part load conditions while reducing heat transfer during combustion and providing energy savings.
