在单缸柴油机上进行了活塞顶和气门表面涂覆氧化钇稳定氧化锆（YSZ）涂层的试验研究。将0.2 g L-1氯化铁（FeCl 3）作为催化剂添加到涂覆和未涂覆发动机中的柴油燃料中。结果表明，与未涂覆YSZ的柴油机相比，FeCl 3与柴油机的混合制动热效率提高了2.7%，燃油消耗率降低了8.3%。所选用的热障涂层改善了补燃阶段的燃烧，有效地利用了进气。一氧化碳、碳氢化合物和烟雾不透明度等排放量随着氧化氮和二氧化碳排放量的增加而减少。
In the present investigation, the engine performance and emission characteristics of a single cylinder diesel engine with yttria stabilized zirconia (YSZ) coating on piston crown and valves were studied. The 0.2 g L−1of ferric chloride (FeCl3) as catalyst was added into the diesel fuel in both coated and uncoated engines. The results indicated that FeCl3with diesel in a YSZ coated engine increased the brake thermal efficiency by 2.7%, and reduced brake specific fuel consumption by 8.3% as compared to standard diesel mode in uncoated engine. The selected thermal barrier coating improved the combustion in afterburning stage leading to effective use of intake air. Emissions such as carbon monoxide, hydrocarbons and smoke opacity were reduced with an increase in emissions of nitrogen oxide and carbon dioxide.
