最近,技术刊物的一些文章和工业及研究机关的科技人员都对柴油机燃烧室零件采用具有极低导热率的材料的讨论重新发生了兴趣。这种兴趣的产生看来是由于期望通过采用这种材料能大大改善燃油的经济性。这些燃烧室零件可以整个的用一种材料制成,或者制成组合体,在邻接燃气的部分厚厚敷一层导热率低的材料。可以采用的材料有钛和氮化硅(用于整体式和组合式),氧化铝
Recently, some articles in technical publications and scientific and technical personnel in industrial and research institutes have renewed their interest in the discussion of the use of materials with very low thermal conductivities in diesel engine combustor parts. This interest appears to stem from the expectation that the economy of fuel will be greatly improved through the use of this material. These combustion chamber components can be made entirely of a single material or combined to provide a thick layer of low thermal conductivity adjacent to the gas. Materials that can be used are titanium and silicon nitride (for monolithic and modular), aluminum oxide
