Abstract: The scaled model experiments are beneficial for reducing time， cost and energy consumption in new marine diesel engine development. Firstly， the history of diesel combustion similarity theory is reviewed， and three scaling laws based on the single value conditions for diesel combustion similarity are summarized. Then， the latest theoretical and experimental researches on similarity of spray mixture formation processes are emphasized. Finally， the technical challenges that need to be further solved in the scaled model experiments are proposed. The theory system of diesel spray combustion similarity established in this paper is helpful to formulate scientific and reasonable experimental specifications for the scaled model experiments， and promote the rapid development of marine diesel engines.
