Paper Title**：
Estimation of Fuel Components for Ignitability Index of Marine Fuel - Estimation Method and Its Application to Multi-component Fuel (Residual Marine Fuel) -

About awarded research**：
The CCAI (Calculated Carbon Aromaticity Index) is calculated from the density and kinematic viscosity of a marine fuel to evaluate the ignitability of the fuel. The CCAI is a useful index for marine residual fuel with few measurable physical properties. However, when a fuel ignitability test is performed using the FCA (Fuel Combustion Analyzer), the measured ECN (Estimated Cetane Number) does not always correlate with the calculated CCAI. In this study, we proposed a method for modeling real fuels and estimating the proportion of hydrocarbons in these model fuels.

About awarded research**：
This paper was presented at CIMAC (International Council on Combustion Engines), the world's highest level international conference on medium and large sized internal combustion engines, held once every three years, and was extremely well received. The content of the paper is related to basic research on ammonia-fueled low-speed, two-stroke diesel main engines in the development of ammonia-fueled ships as a part of NEDO's Green Innovation Fund for the Development of Next-Generation Ships. NMRI, in collaboration with Japan Engine Corporation, has developed a new constant-volume combustion device that can simulate actual engine conditions, and has paved the way for the development of ammonia engines and the promotion of ammonia-fueled ships through basic research such as visualization and analysis of ammonia spray flames by the stratified ammonia injection system.
