| Abstract:The ignition and combustion characteristics of fuel have a significant impact on the combustion concept and parameter changes of engines using zero-carbon fuels.The analysis focuses on the effect of ammonia and hydrogen on excess air coefficient，combustion parameters on turbochargers matching with engines.It is concluded that ammonia fuel needs a larger turbine area，while hydrogen fuel needs a compressor with much higher pressure ratio and a very small turbine，which is challenging to matching the zero-carbon fuel with the existing turbocharger portfolio. |
