A review of comparative studies on injection strategies of spark ignition internal combustion engines with ammonia-hydrogen blends

Ammonia-hydrogen fuels are promising for low-carbon spark-ignition (SI) engines, but their performance strongly depends on fuel-delivery and combustion-control strategy. This review compares port fuel injection (PFI), direct injection (DI), PFI + DI, ammonia-hydrogen dual direct...
