About CAHEMA
The project Concepts of ammonia/hydrogen engines for marine application (CAHEMA) investigates innovative injection and combustion strategies using ammonia and hydrogen in combination, to achieve Reactivity Controlled Compression Ignition (RCCI) and Direct-injection dual fuel stratification (DDFS) for marine engines with these fuels. The project combines advanced computational models and experimental techniques to develop these engine concepts, and assess the potential environmental,…
