Description
本発明は、かかる事情に鑑みてなされたものであり、燃焼効率を向上させることができるアンモニアエンジンを提供することを目的とする。
本発明のアンモニアエンジンによれば、水素ガス生成装置により発生した高圧の水素ガスを、高圧下の燃焼室内に供給することができるため、燃焼室内のアンモニアは可燃性ガスである水素ガスとともに燃焼することで、アンモニアの燃焼効率を向上させることができる。
この場合、シリンダのピストンが圧縮上死点に達するときに燃焼室内に水素ガスを供給することができるため、ポンピングロスを効果的に低減することができ、アンモニアエンジンの熱効率を向上させることができる。
この場合、高圧の水素ガスを生成するための専用のアンモニアを別途用意する必要がないので、エンジン全体の構成を簡素化することができる。
図1は、本発明の一実施形態に係るアンモニアエンジンの構成を示す模式図である。図1において、本実施形態のアンモニアエンジンは、液体アンモニアを燃料とするエンジン本体1と、液体アンモニアを貯留するタンク2と、液体アンモニアを用いて高圧の水素ガスを発生させる水素ガス生成装置3と、生成された高圧の水素ガスをエンジン本体1に供給する水素ガス供給装置4とを備えている。
MH(固体)+NH3(液体)→MNH2(固体)+H2(気体)
ここで、Mは、一価の軽金属元素である。
