Operating and Thermal Efficiency Boundary Expansion of Argon Power Cycle Hydrogen Engine

The efficiency enhancement of argon power cycle engines through theoretical means has been substantiated. However, the escalation in-cylinder temperatures engenders abnormal combustion phenomena, impeding augmentation compression ratios and practical efficiency. This study presents a comprehensive investigation employing experimental simulation techniques, aiming to extend boundaries thermal operational capabilities for hydrogen-powered engines. impact hydrogen direct injection, intake boost, port water injection is evaluated in conjunction with an engine. particularly at engine speed 1000 rpm, significantly increases indicated mean effective pressure from 0.39 MPa 0.72 Mpa, surpassing performance injection. Manipulating timing results formation stratified mixture, effectively attenuating rate, resolving issue excessively rapid within Ar/O2 environment. implementation super lean combustion, combined intake-boosting, achieves maximum gross 57.89%. Furthermore, proves be measure against knock, broadening range intake-boosted conditions. Notably, recorded group under conditions reaches 59.35%.
