Global pollution levels in many applications will now be at danger because of the growing need for fuel. CR hydrogen is an alternative to diesel fuel and a possible supply of unspent fuel in India. Using hydrogen as a sole fuel in a direct-injection diesel engine has been tested for its practicality. One-cylinder diesel engine with air cooling was adapted to operate as a low-heat-rejection engine. To protect the engine's combustion chamber, partially stabilized zirconia ceramic components were employed. A single-cylinder compression ratio (CR) engine with varied CR Hydrogen fuels will be studied to determine the optimal performance and emission characteristics. There was a comparison of diesel fuel performance measures such as specific fuel consumption (SFC), brake thermal efficiency (BTE), and emissions of HC, CO, Smoke, and NOx. A compression ratio of 17.5 for hydrogen fuel demonstrates higher performance and reduced emissions, which is quite similar to neat diesel fuel in terms of performance and emissions levels. Different compression ratios (15.5, 16.5, and 17.5) were tested in order to determine the optimal combination for running the engine on hydrogen mixes. Furthermore, the increase in compression ratio raises the BTE, reduces the SFC, and lowers emissions without any engine design changes
