AI Technical Summary

Technical Problem

The existing hydrogen fuel internal combustion engines are prone to premature combustion or backfire due to the compression process and combustion process in the same confined space, resulting in a lower energy utilization rate.

Method used

A hydrogen fuel internal combustion engine with a scroll structure is designed. The first moving scroll is driven by a motor to rotate and rotate, so that the air is compressed in the moving scroll and enters the combustion chamber and fully mixes with hydrogen, and is ignited by the ignition device in the combustion chamber, and the mixed gas expands and does work. The burned high-temperature and high-pressure exhaust gas enters the expansion chamber to do work, recover the energy of the exhaust gas and improve the energy utilization rate.

Benefits of technology

By recovering the energy of exhaust gas, maximizing energy utilization, improving the efficiency of hydrogen fuel internal combustion engines, and avoiding the problems of premature combustion or backfire, enhancing motivation and economicality.
