This report proposes a pressurized liquid cooling system for internal combustion engines, which is more effective than other types of liquid cooling systems. The system is designed to regulate pressure during start-up operations and control the heat cooling rate at critical points. The report discusses the methodologies of the new technology and provides background insights into existing technologies. The report also includes analysis and calculations of the system's operational and efficiency measures. The proposed model will improve engine performance by increasing heat capacity, stretching the maximum boiling temperature, and minimizing the lower freezing temperature.
