Patil, A., Raibagkar, H., and Patil, C., "Theoretical Approach for Degassing Tank Design," SAE Technical Paper 2015-01-2793, 2015, doi:10.4271/2015-01-2793.
Now-a-days there is a trend of engine downsizing driven by emission norms and a race to deliver engine power and torque similar to those which are developed by multi cylinder engines. Thus, engines are running on higher temperatures making the engine cooling system vulnerable. Degassing tank is one of the solutions to resolve the problems pertaining to engine cooling system. The main function of degassing tank, also known as de-aeration tank, hot bottle, expansion tank is to remove the entrapped gases/air from the engine cooling system.
