The low exhaust heat flow of pem fuel cells compared to the internal combustion engine ic means that, despite higher efficiencies, the heat rejected to the cooling system is higher in fuel cell vehicles. Cooling systems of ic engines c if we employ water cooling system, then engine need not be provided at the front end of moving vehicle. A read is counted each time someone views a publication summary such as the title, abstract, and list of authors, clicks on a figure, or views or downloads the fulltext. That is why we need a more advance engine cooling system that can achieve proper cooling of the engine without any compromise with the aerodynamics shape of vehicle. The other one is low pressure welding in which oxygen is supplied from high pressure cylinder but acetylene is generated by the action of water on calcium carbide and supplied at low pressure. Disadvantages a it depends upon the supply of water. The temperature of the burning gases in the engine cylinder reaches up to 1500 to 2000c, which. In summary, evaporative cooling is the process of removing heat from a surface due to the evaporation of water. Evaporative cooling system of internal combustion engine.
