jackets, in which liquid coolant is circulated and the coolant takes away the excess heat. The excess heat is then dissipated by a heat exchanger or radiator using air flow. Turbine engines use secondary airflow to cool the inside components ... many of the exterior components. Reciprocating Engine Cooling Systems An internal-combustion engine is a heat machine that converts chemical energy in the fuel into mechanical energy at the crankshaft. It does not do this without some loss of energy…

Glossary
current in the paralleling circuit that forces the generators to share the electrical load equally. Ethylene dibromide. A chemical compound added to aviation gasoline to convert some of the deposits left by the tetraethyl lead into lead bromides. These bromides ... used as a coolant for liquid-cooled engines and as an anti-icing agent. Eutectic material. An alloy or solution that has the lowest possible melting point.
