New Federal-Mogul Powertrain high thermal conductivity seats and guides keep engine valves cooler; improved combustion, lower emissions

Green Car Congress

Federal-Mogul Powertrain will debut new materials for valve seats and guides with improved thermal conductivity at the 2017 IAA Show in Frankfurt, Germany next month. For exhaust valve head alloys, every 20°C reduction in temperature negates the need for an upgrade to the next, more expensive alloy specification.
