An engine air shutoff valve system with an improved sensor that facilitates a position detection of the shutoff valve is disclosed. The air shutoff valve system may include a shutoff valve, an indicator, and at least one solid-state proximity sensor. The shutoff valve is moveable between an open and closed position. The indicator is operatively coupled to the shutoff valve. The indicator is movable between a normal state and a tripped state in respective correspondence with the open and closed positions of the shutoff valve. At least one solid-state proximity sensor can be configured to detect when the indicator is in the tripped state.

System and method implementing air shutoff position detection strategy

A thermal management system for an engine is disclosed. The thermal management system may have a first heat exchanger situated to cool air directed into the engine, a pump configured to pressurize a fluid directed through the engine, and a second heat exchanger situated to transfer heat absorbed by the fluid to air directed into the engine. The thermal management system may also have a heater configured to provide supplemental heat to air directed into the engine.

Engine system having cooled and heated inlet air

A thermal management system for an engine is disclosed. The thermal management system may have a first hydraulic circuit configured to circulate a fluid through the engine. The thermal management system may also have a second hydraulic circuit pressurized by the engine to heat the fluid during operation of the engine.
