A vehicle including an engine; a turbocharger, an intake air flow path of the vehicle defined from air entering the vehicle, passing through the compressor, and flowing into the engine air inlet; a coolant container assembly; a temperature sensor configured for determining a temperature in the intake air flow path; and a controller configured to selectively cause cooling liquid to flow from the coolant container into the intake air flow path. A method for managing engine air intake temperature or piston temperature of a turbocharged vehicle including: sensing a temperature of fluid within the air intake flow path, determining an estimated piston temperature; and in response to the estimated piston temperature and/or the temperature of the fluid being above threshold temperatures, causing an amount of cooling liquid to flow from a coolant container to the air intake flow path.

System and method for managing piston temperature in a vehicle

A valve for use in an engine exhaust conduit. The valve includes a base portion and a body portion extending from the base portion. The base portion is configured for pivotably mounting the valve within the engine exhaust conduit. The base portion defines a valve pivot axis. The valve is pivotable about the valve pivot axis during use. The body portion has an upstream side and a downstream side opposite the upstream side. The upstream side is exposed, during use, to fluid flow in the engine exhaust conduit. The body portion has a generally pointed shape defining a rounded tip at a location of the body portion furthest from the base portion in a length direction of the valve. The length direction of the valve is generally perpendicular to the valve pivot axis.
