Abstract
A valve assembly and method for controlling flow of gases through a passage between an engine crankcase and an engine intake manifold is provided. The method includes decreasing a flow of gases through the passage between the crankcase and the intake manifold when a temperature of the gases is greater than a predetermined temperature.
Claims10
A method for controlling flow of gases through a passage between an engine crankcase and an engine intake manifold, the method comprising:
- decreasing a flow of gases through the passage between the crankcase and the intake manifold when a temperature of the gases is greater than a predetermined temperature.
A method for controlling flow of gases through a passage between an engine crankcase and an engine intake manifold, the method comprising:
- controlling a flow of gases through the passage between the crankcase and the intake manifold when a temperature of the gases is less than a predetermined temperature;
- and,
- decreasing said flow of gases through the passage when said temperature of the gases is greater than a predetermined temperature.
A valve assembly for controlling flow of gases through a passage between an engine crankcase and an engine intake manifold, comprising:
- a housing configured to be coupled with the passage;
- and,
- a flow control device disposed in said housing, said device decreasing a flow of said gases through said housing when a temperature of said gases is greater than a predetermined temperature.
A control system for controlling flow of gases through a passage between an engine crankcase and an engine intake manifold, the system comprising:
- a temperature sensor generating a first signal indicative of a temperature of said engine;
- a valve assembly having a housing and a flow control device disposed in said housing, said housing being configured to be coupled with the passage, said flow control device being configured to decrease a flow of said gases through said housing responsive to a second signal;
- and,
- a controller operably connected to said temperature sensor and said valve assembly, said controller generating said second signal when said first signal indicates said temperature is above a predetermined temperature.
