Abstract:
Systems and methods are provided for managing temperatures associated with a flow control assembly, such as a throttle loss recovery assembly. One exemplary method of operating a flow control assembly generating electrical energy in response to a bypass fluid flow influenced by an orientation of a flow control valve involves operating the flow control assembly to deliver the electrical energy to a vehicle electrical system and automatically adjusting operation to increase heat generation at the flow control assembly in response to a temperature condition, such as a potential icing condition or a cold start condition.
Abstract:
Systems and methods are provided for managing temperatures associated with a throttle loss recovery system. One exemplary system includes a flow control assembly for recovering energy from a fluid bypassing a flow control valve based on an orientation of the flow control valve, a conduit providing fluid communication with the flow control assembly for the portion of the fluid flow bypassing the flow control valve, and an electronics assembly including an electronics module coupled to the flow control assembly. At least a portion of the electronics assembly is in fluid communication with the portion of the fluid flow bypassing the flow control valve, thereby allowing for heat transfer between the electronics assembly and the fluid bypassing the flow control valve.
Abstract:
An electro-pneumatic actuator for a waste gate includes an electric actuator to impart linear motion to an actuator shaft, and a pneumatic chamber defining a passage extending therethrough, the actuator shaft extending through the passage, the pneumatic chamber being sealed with respect to the actuator shaft. A piston is disposed in the pneumatic chamber and arranged for movement in the pneumatic chamber, the piston being affixed to the actuator shaft such that the actuator shaft and the piston move together as a unit. There is a port into the pneumatic chamber for feeding a gas into the pneumatic chamber or exhausting the gas therefrom so as to exert a pressure force on the piston and thereby provide a pneumatic assist to the force exerted on the actuator shaft.
