Boost Controller - Electronic Boost Control - Control Details
... on its way to the reference port on the wastegate actuator diaphragm in order to (on occasion ) under report boost pressure in such a way that the wastegate permits a turbocharger to build more ... a boost-control solenoid valve lies to the wastegate under ECU (engine control unit) control ... air bleeds out of the T in the manifold pressure reference line to the wastegate ...
Boost Controller - Electronic Boost Control - Limitations and Disadvantages
... Even with an electronic controller, actuator springs that are too soft can cause the wastegate to open before desired ... gas backpressure is still pushing against the wastegate valve itself ... This backpressure can overcome the spring pressure without the aid of the actuator at all ...
Boost Controller - Manual Boost Control
... and pneumatic control to allow some pressure from the wastegate actuator to escape or bleed out to the atmosphere or back into the intake system ... This can be as simple as a T-fitting on the boost control line near the actuator with a small bleeder screw ... allow air to bleed out of the system, relieving pressure on the wastegate actuator, thus increasing boost levels ...
Boost Controller - Electronic Boost Control
... is present, which is to control the air pressure presented to the wastegate actuator ... can achieve the goal of reducing pressure pushing against the wastegate ... the control lines, reducing the load on the wastegate actuator ...
Wastegate - Control - Pneumatic
... The simplest closed-loop control for a wastegate is to supply boost pressure directly from the charge air side to the wastegate actuator ... outlet, charge pipes, or intake manifold to the nipple on the wastegate actuator ... The wastegate will open further as the boost pressure pushes against the force of the spring in the wastegate actuator until equilibrium is obtained ...
