Inside the wastegate actuator, a spring acts to open the wastegate, and oil pressure acts to close the wastegate. On the oil output side of the wastegate actuator sits the density controller, an air-controlled oil valve which senses upper deck pressure and controls how fast oil can bleed from the wastegate actuator back to the engine. As the ...
Regardless of the effectiveness of the boost controller, wastegate actuator springs that are too soft can cause the wastegate to open before desired. This due to the exhaust gas backpressure pushing against the wastegate valve itself, causing the valve to open of the actuator at all. Therefore, there is an upper limit to the effectiveness of a ...
Some variable-geometry turbochargers use a rotary electric actuator to open and close the vanes, [38] while others use a pneumatic actuator. If the turbine's aspect ratio is too large, the turbo will fail to create boost at low speeds; if the aspect ratio is too small, the turbo will choke the engine at high speeds, leading to high exhaust ...
This design has a lower flow rate compared to VNT types so a wastegate may be incorporated with this design. [5] VGTs may be controlled by a membrane vacuum actuator, electric servo, 3-phase electric actuation, hydraulic actuator, or pneumatic actuator using air brake pressure. Unlike fixed-geometry turbines, VGTs do not require a wastegate. [6]
A vacuum hose connected to the intake manifold downstream of the throttle provides a reference pressure for the blowoff valve.. When the throttle is open, the air pressure on both sides of the blowoff valve's piston is equal, therefore the spring holds the valve closed.
Wastegate control and anti-lag; Theft prevention by blocking ignition, in response to input from an immobiliser; In a camless piston engine (an experimental design not currently used in any production vehicles), the ECU has continuous control of when each of the intake and exhaust valves are opened and by how much.

Over the past four years, the Trump administration has destroyed or distorted vast swaths of information vital to public life and safety. This is an account of the damage.
Compact twin direct-mount turbos with integrated exhaust manifold and electronic wastegate actuator; Twin water-to-air charge coolers with one or two water pumps for the 300 hp (224 kW) and 400 hp (298 kW) variants, respectively; Electronically controlled variable displacement oil pump; Intake: electronic Variable valve timing Control (VTC)
