Turbocharger wastegate is to limit the supercharging pressure of turbocharger and prevent the damage of engine parts caused by extreme high inlet pressure and combustion pressure. Wastegate is connected to turbine shell by a rod and is pressed by diaphragm spring to close. The supercharging pressure in inlet pipe acts on diaphragm spring. When the supercharging pressure reaches to the maximum extreme, it will push diaphragm spring and open wastegate in turn, which makes part of exhaust gas not go through turbine impeller and further limits the rotating speed of turbocharger axis and supercharging pressure.

Tonglint can provide a variety of wastegate products and is able to create and process in accordance with client’s sample and drawing.

Clients requiring wastegate are advisable to offer model and assembly no. of products, or provide drawing or sample.
