Throttle Valve (DK)

A throttle valve is necessary for all diesel engines equipped with a particulate filter system. The throttle valve chokes the intake air to ensure that the necessary increased exhaust-gas temperatures required for regeneration of the particulate filter are reached.
The throttle valve is closed, while the engine is switched off, this reduces the shaking of the engine during the switching off procedure. After the switching off of the engine, the throttle valve is opened again.
