CDI sisselaskekollektori klappide eemaldamine+turbo probleem

[laf1247]

Võiks oma 3,2 cdi klapid ka välja visata. Egri panin kinni juba. Keegi tark võiks lähemalt rääkida miks need klapid seal üldse on ja mida tegema peavad. Oma loogika ütleb mida vähem asju seal seda õhu voolamist takistab seda parem.

A swirl and a charge inlet port (110/19) are provided in the charge air manifold for each cylinder. The charge inlet ports can be closed by means of flaps (110/20). The flaps are connected to each other by means of a linkage, which is operated by the intake port shutoff motor (M55). They are held open by spring force when there is no current.

In the lower rpm and load range all the filling inlet ports are sealed by valves. The complete air mass flows in solely via the swirl inlet ports. The high eddy generated as a result leads to a more effective mixing of the fuel with air and thereby improved combustion and reduction of soot particles in the exhaust.

When engine speed and load are increasing, the charge intake ports are opened continuously, so that the best possible vortex is created and the required air mass is made available at all times during engine operation. In this way, the exhaust characteristics and the engine performance are optimized.

The position of the flaps in the charge inlet ports is determined by a performance map stored in the CDI control unit. For this, the intake port shutoff motor (M55) is actuated by means of PWM signal. If there is a fault or discontinuity in the supply voltage, the flaps are opened by spring force (when there is no current).
