Übersetzung für "Vacuum manifold" in Deutsch

Therefore, this method presupposes a high intake manifold vacuum.

This valve position obtains whenever the intake manifold vacuum is very low or virtually no intake manifold vacuum exists.

This valve position is in effect whenever the intake manifold vacuum is very low or when virtually no intake manifold vacuum prevails.

In this position the greatest possible throughput of blow-by gases can be achieved even at a low intake manifold vacuum.

In this position the greatest possible throughput of blow-by gases can be achieved even under low intake manifold vacuum.

In another development of the invention, the intake manifold vacuum is measured.

The Variomatic also permitted increased engine braking by operating a switch on the dashboard which reversed the action of the vacuum on the pulley's diaphragm, seeking a lower ratio with increased manifold vacuum.

Article 3(10) defines defeat device as any element of design which senses temperature, vehicle speed, engine speed (RPM), transmission gear, manifold vacuum or any other parameter for the purpose of activating, modulating, delaying or deactivating the operation of any part of the emission control system, that reduces the effectiveness of the emission control system under conditions which may reasonably be expected to be encountered in normal vehicle operation and use.

But as soon as the pressure in the crankcase increases in this illustrated position, or the intake manifold vacuum decreases, the diaphragm will again lift off from the valve seat 21 of the intermediate valve 18 and thus also first the smaller opening will be opened and, as the intake manifold vacuum continues to decrease (for example the vacuum in the intake manifold of the internal combustion engine decreases due to the opening of the main throttle valve), eventually the larger opening, i.e., the valve between the valve seat 17 and the valve plate 19, will also be opened.

In addition, in internal combustion engines having GDI or electronic throttle control (e-gas), the throttle valve may be controlled independently of the pedal sensor position, so that the manifold vacuum pressure is restricted in terms of its availability for servo functions.

Stratified operation accompanied by direct injection may be a comparable operating state, where, even at a low load, the throttle valve is fully open, so that, as a result, no manifold vacuum pressure may be available.

The changes in the operating state having elevated intake-manifold vacuum pressure may be made furthermore by intervening in the power efficiency specifications or in the operating state specifications of the engine management.

Another option is to attach a vacuum cell, which can be switched by the intake manifold vacuum, for example.

At t 2, fuel-tank venting valve 20 is triggered 204 to open, so that because of the existing intake manifold vacuum, during the actual opening of fuel-tank venting valve 20 a pressure drop 206 is established in the tank system.

The method according to the present invention may also be used with systems having only a slight intake manifold vacuum, e.g., VVT systems.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The system 1 is installed in the vehicle being tested where it will measure automatically, without requiring operator attendance, the driveability-relevant measurement variables 2, 3 of operational states of engine A and/or vehicle B, such as engine speed, position of throttle or accelerator pedal, vehicle speed, longitudinal vehicle acceleration, intake manifold vacuum, coolant temperature, ignition timing, injection volume, lambda value, exhaust gas recirculation rate, exhaust gas temperature.
