Übersetzung für "Cylinder deactivation" in Deutsch

In this way, the internal combustion engine can be operated during cylinder deactivation in a particularly advantageous and efficient manner.

Such a cylinder deactivation can result in an asymmetrical load on the crankshaft of the piston engine.

Thanks to standard cylinder deactivation, the engine is actually even more efficient.

The new 1.5 TSI has the special feature of cylinder deactivation.

The system can in addition allow for cylinder deactivation.

Cylinder deactivation is achieved by keeping the intake and exhaust valves closed for a particular cylinder.

This cylinder deactivation is used particularly frequently when driving constantly at mid-range speed and with a low engine load.

Methods of cylinder deactivation, referred to as ‘skip firing’, are known from the state of the art.

Methods of cylinder deactivation, referred to as “skip firing”, are known from the state of the art.

The baseline pattern for cylinder deactivation can be matched to the currently prevailing power requirement of the internal combustion engine.

The same applies to engines with four to six cylinders, which have a performance-dependent cylinder deactivation.

It is the principal object of the present invention to provide a motor vehicle valve train adjustment device with a particularly advantageous cylinder deactivation system.

In this way, in particular the cam elements of the exhaust camshaft can be switched in a particularly advantageous manner for cylinder deactivation.

This system has now been extended by adding additional functions, which support state-of-the-art combustion processes and allow cylinder deactivation without a loss of comfort.

The robust industrial motor with electronic speed control and a compressor with cylinder deactivation reduce the fuel consumption.

On completing the Essencyele project, Valeo will market an electric motor with integrated electronics (the “i-Motor”) and four new components for combustion engines: an engine control unit (ECU), an exhaust gas recirculation (EGR) system, an electrified turbocharger turbine wastegate actuator (turbo e-actuator) and an electrified cylinder deactivation system (e-DoD).

Even if plural cylinder deactivation patterns are predetermined and those patterns are interchanged, that has the disadvantage that when switching over the patterns plural cylinders make the transition from a fired to an unfired condition and vice-versa.

Thus, in the transition from one cylinder deactivation pattern to another pattern, the situation can arise where plural cylinders which are in succession in their firing sequence are deactivated, that is to say, there is a longer sequence without ignition events.

In the proposed method, the cylinder deactivation pattern (referred to as the skip firing order) is firstly derived from the ignition sequence (referred to as the firing order) of the engine in question.

For example, for diagnostic purposes, it may be an aspect of interest for a particular cylinder to be excluded from cylinder deactivation.

In addition, it is proposed that the motor vehicle valve train adjustment device has at least one exhaust camshaft that comprises at least two cam elements arranged in an axially displaceable manner, wherein at least one cam element of the at least two cam elements has a cam track with valve lift and a cam track with zero lift for cylinder deactivation.

In this way, the at least one other cam element that is associated with a cylinder that is still operative during cylinder deactivation in the partial cylinder deactivating engine operating state in a particularly advantageous manner.

The second cam tracks 32, 33, 34, 35 of the second cam element 17 and the third cam element 18 have a zero lift for cylinder deactivation.

It is principally also conceivable that only the cam elements 17, 18 of the exhaust camshaft 11, which comprise the cam tracks 32, 33, 34, 35 with zero lift are designed to be switchable and are switched for cylinder deactivation.

The internal implementation of the VLC and ELC process is based on the idea according to the invention of using the cylinders deactivated in the cylinder deactivation for the process of expansion or also of compression of the fresh air (volumetric load control).

To save fuel outside of a full load range of a multi-cylinder piston engine, it is known to implement a cylinder deactivation for at least one cylinder of the piston engine.

To be able to provide a certain target load at the same rotational speed when the cylinder deactivation is activated, the remaining and still active cylinders have to provide a correspondingly higher load.

Hereby, for a multitude of operating points, a more uniform load for the crankshaft can be implemented in comparison to an operation with cylinder deactivation.
