Translation of "Turbo lag" in German

This avoids the so-called turbo lag in response to positive load variation.

With the following method step a turbo lag can be eliminated:

This slow response characteristic is also known colloquially as turbo lag.

In this way, the often-cited turbo lag can be avoided.

By switching to special operation, the so-called turbo lag in response to a sudden positive load variation is avoided.

And as a result, this improves regulated response at low revolutions and reduces turbo lag.

Opposing the aforementioned advantages is the known problem of the retarded response time of exhaust-driven turbocharged engines ("turbo lag").

It thus follows that there is a further delay when accelerating in addition to the already mentioned delayed response of the turbocharger, i.e. the turbo lag, because the desirable ram pressure build up for the rapid running up the turbine only appears after the waste gate is closed.

A turbo-lag described above, for example, is in this manner effectively prevented in the starting power of a vehicle with internal combustion engine loaded with exhaust gas.

The driver feels this as an undesirably slow build up of the output torque of the vehicle usually designated as “turbo-lag”.

The second generation, starting production from late 1994, was fitted with a Garrett T25 turbocharger, a smaller unit which reduced turbo lag and increased usability in everyday driving situations.

Charging of the internal combustion engine should occur quickly. This is possible only when the turbocharger quickly starts up so as to eliminate the undesired turbo lag.

At the start of the torque demand, the charge-air pressure which is delivered by the exhaust-gas turbocharger 2 and which is measured as an inlet pressure 27 in this example by the second pressure sensor 19, is still very low (“turbo lag”).

For example, piston engines such as diesel engines having an exhaust-gas turbocharger 2 have, for example, an operating state during acceleration which is referred to as “turbo lag”.

To bridge this “turbo lag”, solutions have been proposed in which compressed air, for example from a tank 13, which is fed by an air compressor 14, is introduced in a controlled fashion into the intake line 9 ? of the internal combustion engine 1 in order, in the event of an increased intake air demand of the internal combustion engine 1, to cover the demand.

In order to reduce what is known as the “turbo lag”, in which the internal combustion engine reacts to the accelerator with a speed increase only after a certain delay time, compressed air, for example from a compressed air store 18, which is fed by a compressor 17 driven (double strokes) by the internal combustion engine 12, is introduced through a compressed air line 19 in a controlled manner into the intake line 20 of the internal combustion engine 12, in order to cover the intake air demand in the event of an increased intake air demand of the internal combustion engine 12 .

In order to now be able to adapt the operating range of the exhaust-gas turbocharger to changing operating ranges of the internal combustion engine, and thus ensure a desired response behavior as far as possible without perceptible delays (turbo lag), exhaust-gas turbochargers are equipped with so-called variable turbine geometries and with bypass ducts that can be opened by means of valve flaps.

In particular, so-called turbo lag, i.e., an absent or low charge pressure, and consequently low power of this type of engine 1 in low speed ranges, is thus preventable, or this problem may be at least considerably reduced, and, for example, driving behavior and fuel consumption of a vehicle driven by this engine 1 may thus be optimized.

To bridge this “turbo lag”, proposals for a solution have been made in which compressed air is introduced, for example from a compressed air reservoir 6 fed by an air compressor 7, into the intake line 13 of the internal combustion engine 1 in a controlled manner, in order, when the internal combustion engine 1 has an increased intake air demand, to cover this.
