Übersetzung für "Rail pressure sensor" in Deutsch

A functional rail pressure sensor is also imperative for this method.

The pressure level pCR in the rail is recorded by the rail pressure sensor.

A functional rail pressure sensor is imperative for the method presented.

A check is made at S 1 whether a defective rail pressure sensor has been detected.

Common rail systems of this type have a rail pressure sensor which is an integral component of the common rail injection system.

The pressure level of the high-pressure accumulator 7 is determined via a rail pressure sensor 10 .

The pressure level of the high pressure accumulator 6 is measured by a rail pressure sensor 9 .

The open end of blind hole 2 is closed with a rail pressure sensor 3 .

For pressure regulation, a rail pressure sensor, not shown, is needed and is typically disposed on the common rail 25 .

Rail pressure sensor 3 is surrounded by a protective sleeve 4, which has the shape of a hollow cylinder.

Increased fuel flow is achieved through a returnless fuel system, twin variable flow fuel pumps and a new closed loop fuel rail design with pressure sensor.

The use of bioethanol also requires new valve coatings and hardened valve seat material for additional lubrication, a new closed loop fuel rail design with pressure sensor for higher fuel flow rates and new spark plugs with a wider heat range for slower combustion.

Via high-pressure lines 12, the compressed fuel reaches at least one rail 6, which inter alia is equipped with at least one pressure control valve 13 and a rail pressure sensor 7 .

The following are shown over the period: rail pressure pCR, the process variable SD for identification of a defective rail pressure sensor, a process variable ST for identification of the suction throttle flow, an engine start signal START, a process variable PLV for identification of the state of the pressure limiting valve, a process variable D 1 for the yellow alarm, a process variable D 2 for the red alarm, a process variable engine idle EI for identification of a combustion engine in a steady-state and an RS signal as reset signal.

For this reason, the point at which the valve opens is assumed to be the same time as when both a defective rail pressure sensor was detected, here time t 1, and the starting phase of the combustion engine ended.

The following are shown over the period: the rail pressure pCR, a counter C, the process variable SD for identification of a defective rail pressure sensor, a process variable ST for identification of the suction throttle flow, an engine START signal, a process variable PLV for identification of the state of the pressure limiting valve, a process variable D 1 for the yellow alarm, a process variable D 2 for the red alarm, a process variable engine idle for identification of a combustion engine in a steady-state and an RS signal as reset signal.

The exemplary illustrations are based on the problem of detecting an open pressure limiting valve even in the event of the failure of the rail pressure sensor in a generic common rail system.

At time t 6, the rail pressure sensor is replaced, the displayed sensor defect disappears, i.e. the SD signal is reset to SD=0.

The alarms would also be reset even if the defective rail pressure sensor were not replaced at this point.

Since both conditions are now met, i.e. the rail pressure sensor is defective and the starting phase has ended, the pressure limiting valve is set as open.

The present disclosure relates to exemplary methods for monitoring a passive pressure limiting valve via which fuel is discharged from the rail of a common rail system into the fuel tank, in which method, upon the detection of a defective rail pressure sensor, a switch is made from a rail pressure regulation mode into an emergency mode, wherein in the emergency mode, the rail pressure is gradually increased until the pressure limiting valve responds.
