    摘要： The invention relates to a pressure measuring device comprising a housing, a rod which is movable in the axial direction in the housing under the effect of combustion chamber pressure and protrudes from the housing, a sensor for measuring combustion chamber pressure acting on the rod, and a diaphragm attached to the housing and through which the rod extends. According to the invention, a second diaphragm said second diaphragm generating a return force when the rod undergoes axial displacement caused by pressure on the rod is disposed between the sensor and the diaphragm.

    摘要： A pressure measuring device includes a housing and a rod which is movable in the axial direction in the housing under the effect of combustion chamber pressure where the rod protrudes from the housing. A sensor measure combustion chamber pressure acting on the rod, and a first diaphragm is attached to the housing through which the rod extends. A second diaphragm is attached to the housing through with the rod extends between the sensor and the first diaphragm. The second diaphragm generates a return force when the rod undergoes axial displacement caused by pressure on the rod.

    摘要： The invention relates to a method for controlling a glow plug to a target value of the surface temperature while the engine is running. An effective voltage is generated by pulse width modulation of a vehicle electrical system voltage. This effective voltage is applied to the glow plug. The electric resistance of the glow plug is measured and compared to a resistance value expected for the target value of the surface temperature. The effective voltage is varied as a function of the deviation of the measured value of the electric resistance from the expected value of the electric resistance. A pressure sensor of the glow plug is used to measure the combustion chamber pressure. The resistance value expected for the target value of the surface temperature is determined as a function of the combustion chamber pressure.
