摘要:
A method for controlling an automatic transmission in a drive train of a motor vehicle having a transmission controller selecting and shifting gears of the transmission includes determining a new gear by reference to gear shift characteristic curves and generating a gear shift instruction as soon as a working point of the drive train exceeds a gear shift characteristic curve. The transmission controller determines a new gear that is expected to be engaged shortly. If the new gear differs from the current gear, an initial phase of the gear shift is carried out and the gear shift is completed as soon as the gear shift instruction has been generated. The initial phase is carried out as soon as the working point drops below a predefined distance from the gear shift characteristic curve.

Glow plug, particularly for operation in a combustion engine, comprising at least one heating rod (1) and at least one body (2) and at least one annular gap (3) between the heating rod (1) and the body (2) and at least one chamber (4) primarily arranged between the heating rod (1) and the body (2).
摘要:
The invention concerns a glow plug comprising a glow plug body (2), a pressure sensor arranged inside the glow plug body (2), a threaded portion (6) on the outside of the glow plug body (2) and gripping means (12), generally of cylindrical form with a hexagonal section, enabling the body (2) to be gripped and screwed into a corresponding tapping, the gripping means (12) being made from synthetic material.
摘要:
A glow plug (1), includes a pressure sensor (90), suitable for measuring the internal pressure of a motor cylinder in which the plug (1) is housed, a body (10) to be secured to the motor and a finger (20) in which a heater electrode is housed. The sensor (90) is firmly secured to the body (10) by the upper face thereof and rests on the finger (20), so that the pressure exerted on the finger (20) presses the sensor against the body (10).
摘要:
The invention relates to a cylinder pressure sensor comprising a housing for clamping into a cylinder head, which carries a sensor element at a front end. According to the invention, the cylinder pressure sensor has a conical seat at the front end thereof.
摘要:
The invention relates to a glow plug comprises a ceramic glow pencil, a protective sleeve from which the glow pencil protrudes, a housing from which the protective sleeve protrudes. According to the invention, the protective sleeve is fastened to the glow pencil via a holding element which is disposed outside of the housing and is soldered to the glow pencil.
摘要:
A glow plug consists of a tubular body including elements for fixing it into a bore, an intermediate tubular part (30) arranged inside the tubular body, a finger (10′) disposed inside the intermediate tubular part (30) and including a heating electrode and a pressure sensor (14) connected by the face opposite with respect to the finger (10′) to the intermediate tubular part (30), wherein the face of the sensor (14) disposed in front of the finger (10′) is pressed thereto.
摘要:
A glow plug includes a pressure sensor mounted within a tubular member (8) and held in the tubular member (8) by a bearing member. The bearing member is held in the tubular member (8) by plastic deformation (52) of the wall of the tubular member.
摘要:
The preheater plug (1) includes a tubular body inside which a pressure sensor (90) is mounted, the pressure sensor measuring the internal pressure of an engine cylinder wherein the plug (1) is arranged. The pressure sensor is provided with connection lugs extending in a substantially longitudinal manner in relation to the axis of the tubular body. The body (10) has a lateral groove in the inner lateral wall. At least one connection lug is engaged in the groove.
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.
