Definitions
- the invention relates to a device and a method for determining the combustion chamber pressure, in particular of internal combustion engines.
- combustion chamber pressure sensors are e.g. known from DE 10343521, here is a Druckmessglühkerze described for a diesel engine with a plug body for insertion into a cylinder of the diesel engine, a heating element which is arranged in the plug body, and a pressure sensor, which is arranged under a bias voltage between the heating element and the plug body in such a way that the pressure sensor is acted on by the pressure prevailing in the combustion chamber of the cylinder, wherein the heating element is slidably arranged in the axial direction in the plug body and transmits the pressure in the combustion chamber of the cylinder to the pressure sensor.
- combustion chamber pressure sensor shows a glow plug having a cylindrical case whose one end side is located close to a combustion chamber of an engine and which has a threaded portion engaged with the engine; a tubular member held within the housing such that the one end side of the tubular member protrudes from the one end side of the cylindrical housing; a heat generating member located within the tubular member and generating heat in response to supplied current; a metallic center shaft having one end side electrically connected to the heat generating member and the other end side projecting from the other end side of the housing; and a combustion pressure sensor for detecting a combustion pressure of the engine which, when generated, is transmitted via the center shaft as an axial force acting on the tubular member, wherein a portion of the center shaft within the tubular member has a coefficient of thermal expansion of less than or equal to 10.5 * 10 ⁇ -6> / [deg.] C has.
- DE 10 2005 016 463 discloses a glow plug for a self-igniting internal combustion engine, comprising a first, a radiator and a cartridge housing containing module and a pressure measuring module, wherein the pressure measuring module on a radiator side facing away from the first module, wherein at least one force measuring element in the pressure measuring module is integrated, wherein the at least one force measuring element is designed to generate an electrical signal in response to a force, wherein the at least one force measuring element is connected to the radiator such that a force on the at least one force measuring element is transferable via the radiator ,
- a glow plug for a self-igniting internal combustion engine with a radiator and a plug housing wherein the plug housing has at least one force measuring element, wherein the at least one force measuring element is connected to the radiator such that a force on the radiator at least one force measuring element is transferable, wherein the glow plug further comprises at least one connected to the radiator sealing element, wherein the at least one sealing element has at least one element with an elastic property and wherein the at least one sealing element seals the radiator against the plug housing.
- FIG. 5 shows a pressure measuring glow plug subjected to a fault
- the task of a pressure-integrated integrated pressure sensor is to measure the fuel gas pressure in the combustion chamber.
- the heating element 5 is mounted in the middle of the body 6 with two spring diaphragms 1, 2 which can be deformed in the axial direction, with the same spring rigidity, so that the heating element 5 can move axially.
- a reference element 3 such as a magnet is fixed.
- a displacement measuring element 4 such as, for example, an inductive coil attached.
- Another alternative to the displacement measurement is the membrane deformation measurement, as shown in FIG.
- one or more deformation measuring elements 4 such as strain gauges (DMS) or capacitive sensors are applied, which by means of the displacement of the Hetzstabes by the prevailing pressure in the combustion chamber of the internal combustion engine, a signal to the control unit of a motor vehicle via CAN - send bus.
- DMS strain gauges
- FIG. 4 shows a pressure measuring glow plug with membrane deformation measurement acted upon by fuel gas pressure. If a combustion pressure acts on the active surface of the heating element 5 and the combustion chamber side diaphragm, the heating element 5 moves relative to the combustion chamber, the two diaphragms 1, 2 deform in the same direction. The deformation of the diaphragm determined by means of deformation measuring element 4 is used to draw conclusions about the combustion pressure, which is transmitted to the control unit of the vehicle.
- an essential interference signal during the measurement is the externally introduced deformation of the body 6, which likewise can cause a relative movement between the reference 7 and the measuring element 4.
- the reference 7 and measuring element 4 In order to decouple this disturbance, the reference 7 and measuring element 4 must be located in a so-called neutral plane 8, where no relative movement occurs during the deformation.
- the neutral plane 8 is, for example, in the middle of the deformation zone.
- FIG. 6 shows a pressure measuring glow plug with membrane deformation measurement acted upon by external deformation. If the spring diaphragms 1 and 2 have the same spring strength and geometry, the two diaphragms deform to the same extent but in the opposite direction. With the appropriate arrangement and circuit of the measuring elements, this deformation is fully compensated.
