Description of drawings
One embodiment of the present of invention are expressed to reach in the following description in the accompanying drawings and are described.
Fig. 1 represents to be arranged on a device that is used to detect chamber pressure on the cylinder of internal-combustion engine, and it has one by the red-hot head pressure detecting part that plug receives of igniting.
Embodiment
Fig. 1 represents the device that is used to detect the chamber pressure of internal-combustion engine according to one of the present invention.This device comprises one red-hot the plug 1 of igniting, and this red-hot head is ignited to fill in and is set on the cylinder head of internal-combustion engine 2.This red-hot head is ignited to fill in and is had for example columniform, as to cover an inner room 6 a metal valve jacket 14, this valve jacket can be single type or for be easy to assemble also can be advantageously for multi-part type, as shown in this embodiment, have for example one first housing parts 14c and one second housing parts 14d and this valve jacket and extend in red-hot head and ignite on the direction 8 of packing into of plug 1.In addition, this red-hot head plug 1 of igniting has for example red-hot 12 of pottery, and this red-hot head is welded in the support tube 13, and this support tube is soldered or be pressed among the housing parts 14c of valve jacket 14, so that guarantee the ignite sealing of plug of red-hot head thus.The second housing parts 14d of valve jacket 14 has for example fixed mechanism 14b of external thread form on its circumference.This red-hot head plug 1 of igniting is screwed on the direction 8 of packing in the mounting hole 5 of cylinder head of internal-combustion engine 2 in known manner, and plug 1 is provided with red-hot 12 section 11 towards the firing chamber 3 so that red-hot head is ignited.Valve jacket 14 has the ring surface of a taper on it is inserted into the end face 14a of end of mounting hole 5, be used for by touching the conical sealing seat 9 in cylinder head.The required preload of sealing that is used for conical sealing seat produces by fixed mechanism 14b when mounted.
In addition, red-hot head ignite plug 1 within it portion have one and be used for being enclosed within insulating element 17 on red-hot 12 and the graphite member 15 with the graphite member 15 of red-hot 12 contacting and one on the positive contact, this insulating element insulate red-hot 12 positive contact and graphite member 15 and the red-hot head earthy valve jacket 14 that is in filled in of igniting mutually.Graphite member 15 is connected lead 16 with one and is connected, and this connection lead passes insulating element 17.Realize by support column 13 and valve jacket 14 to the connection of motor ground (Motormasse) red-hot 12 negative contact.
In the mounting point, red-hot head ignite the section that stands chamber pressure 11 of plug 1 comprise red-hot 12, support tube 13 and valve jacket 14 end face 14a not by touching the zone on conical sealing seat 9.Always being applied to the ignite pressure of combustion chamber side section 11 of plug of red-hot head by the firing chamber affacts red-hot head always and ignites on the fixed position of plug and affact on the fixed mechanism 14b thus always.A piezoelectric element is housed in this power path, for example a quartz transducer element is as pressure detecting element 20.But also can use piezoelectric constant or other suitable element.That pressure detecting element 20 is configured to plate-like and have one first ring surface and one and deviate from second ring surface of first ring surface and one and be used to pass the endoporus that connects lead 16.Pressure detecting element 20 usefulness first ring surface is bearing on direction 8 vertically extending first supporting surfaces 21 of packing into relatively of valve jacket.This first supporting surface 21 for example is configured on the first inner process 14e of valve jacket 14, and this inner process is extend in the inner room 6 by the inwall of valve jacket 14 diametrically.In addition, one of pressure detecting element 20 usefulness deviate from first second by touching on direction 8 vertically extending second supporting surfaces 22 of packing into relatively of valve jacket 14.This second supporting surface 22 is built on second inner process 26, and this inner process for example constitutes by a sleeve 18 with the inwall welding of valve jacket 14.The also available direction of packing into relatively of first and second supporting surface is different from the angle of zero degree and arranges.Pressure detecting element 20 usefulness first face of annular is placed on first supporting surface 21.Then sleeve 18 can be inserted in this wise in the inner room 6 of valve jacket 14, make second supporting surface 22 that is configured on the sleeve reach by touching on second of pressure detecting element 20.The excircle of sleeve will be permanently connected by being welded to connect 23 with the inwall of valve jacket 14.On the direction 8 of packing into, pressure detecting element 20 is set between the section 11 and fixed mechanism 14b of combustion chamber side.
Only transmit on the position of the first inner process 14e by the force flux of section 11 by valve jacket 14 towards fixed mechanism 14b.Flexible connection lead 16 does not transmit power.Force flux by the area part that is provided with inner process of valve jacket 14 be directly delivered on the pressure detecting element 20 and partly be delivered to valve jacket 14 on the wall section 24 of pressure detecting element, thus force flux with constant ratio pressure detecting element 20 with around distribution between the wall section 24 of this pressure detecting element.This ratio only cross section and the rigidity with valve jacket and pressure detecting element is relevant, and the two keeps constant in length of life.
Advantageously, sleeve 18 welds in this wise with valve jacket 14, makes pressure detecting element 20 originally not be subjected to preload.When being screwed into cylinder head, red-hot the plug of igniting to carry out the preload of pressure detecting element and the jumping-up of consequent valve jacket 14 then.In order to reduce the pressure stress of pressure detecting element, also a little air clearance can be set between pressure detecting element 20 and sleeve 18 at first, this air clearance for example can be realized in this wise, promptly activates the piezoelectric effect that ground (aktorisch) utilizes pressure detecting element when welded sleeve 18.Be closed this air clearance when igniting plug being screwed into red-hot head.Can reach thus: bear that higher to be screwed into that load maybe can use be not sufficiently withstand voltage pressure detecting element in other cases.
Behind welded sleeve 18, carry out a pressure detecting element 20 and a circuit part 19 contacting, for example undertaken by welding process.Pressure detecting element 20 hole 27 within it is provided with electric wiring 25, and they are with connecting the endoporus that lead 16 passes sleeve 18.Pressure detecting element 20 is connected with circuit part 19 in the inner room 6 that is arranged on valve jacket 14 by electric wiring 25.Circuit part 19 is used to receive evaluation circuit (electric charge-or electrometer amplifier) and is used for that the parts of EMV wiring-they are schematically shown in the drawings-and for example can be bonded in unshowned plastic components here.The second housing parts 14d is put and is welded with the first housing parts 14c after having welded sleeve 18 and having produced contacting.The outside connection that red-hot head current connects lead 16 and circuit part 19 realizes that by an electric terminal 7 this electric terminal is connected lead 16 connections and is configured on the side that deviates from the firing chamber of red-hot the plug 1 of igniting with circuit part 19 and with red-hot head current.
By first supporting surface 21 by pressure detecting element 20 affact on second inner process 26 force flux pressure detecting element 20 on the ring surface of first supporting surface 21, produced a pressure, in pressure detecting element 20, produce carrier freely thus.Ignite on the circuit part 19 in the plug 1 for signal processing for example can be provided with an amplification circuit (electric charge-or electrometer amplifier) being arranged on red-hot head, it by the outflow charge generation that in pressure detecting element, forms go out a voltage and by calibrate (Abgleich) also can be used as sensor output signal provide a definite characteristic curve (for example 0.5 and 4.5V between).The size of this voltage with act on pressure correlation on the pressure detecting element, this pressure is relevant with applied pressure under the constant situation of the cross-section area of piezoelectric element.
A feature of the signal processing by electric charge or electrometer amplifier is that the electric charge that piezoelectricity produces flows out along with the time and makes measurement signal close on zero thus.This means that simultaneously change-this pressure change that acts on the pressure on the quartz transducer element is slower than significantly because the change-will can not produce the measurement error of offset form of the pressure distribution in the firing chamber.Its sensitivity of this characteristic with quartz-be differently have nothing to do-will cause with preload force with piezoelectric constant: as long as there is a minimum pre-load power, lifting and falling on the quartz transducer element (Aufsetzen) can not appear in this minimum pre-load card of trying hard to keep, the slow change of preload force does not just produce measurement error, and the slow variation of described preload force for example is by the temperature variation of cylinder head or is screwed into formation by on being installed to cylinder head the time.This lifts and falls the inefficacy in advance that may cause measurement error and quartz transducer element.Therefore only need for correct pressure measurement: have the reaching an of univocality between the pressure in the firing chamber and the power that acts on the quartz transducer element in the constant relation of length of life.Another quartzy advantage is the high-stability of its compression resistance load.
