Abstract
The invention relates to an exhaust system. The exhaust system comprises a sensor used for measuring unburned oxygen in exhaust. The exhaust manifold of the exhaust system basically comprises at least an exhaust manifold which discharge burning gases in a cylinder from a vehicle, at least an oxygen sensor which is arranged in the exhaust manifold, at least a microwave component which is arranged in a preferred location on the surface of the oxygen sensor. The microwave component emits electromagnetic waves to heat the oxygen sensor and burns dust attached to the oxygen sensor.
Description
Technical field
The present invention relates to a kind of vent systems, it comprises the sensor of the unburned amount of oxygen for measuring exhaust.
Background technique
It is necessary that development in car industry in recent years becomes the use of sensor.Especially lambda sensor is installed on enmgine exhaust, and in order to measure the unburned amount of oxygen in exhaust, they make exhaust enter by the hole being arranged on sensor the part that has ceramic fitting, reference gas is provided in ceramic fitting, and by generating the voltage that can be read by the electronic control unit in vehicle, provide the information little or a lot of about air-fuel mixture.
The flue dust that leaves the combustion gas of cylinder adheres on these sensors under certain conditions, and causes the gas access hole plug on sensor.This obstruction can not be carried out sensor and measure and provide accurately false alarm in vehicle.
Owing to not existing in the prior art the flue dust to sticking on sensor to carry out clean mechanism, so attempt to make a change this problem that solves aspect the placement location at sensor and angle.
For implemented with the test of sensor placement location and Angular correlation after the problem that detects, do the design making new advances by analytical method.But, in test, obtain limited result by trial-and-error method.
Japanese documentation No. JP10293113 is application in the prior art, disclose a kind of in order to reduce the fume amount gathering on the surface of the lambda sensor adopting in vehicle the method for developing.On the lambda sensor that is positioned at suction tude, there is lid, in suction tude, have exhaust gas recirculatioon gas and enter air stream.Described lid protection is arranged in the sensor element of sensor end, and has ventilated port above.Utilization has the fin of recessed and curved surface, makes to enter mixture and flows deflection partly, and protecting thus the sensor element of lambda sensor.
European patent document No. EP1541819 be in the prior art another application, disclose for diesel engine from burning clean smoke filter.Described smoke filter comprises for filtering from the smoke filter element of the flue dust of the exhaust of diesel engine with for the heating system of the temperature of at least a portion of the smoke filter that raises.Heating system comprises the microwave oscillator for generating microwave.Smoke filter unit sees through for microwave, and can absorb microwave by flue dust.
Japanese documentation No. JP10123088 is another application in the prior art, and the method for developing is stopped up owing to being adhered to lip-deep flue dust in the inlet opening disclosing in order to prevent lambda sensor lid.On the lambda sensor at pumping tube place that is arranged at diesel engine, add solid electrolyte.This element can be zirconia component etc.Add the lid with introduction hole and the superincumbent rotating member of assembling.Rotating member can rotate with respect to air stream, and utilizes like this air stream to prevent that flue dust from adhering to cover.
Summary of the invention
The object of the present invention is to provide a kind of vent systems, wherein utilize microwave component to clean the flue dust accumulating on the sensor being positioned in gas exhaust manifold.
Brief description of the drawings
The vent systems of developing in order to realize object of the present invention is shown in the drawings, in the accompanying drawings:
Fig. 1 is the schematic side view of vent systems.
Fig. 2 is the stereogram of lambda sensor.
To the each reference character that provides as follows of parts shown in the drawings:
1. vent systems
2. gas exhaust manifold
3. lambda sensor
31. gas inlet orifice
32. mounting holes
4. microwave components
A. flow direction of exhaust gases

Embodiment
Vent systems 1 of the present invention consists essentially of:
-at least one gas exhaust manifold 2, it can discharge from vehicle the combustion gas in cylinder,
-at least one lambda sensor 3, it is configured in gas exhaust manifold 2, and
-at least one microwave components 4, the lip-deep optimum position that it is configured in lambda sensor 3, adds heated oxygen sensor 3 by emitting electromagnetic wave, and makes it possible to the flue dust B burning sticking on lambda sensor 3.
In vent systems 1 of the present invention, the gas burning in cylinder passes through gas exhaust manifold 2 to discharge from vehicle.In the time that the gas of burning advances along gas flow direction A in gas exhaust manifold, gas exhaust manifold 2 utilizes lambda sensor 3 to carry out the unburned amount of oxygen in measurement gas, and lambda sensor 3 is preferably fixed in gas exhaust manifold via mounting hole 32.
In vent systems 1 of the present invention, one or more microwave components 4 are arranged on the lip-deep optimum position of lambda sensor 3.Microwave components 4 utilizes the electromagnetic wave of its transmitting to add heated oxygen sensor 3.Flue dust B on heated lambda sensor 3 is because hot impact is burnt, and therefore lambda sensor cleaned, and removes the flue dust B sticking on lambda sensor.
In vent systems 1 of the present invention, the heat that gas in sensor 3 is sent by microwave components 4 heats, for the flue dust B sticking on sensor 3 is burnt, and therefore solve the inoperable problem of situation lower sensor 3 that does not reach the sufficient temp in sensor 3 in exhaust.
Utilize vent systems 1 of the present invention, eliminated the position of sensor 3 and the difficult design that angle experiences, and the flue dust B by formation having solved in designing gathers.
By clean sensor 3 and by the gas-heated in sensor 3 to specified temp, obtain measurement more efficiently.
In the scope of these basic conceptions, can develop the various embodiments of vent systems 1 of the present invention.The present invention can not be limited to example described herein, and the present invention limits substantially as in the claims.
