The invention discloses an automobile exhaust temperature sensor comprising a temperature chip, an armored thermocouple cable, and a cable line. The temperature chip is connected with the armored thermocouple cable. The other end of the armored thermocouple cable is connected to the cable line through a terminal insulation buckle. The periphery of the temperature chip is sleeved with a protective cover. The periphery of the armored thermocouple cable is sleeved with a positioning ring. The periphery of the terminal insulation buckle is provided with a tail cover, wherein one end of the tail cover is fixed to the positioning ring, and a sealing plug is plugged between the other end of the tail cover and the cable line. The automobile exhaust temperature sensor of the invention has the advantages of simple and exquisite structure, high monitoring position, convenient use, low production cost and easy large-scale production and use, and has a broad market prospect.
Description
Technical field
The present invention relates to a kind of sensor technology, be specifically related to a kind of vehicle exhaust temperature sensor.
Background technology
Motor vehicle emission pollutant out mainly comprises hydrocarbon, nitrogen oxygenate, carbon monoxide, particulate etc., by the application of the active layer of better catalytic converter, air injection reaction and the technology such as exhaust gas recycling system with cooling device, control and reduce automotive emissions, to reach the standard of below specified value.
Also two kinds of main upgrading schemes are had: a class is by using SCR technology, utilizing urea liquid to process the oxides of nitrogen in tail gas in state four epoch; Also have a class to be by particle trapper or particulate catalyst converter, the particulate for burning generation carries out the EGR Technology processed.At present, domestic Ji Jia large-scale diesel engine factory mostly reduces soot by emission controls by improving combustion, then utilizes SCR technology to reduce discharged nitrous oxides, to meet the regulation to soot and oxides of nitrogen in state IV Abgasgesetz.In two above-mentioned class schemes, all need to detect temperature, and feed back to ECU system, processed to reach emission request standard to discharge by ECU system, need thus to adopt pyrostat to monitor in real time.
But existing automobile exhaust sensor cost is higher or monitoring effect is undesirable, existing use needs can not be adapted to.
Summary of the invention
