Embodiment Construction

[0027] The following figures describe some possible embodiments of the present application.

[0028] The present application is generally oriented to the wireless monitoring technology of engine exhaust gas. This application is applicable to the engines of various equipment or vehicles, especially to the engines of medium and large equipment or vehicles, such as medium and large passenger cars, municipal vehicles, engineering vehicles, etc., especially medium and large vehicles fueled by diesel and / or natural gas engine.

[0029] The present application proposes a wireless engine exhaust monitoring device that cooperates with an engine system, especially an engine exhaust after-treatment system. Such as figure 2 As shown, the engine system includes an engine (such as a diesel and / or natural gas engine) 1 and an exhaust gas after-treatment system for treating the exhaust gas of the engine 1 . The exhaust gas after-treatment system includes various exhaust gas treatment comp...

Abstract

The invention provides an integrated tail gas wireless monitoring device. The device comprises a tail gas sensor and a wireless communication module; the tail gas sensor is used for detecting information of tail gas to be emitted to the atmosphere by an engine; the wireless communication module is integrated in a certain controller of an engine system; and the tail gas information is collected inthe controller, the wireless communication module is connected with a CPU of the controller in a manner that data can be transmitted, so that the wireless communication module can obtain the tail gasinformation in the controller and transmit the tail gas information wirelessly.

Description

technical field [0001] The present application relates to a technology for remote wireless monitoring of engine, especially diesel and / or natural gas engine exhaust emission quality. Background technique [0002] Vehicle engine exhaust contains many harmful components. In order to reduce harmful components in exhaust gas, various exhaust gas after-treatment systems have been proposed. However, even after being treated by the exhaust after-treatment system, the exhaust emissions may still not meet the standards. This is because some exhaust treatment components in the exhaust aftertreatment system degrade over time. When the performance of the exhaust gas treatment element decreases to a certain extent, it needs to be replaced or regenerated. However, sometimes it is difficult to monitor the condition of the exhaust gas treatment components, so they are not replaced or regenerated in time. In this way, the exhaust gas after-treatment system may not work properly, so the co...
