Problems solved by technology

But it is obviously a serious waste of resources to equip each type of bench system with an exhaust gas analyzer
The engine bench system simulates the real working conditions of the car, the system is huge and complex, and it is not easy to move
The exhaust gas analyzer on the engine bench is also quite heavy, and the movement of the exhaust gas analyzer will seriously affect the normal work of its internal analysis detectors

Abstract

The invention discloses a gas channel automatic switching system of an exhaust gas analyzer. The gas channel automatic switching system of the exhaust gas analyzer comprises an exhaust gas analyzer, engine pedestals and gas channels connecting the exhaust gas analyzer with the engine pedestals, wherein multiple engine pedestals are connected to the exhaust gas analyzer through multiple gas channels; and each gas channel is provided with a channel switch for controlling the gas in the gas channel to pass through or not. The gas channel automatic switching system of the exhaust gas analyzer, disclosed by the invention, realizes flexible matching of the exhaust gas analyzer and pedestal systems of multiple types, realizes integrated utilization of resources of the exhaust gas analyzer and the pedestal system, guarantees normal work of equipment and guarantees to save cost.

Description

technical field [0001] The invention relates to the field of gas analysis, in particular to an automatic gas channel switching system for an exhaust gas analyzer. Background technique [0002] The engine bench exhaust gas analyzer integrates a heated total hydrocarbon analysis detector, an oxygen analysis detector, and a heated nitrogen oxide analysis detector, which can simultaneously realize the analysis and detection of engine exhaust pollution components. The degree of centralization is high, so the price is high . There are three types of engine benches: gasoline engine benches, diesel engine benches and motorcycle benches. Modern large-scale automobile exhaust purifier manufacturers are based on the development of multi-type and high-tech exhaust purifiers, and generally invest a large scientific research budget to equip these three types of bench systems. But it is obviously a serious waste of resources to equip each type of bench system with an exhaust gas analyzer...
