Gas analyzer gas distribution device, gas analyzer measuring device, internal combustion engine and gas analyzer

Abstract

The utility model discloses a gas distribution device of a gas analyzer, a measuring device of the gas analyzer, an internal combustion engine and the gas analyzer, and relates to the technical field of analyzers, the gas distribution device of the gas analyzer comprises a measuring port, a plurality of electromagnetic valves and a logic device, one end of the measuring port is connected with a first sampling port of the gas analyzer, and the other end is connected with the exhaust pipe which is used for collecting a gas mixture discharged by a plurality of engine cylinders; for each electromagnetic valve, one end of the electromagnetic valve is connected with a second sampling port of the gas analyzer, and the other end of the electromagnetic valve is connected with a target engine cylinder corresponding to the electromagnetic valve; the logic device is used for controlling opening and closing of the electromagnetic valve. Through the arrangement of the measuring port and the electromagnetic valve, gas can be accurately sampled from different cylinders of the engine, and the analysis accuracy is ensured. Through automation and accurate control, errors caused by manual operation are reduced, and the detection efficiency is improved. And the measurement requirements of multi-cylinder mixed gas of internal combustion engines of any type can be met.
