Abstract

The invention discloses a PEMS testing method for an air compressor. The PEMS testing method comprises the following steps of mounting PEMS testing equipment; testing the operation cycle working condition of the air compressor; testing the operation cycle working condition of the air compressor comprises the following steps of starting an engine to set the idling speed of the air compressor, and switching to a working mode; opening a compressed gas outlet, so that the pressure of the compressed gas outlet reaches the maximum value set by the air compressor, operating a first time period; adjusting the pressure of the compressed gas outlet to 90% of the maximum pressure value, and operating a second time period; adjusting the pressure of the compressed gas outlet to 80% of the maximum pressure value, and operating a third time period; adjusting the pressure of the compressed gas outlet to 70% of the maximum pressure value, and operating a fourth time period; adjusting the pressure of the compressed gas outlet to 60% of the maximum pressure value, and operating a fifth time period; idling for a sixth time period, and completing one working cycle; and repeating the operation cycle working condition testing steps of the air compressor until the stopping condition is reached.

Description

technical field [0001] The invention relates to the field of engines, in particular to an air compressor PEMS test method. Background technique [0002] An air compressor is a machine used to compress air to increase air pressure. With the increasingly stringent requirements of emission regulations on pollutants emitted by non-road mobile machinery, it is required to conduct PEMS (short for portable emission test system) test of the whole vehicle to determine the emission level of the whole vehicle under actual use conditions, in order to further reduce the emission of the whole vehicle Discharge pollution. In view of the fact that the current non-road field PEMS testing methods are basically blank. Currently, PEMS testing in the non-road field is in the initial stage of research, and there is a lack of a standard testing method. This scheme proposes a PEMS test method for air compressors, which can fully reflect the emission characteristics of air compressors under actua...
