Abstract

The invention discloses a PEMS testing method of a wheeled excavator. The PEMS testing method comprises the steps: installing and debugging a PEMS testing device; starting to carry out earthwork on the wheeled excavator at a point A for a specified time, then moving forward to a point B, and then returning from the point B to the point A to start earthwork again for a specified time; repeating thecycle of A to B for a plurality of times, wherein the specified times for the wheeled excavator to carry out the earthwork at the point A are the same every time, and the wheeled excavator can carryout small-scale operation position adjustment when the wheeled excavator carries out the earthwork at the point A every time until the total power output by an engine of the wheeled excavator reachesa specified test value or the accumulated earthwork working time reaches the test specified time; and carrying out data processing to obtain a PEMS testing result. According to the scheme, the PEMS testing method of the wheeled excavator can fully reflect the emission characteristic of the wheeled excavator under the actual working condition, and has the advantages of being high in repeatability,strong in operability and convenient to use and facilitating comparison of different schemes.

Description

technical field [0001] The invention relates to a PEMS testing method for a wheeled excavator. Background technique [0002] With the increasingly stringent requirements of emission regulations on pollutants emitted by non-road mobile machinery, it is required to carry out PEMS (portable emission test system) testing of the whole vehicle to determine the emission level of the whole vehicle under actual use conditions, in order to further reduce the emission pollution of the whole vehicle . In view of the fact that the current non-road field PEMS testing methods are basically blank. [0003] 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. [0004] The information disclosed in this Background section is only for enhancing the understanding of the general background of the present invention and should not be taken as an acknowledgment or any form of suggestion that the information constitutes...
