Analysis and Research on the Emission of the CHINA Four-stage Forklift under Real Working Condition
Based on three CHINA Four-stage forklifts,this paper studies their emission characteristics in real working.The results show that all three forklifts meet the CHINA Four-stage emission regulation,and the aver-age specific emission of PN reaches the level of CHINA Six-stage heavy-duty diesel vehicles emission regulation.The average specific emission of PN during the cold start stage is higher than those of effective work event and raw data.If the forklift operates at a lower load during the cold start stage,its average specific emission of CO2 and NOx will be higher than those of effective work event and raw data.The average specific emission of NOx,CO,and CO2 from effective work event are slightly lower or equal to the raw data.The average PN specific emis-sion of the forklifts show an upward trend with the increase of operating load.The moving speed of forklifts,load lifting speed,and load mass are all factors that affect power and emissions.
