摘要： A real-time particulate matter measuring system includes a hot diluter for receiving and diluting aerosol. An evaporation unit receives the diluted aerosol. A cold diluter receives and dilutes the output flow from the evaporation unit. A condensation particle counter receives the diluted output flow and measures the particle number concentration. An integrated device also receives the diluted output flow. The integrated device measures at least one of particle diameter concentration and particle surface area. The integrated device also measures mass concentration.

摘要： A solid particle counting system for measuring solid particle number concentrations from engine or vehicle exhausts in real-time includes a flow splitter having an inlet, a sample outlet, and a by-pass outlet arranged such that a main flow enters the inlet and changes direction to exit the by-pass outlet. A sample flow from the main flow exits the sample outlet. The flow splitter further includes a guiding element arranged such that particles at a sampling location upstream of the main flow direction change are guided to the sample outlet.

摘要： A solid particle counting system for measuring solid particle number concentrations from engine or vehicle exhausts in real-time includes a diluter arrangement, a particle counter, and a flow splitter. The diluter arrangement mixes the dilution gas with flowing sample gases. The flow splitter receives the output flow from the diluter arrangement, provides a portion of this flow to the particle counter, and provides a by-pass flow that is received by a vacuum pump. A second flow route to the particle counter includes a valve arranged such that opening the valve during the starting of the vacuum pump reduces a pressure pulse at the particle counter caused by the starting of the vacuum pump, thereby avoiding work fluid backflow from the particle counter prior to the vacuum pump stabilizing.

摘要： A particle generating system includes an aerosol generator, an ejector diluter, and an aerosol diluter. The ejector diluter receives the generated aerosol and dilutes the aerosol to an expected raw concentration. The aerosol diluter further dilutes the aerosol to a concentration in the range of 0% to 100% of the expected raw concentration. The aerosol diluter includes a mini cyclone for diluting the aerosol. The particle generating system may be configured to provide variable concentrations of monodisperse or polydisperse aerosols for instrument calibration. The system may provide constant concentrations in the range of 0% to 100% of the raw concentration. The mini cyclone makes the system compact, and the system may be portable.

摘要： A partial flow sampling system includes a system inlet for receiving an exhaust sample flow from a sample inlet probe and transfer line. The system further includes a dilution air control system for controlling a dilution air flow rate, and a mixer. The mixer receives and mixes the exhaust sample flow and the dilution air flow to produce a mixture flow. A total flow control system controls the mixture flow rate. An orifice flow meter installed at the system inlet measures the exhaust sample flow rate in. real-time. This provides accurate sample flow measurements over a wide range of dilution ratios and sample ratios.
