    摘要: A diluter for diluting a sample flow of a test gas to allow subsequent measurement of emissions in the test gas. During a calibration mode, a first flow control element receives and controls the dilution flow, a second flow control element receives and measures only the dilution flow, and a third flow control element is closed. Also during calibration, the second flow control element is calibrated to the first flow control element. During a measurement mode, the same dilution flow rate is maintained in the first and second flow control elements, the sample flow and dilution flow are mixed, and the mixed flow flows into both the second flow control element and the third flow control element. Also during measurement, the third flow control element controls sample flow, and the second flow control element delivers a portion of the mixed flow to the instrument.

    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 penetration and removal efficiency calibration unit for a volatile particle remover in a solid particle counting system provides an accurate and efficient approach to calibration. The calibration unit includes an aerosol inlet, a flow meter downstream of the aerosol inlet, and a mixer. The flow meter receives the aerosol flow from the aerosol inlet and provides an output flow to the mixer. The mixer receives the output flow from the flow meter and also has a dilution gas inlet. The mixer provides a mixer output flow for reception by the volatile particle remover or particle counter. A first flow controller controls flow into the dilution gas inlet. The calibration unit also includes a bypass inlet. A second flow controller controls flow into the bypass inlet, and a control loop controls the bypass flow such that the aerosol flow tracks a reference value.

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.
