Test Correlation

Diesel engine particulate certification, heretofore limited to on-highway truck engines, will be expanded in scope beginning in 1996. “Mini-dilution” tunnels have been the European and Japanese systems of choice for dilute particulate emissions certification for non-U.S. truck diesel engines. However, repeatability, steady-state test correlation versus full dilution systems, portability, sampling time, size, and system cost have precluded universal industry and regulatory acceptance of existing “mini-system” designs. To address corporate particulate measurement needs, the author developed a device known internally as the “Micro-Dilution Particulate Measurement System,” which meets the following objectives: (1) correlation with full dilution systems within ISO 8178 equivalency standards, (2) short sampling time, (3) reduced setup effort, and (4) excellent portability. Since the system is a true fractional sampler, it is insensitive to engine size, requiring only a simple stack probe change to provide accurate, representative steady-state diesel stack sampling on any size diesel engine.

Impedance Aggregometry

SummaryThe aggregation/adhesion response to platelet activating factor (PAF) was studied in diluted whole blood by impedance aggregometry. The extent of aggregation varied directly with the interval between blood sampling and aggregation measurement over the first 30 minutes from sampling, then remained stable for the next 60 minutes of observation. This is an effect opposite to that described for aggregation to PAF in platelet rich plasma which, however, cannot be studied soon after sampling. Time dependence of aggregation is important and comparative measurements should be made during the period of stable aggregability.
