Abstract:
.Even though the method described here could not at all be considered as an alternative to the Federal Test Procedures (FTP), specified by the Code of Federal Regulations (CFR 40, Protection of the Environment), a sampling sonde technique (SST) is proposed for particulate matter generation (PMG) analysis. Since this procedure is not accepted by the main regulatory agencies, it can, however, be used to give a reasonable indication of the main characteristics of PMG in Diesel1 engines.An experimental set up is briefly described along with the main results of the analysis. An emphasis is made on some performance conditions that induce a reduction on PMG, when the internal design parameters of the engine can not be changed. The parameters that were changed and subject to experimentation were engine speed and load, and injection timing.
