TECHNIQUES OF ADJUSTING OPACITY ESTIMATES OF THE DIESEL EXHAUST GASES

摘要

The Rules of UNECE No 24 regulated a test method of diesels on the mode of free acceleration. Thus one of procedures provides obtaining opacity estimates of the exhaust gases in very subjective method. Due to the fact that this procedure doesn't include quantitative parameters, it can be understood and implemented by operators differently, that consequently leads to considerable dispersion in results of opacity measurements in practice. Mathematical models of opacity of the exhaust gases depending on rate of movement of a fuel feed pedal is obtained. The technique of a correcting of opacity estimates of the exhaust gases of diesels on the mode of free acceleration with use of static and dynamic models is offered.
