The Effects of Testing Procedure and Limitations of Pollutant Emissions on the Design Development of Diesel Engines 785060
Automotive emission limitations and the means by which
compliance with these limitations are verified directly influence
engine design. The paper examines the optimization of these
limitations and the verification procedures for Diesel engine
operation.
Emission testing is examined with concentration on various
points: comparison of different national procedures, the effect of
the total number of tests, the standardization of procedures for
different vehicle types, and the suitability of steady-state tests
for unsteady operation. Establishment of effective pollution limits
deals with other questions: which emissions should be controlled,
what criteria determine limiting values, do different criteria
apply to different vehicle classes? Finally, a representative
sampling of vehicles with Diesel engines are evaluated according to
selected emission limits and a defined testing procedure; the
effect of different Diesel engine designs on emissions are shown
and various improvements are suggested, where necessary, to permit
compliance with the emission regulations. Consequently, the
regulations and testing procedure effectively establish design
goals for engine development.
