Abstract
Emission testing of light duty diesel engines performed by means of a number of testins facilities that are connected to a central control system is described. Two kind of benches are available; steady state and inertial.
The first is mainly used to obtain emissions and fuel consumption maps in a fully automatic fashion. The data are then processed to predict the fuel consumption and emissions of a given driving cycle.
The other kind of bench performs a comprehensive car simulation and therefore permits the execution of dynamic cycles such as the 1975 Federal Test Procedure (FTP). Both the diluted gas sampling and the driving actuation are automatically done by computer.
Experimental results obtained on a IVECO 4-cyl turbocharsed IDI diesel engine for light duty operation are presented.
