Drivability Improvements on Electronic Diesel Engines

The new 2005 Brazilian emissions legislation for diesel vehicles, based on EURO III, requires more complex emission control systems, like electronic engine management systems. The introduction of an electronic engine management system allows improvement in important aspects to the customer perception, such as drivability and vehicle noise levels. The objective of this paper is to compare the gains in terms of drivability of vehicles with electronic engine management system and conventional mechanical system, based on acceleration curves, driving behavior and vehicle speed
