The Clean Heavy Duty Diesel Engine of the Future: Strategies for Emission Compliance 2001-28-0045
The internal combustion engines, and the heavy duty truck diesel engines in particular, are facing a severe challenge to cope with the upcoming stringent emission legislation world-wide.
To comply with these low limits, engine internal measures must be complemented with exhaust gas aftertreatment systems with sophisticated electronic control. A reduction of NOx and particulate emission of more than 90% is required.
Various strategies to comply with Euro 4, 5 and US 2007 are discussed, also in view of engine performance, fuel economy and cooling system load.
Recommendations are given for the most suitable approach to comply also in future with emission legislation in Europe and the United States.
