Strategy to Meet Euro IV Emission Norms on Common Rail Sports Utility Vehicle 2007-01-1082
One of the key factors driving the automotive world is emission regulations. Zero emissions, clean engine concept are some buzz words being used extensively in the automotive industry. Stringent emission regulations throughout the world mean that automotive manufacturers have to pay attention to minimizing engine out emissions. Electronic engine management systems allow flexibility in controlling injection parameters & provide a means for optimizing engine performance.
This paper presents work carried out on a 2.49L common rail direct injection diesel engine to achieve Euro IV emission targets. Without after-treatment devices, it is difficult for engine management alone to meet Euro IV and further stringent emissions. To overcome this, two type of after-treatment technologies are adopted by OEM's
Selective Catalyst Reduction
Diesel Particulate Filter
Huge amount of research is being done on the application, cost aspect and availability of component samples for series production. PM - Nox trade-off is always a challenge to researchers for emission optimization on diesel engines. With cooled EGR & oxidation catalyst, the same can be brought under control. Common rail technology allows for multiple injections and immense control over engine parameters. This allows for extreme fine-tuning of combustion parameters.
The present paper deals with application work done on a Common Rail Sports Utility Vehicle to meet Euro IV emission norms.
