Abstract
With newer emission norms getting introduced, OEMs are struggling hard to achieve those norms. This is because selection of appropriate technology for stringent emission norms has to be ensured in order to control higher costs and also to control adverse affect on fuel consumption.
This paper briefs about the real life experience in developing Euro 4 emissions on a Sports Utility Vehicle (SUV) fitted with 2.2 liter CRDe engine. The base vehicle used is BSIII emission complaint. Efforts were made to optimize the overall emission system without use of any particle trapping device in the exhaust and with conventional air intake system.
Steady and transient operating speeds of the driving cycle were optimized through common rail technology. Maximum benefits from common rail technology were captured which also were assisted by efficient Exhaust Gas Recirculation (EGR) cooling and intercooling. At the end different after treatment options were evaluated to arrive at optimum use of catalyst.
Thus with this approach, low cost solution for meeting Euro 4 emissions is demonstrated.
