As the markets require more environmentally friendly and high fuel consumption vehicle, we have to satisfy bilateral target. Though many new after-treatment techniques like LNT, SCR are investigated to meet both strong emission regulations and low fuel consumption, high cost of these techniques should be solved to adopt widely.
This paper describes how to optimize the dual loop EGR as a tool to reduce CO2 emission of a HSDI diesel engine in the passenger car application. Focus is not only on the optimization to obtain the maximum CO2 reduction but also on how to assess and overcome various side effects.
As a result of careful optimization, as much as 6% CO2 reduction was achieved by introduction of low pressure EGR loop, maintaining the same boundary conditions as those with high pressure EGR loop only. Not only the dual EGR system but also further improvement was applied such as combustion improvement, friction reduction and many others to achieve as much as 20% total CO2 reduction. The dual loop EGR was proven to be an effective solution to reduce CO2 and therefore it is considered to be one of the core technologies in the passenger diesel applications of Hyundai-Kia Motors to meet the future CO2 regulation.
