Summary:

As the markets require a more environmentally friendly and highfuel consumption vehicle, we have to satisfy bilateral target.Though many new after-treatment techniques like LNT, SCR areinvestigated to meet both strong emission regulations and low fuelconsumption, high cost of these techniques should be solved toadopt widely.This paper describes how to optimize the dual loop EGR as a toolto reduce CO₂ emission of a HSDI diesel engine in the passenger carapplication. Focus is not only on the optimization to obtain themaximum CO₂ reduction but also on how to assess and overcomevarious side effects.As a result of careful optimization, as much as 6% CO₂ reductionwas achieved by introduction of low pressure EGR loop, maintainingthe same boundary conditions as those with high pressure EGR looponly. Not only the dual EGR system but also further improvement wasapplied such as combustion improvement, friction reduction and manyothers to achieve as much as 20% total CO₂ reduction.The dual loop EGR was proven to be an effective solution toreduce CO₂ and therefore it is considered to be one of the coretechnologies in the passenger diesel applications of Hyundai-KiaMotors to meet the future CO₂ regulation
