  • System and method for controlling NOx
    Patent number: 9243576
    Abstract: A system and a method for controlling NOx may include predicting NOx generation amount by using a virtual sensor; comparing the NOx prediction amount with a predetermined NOx target amount; and controlling the NOx generation amount so as for the NOx prediction amount to follow the NOx target amount.
    Type: Grant
    Filed: June 21, 2012
    Date of Patent: January 26, 2016
    Assignees: Hyundai Motor Company, SNU R&DB Foundation
    Inventors: Jun Yu, Kihoon Nam, Kyoungchan Han, KyoungDoug Min, Junyong Lee, Wonah Park
  • Method of predicting NOx generation amount
    Patent number: 8849544
    Abstract: A method of predicting NOx generation amount may include calculating NO generation rate by using a combustion pressure of an engine and driving variables of the engine, obtaining NO generation period by using the combustion pressure of the engine, calculating NO generation amount based on the NO generation rate and the NO generation period, and predicting the NOx generation amount by obtaining NO2 generation amount based on a ratio between NO and NO2 according to the NO generation amount and a driving condition of the engine.
