Diesel Engine Optimization Strategy (DMOS)
- Design of EGR and VGT system control algorithm based on exhaust model for air system optimization of diesel engine


  ● Air system model
        - Estimation of air system status using mass production sensor
        - Consideration of dynamic characteristics on temperature model
        - Calculation of transmission delay according to air flow condition


  ● Feedforward control for EGR valve
        - Calculation of target value based on cylinder pressure and intake air sensor
        - Control of the vane position using VGT model


  ● Emission model
        - Estimation model of NOx emission using cylinder combustion pressure
        - Semi-physical empirical model based on physical laws


  ● Optimization of control variables
        - Performance optimization with steady-state engine calibration
        - Set-point adaptation using the optimized oxygen amount in the transient condition
