Engine Control Using Intake, Combustion and Inertia Models 2000-01-2806
The combination of physical models of an advanced engine control system was proposed to obtain sophisticated combustion control in ultra-lean combustion engines, including homogeneous compression-ignition and activated radical combustion. Physical models of intake, combustion (including engine thermodynamics), and inertia were incorporated, in which the effects of residual gas from prior cycles on intake air mass and combustion were taken into consideration. Control of the in-cylinder air/fuel ratio, exhaust temperature and engine speed during start and post-start phases was investigated using simulations.
