Transient Control of Combustion Phasing and Lambda in a 6-Cylinder Port-Injected Natural-gas Engine
Författare
Summary, in English
This paper presents different control strategies to maximize the reliability for maintaining efficiency and emissions levels under transient conditions. Different
controllers are developed and tested successfully on a heavy duty 6-cylinder port injected natural gas engine. Model Predictive Control (MPC) was used to control lambda which was modeled using System Identification. Furthermore, a Proportional Integral (PI) regulator combined with a feedforward map for obtaining Maximum Brake Torque (MBT) timing was applied. The results show that excellent steady-state and transient performance can be achieved.
