Injection Control

Diesel engine fuel injection control is presented as a feedback based online optimization problem. Extremum seeking (ES) approach is used to address the online optimization formulation. The cost function is synthesized from extensive experimental investigations such that the indicated thermal efficiency of the engine is maximized while minimizing the NOx emissions under external boundary conditions. Knowledge of the physical combustion and emission formation process based on a pre-calibrated non-linear engine model output is used to determine the ES initial control input to minimize the seeking time. The control is demonstrated on a hardware-in-the-loop engine simulator bench.

Engine Power

The diesel engine power demand of the start condition can be separated into two parts including resistance overcoming and acceleration realization for the reason that there is no power output during the starting process. The present paper mainly focuses on the fuel injection quantity control based on the engine power demand especially the acceleration demand for the resistance force is fixed for a specific engine, and the starting acceleration velocity is set as a target curve so that the acceleration process can also be fixed. The feasibility of the start control strategy proposed in this paper was verified by a comparison of the traditional starting control with a constant fuel quantity, and starting performance of the target acceleration based control shows predominance to the constant quantity control. And then the comparison between various starting acceleration processes, which was realized by the settings of acceleration curve slope factor, was conducted and results showed that the acceleration processes with higher slope factors perform better.

Three reasons of the deviation of the fuel injection quantity for the electronic fuel injection (EFI) motorcycle engine during the transient conditions were analyzed, including the presence of fuel injection dead time, the engine load measurement deviation and the existence of fuel film attached to the inlet pipe wall. The control strategy of fuel film compensation was studied at conditions of starting, acceleration and deceleration, which was based on the changes of engine velocity, inlet air pressure and inlet air temperature. During the transient condition, the basic fuel film compensation and correction coefficient were calibrated at motorcycle dynamometer, and the modified fuel film compensation MAP were achieved correspondingly, in order to keep the excess air coefficient stable.
