Design of an Adaptive Control to Feed Hydrogen-Enriched Ethanol-Gasoline Blend to an Internal Combustion Engine

In this work, an internal combustion (IC) engine air-fuel ratio (AFR) control system is presented and evaluated by simulation. The control scheme aims to regulate the overall air-fuel ratio (AFRoverall) in an IC engine fueled with a hydrogen-enriched ethanol-gasoline blend (E10) as fast as possible. The control scheme designed and developed in this work considers two control laws, a feedback control law to regulate the hydrogen and adaptive nonlinear control law for controlling the E10 mass flow injection. The main contribution of this work is the reduction of the number of controllers used for controlling the overall air-fuel ratio since other control strategies use two controllers for controlling the E10 mass flow injection. Simulation results have shown the effectiveness of the new control scheme.

Automated summary

This study presents and evaluates a control scheme for internal combustion engine air-fuel ratio regulation. The scheme aims to regulate the overall air-fuel ratio in an engine fueled with a hydrogen-enriched ethanol-gasoline blend as quickly as possible. The main contribution is the reduction of the number of controllers used and the effectiveness of the scheme is supported by simulation results.
