Short communication: The effects of not controlling the hydrogen supplied to an internal combustion engine

Abstract

Recent research works have focused on analyzing the performance of the hydrogen-fueled internal combustion engines. In this short communication, we present the results of using hydrogen-enriched gasoline in an internal combustion engine without modifying the fuel control algorithm. For this purpose, two different analyses are presented and experimentally validated. In the first analysis, the internal combustion engine is fueled with hydrogen-enriched gasoline using the engine electronic control unit. On the other hand, the second analysis uses this fuel (gasoline + H2), and a control scheme based on model predictive control with constraints considering the hydrogen ratio. The experimental results showed that by using the engine electronic control unit, the gasoline consumption increases by 7.18%. And using the model predictive control, gasoline consumption can be reduced by 2.2%.
