Air Path Estimation on Diesel HCCI Engine

Abstract

<div class="htmlview paragraph">In this paper, we address the problem of air path variables estimation for an HCCI engine. Two observers are proposed. Both rely on physical assumptions on the combustion, but use different sensors. After proving convergence in the two cases, we carry out comparisons based on simulation results. We stress the impact of two particular additional sensors on obtained performance: fresh air and EGR temperature probes.</div>
