Title: Delphine Bresch-Pietri: Innovator in Combustion Engine Control

Introduction

Delphine Bresch-Pietri is a notable inventor based in Vincennes, France. She has made significant contributions to the field of combustion engine control, holding 2 patents that showcase her innovative approaches to improving engine efficiency and performance.

Latest Patents

Her latest patents include a method of controlling a combustion engine from the estimation of the burnt gas mass fraction in the intake manifold. This method involves measuring the fresh air flow rate or burnt gas flow rate upstream from the mixing space where these gases combine. The burnt gas mass fraction is estimated based on this measurement and a model of the mixing dynamics. A transport delay between the mixing space and the intake manifold is also estimated, allowing for real-time combustion control based on the burnt gas mass fraction.

Another significant patent is a method of controlling an EGR valve integrated into an EGR circuit of a combustion engine. This invention outlines a systematic approach to controlling the EGR valve by measuring pressure differences in the exhaust gas recirculation circuit and calculating an opening set point for the valve based on these measurements and a burnt gas fraction set point.
