Steady-state warm calibration of the PHOENICE prototype engine was carried out at relevant engine load points on IFP Energies nouvelles‘s engine test bench. A specific sequential methodology of optimization has been set to achieve the lowest fuel consumption while minimizing the pollutant emissions. This calibration has been performed on ~40 operating points: operating points defined as …
The PHOENICE EATS comprises two sections: a close-coupled section, primarily designed to control gaseous emissions under cold-start and stoichiometric (λ=1) conditions, as well as particulate matter, and an underfloor section, which is necessary for NOx conversion under lean conditions and to reduce the concentration of additional pollutants such as ammonia. The results of exhaust after-treatment …
PHOENICE latest open access paper about the design and development of the PHOENICE engine concept and the preliminary optimization of the engine calibration is out! Titled “A Synergic Use of Innovative Technologies for the Next Generation of High Efficiency Internal Combustion Engines for PHEVs: the PHOENICE Project”, the paper is available open access here: https://saemobilus.sae.org/content/2023-01-0224 This …
The PHOENICE project developed a fully physical virtual test rig to support the calibration of the highly efficient spark ignition engine of the project. Indeed, the availability of a reliable simulation platform is essential to effectively exploit the combination of the several features introduced to achieve the project target of 47% peak gross indicated efficiency, …
The first engine prototype has been assembled and installed at the IFPEN test bench! Most of the new features, including the high-pressure injection system, the long-route EGR loop, and the rebuilt airline embedding the new WCAC, have been successfully implemented. On the other hand, the baseline turbocharger and exhaust aftertreatment system were used for the …

The concept embeds a high-speed electric motor (>200k rpm) into the core of the Turbocharger which is powered and controlled by Garrett’s own inverter. In this configuration, the inverter takes in DC current from the vehicle network and switches it into 3 phase AC to drive the motor. Powerful algorithms switch the phase currents at …

The manufacturing and on-bench characterization of waste heat recovery systems (WHRS) completed by Marelli Europe! Two different devices were considered: Exhaust heat recovery system (EHRS) for engine fast warm-up effect: the device consists of a heat exchanger (HE) and a by-pass tube+valve. When by-pass is closed, exhaust gas passes through the HE and transfers part …
Compared to the baseline engine provided by Centro Ricerche Fiat (CRF), the main improvements are:– New cylinder head design implementing SWUMBLE™ motion (IFPEN)– Increased compression ratio from 10,5 : 1 to 13,6 : 1– VNT (Variable Nozzle geometry Turbo) e-Turbo provided by Garrett Motion and replacing Waste Gate turbocharger– Increased injection pressure from 200 to 350 …
