Term: Nov 2014 to Oct 2022

The Professor Urbano Ernesto Stumpf ERC was part of the Engineering Research Center Program (CPE) between 2014 and 2022. It was funded by FAPESP and Peugeot-Citroën (PSA, now part of Stellantis) and hosted by UNICAMP’s Biofuel Engine Laboratory (1st phase) and IMT’s Mauá School of Engineering. It involved scientists from the University of São Paulo (USP), Aeronautics Institute of Technology (ITA), Institute Mauá of Technology (IMT), and State University of Campinas (UNICAMP).

The team covered a comprehensive range of technical subjects relating to biofuel engines, from basic physical and chemical phenomena to the entire vehicle. The first phase (2014-2019) focused on basic phenomena, including a conceptual study of an advanced ethanol-fueled engine. The second phase (2019-2022) focused on the fine tuning of 1D and 3D simulation tools, and their application to ethanol engines.

This ERC also trained researchers for academic and industrial activities, and to establish technical and scientific collaboration among research groups and the industry.

More recently, it coordinated testing of the latest generation of engines developed by the group, and designed a methodology for 3D computer simulation of fluid dynamics (CFD) in internal combustion engines running on ethanol. The research team also characterized ethanol combustion in a single-cylinder optical engine and identified several key factors that modify the injection and combustion behavior of ethanol compared to gasoline.


1. Exploratory experimental tests for an ethanol engine.
2. Fundamental studies on mixture preparation and turbulent combustion of ethanol in engines.
3. Spray Combustion of hydrated Ethanol for MPFI Engines.
4. Thermodynamic simulation of indicated performance for ethanol engines.
5. Simulation of DI ethanol spray behavior and combustion evolution via 3D CFD, with models validated against experimental results.


Stumpf Engineering Research Center helps orient Stellantis’s decisions on ethanol in Brazil
The automotive giant resulting from the PSA-Fiat Chrysler merger is partnering with FAPESP in this ERC, which is integrated with Stellantis’s global network of science labs.

Less-polluting cars
The R&D Center of the PSA Group in Brazil works to improve ethanol engines and develop parts made with recyclable materials.
