R&D project: Construction of a hot-film anemometer for use in exhaust gases of internal combustion engines

BMBF Logo english

This project is conducted under the acronym “AMAZING” and is supported by the German Federal Ministry of Education and Research (BMBF). It is listed under the project number 16ES0595.

The project goal is to develop a pulsatile mass flow sensor, which allows both a determination of the exhaust gas mass flow of combustion engines, and is suitable for use in portable emission monitoring systems. The aim is to select a material-hybrid approach from miniaturized, highly robust, ceramic sensor elements and thermally decoupled housing as well as an adapted, high-temperature construction and connection technology. For control, measurement and signal processing, a control and evaluation electronics is developed which ensures the use in harsh environmental conditions. On the basis of the developed sensor, the next step will be to develop an EGR system that will be integrated into suitable engine test benches and evaluate its influence on fuel consumption and emissions. The work plan consists of a total of 10 segments. These are described separately in the Sub-project description and are referred to as WP = work package.

  • WP 01: Requirements analysis, compilation of specifications and specifications
  • WP 02: Development of sensor housing and fixtures for the measuring element
  • WP 03: Cooperation in the creation of the simulation model, heat transfer, etc.
  • WP 04: Design of laboratory model for EGR and PEMS applications
  • WP 05: Connection of the electronics and creation of the algorithms
  • WP 06: Test bench for EGR and PEMS: rough conception, participation in the construction
  • WP 07: Calibration
  • WP 08: Construction and testing of the entire system in the EGR test bench
  • WP 09: Final evaluation
  • WP 10: Patent searches, publications (German)
