Challenges in Light & Medium Engine Development

In our opinion, the high efficient combustion engine is an elementary key element on the way to an energy revolution in the mobile transport sector. To reach the CO2 reduction goals of the EU and the Paris climate agreement even further development efforts will be needed. Looking to the long-term future of traditional engines, we think that renewable and climate neutral fuels will still be burned in internal combustion engines, because of their benefits in energy density, infrastructure, availability and the efficiency of the engines itself. Against this challenging and fascinating background, we would be pleased to accompany you in your devlopment projects.

Fuel Infrastructure

In addition to conventional liquid fuels, our fuel infrastructure also offers the possibility of using bio-fuels of various qualities and special fuels at the engines:
  • Gasoline according to DIN EN228 and gasoline blends
  • Diesel according to DIN EN590 and diesel blends
  • Bio Diesel: B30, B100, FAME
  • Special fuels: methanol, ethanol, HVO, OME, DME
  • Natural gas at different pressure levels: 20, 250, 600 bar
  • Gas mixing facility: addition of CO2 and C3H8 to the natural gas 

Test Beds and Equipment

  • Test bed dynos by Schneider/Elin up to 220 kW
  • Test bench automation by AVL Puma
  • Fuel conditioning and Measurement by AVL solutions
  • INCA tool boxes for application work
  • AVL ISAC 400 driving simulator for automatic and endurance testing
  • State of the art indication systems by AVL/Kistler
  • Tailor made and open engine control unit architecture for single cylinder research engines

Exhaust Gas Analyzation

For the investigation of emission-relevant components or operating strategies, modern exhaust gas analyzing systems are available:
  • Certification-relevant measuring systems (FID and CLD)for NOx, CO2, HCs
  • FTIRs for the measurement of up to 24 special gases like N2O, NH3 and SO2
  • Determination of FSN with smokemeter
  • Mobile particle measuring station: particle concentration, number and size
