Testing Powertrains to move the Future

Combustion engines and operating supplies

„For more than five decades, KST has been standing for experience, competence and flexibility in the development and testing of internal combustion engines.”

We meet the ever-increasing requirements on combustion engine and component testing with flexible automation systems and state-of-the art measurement technology.

Range of services: Combustion engines

Our range of services in the field of combustion engines for passenger cars and commercial vehicles covers the following points:

  • Validation of dynamic standard cycles with emission measurements
  • Test beds for hybrid powertrain tests
  • Test beds for hybrid powertrain tests including the use of original vehicle batteries
  • Cold start and thermal shock test tests
  • Functional analyses of the engine mechanics on combustion and hybrid engines
  • Functional development work on exhaust gas aftertreatment systems (particulate filters, SCR, …)
  • Development and validation work of exhaust gas aftertreatment systems on the test bed (in original vehicle positioning), operating vibration tests, durability with resonance tracking, …)
  • Tilt analyses for optimisation of oil supply and blow-by system (tilt rig capacity up to a 55° angle)
  • Certifications

Synthetic fuels / operating fluids

Synthetic fuels/e-fuels represent a vast potential for the decarbonisation provided they are synthesized in a CO2-neutral manner and can be used in existing fleets, for example by adding them to fossil fuels.
