Gas Engine Testing

As part of the energy transition and an increasing customer demand for environmentally friendly powertrains and propulsion solutions, gaseous fuels are attracting particular attention in the field of personal mobility, but also for industrial and marine applications. FVTR contributes to this energy transition with its work in the research area of gas and alternative fuel engines. A comprehensive gas infrastructure and three test benches with a wide power range are currently available for your project ideas.

Challenges in Gas Engine Development

Natural gas resp. methane has a huge potential to address the pressing issues of CO2 reduction either via inherent lower carbon content than liquid fossile fuels or in future via a synthesis pathway out of renewable energies.

Several combustion technologies are possible: lean-gas for stationary application, dual-fuel for shipping, stoichiometric w/ EGR or even diffusion controlled for car and truck applications.

Some of the main challenges are:

  • High specific power
  • Methane slip
  • Knocking and misfiring with homogeneous combustion processes
  • Cryogenic components for high-pressure gas systems

We are looking forward to support you with your developmentprojects regarding gas existing engines and related components as well as completely new concepts.

Our Development Services

  • Development of gas powered light and medium duty engines
  • Analyzation of CNG and LNG combustion processes at our test benches
  • Test of exhaust gas treatment components under combustion gas operation
  • Simulation based development of combustion chamber designs and components
  • Investigation of the influences of gaseous fuels on lubricants
  • Development of operating strategies for gas engines
  • Component testing

Gas Infrastructure

Our available gas infrastructure is based upon natural gas from the public grid. Three different pressure levels are achieved by a 20 bar screw compressor, a 250 bar piston compressor and a 600 bar pressure transducer. With these systems a maximum mass flow of 150 kg/h can be supplied.

Furthermore, we have the opportunity to add CO2 and LPG to the base natural gas in order to control the relevant properties like methane number and heating value in wide ranges. This state of the art gas mixing facility is already prepared to be upgraded with another gaseous component – like for example H2.

The LPG used for the gas mixing can also be provided at various test benches in liquid or gaseous form. For the analysation of the incoming gas quality as well as for the control of the gas mixing process our gas infrastructure is equipped with an in-situ gas chromatograph. This allows us to analyse up to 11 species in the fuel gas flow directly upstream of the test engines.

Through the cooperation with other working groups in the company, engine issues can be dealt with holistically:

  • Investigation of injection and mixture formation processes at own and specialized injection test benches
  • Chemical analysis of customer fuels and lubricant samples
  • Simulation of mixture and combustion processes
