Woodward L’Orange’s new injector generation – an ideal platform for the combustion of E-Fuels in large engines

Most current forecasts show a world with an increasing replacement of fossil energy by regeneratively produced electric energy. In this future world E-Fuels will play an important role for the operation of large engines for example in maritime transport and power generation.Woodward L’Orange developed an injection system which is suitable to manage a variety of „advanced“ E-fuels which may replace todays well known carbon based long-chain fuels and give additional advantages. This concept is prepared to inject Methane, Propane, Methanol or Ammonia in a DI concept and allows to design combustion engines with high power density, good operability and low greenhouse gas critical emissions.The basic injector concept will be discussed and some basic results from Gas combustion development will be shown. In addition the „scaling“ to the other E-fuels and different engine sizes will be demonstrated. This is mainly a scaling in nozzle size and some hydraulic details dependent on the thermodynamic phase state of the fuel at injection.In addition to the injector the required type of HP pumps or compressor will be shown, which are all different in design and efficiency, dependent on the used E-Fuel.Finally the complete system chains will be evaluated against each other to give an indication on the suitability for different applications.
