Fuel Systems

The Fuel & Injection Systems Modelling packages from Flowmaster allow you to design, simulate, optimise and validate your fuel & injection system to requirements before committing to expensive prototypes. The packages can be used throughout the product development process to understand:

  • Tank filling rates
  • Fuel pressure, flow-rates, temperatures and other performance parameters
  • Common rail fuel pressures and frequency domain analysis
  • Pump sizes and pressures in the low pressure (tank to pump) and high pressure (pump to injector) system
  • Rate Shaping; i.e. the optimisation of the fuel injector character curve (fuel delivery over time)
  • Fuel injector modelling – spring rate sizing, cavitation effects, fuel delivery characteristics etc
  • Temperature effects on the fuel rail – for example, bulk modulus

The Modelling package includes a wide range of standard and fuel & injection specific components.  A range of simulation modes enables engineers to model these complex systems in order to predict fuel system behaviour for critical design cases to ensure adequate fuel flow and pressure, accurate fuel metering, avoidance of interaction effects and control pressure transients.
