Combustion, airpath & aftertreatment

Airpath, combustion and aftertreatment systems

Ricardo has extensive experience in developing airpath, combustion and aftertreatment systems for use in all types of engine, from high-performance gasoline engines to the largest marine diesel and gas engines.

Air, combustion and aftertreatment system development for performance, fuel economy and reduced emissions

Sophisticated tools, particularly Computational Fluid Dynamics (CFD), are used to optimize the development process, yielding the highest quality results over shorter timeframes.

Integrated Model Based Development

  • Highly adaptable and customisable modelling capability
  • Identifies the critical trade-offs including hardware and control interaction
  • Reduces hardware phase time and cost through virtual system optimisation and pre-calibration
  • Assesses internal combustion engines, transmission and electrification options
  • Studies legislative cycles and real-world driving with varying driver profiles.

Our development processes include:

  • Air path development
    • 1D gas-dynamics simulation
    • Valve events optimisation
    • Boost system selection including electrification
    • Intake and exhaust development including coupled 1D/3D methods
  • Combustion system development
    • Combustion-system target setting
    • Spray characterisation
    • In-cylinder 3-D combustion CFD
