Combustion Simulation

Design and optimize new combustion processes and adapt to alternative engine fuels

The LMS Imagine.Lab Combustion simulation solution supports the design and optimization of conventional and innovative combustion processes as well as the adaptation to alternative engine fuels. This solution helps you:

  • Set up the cylinder geometry (piston shape, head, location of injectors and plug)
  • Optimize engine parameters such as advance, turbulence (swirl/tumble/squish), lambda control or injection split for different fuel types
  • Study advanced combustion processes including homogeneous charge compression ignition (HCCI) and controlled auto-ignition (CAI)

Combustion processes are increasingly more complex. Along with customer desires for higher engine response and lower noise levels, you also have to meet stringent emission standards. Engine designers are looking for alternatives beyond conventional gasoline spark ignition (SI) and diesel compression ignition (CI) combustions.

The Combustion simulation solution provides an efficient way for you to investigate transient engine behavior by using an unparalleled multi-domain system simulation approach. The IFP-engine library provides dedicated components for combustion simulations and can be seamlessly coupled with 3D combustion codes and models (such as IFP-C3D).

The Combustion simulation solution provides the ideal tool set to analyze dynamic behavior of all combustion processes and enables flawless 3D calculation integration in a system approach. Dedicated libraries come with state-of-the-art 1D and 3D models suitable for various applications – from large diesel to high-rev gasoline engines.
