The SRM Engine Suitesrm engine suite

The SRM Engine Suite is a virtual engineering design tool for simulating the performance and exhaust gas emissions from internal combustion engines. Example applications have included motorcycle, passenger car, motor sport, truck, locomotive, marine and power generation.

Through integrating the srm engine suite, our growing customer base has benefited by adding a well validated, robust and state-of-the-art library of sub-models to their design process enabling unrivaled optimisation of fuel characteristics and engine design and control parameters.

All projects & post-processing is handled through the use of CMCL Innovation’s newly improved SRM Engine Suite GUI, offering intuitive and user friendly methods to setup your simulations , export/visualise data, and run advanced post-processing analysis tools.

New Additions

Through our on-going product development program and through customer feedback and projects, the tool has the following new capabilities.

  • More reactors: Iso-thermal, liquid fuel injection, cetane test, octane test, oil droplet ignition engine, engine breathing, dual fuel engine.
  • More fuel models: Hydrogen, toluene reference fuel, ethanol, dual fuel (natural gas & diesel).
  • Fast solvers: Chemistry solvers (5-15 times speed-up), mixing and chemistry sub-model flexibility.
  • Advanced fuels, combustion and emissions simulations using the srm engine suite
  • Improved visualisations: Plot line, scatter, bar, pie,  and raw tabular data, save custom charts, modify titles and colours, import *.csv files and compare with your simulations.
  • Improved sensitivity analysis: Easy configuration, customisation and post processing.
  • Advanced turbulence models: Accounting for swirl, tumble, injection and squish effects.
  • More accurate particulate matter (PM) prediction: New wall impingement sub-model.
