The SRM 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.

Nevertheless these 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 Innovations 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.
