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 include motorcycle, passenger car, motorsport, 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 unrivalled optimisation of fuel characteristics and engine design and control parameters.
