Behind The Scenes - Flow Modelling
Have you ever wondered what an engine looks like from the inside?
OK, easy answer, you have certainly learned about the inner workings of engines in school, on the TV or from the Internet. But do you know how an engine looks like from the inside while it's in operation, during the fuel combustion process? Or, how it looks like when the fuel mix flows into the engine compartment?
Our design engineers work together closely with our flow modelling engineers to provide some answers to these questions and, in doing so, how to optimize the engine technology in our products.
There's a rule of thumb when it comes to engine performance: Friction creates wear, and wear causes performance to fall and reduces the engine's lifetime.
When it comes to processes inside an engine, anything that generates friction is the natural enemy of our engineers.
This is where flow modelling simulation is performed to make sure that the engine compartment in a STIHL tool is perfectly lubricated and the component friction levels are kept as low as possible. This process allows our engineers to see how the fuel mix is distributed in the engine compartment and how it behaves.
The engineers use 3D modelling data for our engines from the construction process. The rest of the task is a relatively complex combination of mathematical and physical formula, which are used to calculate fluid movement in the engine compartment. This allows flow modelling engineers and design engineers to work together in optimizing engine components to ensure that the lubricant is always exactly where it is required.
After all, only a perfectly lubricated engine means that you will be able to enjoy your STIHL tool over the long term.
