Flow modelling simulation

The perfect combination for you, the perfect lubrication mixture from us.

Lifting the lid
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 online. But what does an engine look like from the inside while it's in operation, during the fuel combustion process? What does it look 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 this question and, in doing so, optimise our engine technology.

Reduce wear
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. Flow modelling simulation is performed to make sure that the engine compartment in a STIHL tool is perfectly lubricated and 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.

Practical maths
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 formulae, which are used to calculate fluid movement in the engine compartment. This allows flow modelling engineers and design engineers to work together in optimising 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.
