Virtually hack your engine | Hackaday


It’s no secret that we love to simulate circuits before we build anything, and there are many great tools for that. But what about those of us who work on cars? Well, you could try Engine-Sim, a real-time combustion engine simulation. In all honesty, the program openly admits that it’s not accurate enough to do engineering or engine tuning. But on the plus side it has audio output and is at least good as a teaching tool to show how an engine runs and how different parameters can affect it. Below is a video of the tool.

[Ange-Yaghi] mentions that the code was mainly used to run the YouTube demo. However, the readme suggests that it could be better – or at least different – and collaboration to make it better is welcome.

We know firsthand that a simulator doesn’t have to be absolutely accurate to give you a feel for how things work. Finally, most simulations for electronics don’t always model things like wire resistance and parasitics. We’ll leave it to the engine connoisseurs to tell us if this simulator is close enough to be useful.

The keyboard shortcuts allow you to toggle the ignition, change gears with a clutch, and change the throttle. We’d love to see a screen of data like this for our actual car engine, and maybe you could get close with one of those bluetooth dongles.

We remember a watch that was also a kind of engine simulator. If your simulation dreams are more electronics focused, there are plenty of options there.
