this is a highly detailed physics simulator of an engine, it has 4 stages just like a real engine, them being: 1- injection 2- compression 3- combustion 4- exhaust the simulation simulates every single aspect of it with precise calculations with a topping of customizable engine characteristics! simulation will simulate all the things according to your settings and the output will be dependent on these factors.
(USE TURBO MODE!!!(it WILL work without it but turbo mode makes it run much smoother)) enable turbo mode with pressing the green flag while holding shift on your keyboard to start the engine, you need to: 1: turn on the ignition, it will appear green when its on 2: turn on the throttle a bit for fuel income to the combustion chamber 3: hold space to make the engine start, it may take a few tries before it starts to spin by itself, so be patient! and thats it! you engine must be running and ready to rev! have fun!
