How to make your own engine based on another mod: 1) We find a mod with engines (or any other parts) for the desired car and open the archive with the mod. 2) Go to the folder " Vehicles "then in the" name of your car "(in my case, the engines are in the folder" Common"), look for a file with engines (usually called" engine") and open it with Notepad. An example of how it looks in the engine jbeam. 3) Next, depending on what you want to change: 1) If you want to change the torque (power is built automatically by torque), go to the section "MainEngine" and there you will see 2 columns: the first-the engine speed, the second-the torque. We only need the torque (tip: if the cutoff (maximum rpm) is higher than the highest number in the left column, just copy and paste the same lines under them and change the number of revolutions). Now just change the torque the way you want. 2) If you want to change the name of the part (any part) change it in the paragraph that is specified in the screenshot. 3) If you want to change some parameter of the engine (below I will write what is responsible for what) move to the item specified on the screenshot. idleRPM - engine idle. maxRPM - maximum engine RPM (rounds per minutes) RevLimiterType - type of rev limiter requiredEnergyType - type of fuel. The rest I don't know (and then complement). 4) Oil volume (red arrow) - the more, the harder it is to overheat the engine 5) cylinderWallTemperatureDamageThreshold (blue arrow) - the temperature at which the engine overheats. 6) highShiftUpRPM (yellow arrow) - the speed at which the transmission increases the transmission (kickdown). There are all basic parametrst hat you need to know. 4) Slots: If you're newbie, you better stay out of it!!! First "" is name of slot . Second "" is default part Third "" is description If you need to change the default gearbox (e.g. 5-speed manual to 9-speed automatic) insert the second "" name (shown in the screenshot) of part (in my case "9g_tronic_pickup") You can also change the name of the slot (I do not advise to do this). If you do not understand something do not hesitate to write me in private messages (can be in Russian), I will try to answer all questions (and not only). Will soon release a tutorial for the transmission. Second tutorial: https://beamng.com/threads/how-to-make-your-own-transaxle-based-on-another-mod.61166/
You couldn't look at the wiki? It very clearly explains what all engine variables do and how to use them.
It is the easiest way to get your own engine in the game. And wiki is not clear for beginners. But if you can make it better you are welcome.
