What is an MR file?

An MR file is a script used by Engine Sim, a vehicle engine simulation program developed by AngeTheGreat. It contains instructions written in a simple text-based scripting language that defines an engine's components, performance parameters, and behavior. These instructions can describe aspects such as displacement, compression ratio, exhaust flow, and other physical properties that affect how the simulated engine operates.

Hobbyists, engineers, and students interested in learning about engine mechanics or testing virtual engine designs are the primary users of Engine Sim. They serve as both configuration files and learning tools, offering a way to explore how changing specific parameters affects performance in a safe, simulated environment.

How to open an MR file

You can open MR files with Engine Sim. When loaded in Engine Sim, the MR file, the program builds and runs a virtual model of the engine described in the script. The simulation then visualizes the engine's operation and provides real-time data, such as torque, horsepower, fuel efficiency, and sound.

Since MR files are written in plain text, you can view them with any text editor. Some options include Microsoft Notepad, Apple TextEdit, and gedit. You may need to change the .mr file extension to .txt for the text editor to open the file.

When opened in a text editor, you can edit the properties of the MR file. However, if you incorrectly edit the file, you may inadvertently corrupt the script.
