The simulation computes torque, RPM, and throttle response from user-defined engine components and parameters, with keyboard controls for ignition, starter, throttle, clutch, gears, and simulation speed. The engine behavior is modeled by assembling reusable mechanical parts like cylinders, crankshafts, and exhausts with adjustable parameters, using a custom node-graph scripting language that defines engine components as interconnected nodes. Audio is generated in real time by processing engine parameters through a directed graph of nodes that compute torque, RPM, and sound, while a virtual dynamometer measures horsepower and torque by holding the engine at a target RPM against a simulated load. Engines are loaded from external configuration files by specifying a path and node name, allowing modular swapping of engine definitions. The diagnostic error reporting system checks script parsing and execution for argument mismatches, undefined references, and syntax errors to aid debugging. ## Tags ### Part of an Awesome List - [Combustion Engine Simulators](https://awesome-repositories.com/f/awesome-lists/devtools/simulation-and-modeling/combustion-engine-simulators.md) — Models internal combustion engine mechanics with configurable components for torque, RPM, and throttle response. - [Mechanical Dynamics Simulators](https://awesome-repositories.com/f/awesome-lists/ai/physics-simulation/mechanical-dynamics-simulators.md) — Computes engine response by simulating throttle, load, and inertia dynamics in real time. ### Development Tools & Productivity - [Vehicle Simulation Controls](https://awesome-repositories.com/f/development-tools-productivity/keyboard-interaction-controls/vehicle-simulation-controls.md) — Controls ignition, starter, throttle, clutch, gears, and simulation speed using keyboard inputs. - [Engine Definition Importers](https://awesome-repositories.com/f/development-tools-productivity/project-imports/external-file-importers/configuration-file-importers/engine-definition-importers.md) — Imports engine files by path and activates them by node name in the main configuration.
