What you can do with this built simulation:

Drive the Vehicle: Move the Throttle Slider and swap through the Transmission Gears to alter the engine speed (RPM), torque curves, and power output (HP) in real time.
Track Engine Aging: Watch how accumulating mileage affects your Injector Clog Percentage and Oil Life on the continuous telemetry trend chart.
Observe ECU Interventions: Force the engine into extreme stress scenarios to trigger active OBD-II Fault Codes (such as engine overheating or running too lean) directly inside the diagnostics status display window.
Perform Service Actions: Use the pit-lane buttons to quickly top off the fuel tank or refresh the motor oil to clear active warning codes and restore standard operating metrics.

This python script builds an interactive, real-time Engine Simulation and On-Board Diagnostics (OBD-II) Dashboard. It uses PyQt5 to construct a sleek graphical user interface (GUI) and Matplotlib to handle live telemetry instrumentation and data graphing.

Essentially, it acts as a virtual engine dynamometer (dyno) software that lets you play the role of both a driver and a mechanic—testing how physical inputs, transmission gears, and different oil blends impact vehicle performance and component wear over time.

⚙️ Core Architecture: Component Breakdown

1. Engine Simulator (EngineSimulator)

This is the physics engine running behind the scenes. Every 100 milliseconds, it steps forward in time and calculates mathematical relationships for real-time engine behaviors:

RPM & Power Dynamics: Computes engine speed based on your throttle opening, selected gear ratios, and parasitic drivetrain friction. It then uses RPM and torque to solve for real-time Horsepower (HP).
Thermal Management: Simulates heat build-up. Keeping the engine pinned at high RPMs generates heat, while driving faster forces ambient air into the radiator to cool it back down.
Fluid & Component Degradation: Simulates long-term wear. As you drive, fuel is burned, oil degrades according to its specific viscosity profile, and the fuel injectors gradually clog up from mileage.

2. ECU Control Module (ECUController)

This acts as the engine's onboard computer. It monitors incoming sensor data from the simulator and performs two critical roles:

Electronic Safety Limiter: If the engine revs past its safe threshold (which changes dynamically based on the weight of the motor oil you choose), the ECU overrides the system and cuts the throttle to zero to prevent mechanical failure.
OBD-II Fault Logging: It actively flags industry-standard Diagnostic Trouble Codes (DTCs) if any system attributes fall out of safe operating limits:
- P0217: Engine Coolant Overheating.
- P0171: Fuel System running too lean (triggered by high injector clogging and falling fuel pressure).
- P0230 / P0300: Low fuel reserves and subsequent engine misfires when the tank dries out.
- P017C: Oil service reminder when life drops below 10%.

3. Animated Instrument Cluster (GaugeCanvas)

A specialized graphics module that turns raw numbers (RPM, Torque, HP, and Coolant Temperature) into beautiful analog dial gauges. It dynamically sweeps indicator needles and divides its background arcs into standard color zones: a green safe range, a yellow warning buffer, and a redline zone.

4. Linear Telemetry History (TelemetryCanvas)

A rolling time-series graph. It maps out your Fuel Level and Injector Clog Percentage over time. To keep the app running light and fast, it manages data within a rolling 50-point buffer, discarding old data points as new ones pour in.

5. Data Export Matrix (EngineDashboard)

The user dashboard that links all the blocks together. It translates mechanical slider actions into engine states, displays a digital metrics readout panel, and contains an Export Data Button. Clicking it flushes your entire history out of the app's temporary memory and compiles it into an open-format CSV spreadsheet for data tracking.

How to Test Scenarios in the Simulation

When you run the app, you can experiment with specific automotive stress tests:

The Redline Burnout: Leave the vehicle in Gear 1 and pin the throttle to 100%. You will watch the RPM slam into the rev-limiter, power drop off, and temperature spike until a bright red P0217 Overheating fault pops up in the diagnostics window.
The Fuel Starvation Test: Let the engine run over time. The fuel level trendline will slope down on the graph. When the tank falls below 1.5 gallons, a P0230 Low Fuel warning triggers, and once it hits absolute zero, a P0300 Engine Misfire code flags as the RPM drops to a dead stop.
The Pit Stop Overhaul: If your injectors clog up or your oil wears out from high mileage, you can click "Refuel Vehicle" or "Change Motor Oil" to reset the data matrices, clean out the active trouble codes, and watch the system instantly recover.

⚙️ Core Architecture: What Each Module Does

1. Engine Simulator (EngineSimulator)

This is the mathematical model running under the hood. Every 100 milliseconds, it calculates physics-based engine behaviors:

RPM & Load: Calculates how fast the engine revs based on throttle application, selected gear ratios, and parasitic mechanical resistance.
Thermal System: Simulates heat build-up. High RPMs generate heat, while driving faster forces air into the system to stabilize cooling.
Fluid Dynamics & Wear: Tracks physical mileage. As the vehicle drives, fuel drops, injector clogging rises due to accumulated miles, fuel pressure drops, and oil efficiency degrades based on the active oil's thickness profile.

2. ECU Control Module (ECUController)

This acts as the engine's onboard computer. It actively scans sensor arrays coming from the simulator and performs two critical roles:

Safety Limiter: If the engine surpasses safe parameters (e.g., maximum RPM thresholds tailored to specific oils), the ECU cuts throttle back to 0 to prevent engine failure.
Diagnostic Code Generation: It flags automotive Diagnostic Trouble Codes (DTCs) in real time if parts fall out of tolerance:
- P0217: Engine overheating.
- P0171: System lean due to clogged fuel injectors.
- P0230 / P0300: Low fuel levels and fuel starvation misfires.
- P017C: Periodic service warnings indicating oil life is expiring.

3. Animated Instrument Cluster (GaugeCanvas)

A customized data visualization tool that renders analog dial gauges inside the app. It translates live performance data (RPM, Torque, HP, and Temperature) into polar coordinate sweeping needles. It also colors target arcs—allocating safe green zones, warning yellows, and a redline zone.

4. System Status History Trends (TelemetryCanvas)

A rolling telemetry monitor. It records systemic wear variables over time and displays them on a linear chart. To keep your system memory footprint low, it acts as a rolling buffer, keeping only the 50 most recent records and smoothly purging older data points.

5. Master GUI Interface (EngineSimulationDashboard)

The visual panel bridging user control and software code.

It wires together interactive hardware widgets (a throttle slider, gear selectors, oil configuration options, and flushing tools).
It aggregates simulation values into a cleanly structured digital dashboard display.
Session Persistence: It features a data logging compiler. Clicking the export option flushes all transient engine timelines onto your system as an open-format CSV spreadsheet for external spreadsheet auditing.
