Week-4 Challenge WOT Condition Part-2
Mapped model
- In a mapped model behaviour of the system is described using predefined maps or tables that relate input parameters (such as throttle positions, speed, torque) and output variables (power,efficiency,emissions). These maps are typically generated through experimentaal testing.
- Mapped models are computationally efficient and suitable for steady state simulations where the system operates with in a limited range of operating conditions.
- The lack the ability to capture transient behaviours and responses to sudden changes in operating conditions.
Dynamic model
- The behaviour of the system using mathematical equations that represent its physical dynamics. These model incorporate differential equations that account for inertia, dynamics of mechanical components, electrical characteristics etc.
- Dynamic model are more accurate and can capture transient behaviours, such as start up, shut down, and responses to sudden load changes.
- They are computationally itensive compared to mapped model especially for complex systems and may require more computational resources.
Changing from Mapped model to Dynamic model
- To change from a mapped model to a dynamic model you would need to replace the predefined maps or tables with mathematical equations that describe the system dynamics. This may involve implementing differential equation that govern the behaviour of the system components.
- You may also need to gather additional data or information about the systems. Characteristic to accurately represent. Its dynamics in the dynamic model.
Changing from Dynamic model to Mapped model
- If you want to switch from a dynamic model to mapped model with the dynamic model need to develop empirical maps or tables based on the results of simulations or experiments conducted with the dynamic model.
- This process involves identifying the key input - output relationships and generating maps that adequately represent the systems behaviour across various operating conditions.
Miles Per Gallen
Calculating Miles Per Gallen (MPG) involving dividing the number of miles travelled by the amount of fuel consumed.
MPG=Miles travelled/Gallons fuel consumed
Factors are:
1. Engine efficiency: This refers to how efficiently the engine converts fuel into mechanical energy. More efficient engines will require less fuelfor the same amount of work done.
2. Vehicle weight: Heavier vehicles typically require more fuel to move. Compared to lighter vehicles.
3. Aerodynamics: The shape of the vehicle affects air resistance, Which in turn affects fuel consumption. Vehicle with better aerodynamic generally use less fuel.
4. Driving Conditions: Fuel consumption can vary based on factors like speed, accelaration, and terrain. Stop and go city driving tends to consume more fuel compared to steady highway cruising.
5. Fyuel type: different types of fuel (gasoline, diesel, electric) have different energy density and combustion characteristic affecting fuel consumption.
6. Vehicle maintenance: Poorly maintained vehicles may have inefficient engines, Underinflated tires or other issues that increse fuel consumption.
7. Driving habits: Aggressive driving behaviours such as rapid accelaration and hard breaking can increase fuel consumption.
8. Enviromental factors: Temaperature, humidity, and altitude can also affect fuel consumption.
