School Bus BioDiesel 20%¤

School Bus Overview¤

The School Bus is engineered to transport 15 or more passengers, serving primarily in the conveyance of students to and from educational institutions.

School Bus Performance Metrics¤

  • Annual Distance (dannual): The school bus covers an annual distance of 24,000 km.
  • Average Occupancy Rate (nlpv): It boasts an average loading capacity accommodating 47 passengers per vehicle.
  • Utilization Window: The vehicle is utilized for 5.26 hours per day, translating to a 22% capacity utilization, according to the study by Duran and Walkowicz1.
  • Reference Capacity: The reference capacity, derived from these parameters, is calculated to be 585.31 passenger-kilometers per hour (pkm/h), utilizing the formula:
\[ ref_{size} = \dfrac{d_{annual} \cdot n_{lpv}}{8760 \cdot c_p} \]

Where cp represents the capacity utilization percentage. Where the denominator reflects the total hours in a year multiplied by the capacity utilization factor.

B20 Biodiesel¤

B20 Biodiesel is a blend that includes 20% biodiesel with 80% petroleum diesel. It offers a balance between the environmental benefits of biodiesel and the cost of traditional diesel. This blend aids in decreasing greenhouse gas emissions while utilizing existing diesel infrastructure. Only blends of biodiesel and petroleum diesel containing 7% vol. or less of biodiesel can be used in diesel engines without modification. Pure biodiesel (B100) requires engine modifications to avoid maintenance and performance problems.

Model Remarks:¤

The model treats vehicles that use biodiesel and those that use traditional diesel as equivalent in technical aspects. It is worth noting that in the current version of QC EnergyScope, biodiesel is treated the same as diesel and will require modification in a future version.
