IC Engine Experiment Data

This experiment measures and analyzes the performance of a single-cylinder IC engine under varying loads.

Formulas Used:

BP (kW): (2 * π * RPM * Torque) / (60 * 1000)
Fuel Consumption (kg/min): (Fuel Consumption (ml/min) / 1000) * Fuel Density
SFC (kg/kWh): Fuel Consumption (kg/min) / (BP (kW) * 60)
Energy Input (kW): Fuel Consumption (kg/min) * Calorific Value * 1000 / 60
Thermal Efficiency (%): (BP (kW) / Energy Input (kW)) * 100
