Thermal efficiency of IC engine Solution

STEP 0: Pre-Calculation Summary

Formula Used

Thermal Efficiency of IC Engine = Work Done per Cycle in IC Engine/Heat Added by Combustion per Cycle
η_th = W/Q_in
This formula uses 3 Variables

Variables Used

Thermal Efficiency of IC Engine - Thermal efficiency of ic engine is defined as the ratio of work done per cycle to the actual heat input per cycle in ic engine.
Work Done per Cycle in IC Engine - (Measured in Joule) - Work Done per Cycle in IC Engine is defined as work done to push the piston downwards during the power stroke of the otto cycle in IC engine.
Heat Added by Combustion per Cycle - (Measured in Joule per Kilogram) - Heat added by combustion per cycle is defined as the amount of heat energy liberated from the combustion of the fuel in one working cycle.

STEP 1: Convert Input(s) to Base Unit

Work Done per Cycle in IC Engine: 100 Kilojoule --> 100000 Joule (Check conversion here)
Heat Added by Combustion per Cycle: 150 Kilojoule per Kilogram --> 150000 Joule per Kilogram (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

η_th = W/Q_in --> 100000/150000

Evaluating ... ...

η_th = 0.666666666666667

STEP 3: Convert Result to Output's Unit

0.666666666666667 --> No Conversion Required

FINAL ANSWER

0.666666666666667 ≈ 0.666667 <-- Thermal Efficiency of IC Engine
