Combustion efficiency Solution

STEP 0: Pre-Calculation Summary

Formula Used

Combustion Efficiency = Heat Added by Combustion per Cycle/(Mass of Fuel Added per Cycle*Heating Value of the Fuel)
η_c = Q_in/(m_f*Q_HV)
This formula uses 4 Variables

Variables Used

Combustion Efficiency - Combustion Efficiency is defined as the actual heat input to the theoretical heat input in the engine cylinder.
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.
Mass of Fuel Added per Cycle - Mass of Fuel Added per Cycle is defined as the fuel that gets combustible in one cycle.
Heating Value of the Fuel - (Measured in Joule per Kilogram) - Heating value of the fuel is defined as the chemical energy per unit mass of the fuel.

STEP 1: Convert Input(s) to Base Unit

Heat Added by Combustion per Cycle: 150 Kilojoule per Kilogram --> 150000 Joule per Kilogram (Check conversion here)
Mass of Fuel Added per Cycle: 0.005 --> No Conversion Required
Heating Value of the Fuel: 50000 Kilojoule per Kilogram --> 50000000 Joule per Kilogram (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

η_c = Q_in/(m_f*Q_HV) --> 150000/(0.005*50000000)

Evaluating ... ...

η_c = 0.6

STEP 3: Convert Result to Output's Unit

0.6 --> No Conversion Required

FINAL ANSWER

0.6 <-- Combustion Efficiency

What is combustion efficiency?

Combustion efficiency is the rate at which an engine converts fuel into energy. Particularly with heavy fuels with high-energy densities — diesel, fuel oil, bunker fuel, etc. The combustion efficiency increases with increased excess air - until the heat loss in the excess air is larger than the heat provided by more efficient combustion.

How to Calculate Combustion efficiency?

Combustion efficiency calculator uses Combustion Efficiency = Heat Added by Combustion per Cycle/(Mass of Fuel Added per Cycle*Heating Value of the Fuel) to calculate the Combustion Efficiency, The Combustion efficiency formula is defined as a measure of how effectively the heat content of a fuel is transferred into usable heat. Combustion Efficiency is denoted by η_c symbol.

How to calculate Combustion efficiency using this online calculator? To use this online calculator for Combustion efficiency, enter Heat Added by Combustion per Cycle (Q_in), Mass of Fuel Added per Cycle (m_f) & Heating Value of the Fuel (Q_HV) and hit the calculate button. Here is how the Combustion efficiency calculation can be explained with given input values -> 0.6 = 150000/(0.005*50000000).
