## Idling Fuel Consumption Formula

The following two example problems outline the steps and information needed to calculate the Idling Fuel Consumption.

**IFC = ES * .6**

Variables:

- IFC is the Idling Fuel Consumption (L/hr)
- ES is the total engine displacement (liters)

To calculate Idling Fuel Consumption, multiply the size of the engine displacement by .6.

## How to Calculate Idling Fuel Consumption?

The following steps outline how to calculate the Idling Fuel Consumption.

- First, determine the total engine displacement (liters).
- Next, gather the formula from above = IFC = ES * .6.
- Finally, calculate the Idling Fuel Consumption.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

total engine displacement (liters) = 25

IFC = ES * .6** **= ?
