The formula to calculate the Horsepower Per Liter (HPPL) is:
\[
\text{HPPL} = \frac{\text{HP}}{\text{V}}
\]
Where:
HPPL – The horsepower per liter.
HP – The horsepower of the engine.
V – The engine displacement in liters.
Definition
Horsepower Per Liter (HPPL): A measure of an engine’s efficiency in terms of the power it produces relative to its size. It is calculated by dividing the engine’s total horsepower by its displacement in liters. This metric is often used to compare the performance of different engines, as it provides an indication of how effectively an engine converts fuel into power. Higher horsepower per liter values generally indicate more efficient and powerful engines.
Example
Let's say the horsepower (HP) is 300 and the engine displacement (V) is 2.5 liters. Using the formula:
