Engine displacement (often given in liters) is related to power output (horsepower), but many other factors influence the horsepower an engine produces, including:
* Engine design: The efficiency of the combustion process, the number of cylinders, the valve design, etc. all affect horsepower.
* Fuel type and quality: The energy content of the fuel significantly impacts power output.
* RPM (revolutions per minute): Horsepower is usually specified at a particular RPM.
* Turbocharging or supercharging: These systems increase the amount of air and fuel entering the engine, boosting horsepower.
In short, knowing the engine displacement in liters gives you some indication of the *potential* horsepower, but it's not a reliable conversion. You need much more information to determine the actual horsepower.
