The Role of Foreign Direct Investment in Achieving Libya's Balance of Payments Equilibrium

Abstract

In internal combustion engines, thermal and chemical energy are converted into mechanical energy. Ambient weather conditions, such as air temperature, relative humidity, and altitude above sea level, affect air density and therefore the oxygen levels required for combustion, which in turn effects on the power Output that produced, This study conducted by a theoretical investigation to observed the effect of these factors on the hypothetical engine its power 100 kW .to finding the impact of temperatures by chosen among 10 to 48 C⁰ at sea level,  then make correction by added altitude at 100 meters, with 65% relative humidity and atmospheric pressure equal 98.8 kPa, then altitude of 800 meters with 50% relative humidity and atmospheric pressure 91 kPa, where observed decreases in that engine power Output with each increases in temperature and less of density were recorded approximately  7%, 11% and 17%, at 48 C⁰ respectively compared to its power output, under standard conditions.
