Incidence of environmental effects on the behavior of the internal combustion engine in compression and air flow

Abstract

As more and more people use motor vehicles in different environmental conditions, it is necessary to study the performance of the engine under these conditions, which is done by using an oscilloscope to determine the behavior of each point on the waveform diagram to real tests. outdoors at less than 2500 meters above sea level. The vehicle was tested under standard environmental conditions, from sea level up to 300 m to 2500 m above sea level. Based on these tests, it was determined that altitude has a direct effect on its performance, since the compression value gradually decreases as the altitude increases, concluding that the cylinder pressure drops by 5%. Temperature also plays an important role in its effects. at the water inlet. The percentage correlation between flow and flow is 1°C for every 154 meters of elevation. Similarly, airflow at each test point was measured using a scanner built into the car to determine the effect of combined pressure and temperature changes on engine performance. It was found that intake pressure had a significant effect and engine performance was affected. Not operating properly in saturated or lean conditions due to pressure fluctuations in the intake manifold.
