Impact of the Solar Ventilation System on the Fuel Savings and CO2 Reductions for Gasoline Vehicle Engine Parked Under the Sun

Abstract

In summer, greenhouse effect impacts on both of the passengers and car itself, due to high temperature inside the car cabin while it is parking under blazing sun; which oblige them to turn on the air conditioner, which is considered the greatest single secondary load on a car engine due to energy consumption. Therefore, This paper describes the experimental investigations conducted on a parked car equipped with a solar-powered ventilation system, as well as highlights and clarifies its impacts on climate control, energy consumption, and tailpipe emissions of a conventional gasoline engine operating at idle. Since this experiment was applied in two stages; the first stage was without solar ventilation and the findings showed that the highest interior cabin temperature was 65.5 °C and the average daily difference in temperature was 19.2 °C. The second stage with solar ventilation and the findings showed that the highest interior cabin temperature was 48.5 °C and the average daily difference in temperature was 8.5 °C. On the other hand the experimental results referring to fuel consumptions and CO2 emissions showed that due to using of the solar ventilation system the reduction in fuel consumption by 38% and the CO2 emissions reduction by 36%.
