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%.
