Answer
The complete combustion of diesel oil produces carbon dioxide (CO₂) and water (H₂O) as primary products.
Carbon dioxide is a greenhouse gas that traps heat in the atmosphere, contributing to the greenhouse effect. As the concentration of carbon dioxide increases due to combustion processes, it enhances the natural greenhouse effect, leading to global warming and climate change.
