Which of the following gases is emitted into the atmosphere as a result of fuel combustion in the engine?

Question

DentroTest · Accepted Answer

The correct answer is carbon dioxide (CO2). In an internal combustion engine, burning fuel (gasoline or diesel) generates various chemical residues that are expelled through the exhaust pipe. Carbon dioxide is one of the main products of this chemical reaction and is a greenhouse gas contributing to global warming. Analysis of the options:   Carbon dioxide: It is the direct product of burning hydrocarbons.   Methane and Natural Gas: These are not products of combustion; rather, they are fuels themselves (natural gas is primarily composed of methane).
