Majority of the automobiles run on fuels like petrol or diesel. Emissions from these automobiles contribute directly towards air pollution.

Also the type and amount of pollution from automobiles depends on factors like:

Type of engine or vehicle (e.g., passenger car, heavy-duty truck, lawn mower, locomotive, etc.)
Type of fuel used (e.g., gasoline, diesel, or alternative fuels)
Type and condition of emission control devices (e.g., catalytic converters) and
How the engine is used/run.

Common pollutants that are produced by automobiles on the combustion of fuels are:

Hydrocarbons (HC)
Carbon Monoxide (CO)
Oxides of Nitrogen (NO_x)
Particulate Matter (PM)
Sulphur Dioxide (SO₂)
Carbon Dioxide (CO₂)
Nitrous Oxide (N₂O)
Toxins
