By generating chemicals in the engine and exhausting them straight into the atmosphere.
The fuel is in two parts: hydrogen and carbon from the gasoline, which is a hydrocarbon fuel, and oxygen that comes in through the air filter. Nitrogen also comes in and that also has an effect.
The pollution is mainly in the form of the greenhouse gas carbon dioxide, CO2. Gases possess mass just like liquids and solids do, and in a car engine the major reaction that produces heat energy is that for 1 kg of fuel we have 840 gm of carbon plus 160 gm of hydrogen combining with 3520 gm of oxygen to give 3080 gm of CO2 and 1440 gm of water. These reactions also produce 12.2 million calories of heat. The above figures are derived assuming heptane fuel which is a good approximation. A rough rule of thumb is that burning 1 kg of fuel produces 3 kg of CO2; or burning 1 pound of fuel produces 3 pounds of CO2.
Other minor reactions produce carbon monoxide from imperfect combustion, and nitrogen oxides from the action of heat on the nitrogen in the cylinder.

What are two things that pollute the air?
Cars and gas pollute the air.
Do electric cars pollute?

How do cars affect health and polution?
Cars pollute the air.
Do cars pollute the air when driving?
Yes
What does cars do to the environment?
They pollute the air by putting exhaust in the air.
Why are solar energy cars better than normal cars?
they don't pollute the air
What is the reason you have air pollution?
ANSWER:: Humans are responsible for 99% of all air pollution on the planet.
How do humans pollute?
We pollute by driving cars, smoking, burning trash, all and any smoke from schools, factories and building pollute our air. Many other factors contribute also.
Why is the air less pollution in antarctica?
The air in Antarctica is less poluted because there arn't cities and cars and things that pollute the air.
How often do you pollute the air every minute?
You can pollute the air from boats, planes, trains and also cars. All give off exhaust which people breath in and then can be diagnosed with major sicknesses/illnesses.
Do cars effect the environment?
Yes. Cars let out exhaust, which are gases from the car, that pollute the air! Some cars are electric or hybrid and cause little to no pollution.
How are cars harmful?
cars pollute the earth
