what is the smoke from a car made up of?

Question

just the main ones plz

Answer 1

The two main portions are CO2 and water vapor in roughly equal proportions.

This will also depend on the state of tune of the engine and additives or other trace elements in the gasoline. Carbon dioxide is the waste gas (along with water vapor) formed when a hydrocarbon fuel burns with enough oxygen. For example, a less efficient engine will be putting out less CO2 and leaving a combination of carbon monoxide, free carbon (soot), and unburned fuel - water vapor would still be the same, and there would still be more CO2 than the other carbon waste products, just less than in a "clean" burning engine.

In the real world, you can never get that perfect or complete combustion, so there will always be some of the other gases. Similarly, since there is more nitrogen in the air than any other gas, some of the nitrogen can enter the combustion to form different toxic products, mostly NO2. Oxygen can also form ozone (O3) which is irritating to humans down low, but is beneficial when it is high up in the atmosphere.

Answer 2

The smoke in car is a hodge podge of nitrogen oxides, sulfur oxides, incompletely combusted fuel and any residual organic substances that was not filtered nor completely combusted. Depending upon the amount of each the smoke appearance varies.

Answer 3

The main thing is CO2 of gasoline and oil. Then the other is CO of both and the CO is the bad stuff.

Answer 4

Carbon Monoxide. Toxic to most living things.

Answer 5

If your car smokes, you need to get it fixed.

Answer 6

carbonmonoxide, in the main!

Answer 7

carbon dioxide
