1. A range of nitrogen oxides (NOx), such as nitrous oxide and nitrogen dioxide, which will form nitric acid or nitrous acid that will contribute to acid rain. NOx is formed by reaction of nitrogen and oxygen in the air so is pretty much unavoidable. It can be reduced by decreasing the time that combustion occurs for and this is why aeroplane jet engines have become shorter in length over the years - a shorter combustion path through the engine will produce less NOx.
2. A range of sulphur oxides (SOx), which will form sulphuric or sulphurous acid that will also contribute to acid rain. SOx is formed by reaction of sulphur in the fuel with oxygen in the air and can be avoided by using low-sulphur fuels.
3. Carbon monoxide formed by partial combustion of fuel which is poisonous.
4. Soot, which is essentially small carbon particles that have been implicated in contributing to lung diseases as well as turning everything black.
5. Carbon dioxide formed by combustion of fuel that is a greenhouse gas.
6. Unburnt hydrocarbons which may also be greenhouse gases.
7. Polyaromatic hydrocarbons - very toxic.

The combustion of fossil fuels in an engine relies upon on the terrific gas to air ratio. inadequate air motives the production of Carbon Monoxide as nicely as Carbon Dioxide. jointly with this, the fuels additionally incorporate small quantities of sulphur compounds which, whilst burned, produce Sulphur Dioxide and different Sulphur componds. The Nitrogen of the air additionally reacts with the Oxygen and the fuels to offer Nitrogenous compounds. i've got faith that some manufacturers of fuels nonetheless upload Tetra-ethyl bring about strengthen anti-knock qualties of the fuels.. yet another nasty emission. All of those reactions pour those pollutants into the ambience. it is the quantity of 'Nasties' interior the air that motives envionmental issues. it is not merely motor vehicle engines yet, lots of the industries interior the international which comprise aviation, additionally use fossil fuels ..all upload to the topics. Many present day automobiles are equipped with 'Catalytic Converters' that help to cut back those emissions.

No2 (Acidic Rain)
Co (Carbon Monoxide)
So2(Acidic Rain)
Co2 (Greenhouse gas/effect)
The above answer is wrong, CO (carbon monoxide) does NOT cause greenhouse effects. It kills you as it stops oxygen getting to the brain. CO2 causes greenhouse effects.
More obviously, but this is the main ones.

1-carbon monoxide- global warming
2- sulphers- acid rain
