Pollution-causes and effects

Result of inefficient combustion:

Cause	Product	Results in	Effect
Cold engine/excess unburned fuel	Hydrocarbons(HC)	Unburned fuel vapor	It is often related to problems into the ignition sytem. Reduced engine performance
Cold engine/excess unburned fuel	Carbon monoxide(CO)	Partially burned fuel	Toxic gases:health problems
Excessive temperature	Nitrous oxides(NOx)	Nitrogen-oxygen mixture	Combines with vapor in atmosphere to produce acid rain
