Although a great triumph of technology, the convenience afforded by these vehicles comes at a cost, not only in fiscal terms, plainly also to the environment in which we live. The ever change magnitude number of cars, lorries buses etc. that be manufactured and driven throughout the world are causing long term pervert to the air we breathe as well as down valuable natural resources. Some of the main problems are discussed below.
oneness of the major issues regarding internal combustion engines regards the by-products of burning petroleum products in oxygen. These by-products are emitted from the engine exhaust systems and contain various undesirable chemicals. The quantity of these chemicals discharged depends on the engine fuel but does include oxides of nitrogen, sulphur and carbon, as well as soot, skulk particulates and heavy metals.
The oxides mentioned above affect the environment in a number of ways. Sulphur oxides, nitrogen oxides and carbon dioxide are fancy to contribute to the effect known as Global Warming.
These gases are known as ? babys room gases because the molecules tend to trap disturb energy within the earths atmosphere instead of letting it pass through into space, creating an effect like the inside of a greenhouse where the glass has a similar effect of trapping conflagrate energy. Road vehicles are by no means the beat polluters of these gases to the atmosphere but do contribute a real percentage to the total. In Europe in the 1970s, transport was amenable for 28% of nitrogen oxides (NOx)...
