Air pollution today is a serious problem because the entire ecosystem is destroyed. It is important to make sure that the vehicles with internal combustion dissolve glaciers at the very far end of the world, just as the noise of the motor vehicle and the rolling of the wheels on the roads hampers the normal functioning of other people on a daily basis. An increased noise level directly affects the quality of life, especially in urban areas due to densely populated areas near the roads. Hazardous emissions of discharged gases from the vehicle are the product of development of all branches of transport, including greenhouse gases and substances that destroy and destroy the ozone layer. This is the result of sulfur and nitrogen oxide emissions that are increasingly endangering human health. The world's automotive industry is hastily upgrading the drive groups to alternative fuels because the traffic must work even when one day the oil sources are completely overwhelmed, and in this paper are explored and described alternative fuels in transport that would greatly assist in preserving the ecosystem.
