Introduction A hybrid car is a car used to drive the drive wheels more than one source of energy. Modern car manufacturers often resort to sharing of the internal combustion engine and an electric motor, which avoids the mode of the internal combustion engine in low loads, and also to realize the recovery of kinetic energy, increasing the fuel efficiency of the power plant. Another common type of hybrids is vehicles, in which ICE is combined with engines running on compressed air.

It should be distinguished from hybrids vehicles with electro-mechanical transmission, such as locomotives, some tractors and tanks.

Introduction.

A combustion engine can be defined as any engine that operates through fuel burning. The difference between a combustion engine and steam engine is that the latter uses steam for operation while the former uses gasoline. Combustion engines also use fueled gases such as hydrogen, propane, methane etc which are components of diesel. Combustion engines run on one type of fuel, and may require a series of adaptation to adjust to fuel/air ratio to use other forms of energy (Agrawal, 2006). The combustion process starts in the gasoline cylinder where a mixture of air and gasoline is sprayed. The mixture is ...

Today there are two different headlines over the news that seem to give opposite information. One common headline tells us that peak oil has been reached and oil is not going to last forever. The story under the headline usually gives information about living a more environmentally sustainable lifestyle by switching to alternative fuels. On the other hand, there are other headlines declaring that there is plenty of oil because petroleum companies are taking advantage of deep sea drilling and sand tars. Our science courses tell us that there is only so much fossil fuel because the amount depends upon ...

Greenhouse Gas Emissions and two methods of reducing these emissions

Greenhouse gas emissions are a rising concern facing the entire world today. Greenhouse gasses are essentially those chemical compounds found on earth which allow the passage of sunlight into the earth’s atmosphere. When the sun shines down upon the earth it emits light that penetrates into the Earth’s surface, however some of this light is reflected back into the space in the form of heat or infrared radiation. It is this radiation that is absorbed by the green house gasses and retained within the atmosphere. Greenhouse gases are necessary to maintain the atmospheric temperature on earth. According to ...
