Car engines and its efficiency is the most talked about thing in the present times. The debate on the same is till on, which needs a clear and beneficial conclusion. Whatever it is, the main thing that concerns most of the people is how efficient the engine of their car is. Frankly speaking, it does not matter at all to a layman, he just wants better efficiency but is he getting it.
According to a survey, it has been that efficiency of the car engines ranges form 20 percent to 80 percent and in most of the lies around 20 percent only. So, in short your 80 percent of the energy that you feel is giving energy to the car engine parts is actually a total wastage.
The thermodynamics law is the culprit behind this wastage of energy. A large amount of heat is needed to form a difference between the upper operating and the lower operating temperatures of the car engine. The heat thus produced do not contribute to the movement of the car and hence a total wastage.
But what could be the possible solution of this. Water, which is abundant in large amount is the one best suited for the purpose. Water molecules can easily provide the energy required to maintain the regional difference of the temperature, which eventually would help car engines to extract better efficiency from the same fuel. A simple calculation would automatically tell you how much you will save on your fuel related expenses.
