Sinopsis

Excerpt from Diesel: The Modern Power

Early in history men began to think of mechanical means of obtaining power. It is related that in 130 rc. Hero built the first steam engine. However, over nine teen centuries were to pass before James Watt made the steam engine a practical means of doing work. From Watt's time on, the develop ment of the steam engine and its utilization were extremely rapid. On rails, on water, and in industry it was almost supreme for a hundred years. Steam engines are at their best when large units are needed. But they are still not as efficient as internal combustion engines. Portable steam plants are difficult to build small enough for uses where weight and space are factors.

Excerpt from Diesel: The Modern Power
Compression ratio is an engineer ing term which is really quite simple. If we say an engine has a compression ratio of 6 to 1, it means that the volume above the piston is six times as much when the piston is at the bottom of its stroke as it is when the piston is at the top. If the cylinder in the first two illustrations would hold six pints with the piston at the bottom of the cylinder, and one pint with the piston at the top of the cylinder, it would have a 6 to 1 compression ratio. Likewise, if the capacity was sixteen pints at the bottom and one pint at the top, as in the second two illustrations, the compression ratio would be 16 to 1. These two compression ratios, 6 to 1 and 16 to 1, are typical of those for a gasoline engine and Diesel engine respectively.
This means that if the cylinder is full of air or a mixture of gas oline and air when the piston is at the bottom of the stroke, it is squeezed to one-sixth of its volume in the gasoline engine and to one sixteenth of its volume in the Diesel engine when the piston reaches the top of the stroke.
