Gas and Petroleum Engines

_Early Lenoir engine_ (1860).—The motor (Fig. 1) resembled in external appearance a horizontal double-acting steam engine. This design was in great favour at that time, being co...

There is a great deal of difference, from an economic point of view, between spirit or carburetted air engines which we have just described and motors using ordinary commercial...

We have so far followed, step by step, the various improvements undergone by internal furnace engines, from their first practical realization thirty-seven years ago by M. Lenoir...

The history of gas engines may be said to date from a time when coal gas and petroleum were unknown. This statement appears at first somewhat paradoxical, but it arises from the...

Gas engines are in most cases mounted on a metal bed-plate, and for small engines the weight of the machine is very often sufficient to keep it in place; it is more satisfactory...

Assuming that the earth once formed part of the sun, the whole of the energy at our command for commercial purposes can be traced back to the sun as source. This energy we have...

If cold air be saturated with the vapour of volatile spirits such as gasoline, or distillates of petroleum of about ·65 mean specific gravity, an explosive mixture is formed wit...

_Simplex motor_ (Fig. 45).—Although this motor works equally well with coal gas and oil, we have put off the description of it until now because it has become associated particu...
