The steady increase in the size of oil engines is shown by the fact that Messrs. Richard Hornsby and Sons, of Grantham, are about to exhibit at the Royal Agricultural Society's Show, which opens to-morrow at Chester, an engine of 16 brake horse - power. The general appearance is shown by the illustration above. We have on more than one occasion described the construction of these engines, but we may recall that they are differentiated from those of other makers by the fact that there is no separate vaporiser and no ignition tube. The oil is injected directly into the combustion chamber, and is immediately flashed into vapour, exploding spontaneously when the compression attains its maximum. The result is that great simplicity of construction is attained. The governor reduces the supply of oil, as the demand for power falls off, but does not cut it off completely, as in the hit-and-miss arrangements. More regular turning is thus secured.
These engines are now constructed from 14 up to 25 brake horse-power, as single cylinder engines, and up to 50 horse-power, with two cylinders. They will run with oil varying from a specific gravity of .8 to .880. |
