The Daimler Oil Motor

We illustrate a very ingenious and interesting form of oil engine, designed by Mr Daimler, for many years associated with the late Dr Otto.

It is made in various forms for ordinary fixed motor purposes, for fire engines, for tramways, for light carriages and quadricycles, and very numerously for launches and pinnaces…

…The engines work with the lighter oils or rectified petroleum, called motor benzine or petrol, which has a specific gravity of from 0.68 to 0.7.

The principle on which all the forms of the engine work is the same. The engine is completely encased in a cast iron crank chamber, which contains, in the form shown in our detail engravings, four vertical and parallel cylinders.

The pistons in these are provided with three cast iron rings, and the connecting rods are attached to the piston direct, and to the four cranks of a cast steel shaft.
