National Oil Engines 



Operate on Nearly All of the Lower Grades of Oils 



When buying an oil engine look carefully into the plan of ignition. 



Successful and economical operation depends upon the ability of the 

 engine to convert all of the fuel entering the cylinder into power. 



It stands to reason that an igniter that extends into instead of out 

 from the cylinder, thereby preventing the radiation and loss of power 

 giving heat units, will be the most economical. 



The Internal Igniter (patent applied for) is a distinctive feature of 

 the NATIONAL. (See cut.) 



It is far superior to the usual type of external hot ball because: 



It conserves the heat units, turning them into power. 



It maintains a more even temperature. 



It is easier to heat in starting. 



It enables the engine to be run successfully under a greater vari- 

 ation of load. 



IT IS ABSOLUTELY SAFE. 



The external hot ball becomes brittle and frequently explodes. 

 The NATIONAL INTERNAL IGNITER can not explode as it is 

 subjected to a compressing instead of an expanding strain. 



Reduce the expense and increase the efficiency of your power plant 

 by installing a NATIONAL.
