1 1-2 H. P. Hopper- Cooled National Engine 



General Description 



In design National Engines have all the strength needed to withstand continuous hard 

 work. Every working strain is properly provided for. 



The Cylinder is made of semi-steel, noted for its remarkable strength and density. Every 

 hopper cooled cylinder is given a special high pressure water test to guard against leaks in the 

 cylinder walls or jack ~t. The water space is exceptionally wide and a drain at the bottom of 

 the cylinder allows wai^r to be taken out when necessary. 



The Crank Shaft is a steel drop forging of the best quality, accurately finished by grinding. 



The Connecting Rod is of malleable iron and has an automatic lubricating method. This 

 takes care of the bearings on both ends froin the waste cylinder oil — a saving of expense and 

 trouble. 



The Piston is ground to a mirror finish and has automatic lubrication for the wrist pin 

 bearing. 



The Piston Rings, three in number, are eccentric and lap jointed. This is the most perfect 

 ring known. They are ground like the piston. 



The Governor is of simplest design, hit and miss, absolutely reliable and economical in its 

 regulation of fuel consumption according to load. 



The Fly Wheels — Smooth running in an engine, esjiecially on truck, depends on the fly 

 wheels. National Engines have fly wheels that are accurately turned and properly balanced. 

 The engines will run steady without blocking the truck wheels. 



The Mixer is our famous design with both needle valve and air shutter regulation. These 

 adjustments enable the user to secure uniform results under varying loads. 



Lubrication is ample throughout — a sight feed oiler on the cylinder and automatic lubrica- 

 tion on the connecting rod. The crank bearings have hard oilers. 



Ignition is either make and break or jump spark. Each kind ij of the simjilest character 

 and perfect in adjustment when the engine leaves the factory. 



National Engines are shipped ready to i-un after careful tests at the factory. Unless dam- 

 aged in transit the engine will be ready for work as soon as uncrated and sujijilied with fuel 

 and lubricating oil.
