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



General Description 



In design National Engines have all 

 the strength needed to withstand con- 

 tinuous hard work. Evei-y 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 jacket. The water space is 

 exceptionally wide and a drain at the 

 bottom of the cylinder allows water to 

 be taken out when necessary. 



The Crank Shaft is a steel drop 

 forging of the best quality, accurately 

 fini.slied by grinding. 



The Connecting Rod is of malleable 

 iron and has an automatic lubricating 

 metliod. This takes care of the bearings 

 on both ends from 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 

 ecom^mical in its regulation of fuel 

 cons\imption according to load. 



The Fly Wheels — Smooth running in 

 an engine, especially on truck, depends 



Engines 

 accurately 



on the fly wheels. National 

 have fly wheels that are 

 turned and properly balanced. The en- 

 gines will run steady without blocking 

 the truck wheels. 



The Mixer is our famous design with 

 both needle valve and air shutter reg- 

 ulation. These adjustments enable the 

 user to secure uniform results under 

 varying loads. 



Lubrication is ample throughout — a 

 sight feed oiler on the cylinder and 

 lubrication on the connecting 

 crank bearings have hard

 Ignition 



is either make and break or 

 jump spai'k. Each kind is of the simp- 

 lest character and perfect in adjustment 

 when the engine leaves the factory. 



National Engines are shipped ready 

 to run after careful tests at the fac- 

 tory. Unless damaged in transit the 

 engine will be i-eady for work as soon 

 as uncrated and supplied with fuel and 

 lubricating oil.
