Why All the Great Engines Must 

 Pattern After the Hot Spot Chalmers 



THOSE of you who would like, 

 every now and then, to break 

 into a dozen pieces the engine of 

 your car with a sledge-hammer— or give 

 the car away —or those of you who send 

 it too often to the repair shop — stop a 

 moment and ponder over this: 



Maybe it isn't the engine's fault, nor 

 yours, for that matter. Nine chances in 

 ten it's the kind of gas you're using. 

 For gas has gone down and down in grade. 

 Chalmers engineers were quick to 

 note the _ change coming, and they 

 worked night and day and were first to 

 furnish the remedy— a rede- 

 signed engine. 



The inferior gas of the day 

 is heavy. It's so heavy that 

 even after leaving the carbu- 

 retor it still is in more or less a 

 raw condition. 



So the Chalmers engineers 

 figured they must "crack up" Quality 



the gas finer, which they have accom- 

 plished by that wonderful device known 

 as Hot Spot. 



This process done, the task then 

 was to pass the gas into the cylinders 

 with lightning-like rapidity so that the 

 gas couldn't condense. 



To accomplish this the Ram's-horn 

 Manifold was designed. It takes its 

 name' from its shape. It has no sharp 

 corners to block the rush of gas, but 

 instead "easy air bends." 



Hence no ' c pools"collect and the gas is 

 passed to each cylinder in the same quan- 

 tity of mixture at the same time. 

 Sooner or later other cars 

 will come to these Chalmers 

 principles. It is as certain as 

 the sun will rise tomorrow. 



In the meantime Chalmers 

 sales are climbing to rare new 

 heights. Price, five-passenger,
