line engines. Now, we are trying to make them like Diesel 

 engines. So, with constantly better alloys and knowledge of 

 combustion, we are steadily taking metal, and noise, and smell 

 out of the Diesel." 



In 1937 Kettering declared that "the Diesel is entering new 

 fields of usefulness entirely unsuspected just a few short years 

 ago." Today the Diesel seems headed for still newer fields. 



Recently it was discovered that when ordinary gasoline was 

 used as a fuel in the Diesel it gave one-third more miles per 

 gallon than the same fuel would have given in a gasoline 

 engine. This discovery may lead to the adoption of a fuel- 

 injection gasoline engine, without spark plugs or carburetor, 

 which operates on the Diesel principle. Excellent German 

 aviation engines use the fuel-injection system and give plenty 

 of power with gasoline which has a much lower octane rating 

 than our new fuels. So here is another possibility for the super- 

 efficient postwar auto engine. 



Jeeps for the Farm 



When they stop to think about postwar cars, engineers give 

 some attention to the jeep's character and performance. This 

 2,200 pound combat car can carry six men in an emergency, 

 mount a fifty-caliber machine gun, and tow guns and other 

 equipment. There are few jobs in the Army that it hasn't 

 been asked to do and it does them well. 



It is powered by a four-cylinder, sixty-horsepower, go-devil 

 engine and has six speeds forward and two in reverse. It can 

 plow through high water, duck in and out of ditches, dodge 

 under trees, and scramble up steep hills while its crew is 

 pumping lead at the enemy. 



The American Bantam Car Company came forward with 

 an idea for a jeep in 1940, and the Army promptly dropped its 

 plan to buy a lot of motorcycles. Willys-Overland, Bantam,
