Franklin was the undisputed leader in air-cooled cars at a time when virtually every other manufacturer had adopted water cooling as cheaper and easier to manufacture. Before the invention of antifreeze , the air-cooled car had a huge advantage in cold weather, and Franklins were popular among people such as doctors, who needed an all-weather ...
Franklin O-335. The firm began as the H. H. Franklin Co. in 1902 in Syracuse, New York, US, to produce Franklin air-cooled automobiles.Barely surviving bankruptcy in 1933, the company was purchased by a group of ex-employees and renamed Air-cooled Motors in 1937.
An air-cooled flat-6 engine, the Franklin O-335 made by Air Cooled Motors (and originally intended for the Bell 47), [22] fit, and its 166 hp (124 kW; 168 PS) pleased Tucker. He purchased four samples for $5,000 each, and his engineers converted the 334 cubic inches (5,470 cc) engine to water cooling (a decision that has puzzled historians ever ...
John Wilkinson (February 11, 1868 – June 25, 1951) was born in Syracuse, New York.He invented the air-cooled motor which was used in the Franklin (automobile) produced by H. H. Franklin Manufacturing Company where he was chief engineer and designer from 1902 to 1924.
1945–1975 Franklin O-335 air-cooled aircraft engine Early flat-six engines include the Franklin O-265 which began production in 1940, and the Lycoming O-435 which began production in 1942. Several manufacturers use the letter O in their model codes for flat-layout engines as a designation for “opposed” cylinder layouts.
The T7 armored car was a prototype small armored car produced by Holabird Quartermaster Depot for the US Army in 1930. All six vehicles that were completed, USA W1310, USA W1311, USA W1312, USA W1313, USA W1314 and USA W1315, were 4x6 wheeled vehicles, powered by Franklin's air-cooled, 6-cylinder, gasoline engine, with a crew of four and armed with one .50 calibre machine gun supported by two ...
In the United States, Franklin built air-cooled engines. For many years air cooling was favored for military applications as liquid cooling systems are more vulnerable to damage by shrapnel. The Czech Republic–based company Tatra is known for their large displacement air-cooled V8 car engines; Tatra engineer Julius Mackerle published a book ...
Air-cooled engines rely on the circulation of air directly over heat dissipation fins or hot areas of the engine to cool them in order to keep the engine within operating temperatures. Air-cooled designs are far simpler than their liquid-cooled counterparts, which require a separate radiator , coolant reservoir, piping and pumps.
