Engine Fuel Tank
The fuel tank on the Briggs and Stratton engine is a hollow metal container that houses the liquid fuel for use by the engine. The fuel tank must serve a myriad of purposes including:
-Providing the engine with a constant, steady fuel source (provided in our case by a pump extending from the carburetor).
-Venting to prevent extremely high pressure from accumulating. This must be done in conjunction with providing a leak-free storage environment for the fuel.
-Filling the tank with fuel.
How it works
The fuel tank is a relatively self explanatory part of the Briggs and Stratton engine. It is mounted beneath the carburetor, and a pump stemming from the carburetor that extracts fuel extends into the fuel tank. A fuel cap located on one of the upper corners of the tank covers up the hole through which more fuel can be added. The cap contains several valves that relieve excess pressure, often the result of a build-up of gasoline vapors. The pump from the carburetor is controlled exclusively by the carburetor and, although located within the realm of the fuel tank, is not directly controlled by the fuel tank. The gas tank is mounted to the engine via a bracket that attaches to the outside of the engine block.
1860- The first gas-fired internal combustion engine meant for large-scale production is invented by John Joseph Etienne Lenoir. The coal fuel used to run the engine is stored in a rubber bladder.
1909- The Ford Model T, one of the first mass-produced automobiles, implements a 10 gallon fuel tank that is mounted to the chassis behind the front seat.
1956- Packard introduces the first automobile with central power locking. Today, most automobiles' central locking controls the filler flap, a metal piece which covers the fuel tank in automobiles.
1990- General Motors faces a lawsuit regarding its decision to place the fuel tanks on many pickup trucks outside of the frame. This so-called side saddle design results in a $100 million fine.
1990's- Buell Motorcycle Company and several less notable motorcycle manufacturers begin constructing sport bikes that implement a fuel tank in which the fuel is dispersed throughout the frame of the bike in order to better distribute weight and give the motorcycle more stability by lowering the center of mass.
