A throttle body schematic is a visual representative diagram of the parts involved in the throttle body of a vehicle. The throttle body is the part of the air intake system of a vehicle that allows specific amounts of air into the engine. A schematic for the throttle body is a drawing that displays the layout of the entire system.
The combustion of an engine relies on the engine maintaining the correct ratios of oxygen to fuel. For an engine to run efficiently and effectively, it needs both an air-intake system to bring in outside air, as well as a fuel pump to pump in gas from the gas tank. There are a number of parts in the air-intake system, one of which is called the "throttle body." The throttle body has a valve that opens or closes, which regulated the amount of air that is being put into the engine.
A schematic is a type of technical drawing that displays the parts of a piece of equipment. In this case, a throttle body schematic would display all parts of the throttle body in the correct placement, such as the valve, the chamber, the various seals and the moving parts. A schematic helps individuals to understand how the throttle body is put together, both mechanically and electronically.
