The air throttle valve is one of typical component of each car engine. Its principal function is to supply an appropriate amount of air to the engine. To be more precise, its function is proper or specific air dosing. Air is doses by using a special flap in the throttle. Its function is to open or close the main throttle nozzle or throat. When the flap is placed vertically, it ensures unrestricted flow of some amount of air, thus increasing car speed. Closing the throttle flap reduces the speed. The flap is controlled by the accelerator pedal.
Air Throttle Valve
Depending on specific solution used, there may be a throttle controlled with linkage or electronically. These system were implemented in manufacture and are used successfully since 1986. The implementation and use of an electronic throttle control system perfectly replaces the mechanical linkage. The linkage is placed between the accelerator pedal and the throttle centreline, thus enabling the vehicle to be speed up or down. At the simplest, just thanks to throttle flaps it is possible to control vehicle speed. At this point it should be noted that the electronic system increases driving comfort. Its primary function is effective control of engine power. The use of electronic control for this component allows also exhaust emission reduction.
Improperly working throttle may cause rough engine idling and increased fuel consumption. It may also cause poor acceleration performance when overtaking another vehicle, thus affecting safety of driving people.
