![]() What’s more, as the air flow increases, more fuel can be delivered to the engine. In this situation, the controller must provide it with more electricity. If, therefore, its temperature drops quite significantly, this indicates an excessive amount of flowing air. The purpose of the mechanism is to maintain a relatively constant wire temperature. The air flow causes the wire temperature to drop in proportion to its quantity. During operation, it heats up to about 100 ° C, which is a starting point for reading data later. And it is thanks to this that the flowmeter becomes only a measuring element over time, which transmits the information received by means of electrical impulses.Ĭurrently, the sucked air flows smoothly around the thin wire found in the device. The development of technology and electronics, as you can guess, favors new designs. However, this solution was not very effective and often failed. It affects, among others on engine speed or complete combustion while driving.įormerly, the functioning of the element was based on a flap with a lever assembly and an injection pressure regulator in the air duct. This is an extremely important function in the face of the proper functioning of the drive unit. The air flowmeter transmits the information obtained to the engine control unit, while this one can properly correct the condition of the mixture so that the optimal values are maintained.
