The sensor of amount, electronically controlled gasoline injectionEngineIn order to which the mixing of optium concentration can be obtained under various Operation Conditions
Gas, it is necessary to which correctly measure is every sucks in a flashEngineAir capacity, in this, asECUCalculate (control）Distributive value it is main
Foundation.If air flow sensor or circuit break down,ECUIt cannot get correct air inflow signal, it cannot be normally
The control of distributive value is carried out, gaseous mixture overrich or excessively dilute will be caused, madeEngineIt operates abnormal.Electronically controlled gasoline injection system
Pattern that there are many air flow sensor of system, common air flow sensor can be divided into blade by its structural shape（Wing plate）
Formula, amount core type, hot-wire, hot diaphragm type, toll bar vortex etc. are several, on Injection Turbo, measure engine
The sensor of the air capacity of institute's inspiration, i.e. air flow sensor are one of important components of decision systems control accuracy, still
In actual use, air flow sensor lacks effective air filtration mode in use, secondly be also not easy into
The stabilization of row installation, these are all physical presence urgent problems again.
