Lè machin nan itilize, motè a jenere twòp chalè. Yo nan lòd yo fè motè a pa travay byen akòz surchof, se yon sistèm refwadisman sikilasyon likid ki fèt, nan ki fanatik la refwadisman jwe yon wòl esansyèl. Pou fanatik la refwadisman kontwole elektwonikman, metòd kontwòl yo itilize pa diferan modèl yo diferan. Sa ki anba la a se yon konbinezon de de egzanp fòt yo konprann prensip la k ap travay ak depanaj nan de metòd yo komen kontwòl fanatik elektwonik.
Example 1 A car with a displacement of V62.4L, the cooling system of the car is "opened" because the electronic fan does not turn, and the electronic fan still cannot run when the air conditioner is turned on. The control of the radiator fan of this Audi car is realized by controlling the ground wire of the fan relay through the dual temperature thermal switch. There are two electronic fans in the cooling fan system of the car. The red wire in their connection harness is the positive wire, the brown wire is the ground wire (directly fixed on the beam), and the red positive wire is a positive wire on the right beam. fixed at the column.
The control of the red positive line is divided into fan low-speed relay, air-conditioning relay and fan high-speed relay control. Pay attention to their specific positions during maintenance. The fan low-speed relay is located in the third relay position in the fuse box on the right side of the engine, and the fan high-speed relay is installed in the No. 217 relay in the auxiliary fuse box under the driver's feet. The low and high speed of the fan The operation is realized by the dual temperature thermal switch on the radiator, which controls the grounding of the relay according to the temperature of the coolant.
Lè switch la èkondisyone vire sou, se relè fanatik la ba vitès kontwole pa relè a fanatik èkondisyone fè fanatik la refwadisman Thorne. Fil tè a (vèt/jòn fil) nan relè nimewo 217 la konekte ak switch tèmik doub tanperati a. Yon fwa tanperati awozaj la monte nan yon sèten tanperati, switch tèmik doub tanperati a kontwole relè a sou tè a, ak fanatik refwadisman an pral antre nan yon eta operasyon gwo -vitès. Anplis de sa, fil prensipal la ap viv ak kontwòl fil kouran nan nimewo 217 relè yo tout kase lè switch ignisyon an vire sou?
According to the working principle of the cooling fan system of the car, it is found that the car lacks a fan low-speed relay (the user reported that the car has been repaired in other repair shops). But after it is installed, the cooling fan has only high-speed gear and no low-speed gear. After careful inspection, it was found that the No. 217 relay was burned, causing the cooling fan to always run at a high speed. After the No. 217 relay was replaced, the fault disappeared. Example 2 In a Samsung Jielong car, the water temperature gauge shows normal temperature during driving, but if the engine is stopped and the engine is running at idle speed, although the water temperature gauge shows between 90-100 degree , the cooling system has been "opened" at this time. At this time, it was found that the cooling fan could not operate at all. The control method of the cooling fan of this car is very different from that of the Audi car. This Samsung Jielong car cooling fan is controlled by the car computer. After inspection, the cooling fan relay lacks the control ground wire. When the engine is running at idle speed, the actual temperature of the coolant is measured with a thermometer and has reached 110 degree , but the water temperature gauge of the car still indicates between 90-100 degree . Using a multimeter to measure the resistance of the water temperature sensing plug is about 100 ohms. Therefore, it is initially suspected that the water temperature sensing plug is damaged.
Nan absans pyès ranplasman, jwenn yon rezistans varyab glisman 2k ohm an paralèl ak ploge deteksyon tanperati dlo a pou diminye valè rezistans lan. Si rezistans varyab glisman an ajiste nan moman sa a pou tanperati a parèt nan kalib tanperati dlo a ki konsistan avèk tanperati aktyèl la nan awozaj la, fanatik refwadisman an aktyèlman opere nòmalman ak ogmantasyon nan tanperati.
Li parèt ke kòz la nan fonksyone byen se ploge nan Capteur tanperati dlo. Paske ploge deteksyon tanperati dlo a domaje, li toujou bay òdinatè machin nan yon siyal erè tanperati ki ba ke fanatik refwadisman an pa ka opere. Natirèlman, fanatik refwadisman an pa ka opere nòmalman. Finalman, apre yo fin ranplase ploge deteksyon tanperati dlo a, machin nan tounen nan nòmal.
Li ka wè ke òdinatè a nan machin sa a resevwa siyal la opinyon nan ploge nan Capteur tanperati dlo a, epi lè tanperati dlo a rive nan valè a espesifye, òdinatè a kontwole fil la tè nan relè a fanatik nan tè fè fanatik la refwadisman kouri. Pi wo a se de metòd kontwòl konplètman diferan, men osi lontan ke nou kalkile prensip k ap travay yo ak fè enspeksyon ak anpil atansyon analiz nan fay la, pwoblèm nan nan zòn sa a kapab tou byen vit rezoud.
