Reader Mr Jiang comes post says: Spring rainfall is increasing, drive to be met every time flyblown automobile body does not say, worse is wet drives to encounter expect to be less than the trouble that endangers a travel security even via regular meeting. Accordingly, hope expert introduces the characteristic that wet drives and common law.
The expert solves: Feng Yu day, the main factor that affects travel safety directly is visibility and road surface state two big hidden trouble.
Alleged visibility is the farthermost distance of the horizontal way that the naked eye that points to a person can see through air. Wet rainwater is aspersed fall, make windshield and rearview mirror punch-drunk, the radial reflex that adds damp road surface makes visibility is reduced greatly. The attrition that road surface state is affecting a wheel directly (adhere to) coefficient, affect the performance of apply the brake of the car thereby. Drive in dry road surface, speed rises, the adherent force between wheel and road surface did not change almost. And wet, go up in damp road when car travel, the catchs soil fertility to follow speed addition of the wheel and quick decrescent, very incidental " water slips " , right now, step on footplate of apply the brake not urgently or strike change direction dish.
Every Che Youdou has most propbably experience, issue wet, asperse when raindrop when falling on car pane, the line of sight of car ahead gets very quickly block up, car, pedestrian and scenery become punch-drunk. Right now, open rain is blown implement, car ahead is met a clarity. Accordingly, if wet drives car, do not use rain to blow implement or rain is blown implement if malfunction and cannot working normally, very adverse to safety of drive a vehicle. So car advocate before heavy rain, should check car rain to blow implement whether can work normally. What nevertheless need makes clear is: Rainstorm day, dot of quickness heavy rain is hit on windshield, although rain is blown implement movement is again rapid, blow clean raindrop hard also, the line of sight that causes a driver is affected, to ensure drive a vehicle is safe, should stop instantly sail.
"Electronic-controlled high pressure in all course " how be to return a responsibility?
Incoming letter of reader Mr Hou asks: With a ha not allegedly (quote; picture) oil of derv edition province is with " electronic-controlled high pressure in all course " about, excuse me " electronic-controlled high pressure in all course " what technology be?
The expert solves: "Electronic-controlled " it is to show fuel injection system is controlled by computer, ECU (common weighs computer) to the fuel injection of every atomizer hour of quantity, fuel injection undertakes be controllinged accurately, can make the fuel economy of diesel engine and dynamical sex achieve first-rate balance, and traditional diesel engine is control by machinery, control precision cannot be able to ensure.
