ياباشا هاشوف اللينك .....بس صدقني انا متاكد من النظرية لانها حصلت معايا من اكتر من 6 سنين .....وماكنتش مصدق ان الكلام ده يحصل من شركة عريقة زي البي ام .....وبناء عليه عملت بحث جامد عن الموضوع ده واتاكدت من صحة المعلومة فعلا.....هي النقطة ان المعلومة في حد ذاتها مش مفيدة .....المفيد ان الواحد مايستناش لغاية ماخراطيم الميه تجيب اخرها.
طيب ماتعمل بحث تانىاقتباس:
وبناء عليه عملت بحث جامد عن الموضوع ده واتاكدت من صحة المعلومة فعلا
وورينا
أزاى ممكن الميه تروح من المكنه والحراره ثابته على المؤشر
إلا إذا كان فيه مشكله فنيه فى دايرة القياس
1- عداد بايظ مثلا
2- صباع بايظ مثلا
3- وجود خلل كهربى فى فيش التوصيل للعداد أو الصباع
أو وجود فتح كهربى فى خط نقل التيار بين الصباع والمؤشر
يعنى ممكن تكون شوفت كده فعلا
بس فيه عندك عيب فنى فى دايرة القياس
بس ميكونش ده الصح هندسيا
لأنه غير منطقى بكل المقاييس
علشان تعرف مدى تأثر مقاومة الصباع مع أى رفع مفاجىء أو متدرج لحرارة المكنهاقتباس:
بس ايه علاقته بالنقطة الي بنتكلم فيها!
وطبعا ده بينعكس على قراءة مؤشر الحراره
دا لو كانت دايرة القياس بمكوناتها سليمه فنيا
ياهندسة الحاجات البسيطة دي الحمد لله ماتعديش عليا....مش غرور والله.....بس لك ان تتخيل شنطة العربية عندي قارفاني أزاي من كتر ماحاطط فيها عدة وكل مانظمها امد ايدي تاني في حاجة وانعكشها:_Alshmokh08[1]: الحل اني ابطل الهواية دي خالص!!......ده غير ديجيتال افوميتر اساسي معايا ديما
هانعكش في مواضيعي القديمة وهارد عليك
ده اثبات في السريع كده ياهندسة واضح ضمن مضمون الكلام........ لغاية ماجيب حاجة اوضح..........ولاحظ الفرق بين السيارات المبردة بالهواء والي بالماء وهو ده فكرة السينسور المعدل الي بيتكلموا عليه

[flash=http://www.enginesaver.com.au/]WIDTH=350 HEIGHT=400[/flash]Engine Saver® - Low Coolant
Alarms
What is an Engine Saver® and why should I fit one?
An Engine Saver® is a device which monitors the coolant level in an engine.
Low coolant alarms are fitted to very few engines as standard equipment by manufacturers.
When the coolant level drops due to a split hose, a stone through the radiator, a faulty pump seal
or simply because the radiator cap wasn't replaced properly this device is designed to help warn you
Before any engine damage is done.
Over 70% of major engine blow-ups are caused by coolant loss going un-detected.
In fact the normal temperature gauge will drop in cases of sudden coolant loss as the sensor in
the cylinder head needs coolant around it to work properly.

طيب حوللى لينك القصه دى الأول علشان أربع وأقرأ براحتى
بدل اللوحه اللى أنت عاملهالى بالمربع الصغير
علشان أعرف أطلع كويس على الكلام
لأن واضح أن فيه تركات جديده فى دواير التبريد
بس مش موجوده فى عربيات الغلابه

what is an engine saver® and why should i fit one?
an engine saver® is a device which monitors the coolant level in an engine.
low coolant alarms are fitted to very few engines as standard equipment by manufacturers.
when the coolant level drops due to a split hose, a stone through the radiator, a faulty pump seal
or simply because the radiator cap wasn't replaced properly this device is designed to help warn you
before any engine damage is done.
over 70% of major engine blow-ups are caused by coolant loss going un-detected.
in fact the normal temperature gauge will drop in cases of sudden coolant loss as the sensor in
the cylinder head needs coolant around it to work properly.
when a heater or radiator hose splits or blows the coolant is suddenly lost in a matter of seconds.
the temperature gauge reading drops, the engine overheats and expensive damage is done.
when a stone or rock damages the radiator core coolant is lost.
if you are lucky the temperature gauge will rise and you may notice it in time.
if you miss it or the coolant is lost rapidly, preventing the gauge from working, goodbye engine.
if the vehicle is parked shortly after the hit, the coolant will seep out under the car.
some time later the driver returns to a vehicle with little coolant in it and drives away.
the temperature gauge does not register as it needs coolant around the sensor to work.
the motor cooks. Goodbye car for a few weeks. Goodbye big dollars.
an engine saver® low coolant alarm will help warn the driver of this disaster waiting to happen
same thing with a faulty water pump seal.
most water pump seals when they fail, first weep a little bit of coolant when the engine is running.
when the engine is switched off for the night, the coolant steadily leaks out under the vehicle.
next morning the engine is started and the vehicle driven away.
the coolant level is low, the temperature gauge doesn't read correctly and the engine cooks.
we hear these stories all the time from new customers.
that's not all. Coolant loss very rarely happens in a convenient place. Take it from one who knows.
it happens at the traffic lights in the city, out in the bush in 4 wheel drives, when mum is picking
the kids up from school. Towing the caravan or trailer on a trip. On the beach at fraser island.
on the highway many miles from help or the racq-nrma motoring organisation rescue tilt truck.
none of these situations are much fun. And when you do eventually get the vehicle to a repairer it
will probably be at least couple of weeks before you get it back. Not to mention the cost.
we manufacture engine saver® low coolant alarms to help prevent this nightmare happening to you
please don't become yet another person who is buying an engine saver® because they have
already .....d an engine in their vehicle. Buy one before you cook the engine, it's a lot cheaper.
an engine saver® can be fitted to any engine by a mechanic, auto electrician or home handyman
in less than an hour without drilling holes in radiators or tanks and using normal hand tools.
all models come with both audible & visual warnings and come with a 2 year warranty do you really want to drill a hole in your radiator? With an engine saver® you don't have to.
we have 3 types of coolant sensors, screw in, in-line hose sensors and underhose sensors.
brand new kit just added to our line up with easy fit screw in sensors

ايه العريضة دي كلها يامهندس سمير......... يادوبك نزلت لغاية العربية كنت بركب المساعدين بتوع شنطة الجيب بس المسامير كانت مزرجنة حبتين بس الحمد لله زبطت.
لوعايز تشوف اللينك بتدوس علي زرار الموس اليمين وتختار open new window
هاه يا أبو أحمد ..
أنا قاعد مستني من بدري أشوف نتيجة الحوار ده هاترسى على إيه ؟
إنت عارف .. اللي زيي ياما شاف في حوارات الحرارة دي .
إنت فين ؟
