Mám diesel a kúri asi tak po... ...moment, Google Mapy... ...po 1400m.
Kúri, akože dovtedy sa nič nedeje a zrazu mi tam začne hučať vetrák naplno a z výduchov ide dosť teplý vzduch nato, aby o cca 3 minútky začalo ventilátor spomaľovať na nepočuteľné otáčky aby dosiahlo nastavených 22°C.

[mp3turbo]

nezavisle kurenie, k tomu pridavne elektricke spiraly vo vyduchoch to robi svoje... Mercededesy to mali vo vyssich modeloch tusim od roku 2005 alebo tak nejak, zerie to hravo dva az tri kilowatty takze na bateriu zahul ale ved komfort.

Videl som to na CLS320djesel 2008, nahodis v nejakych minus 7 stupnoch, 15 sekund a hrnie sa prijemne teply vzduch z vyduchov - motor este sedem kilometrov bez pracovnej teploty.

turbo: superb z tohto roka, klasika 2l nafta, kuri asi po 1 km, rucicka teploty vody sa zdvihne asi po 2 km v takom pocasi, ako bolo dnes (rano -3), nezavisle kurenie nemam, spiraly vo vyduchoch su vsak uz pekne dlho u vela aut. Samozrejme, olej dosiahne svojich 100 stupnov asi po 15 km pri 130 kmh (ale tam uz ta dialnica ubera na teplote).

menic z 12V na 48V, to uz neni zahul, tak sa to aj riesi, napr aj pri vyhreve okna

[SKiLEX]

jaky zmysel ma menit to na 48v?

ved aj tak baterka je 12volt, odteka z nej 3kw pri 12voltoch a to nezmenis


ak sa to meni, tak kvoli tomu ze pri 12voltoch neurobis dostatocne velky odpor aby to topilo a urcite nie preto aby to nebol zahul na baterku...

mne auto tiez rychlo zacne kurit... v tychto mrazoch ma skor rano serie ina vec.. nemam problem oskrabat lad z celneho skla - lenze ta namraza, ci co, je zvnutra. a to sa skrabat neda/da, ale bud je palubovka plna vody.../.. takze miesto toho, aby som nastartoval, a uz pocas skrabania sa zohrieval motor, vzdy urobim to, ze najprv oskrabem lad, a aj tak zistim, ze nikam nemozem ist, lebo vnutro celneho skla je cele "zarosenozaladnene"... je sice pravda, ze mi staci "vyjst" z parkoviska, prejst 50m, zastavit, a o 1 minutu uz rosa zacina miznut vplyvom tepla...

dajaky napad? pohlcovac vlhkosti? ma to vyznam? serie ma fakt len vnutorna strana celneho, ja nemam problem oskrabat zvonku cele auto..

Felipe, reklamuj auto, toto som v zivote nevidel na vlastnom aute ani pri -15 stupnov (fabia 1, berlingo, civic, superb).

The heated windscreen control unit -J505 (A) is located in the boot on the right under the vehicle battery. The control unit

for the heated windscreen -J505 receives the information from the operating and display unit -J255. After every cold start of the engine, if the ambient temperature is below

+ 5°C and Auto mode is set on the operating and display unit -J255. The temperature at the -J255 must be set such that the air conditioner is in operation and neither of the two vent temperature sensors (-G150,-G151) must measure more than + 35°C. The heating time is a maximum of 6 minutes (at -40°C), depending on the ambient temperature.

When selecting Defrost mode on the -J255 if the ambient temperature is below + 5°C. The indicator lamp in the Defrost button remains lit as long as the heated windscreen is switched on. It is activated only when the engine is running.



J The electrical resistance of the metal film in the heated windscreen -Z2 is approx. 1.9W. To deliver the maximum possible heating power of approx. 1000W to the windscreen, a voltage greater than the vehicle voltage is required. The heated windscreen control unit -J505 converts the vehicle voltage into a variable voltage of between 25 and 48V, depending on the vehicle voltage.

J To prevent the vehicle electrical system from being overloaded, the -J505 regulates the heating power of the heated windscreen. At a vehicle voltage of 12.70 V it is approx. 200W and is regulated infinitely up to 1000W at 13.10V. To prevent the vehicle voltage from collapsing when the windscreen heating is switched on, the -J505 permits a rise in the delivered output of a maximum of 200W per second.

J During activation of the windscreen heating the voltage at the fresh air blower -V2 is limited by the operating and display unit -J255 (to approx. 4V in Auto mode and to approx. 7V in Defrost mode).

J To prevent the heated windscreen -Z2 from being activated in the event of a short or open circuit, the control unit -J505 interrogates the resistance of the heated windscreen.

If the measured resistance is below approx. 1.5 W (short) or above approx. 2.5 W (open circuit or contact resistance) the -J505 does not switch the heating on, or shuts it off if it is already on.

J To prevent amplification of damage to the heated windscreen -Z2 (cracks or stone chips) as a result of overheating at the damage points concerned, the heated windscreen control unit -J505 either shuts down or does not switch on in the first place.

Notes:
◆ The additional heating heater element -Z35 consists of several layers of resistor elements with a joint heating capacity of 1000 W (actuation of all 3 inputs). These resistor elements have a positive temperature coefficient (resistance increases with temperature and current input decreases).
◆ The resistor heating elements are actuated individually. As however all are interlinked in -Z35, the current is discharged via the earth connection with the lowest resistance.
◆ -Z35 is designed such that - when switched on - the current flowing via any of the contacts can never exceed 35 A (immediately following switch-on, resistance increases and current decreases).
◆ Attainment of the maximum heat output of 1000 W (3 x 333 W) requires the temperature of the resistor heating elements to be low and an adequate supply of current by the alternator.

A87-0191
◆ As resistances of less than 10ωcannot be measured with sufficient accuracy using workshop equipment, it is not possible to determine a short circuit in the additional heater element.
‒ → Actuate relays for "low" and "high" heat output by way of "Final control diagnosis" function of appropriate engine control unit and in doing so measure voltage between the two contacts of connectors -A-, -B- and -C-.

Notes:
◆ Vehicles with diesel engine are currently fitted with an electric additional heater (heat energy is added to air flow after exiting from heat exchanger).

=> Audi Sales Range
◆ Vehicles with diesel engine and "auxiliary heater" as optional extra may not be fitted with an electric additional heater depending on vehicle control system. On such vehicles, this function is assumed by the auxiliary heater, which operates as a fuel-driven additional heater (by adding additional heat energy to the coolant).

=> Audi Sales Range

=> Auxiliary heater
◆ Vehicles with petrol engines are not currently equipped with an additional heater.
◆ Checking actuation of heating elements

=> Relevant Diesel Direct-injection and Glow Plug System Workshop Manual; Repair Group 01

=> Current Flow Diagrams, Electrical Fault-finding and Fitting Locations binder
◆ On vehicles with electric additional heater, operating and display unit for air conditioner/Climatronic -E87 (heating) actuates engine control unit via bus system (control unit with display in dash panel insert -J285 is interface between convenience and drive train data buses). Control unit then decides whether to switch on additional heater. Depending on engine control unit version, display appears in various engine control unit measured value blocks to indicate why additional heater has not been switched on or that it has been actuated.

=> Relevant Diesel Direct-injection and Glow Plug System Workshop Manual; Repair Group 01
‒ -E87 (heating) transmits request for cut-in of electric additional heater via bus system to engine control unit (and to additional heater control unit -J364) if:
‒ -E87 (heating) is encoded for diesel engine (depending on -E87 version, not mandatory)
‒ Ambient temperature determined is less than 5 °C or has been at least once since ignition was switched on
‒ Engine is running
‒ Specified vent temperature calculated by -E87 (heating) was greater than 45 °C and is still more than 40 °C
‒ Coolant temperature transmitted by dash panel insert and calculated by -E87 (heating) is less than 70 °C (under certain conditions less than 80 °C)
◆ Electric additional heater is only switched in by diesel direct-injection and glow-plug system control unit if certain conditions occur simultaneously.

=> Relevant Diesel Direct-injection and Glow Plug System Workshop Manual; Repair Group 01
‒ Engine control unit switches on additional heater if the following prerequisites are met:
‒ Operating and display unit for air conditioner/Climatronic -E87 (heating) transmits request via data bus system
‒ Engine speed greater than 600 rpm
‒ Coolant temperature less than 70 °C (less than 80 °C at very low ambient temperatures)
‒ Capacity utilisation of alternator -C less than 60% (only with electric additional heater)

Ked mam 1000W a ide do toho 12V tak mi tecie prud 83A, ked mi to jednotka prehodi na vyssie pisanych 48V tak mi tam ide 20A (a to je zataz na altik, nie na baterku), taktiez elementy Z35 o ktorych sa tu bavime, cim viac rastie teplota tym je vyssi odpor, a tym mensi prud tecie, neboj, oni si to velmi dobre vymysleli.

mne auto tiez rychlo zacne kurit... v tychto mrazoch ma skor rano serie ina vec.. nemam problem oskrabat lad z celneho skla - lenze ta namraza, ci co, je zvnutra. a to sa skrabat neda/da, ale bud je palubovka plna vody.../.. takze miesto toho, aby som nastartoval, a uz pocas skrabania sa zohrieval motor, vzdy urobim to, ze najprv oskrabem lad, a aj tak zistim, ze nikam nemozem ist, lebo vnutro celneho skla je cele "zarosenozaladnene"... je sice pravda, ze mi staci "vyjst" z parkoviska, prejst 50m, zastavit, a o 1 minutu uz rosa zacina miznut vplyvom tepla...

dajaky napad? pohlcovac vlhkosti? ma to vyznam? serie ma fakt len vnutorna strana celneho, ja nemam problem oskrabat zvonku cele auto..

nepisal si par stran dozadu ze mas nove auto a v tip top stave? toto nerobi ani moskvic kamos, ak je v zaruke reklamuj to, neni to normalne, niekde mas riadnu netesnost a vlhkost ti ide do auta ale riadne.

[killswitch]

Felipe to mas nove auto? pozrel by som, ci niekde nie su upchate odtoky, niekade ti ide do auta vlhkost. to by sa na novom stavat nemalo. kabinovy filter si kedy menil? chladic a klima su ok? mne sa to zacalo diat na 12 rocnom a testujem teraz ryzu v ponozke uvidime, ci to vysaje nejaku vlhkost, zrovna dnes som to daval do auta.

alebo normalne pouzivat klimatizaciu...

nechce sa mi citat tie dlhe citacie, mozno zajtra

chapem ze cim viac voltov tym mensi prud, ale mas 12 alternatory? nemas... alternator je stale len 12voltovy, stale z neho odchadza 12voltov a 83A... az potom sa to premeni na 48 abo kolko

tak si to pls precitaj, a hlavne ako funguje upvolting a konvert napatia (priklad je blbe trafo / spinany zdroj), nemoze z 12V altika do jednotky ochadzat 83A pre krista )), cela elektrika v mojom aute tolko nezere (50A-70A).

alebo normalne pouzivat klimatizaciu...
...kila snehu na kobercekoch este asi nebude tento pripad

klima pod 0°C ani nemrazi vyparnik, ale vyuziva sa nativny jav, v systeme nie je velky tlak, v praxi to funguje tak ze pomaly ani nevznika kondenz, takze od klimy to nebude.
