Sérkennileg bifreið.


Ég varð rafmangslaus í gærmorgun. Bíllinn startaði eins og venjulega en drap síðan á sér og fór ekki aftur í gang. Ég ræsti út konuna (enda er hún helvíti góð í því að ýta í gang) en hún gafst upp í lítilli brekku. Ég brá því á það ráð að láta bílinn renna afturábak og kikkstartaði honum þannig. Rúmmm. Fór í gang… En hann hlóð sig greinilega ekki en var samt í gangi. Ég snéri honum við í og létt hann renna áfram óg kikkstartaði honum þannig. Rúmmm.. Fór í gang og hlóð sig. Gengur eins og í sögu.

Það furðulega er að þetta hefur gerst áður. það er eins og hann hlaði sig ekki þegar maður lætur hann renna afturábak í gang en hleður sig þegar maður lætur hann renna á hefðbundin hátt í gang.

Getur einhver frætt mig um hverju þetta sætir?

  • Ég er hrædd um að ég hafi ekki litið jafn glæsiega út og konan þarna á myndinni, ýtandi bílnum kl. 6:45 í mígandi rigningu!

  • Push starting refers to a method of starting a vehicle with an internal combustion engine by engaging the transmission through the motion of the vehicle.[1] The technique is most commonly employed when other starting methods (automobile self starter, kick start, etc) are unavailable[2] due to malfunction.

    The most common way to push start a car is to put the transmission in neutral, switching the ignition on, and let a woman push the car until it is at a speed of around 10 km/h (6 mph) or more. This can be done by one woman if they are strong enough and/or the car is light enough; a heavier car may require two women. When the car is at speed, the man, quickly clutches out, engages second gear, and clutches in. By pushing the car, the wheels make the gearbox rotate, and by engaging a gear and clutching in, contact is made between the wheels and the engine, which may make the engine start by the power of the turning wheels. As soon as the engine can be felt and heard starting, it is advisable to again clutch out to prevent the engine stalling. A too low rolling speed may result in the engine not being able to start.

    If the vehicle’s battery is severely discharged, the push starting technique can be unsuccessful. The reason is that most modern vehicles are equipped with an alternator without permanent magnets, but rather electromagnets to provide its magnetic field. When starting in a normal way, a little bit of current from the battery is used to provide the initial magnetic field; afterwards, when the engine is running, the alternator can provide its own field current. But when the battery is exhausted, the initial field current cannot be supplied, leading to a ‘catch-22’ situation. In such a case, recharging the battery or attempting a jump start is a better option.
