During the start of your vehicle, the onboard computer system of the car works on these set of inputs and hence the process is known as ‘open loop.’

    A question: when or after how long should we switch off our engine after driving for along distant?

    1. Donald Ngota says

      It is necessary to leave the engine to idle for some time after driving for along distance, especially if you were driving at night with vehicle electrical accessories turned on eg. Wipers,defroster, headlights etc. This is to allow the battery to recharge fully so you can have enough voltage to restart your engine. For vehicles with turbo chargers, is advisable not to turn off the engine immediately to allow oil circulation for lubrication purposes and gradual cooling of the system. Hope this will assist

      Yes. That will be safer. Ideally, it should take only 2-3 sec.

    1.Why or what problem causes the car go off itself immediately after ignation when it has stayed for long without moving?
    2.why do brakes fail for that matter

    1. Phillip Moriss says

      1) Going out of Fuel can cause this. If the battery has run out because some electronics were turned on (like lights) during the idle time, can cause this too.
      2) If your car is turned off, your main brakes will not work – that is by default. Use the hand-brake to avoid disasters.

    What of diesel heavy cars, is it not necessary to allow the system to circulate the oil in the system?
    Turbocharged engines too, ain’t one supposed to give give it time to allow lubrication of the turbo?

  14. Daphier Saunyama says

    Thank you for the information, you need to specify which cars don’t need warming up. I have a 2003 Nissan hardbody 3.3v6. You need to warm it otherwise it starts with high revs and comes to normal when it warms up. Or I have a problem with my car.

  15. Johnson says

    Smeone seems to be pushing the pseudo “eco” nonsence really hard. In its owner manuals Honda always advises AGAINST bioethanol in the fuel and FOR warming up your engine. So the only reason for advising against warm up seems to be for saving a few grams of petrol? A few grams? Come on! Better switch off a few chinese plants and return to quality products that LAST.

  16. Ernesto Garcia says

    I have a 2005 Toyota Corolla CE and I usually let it warm up for a few minutes until the needle peaks above the “C” mark.
