Have you seen an arrow before ? Do you know y the mouth is pin ,,,? Two wen you look at planes you see the front mouth narrow that's to tell you what' air does ,Air can cus a very big setback to any movement .if u face your umbrella towards breeze you will understand what am trying to say , cars consume fuel wen u are using it on city drive but wen on a high way with AC on it helps the engine to serve you better also reduces the fuel intake .your car SNICK's in trough the air without any hindrance .Am a Meckanic from ghana I study it. |

positivelord: Be it factory fitted or industry fitted....it is load on engine....it will be an additional load and it will increase fuel consumption....depending on the engine capacity and the capacity of the compressor that the AC uses...but it must affect consumption It's simple physics ...why debate this ? 1 Like |

kokostick: Most vehicle air conditioners (a/c) require engine power to operate. ... Using the a/c can increase fuel consumption by up to 20% because of the extra load on the engine. The a/c load depends on the vehicle's interior size, the outdoor temperature and other operating conditions. http://www.nrcan.gc.ca/energy/efficiency/transportation/cars-light-trucks/buying/16740 |

It does, but the comfort pays you back. The amount is negligible if your engine is healthy 1 Like |

wunmi590: gas cylinder ? na him they power himself ? it adds more pressure to the engine which in turn increases fuel consumption . |

The car AC uses power from the car battery. When your car is going slow on traffic jam with your AC on, or it is parked and engine on with the AC, the battery will be running low. The engine have to rotate more to power the battery to keep your AC going. On the other hand, when on the high way, the car engine is rotating fast charging your car battery leaving the power consumption of the AC negligible. After doing pharmacy, am here talking engineering. Na wa for me. What do i know couple with the fact that i do not have a car of my own yet? |

Re: My People, Does AC Affect Fuel Consumption Of A Car? by Livinusc(m): 11:15am On Sep 13, 2017 |
From my own little idea,i think the car AC uses battery in stead of engine because without battery the car AC can not work even if u start the engine so i think that is the little i can offer. |
Re: My People, Does AC Affect Fuel Consumption Of A Car? by msylva2147(m): 11:26am On Sep 13, 2017 |
but I was made to understand that Peugeot 406 consumes more fuel when the AC is not on. |

AmuDimpka: But very negligible if you have a good engine. It's when the engine is getting weak you even feel change in sound when you put the AC on. |
Re: My People, Does AC Affect Fuel Consumption Of A Car? by olisamedua: 11:41am On Sep 13, 2017 |
We might also need to consider the aerodynamic drag (ie. air resistance) when the windows are down if you aren't using your ac. This will add more load to the engine. See detailed study on this here: http://www.autoglassofamerica.com/maintenance/which-is-more-fuel-efficient-windows-down-or-ac/ |

hinograce: Once the engine is set to work after being powered by the battery, everything is on the engine only if the alternator is very efficient. The effect of extra loads is on fuel consumption not on the battery... |

please does lowering your AC reduce fuel consumption in cars.. cos most ppl like setting their AC level at 1 or middle |

Cars differ. Peugeot, Mercedes, Toyota, etc. All differs. The more modern a car, the better in fuel efficiency under AC. But Peugeot is credited with high efficiency so that even under ac use, its less fuel consuming compared to other cars. 406 comes to mind here. |
Re: My People, Does AC Affect Fuel Consumption Of A Car? by clemz85(m): 2:10pm On Sep 13, 2017 |
Mohwin: Let's think like this, the injector nozzle does not expand at any cause, the fuel pump pressure remains stable and is not affected by how engine works, so how on does AC consume fuel? I am a driver with good maintenance culture, from my experience what consumes fuel has to do with bad plugs and inappropriate revving, People complain AC Fuel Crack because your stays on more with AC if you are driving around time and encountering hold ups I stand to be corrected |

Re: My People, Does AC Affect Fuel Consumption Of A Car? by Dannyonos26: 2:34pm On Sep 13, 2017 |
With AC on, there is reduced air resistance for the external surrounding. This helps in reducing the opposing force if the car, and in turn saves fuel consumption over a long Distance. As can be seen in the equation F=mg. With g as the acceleration due to gravity. |

the compressor on its own is a mini engine..so when AC is on, its like running two engines from the same fuel tank 1 Like |

Your correct in terms of air resistance...even of AC isn't on...the windows are closed it will still save....the truth is AC consumes more fuel Simple physics Dannyonos26: |
