My People, Does AC Affect Fuel Consumption Of A Car? by Mohwin(m): 6:49am On Sep 13, 2017 |
Me and my freinds have had this discussion and we argued. Me i strongly believe that a car's AC has very little to do with the car engine, instead it is keeping the car windows down that causes drag and increase fuel consumption. I have seen people say they cant put on their AC because the car will consume more fuel. So i need more light on this pls. 8 Likes |

For city driving?? Yes it does affect consumption. But if you're talking about highway driving, then the effect on fuel consumption is very negligible, or nil sef.. It depends! 46 Likes |

Anything that demands more work/energy from your engine demands more fuel from your tank. Same way the more weight you have in passengers, the more your fuel consumption as long as it is the same car and other variables are constant 63 Likes 3 Shares |

With my own little knowledge, I don't think so, because the car A.C, have their own gas cylinder. I am open to correction. Modified: Thank you all for the corrections. ![]() 15 Likes 1 Share |

Every extra load on the engine directly increases the fuel consumption of the car. 7 Likes |

Compressor puts load on the engine....it's simple physics....the more the load the higher the energy consumption Just lie when you are in your home....you out AC..you pay higher bill than when you don't ...in car...the bill is fuel Did you do physics in secondary School at all ? Mohwin: 17 Likes |

Have you noticed that the sound of the Engine slightly changes when you put on the AC? It shows that there is an extra weight.. But, on the highly, it doesn't really have much effect on fuel consumption as it does in Lagos Traffic. 10 Likes |

Re: My People, Does AC Affect Fuel Consumption Of A Car? by Nobody: 8:22am On Sep 13, 2017 |
Yes it does. I'll say why later Modified. There is a direct relationship between output power and the speed of the rotatory or linear moving parts of the engine and hence the speed of the car. Assuming you are driving at a constant speed without AC, the moment you switch ON the AC, there is an additional load on the system, but because the input power is constant, the output speed reduces. This is noticeable when the car is moving at slower speeds, say less than 80km/h. If you must maintain the initial speed of the car before the AC was switched ON, then u need to increase the input power of the car to cater for the additional load occasioned by the AC switched ON. This is achieved by increasing the quantity of fuel being sent to the combustion chamber by increasing the pressure on the acceleration pedal. Therefore, you will discover that there is more fuel consumed when the AC is switched ON as compared to when it is not. It is this same principle that applies to electric power systems known as Load Frequency (speed) Control. 11 Likes 1 Share |

Of course. The question should be how big it consumes compared to when AC is not in use. 4 Likes 1 Share |
