Engine AC question

AC question

hey I notice that when I turn the AC on my cars seems to lose horsepower.....and when accelerating it takes longer than normal to get up there......Does NE body have this problem?

I think that's normal. don't worry and don't turn the AC to high.

We have a I-4 engine, its normal, reason why I dont use mines

It's normal. But a HVS can help.

whats a hvs?

You can't get "something for nothing"-- the compressor is run from a belt on the engine. Turn on the air conditioner at home, and watch the electric meter spin faster. It takes energy, either mechanical or electrical, to run that compressor. If it were electrical, it would still require engine power, as the alternator would have to work harder to keep the battery charged -- and the conversion from mechanical to electrical to mechanical again would result in even more losses.

The engine doesn't necessarily "lose horsepower", it's just that the power it's making is now going in part to run the AC (of course, the heat the AC gives off from the condensor is returned in part to the radiator, which can raise coolant temperature-- too high coolant temperatures *can* reduce power. And if your intake sucks in hotter air as a result of the extra heat given off by the radiator and condensor, as well as heat in mechanical losses in the compressor, then that can reduce power.

As others have said-- it's a 1.8 litre inline 4. Every parasitic loss counts.
