Ok, we all know that devices that draw huge amounts of current can adversely affect gas mileage... but can someone explain why it does this?
Lets say that we have hooked up an inverter in our car... that allowed us to use 110AC... and i decided to put a microwave in my car, so i could make popcorn while on the road.
OR
Say I hit my head real hard and started doing pointless mods... and hooked up 15 enormous foglights on my car.... as well as 6 12" subwoofers in my car that i play non-stop while the car is running
now.... all these devices will get their power from the battery... which is continually being recharged by the alternator... which gets ITS power from the crank pulley via the alternator belt
the crank pulleys speed is dependant on RPM... and nothing more
my question is... HOW does a high draw device/devices actually add load to the engine? The alternator is directly connected to the crank... regardless of whether or not my microwave is in the car.... so doesent it generate the same amount of power regardless??
Can someone explain?
Like, i feel the idle drop when i turn on my defrosters.... i could feel the increased load
I just dont know why...
