What is the year make and model you are asking about. Most gear driven cams are counter rotating in relationship to the crankshaft, while most belt or chain driven engines the cam and crank rotate in the same direction. Either way, there is no real benifit to rotating together or in different directions. The result is the same.
No. The crank sensor reads the crankshaft location and speed. The cam sensor reads the camshaft.
same as earth
Only some.
All planets in the solar system rotate, but not all in the same direction, Mercury, Earth, Mars, Jupiter, Saturn, and Neptune all rotate in one direction, while Venus, Uranus, and the dwarf planet Pluto rotate in the opposite direction.
yes they do
A third gear between them.
I am not sure what you are asking here, So I will try my best at guessing. Why does the earth rotate in the direction and the way it does, and all of the other planets rotate in the direction as well, and all of the planets orbit in the same direction around the star. All orbiting the same way. The milky Way Galaxy spirals again in the same circular orbit direction. I too wondered why does everything spin, rotate, orbit, in the same direction. Like a lot of science, This is only a theory, The theory I find that makes sense to me, is atoms and electrons spin in this way, If this spin conserves momentum, then our solar system, and galaxy, and all other galaxy's in the universe will spin the same. An interesting thought?
yes they should
The same direction as the fan and the drive axle (rwd only)
Mercury and Jupiter.
The crankshaft itself has no marks, the crankshaft pulley has one, it's white color. The same is true for the camshaft, it has no marks. But the camshaft pulley has a hole in it. That hole must alighed with the mark behind the pulley and the crankshaft should alighed with its own mark and the camshaft in the same time.
when its just two gears its rotating in the opposing direction unless both gears in question are being powered by a 3rd center gear
