In a dual overhead cam type of engine (or any other known today), camshafts will make 2 turns for every 1 turn of crankshaft. (Rotary engines are different)
is that the same if the engine has 2 camshafts (not overhead)
it's a 2 to 1 ratio For ALL 4 cycle engines, no matter how many cylinders, the crankshaft turns twice for every turn of the camshaft.
Every revolution since ours. We had the first sucessful revolution.
There should be no need to do anything with the distributor as part of a timing belt job, I've done it twice now on my '92 MPV V6. After you installed the belt with all the markings lined up, did you rotate the crankshaft, and if so, how many times? Don't forget that the crankshaft rotates TWO revolutions for every ONE revolution of the camshafts...so if your rotor is pointing exactly opposite from number one, give the crankshaft one more full revolution--all your markings should then be lined up and your rotor should be pointing at number one.
There is no firing order on a 1 cylinder engine. It just fires once every other revolution of the crankshaft if it is a 4 cycle or every revolution if it is a 2 cycle.
600 rpm / 60 = 10 revs per second. The intake valve opens on every other revolution (2 revolutions for every four-stroke cycle). This results in 5 intake valve openings per second!
Mercury experiences 3 days exactly for every two revolutions about the Sun. This is 88 Earth days in 1 Mercury year.
The camshaft spins at half the engine speed. The crankshaft spins 2 times for every one revolution of the camshaft
5000 revolutions in 11000m = 1 revolution every 2.2m Circumference is 2.2m Circumference is diameter times pi 2.2m dividied by pi divided by 2 (to go from diameter to radius) = 35.014cm
The cam shaft rotates 2 times for every rotation of the crankshaft. The pulleys are a 2-1 ratio. This means every revolution of your engine...RPM...your camshaft is rotating twice.
It takes the Sun 250 million years to make a full revolution through the Milky Way's galactic core. It rotates completely once every 31 days at the poles, and once every 27 days at the equator.
the mark on the camshaft timing gear needs to line up with the mark on the crankshaft timing gear to ensure the camshaft is in proper time with the crankshaft. Keep in mind that the marks will only line-up every other revolution of the engine due to the crankshaft spinning twice as fast as the camshaft.
