How does oil get thru all those bearings?

[DOCTORBILL]

I noticed that the Rod Bearings had a hole in them and the Rod end with the
bolts had a hole in it.

I am asking this almost knowing what the response will be, but would like to
have it confirmed.

Are these holes to feed oil from the oil pump at 40 psi or so to all the bearings?

And if so, are those holes all lined up such that when the crankshaft gets to a
certain position, the oil can squirt thru them all?

How is that last accomplished?

How does the oil get into the crankshaft and is it a continuous feed (how?) or
does it pulsate as some holes line up at certain portions of the rotation?

This seems like engineering brilliance and magic to me....

It's pretty simple actually Maybe this will help

Very Nice! Where is that diagram from?

So having the oil splash around and fly onto the Rod Bearings and Wrist Pins
is not required since it is pumped to those areas thru the Crankshaft...?

But splashing up onto the Piston Skirt is rqd for oiling the rings - yes?

From the suzuki factory service manual for the swift gt. Yes, there's no need for oil splash at all. The oil gets around really good on it's own. People actually make crank scrapers to stop the oil splash, so it doesn't end up hindering the crank's ability to move freely in the crankcase. Some people have made some nice looking oil squirters for the G series engines. They redirect oil to spray the bottom of the piston before it drains back into the oil pan. Best used in turbo/nitrous setups, or engines that are constantly under a heavy load. I'll post a picture of them if I can find them
