Thinner oil in Winter, thicker oil in Summer, all to keep quickly-moving metal parts from rubbing against each other. There's a little lesson in engines and their parts below, although I don't think the metal parts in ship engines move quite as fast.

Right there, lower right, is a pretty good representation of how a four-stroke engine works. Granted, it's a diesel--that's why no spark plugs, and the fuel oil--but the principles are all there. Quiz question: a prize for whoever can tell me which stroke each cylinder is in, from left to right. Bonus question (I don't know the answer to this one): how does the valve train work on this thing?
(from Cars and Trucks and Things That Go)
Richard Scarry is one of my favorite kids' authors/artists. My parents brought my old R.S. books here on Thanksgiving and I think I like them more than Tater Tot does, though she really likes the story where Abby the bunny goes to the hospital to get her tonsils out. My absolute favorite Richard Scarry book, and possibly my favorite kids' book of all time is his 1974 masterwork, Cars and Trucks and Things That Go. The blue car/boat in the picture above is my absolute favorite VW of all time, the WWII-era Schwimmwagen. The "desert jeep" is a Kubelwagen, also built by VW during the War.
To paraphrase j+a, good job, Richard Scarry.

OK, left to right my guess is 1) exhaust, 2) combustion, 3) compression, and 4) intake. As for the bonus question, I would have to agree that I don't have an answer either. It sort of looks like a few parts are missing that might go between the cam shaft and the valve stems. If the prize is tater tot, just let me know where Gma and I can pick her up at :-)
I think it is the standard running order 1. Intake, 2. Compression, 3. Combustion, 4. Exhaust.
Also, the valve train is the magically simplified red dot lifters. No more manually adjusting the valves every 3,000 nautical miles.
Do you need Richard Scarry's big book of stories with the lion on the cover? I scored an awesome copy that I'll send your way if need be.
Gee, I'm afraid Gma Terry(aka mamalynn) was right...I do need glasses. Upon closer examination with my genuine Sherlock Holmes combination magnifier and secret decoder ring, I now see that Chris is correct. Guess I should have used that in the first place or I could have just clicked on the picture and enlarged it but then how would I justify hanging on the the combination magnifier and secret decoder ring? Oh well...the new glasses are supposed to be here by Saturday. Keep on posting. Always enjoyable to hear what all of you and the VW's are up to.
I agree with Chris. The arrows help, thought the illustration is pretty good.
Diggin' all the VW illustration!
@everyone: Thanks for playing, and congratulations to Chris. Absent the arrows, we can deduce the position of the cylinders by looking at the valves, and also by noticing the position of the connecting rods in relation to the rotational direction of the propeller shaft. That Richard Scarry didn't leave much out.
Chris, your prize will be forthcoming when I decide what it is and you email me your address.
Alright,
