Not all 4 stroke engines are upright. How about the Chevrolet Corvair, the air cooled VW, a typical vertical shaft lawn mower. It doesn't matter as long as the oil sump/reservoir is located at the bottom.
What else can I help you with?
Why can two stroke engines operate in any position?
the gas of the thing their using or fixing
Do you find carburetor in 4 stroke engines or 2 stroke engines?
Both 2-stroke and 4-stroke engines have a carburetor.
How are two stroke engines lubricated?
Two stroke engines are lubricated by mixing special two-stroke oil in with the petrol.
What are advantages of two stroke engines over four stroke engines?
There are a couple, less parts for one therefore lighter. Also, 2 stroke engines fire every time the piston comes to the top. Which means every stroke is a power stroke. 4 stroke engines fire every other time.
What kind of engines are most gasoline engines?

Do riding lawnmowers have 4 stroke engines?
All Riding Lawn Mowers are 4 stroke engines
Are the tug boat engines are two stroke or four stroke?
All tug boat engines are four stroke engines, because this engine responces quickly in relation to maneuvering this kind of boat in any situation.
Why do most very large engines operate on two stroke cycle?
very large is the keyword here. for a very large engines that runs large machines, we need high power engines. two-strike cycle engines produce more power than 4-stroke cycle engines. that's why they are used. as they produce more pollution than 4-strokes, they must be limited to small spaced engines machines or large machines that required very high power.
Why two stroke engines are hi-speed engines and four stroke engines are hi-torque engines?
generally , two strokes are smaller capacity , shorter stroke, higher revs. for given engine capacity , long stroke /small bore = high torque / low revs short stroke/big bore = low torque / high revs
Why four stroke engines are not used for marine propulsion?
They are - most inboard engines are 4-stroke. But as with land vehicles, you can get a smaller engine with 2-stroke (or more horsepower with a smaller engine) so the small engines like some outboards tend to be 2-stroke.
Are 4 stroke outboard motor engines for boats going to be outlawed?
4 stroke outboard motor engines are unlikely to be outlawed anytime in the near future. 2 stroke engines probably will be outlawed. 2 stroke engines pollute the atmosphere. 4 stroke engines are standard gasoline engines like are in automobiles. They will probably be required to get better pollution control equipment, which will be easy. They will probably be required to be made more efficient, which will not be quite as easy. They will probably not be outlawed.
What is the purpose of the piston ring locating pins?
To keep the rings from rotating on 2 stroke engines. You will not see this on 4 stroke engines.
