Lots of motorcycles out there that are air cooled v-twins. Granted they are
limited in horsepower for their displacement. ;^) (that ought to bring out the
Harley guys)

What about us Indian guys )

With all the casino money, you can buy whatever engine you want. :-)

why isn't the Lycoming O-540 or the Continental O-520 an
inverted V?


They are derived from opposed engines, and the manufacturers thought
easier to retain the same cylinders and cylinder heads as their 4
cylinder counterparts.

OK so I just push my question back one generation: why is the O-360 not
an inverted V?

I'm asking more from a theoretical point of view. What is it that makes
the opposed configuration more attractive than the V configuration for
air-cooled engines? Likewise: what is it that makes the V configuration
more attractive than the opposed configuration for liquid-cooled engines?

There are new aircraft engine designs out the the Jabiru as an
air-cooled example and the Orenda as a liquid-cooled example. They
follow the same pattern that has become the norm.

There have been a number of aircooled inverted engines in the post WWII
period.

...and in the pre-WWII period! The deHavilland Gipsy Major being a
notable example.

I think one of the factors you're overlooking is vibration.

Certain engine configurations have less vibration due to the arrangement
of the reciprocating and revolving components:

A 90 degree V-8; a straight-6; ...

...and a flat-4.

A V-4 would have more vibration than a flat-4.

Yea, ever drive a Corsair V4? Even with a balance shaft they are not
smmoth.

Um, somebody check me, but didn't the Corvair come with only one engine:
a flat 6?

I spoke about an Indian motorcycle (in reply to the comment "that

most of the times for many in this group )

Big John,

I had got the Indian bikes message correct. I also met Ariel Saquare
Fours, the lot.

Best regards,

Best regards,

What bout the Moto Guzzi and Ducati riders? I remember embarrassing
many Harley riders with my old Guzzi T3.

Ya gotta learn to READ. I said CORSAIR. Like a Limey Ford from the
'60s.
I believe the engine may have also been used in the Transit van, and
is a close relative if not the same engine as the Saab V4.

Until a year or two ago, they were making them new down the road in
Gilroy, CA.

Too bad they couldn't make a go of it.

They were out of business a long time until a couple of years ago due
to a trademark of the name and owner wouldn't sell or some such
rig-a-ma-roll. New one I saw was a nice looking bike.

I had a WWII surplus military model and rode while I was an instructor
in the P-80 in Arizona. Rode for about 3 years and never laid down.
With the casualities in training I ended up selling to reduce my risk
of bad things happening.

Well, you're absolutely right that a V-4 would be expected to have a lot
of vibration.
