Quite a few manufacturers have thought so over the years:
General Motors Diesel (Detroit) EMD, another offshoot of GM,
Nissan, Mitsubishi, Jenbacher etc etc have all made or are
still making V8 engines of two stroke persausion albeit
mainly diesel although some are offered in a dual fuel
OMC made a 300 HP two stroke V8 gasoline outboard.
Here is a listing for one on ebay, gives you some idea as to how big
this thing is.
In case is it word wraps, here is the item number: 4541539290
There is little information available on the web on these
There are a couple of used ones down at a boat yard where I quite
often work out of.
Very gas hungry beasts!
Yes Detroit made the -92 series in 6V, 8V and 12V. I have had dealings
with the 6 and 8Vs.
The ones I dealt with in MCI buses were both supercharged and turbocharged
though I understand that they were available with one or the other as well.
I particularly like the sound of the 6V. They put out gobs of power for
their day! They also leaked every fluid you put in them. Do not EVER run one
out of fuel unless you want to experience the defenition of frustration!
Perhaps the enquirer was thinking about crankcase-compression gas
transfer type 2-strokes such as Villiers, etc. This would become quite
tricky with more than one cylinmder, probably impossible with a V8,
although I have seen twin-cylinder 2-stroke Victa Lawnmower engines but
these were not very popular.
Of coures, the GM Detroit range (and others) mostly use pressure
scavenging from a blower etc.
You can have a multicylindered crankcase compression engine, but each
cylinder needs its own crankcase, hence the array of oil seals on
things like the Suzuki and Kawasaki two stroke triples of the 1970's
I'm sure that Yamaha built an experimental V8 two stroke along these
lines once, something to do with Formula 1.......... the fuel
consumption wouldn't bear thinking about.
I had a lot to do with Kawasaki triples in the '70's. They were certainly
powerful and reasonably reliable, but only at the price of flinging a fair
amount of oil and fuel out the exhaust port, a good deal of which would end
up on the pillion passengers back! The resulting avid consumption meant that
you could not drive even the 250 version from Bristol to London on the M4 as
Chievely and Heston were ten miles further apart than their maximum tank
capacity even if driven slowly.
With external compressor devices - like a super charger - any number of
cylinders can be fed. Rolls-Royce experimented with the "Crecy",a 12
cylinder two stroke Vee 12 based on the Merlin configuration. It got into
several prototype examples and showed very considerable gains in power, but
could not be made reliable despite the considerable resources of the world's
best engine manufacturer.
The predictable problem was that double the heat input at the piston face
could not be dealt with at high speed and power, resulting in continued
piston failures. The arrival of the gas turbine finally saw it off.
It was said that the characteristic wailing noise it made could be heard
five miles away on a quiet night!
If only Kawasaki had fitted reed valves like Yamaha....but I did rather
like the old flexi flyers.
The major proponents of the positively scavenged two stroke as applied
to motorbikes were of course DKW with their pre war racers, rumoured
to be heard in Liverpool all the way from the Isle of Man. I heard one
a few years ago, they are LOUD!!!!
The Crecy could have been made reliable if development work had
continued, but R-R had to concentrate most of their efforts on the
Merlin, and after the introduction of the jet engine piston engine
research took a back seat. I can strongly recommend the R-R Heritge
book on the Crecy for further reading. It really is a case of 'if
By coincidence I am browsing through 'Classic Grand prix Cars" by Karl
Ludvigsen, looking for some other info, I came across a couple of pages
on two stroke Grand Prix engines.
In the 1920's there was alot of interest in these engines.
Not V8, but eight cylinder were the Delage 2 litre experiment, the
Duesenberg eight 1.5 litre used piston-controlled porting with rotary
valve to control timing of inlet charge. Piston crown had deflector. Was
trialled for the 1926 Indy, but not raced. This engine was difficult to
start - it required the blower to be spun by electric motor before the
engine could be cranked. An over-running clutch then allowed the engine
to take over the drive. They had problems with this blower drive, and so
didn't race in 1926.
In the 1930's Zoller and Trossi were both trying two strokes where two
pistons shared one combustion chamber. The Trossi-Monaco had eight
paired, radial cylinders, air cooled, front drive, tested but not raced.
Quite a neat looking car.
Not eight cylinders, but Fiat was experimenting with a radical two
stroke 1.5 litre in 1926. This was the Type 451 -an opposed piston, 6
cylinder, vertical layout with one crankshaft at top, the other at
bottom. 1.5 litre, it could manange a high 6500 rpm and 150+ bhp, very
Appparently Porsche proposed something similar, but laid horizontally,
for Mercedes in 1938.
So...No Grand Prix V8 for you, but some other interesting two stroke
