Larger engines have more reciprocating mass and larger "support" components such as oil pumps, manifolds, valves, flywheels, etc. All of those rob power just to support the basic engine before there is any power left to turn the wheels. And that is just the basic engine. Then you get into the vehicle systems required to support larger engines.

True.. the increase is not linear. But, it's there.
Meantimes, we're seeing a lot of technology appear which is heartening. Compression ignition is having a renassiance. The FAA has certificated at least one and maybe two FADEC systems on flat motors, both compression ignition. (Fully Automatic Digital Engine Control). Maybe we will see Porsche return to the market. A friend flew behind one, loved it, and wasn't happy to have to replace it.
This indicates that electronic controls can be and are being built which are rock reliable - I can get out and walk if the Ford quits. I don't have that option in the Cessna.

The thing missing from this thread is scale factor. This seems to be a factor of basic physics. Moving the reciprocating mass of any reciprocating engine is a big issue and not easily managed. The other stopped is burn rates. These also can't be scaled because the process has a fixed velocity.
Balancing is not the answer as that is a whole engine issue. But, when the connecting rods aren't strong enough to pull the pistons back down (yes, they usually fail in tension), you have big problems.
The combination of these two is why ship engines with a 1 meter bore and a two and a half meter stoke only run at 100+/- RPM are only about 3kw/l (~4Hp/l), but they run a long time without an overhaul.

A friend is a metering and two - way tech for Transcontinental or whomever they are this week. We were looking at the big pump engines they use - these were Gardiner-Denver but they had Nordberg radials also - and I asked him about engine speeds. He said 500 RPM would horrify them. Interestingly, and you might know how this is done, some of their engines were two-stroke with turbochargers. How do you get that to work?

You burst my bubble! I restored my Dad's 1968 Type III Squareback VW Station Wagon and brought to Australia. I thought it was the
first EFI vehicle built and have been telling people that. From what you noted below obviously I was incorrect! AW S#!T!

Don't forget the Jetfire Olds. For EFI, you can't disallow the 58 Chrysler
and DeSoto. There is one restored and still running.
The electronics of the time were not very good. The only way to make spark
plugs live in my '63 Corvair Spyder was to use
a Holley transistor ignition. When Rodenfels Chevrolet ruined the motor and
Chevrolet invalidated my warranty. (I was
Service Manager in a Ford dealership at the time) I removed the ignition and
got rid of the car. Later, we put the ignition on
a 1957 supercharged Ford we were racing. It then failed on us at the '66
Springnationals in Bristol, Tenn. When the Holley
rep told us it would never survive long-term in an automotive environment,
we trashed it. I've not been comfortable with
anything electronic in an automobile since. JWID

OK, that's how. Once it gets hot I see how it works. He did mention they took some tweaking to start, but they are seldom stopped ao it doesn't matter a lot. The supercharged GM stuff I'm familiar with - we see a lot of them on old gensets. Detroit Diesel division.
I was on the roof of our co-lo provider (TelX) hanging a data radio this afternoon, they've just installed 3 Cummins 1.5MW sets up there. Honking BIG V - 16, four turbos per engine. They look to have an electric oil pump behind the starter, I assume they preoil them before startup. Electric starters instead of air. And a battery bank which would make any dry camper envious. I'll wander over sometime onTest Day, I want to watch one of them spool up and take load. All the offshore guys use EMD sets, I expect they're a bit pricey for standby service.

Johnny,
Most of the humungus diesels are two stroke. Some are piston port (like the little engines you know) and others are uni-flow (they have exhaust valves like a old GM 8V-92). The turbo-charger is just like any other. what you have to remember is that the exhaust opens while there is still a lot of pressure in the cylinder. That makes enough cascade for the thing to spool up.

rob,
Bendix developed the first EFI in the early '50s. It was going to be
installed on the 1957 Rambler Rebel. They couldn't get
all the problems solved, so none were ever sold to the public. I did see
one on a '57 Rebel that an American Motors
engineer was drag racing in 1962. I noticed it because I was the Parts
Manager in a Pontiac/Olds/Rambler dealership
at the time, Wish I had the good sense to persue the technology at the
time. Oh well!

Oops........ Forgot to mention that when Bosch needed to meet emissions and
transistor had replaced the vacuum tubes, they
bought the rights from Bendix and developed the dependable injection.
Funny, then GM used Bosch and Bendix to develop
the 1975 Cadillac injection. So the whole thing came full circle.

Gary,
The system on the VW is Bosch; they put it on the '68 VW first and made a lot of modifications in 1970 because it had problems. Once
they got is sorted it went on BMW's followed by Mercedes. Not the same system just the technology.
My Kraut genes can't believe the Yanks beat the Krauts, however, my Yank upbringing says WAY TO GO!
My Aussie side is going downstairs and grab a beer!
;-)
By the way Hamilton Standard built the first electronic cabin pressure control system in the 1960's it was an analog computer and
was a REAL PITA! The reliability SUCKED. In the 1970's they developed a digital replacement. The units went on the B727 followed by
the B737.

Johnny,
That is probably a pre-oiler for the turbochargers only. It these are instant-response units, it may be a whole engine oil pump and the unit probably has heaters in the lube oil and jacket cooling systems. One of these I used to know was good for 8 seconds to full load. ---> Can you Say - Boom, Its Running?
A lot of the utility peak load units are EMD. They can also be found in ships and about three quarters of the rail engines in use. The reason you don't see them lots of other places is that EMD does not build "real human" size engines. They started with a 567 line, upped that to 645 and finally 710 today. Those number a cubic inches displacement PER CYLINDER.

Yes, they'r heated. All of mine are as well. We normally buy what's called a 'hospital package' which is power in ten seconds or less. Mine (somewhat smaller than the ones I refer to) normally take load ijn 4.5 seconds ion the old 'big cam' engines, and 5.5 on the new ones. The new ones crank at idle speed and ramp up, it takes an extra second. We still have tubes (!) in the big transmiotters,, if they don't repower in about ten seconds they have to run through the startup cycle again. Ten or less, they can take full power without problems.
My offshore buddy said "The EMD folks sell you a GM locomotive, and just leave the locomotive part off of the engine and alternator". Georgia Power peak shaves here with combution turbines either oil or natural gas fired. They say they aren't particularly efficient but the cost per KW to build one is miniscule compared to a steam plant.
It would be a travesty, but someone needs to make a jet powered GMC 'dragster' for show at the races.

I worked for Citi bank in Sioux falls for a bit.
they have a huge 2-3 acre 3 story building that houses a call center and credit card processing mainframes.
On day they said they were going to test the back up generators so you may notice the lights flicker. They were going to have the power company cut ALL power to the building which would kick on the generators. No warning just yank the power!
at lunch I went out side to be greeted by the roar of 2 huge diesel generators cranking away. I never saw any flickering....
The generators were the size of a short container.
I was impressed

In my opinion - there is a HUGE difference between:
- developing the first EFI
and
- installing/selling it on a few cars (as several US manu's did)
and
- putting it into true "production" (as VW did!).
I had a 76 Cadillac Seville that might be considered the first EFI system that came "standard" on a US car. It was an option on non-Seville Caddy's.
I'd personally still be OK saying that your Squareback was the first "production" EFI...

When I sold my Seville - I threw in my manuals and immediately regretted it. I doubt the new owner even looked at them!
I had many issues with the EFI in the Seville - but the last repair was a cold solder joint in the analog computer. Once everything was sorted out - it purred perfectly.
I had a Porsche 914 that would have had a similar EFI system as the Squareback - but some hooligan had pulled it out and replaced it with dual Dellorto dual throat carbs. It was a common "fix" that Joe Sixpack would implement when he couldn't understand the "new fangled technology"...
If/when I get my hands on a GMC Motorhome - I'm hoping it has EFI. I was never a huge fan of the Quadrajet...

We exercise ours weekly loaded. And, any time we're at one of the plants late at night, I grab the powerline disconnect and haul it down and see what happens. Over the years, I've sttod there in the dark silence, even though the set tested properly that week.
This is why, every month or so, I go out and fire off the Junkerac and turn on the roof a/c or heat pump and run it for an hour. The small gensets are even more susceptible to sitting than the large ones.

I worked for Citi bank in Sioux falls for a bit.
they have a huge 2-3 acre 3 story building that houses a call center and credit card processing mainframes.
On day they said they were going to test the back up generators so you may notice the lights flicker. They were going to have the power company cut ALL power to the building which would kick on the generators. No warning just yank the power!
at lunch I went out side to be greeted by the roar of 2 huge diesel generators cranking away. I never saw any flickering....
The generators were the size of a short container.
I was impressed
