Actually, most of the efficiency of the Skyactiv engine comes from how it manages to reduce intake charge / combustion temperature enabling it to run
much higher compression ratio than other engines.
With
a much higher compression ratio (13.5:1 versus 12.3:1), freer - flowing intake and exhaust, and more aggressive cams, it produces 80 additional horsepower for a total of 731 hp at 8250 rpm and 509 lb - ft at 6000 rpm.

«Because we pre-compressed the water, there is less shock - heating than if we shock - compressed ambient liquid water, allowing us to access
much colder states at
high pressure than in previous shock
compression studies, so that we could reach the predicted stability domain of superionic ice,» Millot said.
Early predictions are that caloric cooling systems could result in as
much as a 30 percent
higher efficiency than currently available vapor -
compression products.

The 2.0 L direct - injected

much more technologically advanced and fuel - efficient.
The effective -

much higher at
high engine speeds for increased efficiency and power.
Ford hasn't said how
much more mumbo we can expect from the eight - cylinder engine, but with changes that increase the
compression ratio the company says the V8 now revs
higher than the old car.
The engine uses a more rigid cylinder block,
high - strength crankshaft, heavy - duty connecting rods,
high compression - ratio pistons, cylinder heads with improved cooling, exclusive camshaft specs, a 2 - rocker arm design VTEC valvetrain system, heavy - duty intake valve springs, a unique EGR system, special long - reach spark plugs, a large throttle body, and
much more to get the job done.
