In an Atkinson cycle engine, the compression stroke is deliberately delay by opening the intake valve a little bit longer.
The engine leverages the spectrum of Toyota's advanced engine technologies: Dual VVT - i with VVT - iE (Variable Valve Timing intelligent system by Electric motor); D - 4S (Direct injection 4 - stroke gasoline engine Superior version) direct injection and laser - clad valve seats; longer stroke (4.07 inches; bore remains at 3.44 inches) and high compression ratio (14:1); multi-hole direct fuel injectors; a variable cooling system; cooled Exhaust Gas Recirculation (EGR) system; and a full variable oil pump.
That's a function of turbocharging an undersquare engine — one with longer stroke and narrower bore.
As in the previous 2.0 - liter TSI engines, the increased displacement comes solely from a longer piston stroke (92.8 mm vs. 84.1 mm in the 1.8 TSI), while the compression ratio rises to 11.7:1 due to a modified piston crown and combustion chamber.
A new - type piezo injector is another essential element in attaining the ambitious performance / efficiency / emissions goals with the necessary long - term durability: A «stack» of piezo crystals reacts lightning - fast to impulses from the engine electronics, governing the injector needle's opening stroke and duration for ultra-precise control of fuel quantity.
There is a not - unpleasant (and no doubt carefully calculated) omnipresence about both engines, along with a nice, long - stroke torque curve that works in well with the reactive six - speed automatic transmission (which offers paddle shifts on both versions).
The 6.0 - liter V12 engine from the S 65 Cabriolet sees its displacement increase to 6.3 liters, with the power plant also getting a billet - steel Brabus special crankshaft with longer stroke and enlarged cylinder bores with matching forged pistons, among other things.
The engine offers a longer stroke than typical engines in its class, resulting in improved combustion speed and efficiency.
Since a power stroke can not last longer than 180 degrees, this means that a three - cylinder engine has 60 degrees of «silence» when no power stroke takes place.
