Cylinder head and exhaust gaskets are beefier than before, and perhaps most importantly, the main bearings are now topped with a polymer coating that dramatically reduces scoring and prolongs life.
Producing 148bhp, it features cylinder deactivation tech and common rail injection, while the internal friction has been reduced over the 1.4 - litre by the use of a new fully variable, map - controlled oil pump and a polymer - coated first main crank bearing.
There's also 12 % less internal friction thanks to spray - coated and mirror - finish cylinder bores, limiting knock and engine weight vs. the previous iron liners, Nissan says.
And instead of liners, the cylinder bores feature a twin - wire arc - sprayed coating, which results in a significant reduction in engine weight.
A first for a production engine, the cylinder bores feature a twin - wire - arc - sprayed (TWAS) coating, a new process that results in impressively low friction and running surfaces that are twice as hard as conventional cast - iron cylinders.
The Continuously Variable Valve Timing Control System (CVTCS) includes an intermediate lock function on the intake side, while the use of spray - coated and mirror - finish cylinder bores (versus the iron liners) provides an estimated 12 percent reduction in internal friction, which also improves anti-knock performance and reduces engine weight.
Mirror bore coating technology is a process in which the cylinder walls are sprayed by a special plasma jet.
While the VC - Turbo engine's multi-link system limits the lateral movement of the connecting rods within the engine — a cause of piston friction — Infiniti's mirror bore coating technology further reduces cylinder friction by 44 %.
Key changes to the engine's design include a thermal - insulated resin intake port, Direct Injection Gasoline (DIG) system, variable tumble control valve, mirror bore cylinder coating, variable displacement oil pump, intake e-VTC and cooled external EGR.
It also uses a spray coating instead of traditional cylinder bore liners for reduced weight.
Rated at 188 horsepower at 5,600 RPM and 177 lb - ft of torque at 1,600 - 5,200 RPM, the 16 - valve DOHC aluminum - alloy inline 4 - cylinder engine includes a 10.5:1 compression ratio, Continuously Variable Valve Timing Control System (CVTCS), spray - coated and mirror - finish cylinder bores, a variable pressure oil pump and a low - pressure EGR system, which helps lower exhaust gas temperature and improve knock sensitivity.
The engine also utilizes mirror bore cylinder coating to help reduce engine weight by around three pounds and reduces friction between the piston ring and the cylinder wall (versus heavy cast iron cylinder liners).
The new TCe engine incorporates the latest Alliance - developed innovations, including Mirror Bore Coating, a cylinder coating technology used for the Nissan GT - R engine to improve energy efficiency by reducing friction and optimizing heat condCoating, a cylinder coating technology used for the Nissan GT - R engine to improve energy efficiency by reducing friction and optimizing heat condcoating technology used for the Nissan GT - R engine to improve energy efficiency by reducing friction and optimizing heat conduction.
And instead of liners, the cylinder bores feature a twin - wire arc - sprayed coating, which results in a significant reduction in engine weight.
Plasma coated cylinder liners, a central oil supply through the crankshaft with larger bearing diameters, larger connecting rod bearings and the rigid valve train with shims to provide valve clearance compensation all carry over from the 2018 911 GT3.
Built almost completely from a high - strength silicon - aluminum alloy, the cylinder bores make use of a twin - wire - arc - sprayed (TWAS) coating, a process that results in impressively low friction and running surfaces that are twice as hard as conventional cast - iron cylinders.
