Sentences with phrase «friction cylinder liners»

Technical highlights of the new Mercedes - Benz twelve - cylinder engine include dual ignition, three - valve technology, automatic cylinder shut - off, low - friction cylinder liners and modern lightweight design.

It is a development of the engine used in the 911 R and GT3 RS, with an upgraded valve train, a stiffer crank, low - friction cylinder liners, a new cylinder head design that dispenses with hydraulic valve adjusters and a 9000rpm redline - 750rpm more than the RS.

Not exact matches

Measures such as a rigid valvetrain, redesigned crankshaft and new cylinder bore liners help to reduce internal friction, while the redline is now set at 9000rpm — matching the smaller 3.8 but improving on earlier 4 - litre versions.

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.

Cast - in Silitec cylinder liners ensure low friction for the eight pistons.

It features a number of new developments, including friction - reducing plasma - based cylinder liners, a stiffer crankcase, redesigned cam followers within the rocker bearings and a revised scavenging system for the dry sump that is claimed to reduce oil recirculation by more than 40 %.

The crankcase is very rigid due to its closed - deck design — which means that the cylinder water jacket is closed at the top — while thermally joined, high - strength cylinder liners with twin - wire, arc - sprayed coating save weight, allow greater thermal transfer due to the thinner cylinder wall thickness and reduce internal friction.

Gravity - die sand - cast all - aluminium crankcase Weight - optimised crank mechanism with forged steel crankshaft Forged pistons with friction - optimised piston rings NANOSLIDE cylinder liner technology Air - to - water intercooling system Alternator management ECO start / stop function

Its cylinder liners and chain drive are optimized for minimal friction, and the oil pump is only driven as needed.

The engine features an aluminium crankcase with thermally - joined cylinder liners (to reduce internal friction) and integrated balancer shafts, a turbocharger with variable intake geometry as well as an improved 2,000 bar common - rail direct - injection system.

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.

The block is a high - pressure, die cast aluminum unit with cast iron bore liners and aluminum cylinder heads; cast aluminum pistons with low friction rings are fitted to forged steel connecting rods.

The cylinder liners are surfaced with a low - friction aluminium - silicon alloy.

A cooling control spacer positioned in the water jacket surrounding the cylinders helps control warm - up and operating cylinder liner temperatures to reduce friction.

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).

To further minimize piston friction and lower fuel consumption, the cylinder bore is widened at the lower end of the cylinder liners.
