Source : Aston Martin DB11: first all-fresh V12 engine built
* brand fresh 600bhp has been V12 twin turbo 5.2-liter engine production, to be used for the next decade in addition to beyond the DB11 in addition to different types Aston
Aston Martin the client style was built from the first place of the fresh 600bhp 5.2-liter V12 twin turbo, in addition to that will the fresh authority will DB11 , the high-end credit types in addition to perhaps pioneering fresh SUV in addition to Lagonda saloon for ten years at least, in addition to possibly up to 15 years.
design-fresh via the ground to the AZ in Britain, in addition to the design of alloy block / prime known internally as AE31 in addition to replace the design AE28, aged 13 years – in addition to the V12 6.0-liter that will helped Aston re-launched in 2003 under the ownership of Ford with the DB9.
“This kind of is actually the one job for the next generation of the V12 engine, which will be at the heart of the strategic plan of the second century-Aston Martin to expand,” said chief executive Andy Palmer.
Palmer said the engine would likely be fitted on the first car production DB11, which can be retained by the maker, although the alternative plan could see that will the allocation for the client.
Prime Aston via the powertrain Dr. Brian Fitzsimmons oversaw the project AE31, which started off in design from the summer of 2012 in addition to moved quickly to test-fire in October of that will year to the green production of light in January 2013.
Aston continue to make the engine from the Ford factory work inside the plant in Niehl, Cologne.
uses AE31 same 21.5mm bore compensation in addition to 60 deg VEE corner as from the previous Generale 6.0-liter, easing manufacturing for, nevertheless have been redesigned every major elements
The bore is actually the same in 89mm – another dimension developed manufacturing equipment – nevertheless much shorter stroke to 69.7mm – in addition to therefore a reduction from the ability swept.
peak power is actually 600bhp at 6500rpm in addition to peak 700Nm torque at 1750rpm
still being finalized
economy numbers in fuel consumption in addition to emissions from the DB11, nevertheless Fitzsimmons speaks of 255g / km – 10G / km under / km 265g target – with further cuts come
“I’m determined to keep working on the engine team.,” he said.
in addition to the fresh V12 maintains the traditional injection fuel injection is actually not direct because of fears of increased production of particles with petrols DI “. I think we might be able to get This kind of under 250g / km we’re just not sure where the legislation is actually going on emissions , we have thus stayed away via GDI type of technology, “said Fitzsimmons
Aston are three parts: camshaft roller rocker, cam covers, timing variable valve device that will improvements the cam timing.
through the development of Aston used the test cells from the automotive division by Ilmore engines, in Brixworth, next to the Mercedes AMG F1 facility. “They have actually excellent equipment in addition to test cells in addition to we need This kind of kind of service,” says Fitzsimmons.
used during the development of Aston also AVL, German in addition to engineering consultancy for emissions testing in addition to verification.
in addition to the fresh V12 will 35KG was heavier than the previous 6.0-liter due to the addition of two twin-turbo scrolling in addition to associated plumbing in addition to radiator.
nevertheless the weight saving block design, pour the exhaust manifold in addition to crankshaft saved via 20kg, in addition to left. Net profit of 15KG
Aston chose Turbo Mitsubishi Heavy Industries over its competitors because This kind of is actually the best matching V12 engine characteristics were two features that will are valued at Fitzsimons: for WASTEGATE in addition to electrical twin scroll feed
in addition to scrolling twin is actually particularly suitable for V12 because This kind of divides the high-pressure air flow into two distinct feeds, one for each half-brother to the bank three cylinders.
