Prasom.
The Alfa Romeo Twinspark 2.0 liter inline-4 DOHC engine with a compression ratio of 10:1 like it’s namesake uses two spark plugs per cylinder. If you look at the engine cover above, you will see a series of domes embossed on it, two domes per cylinder, one larger and one smaller. This is because the new 16 valve Twinspark engine’s two spark plugs per cylinder are sized differently, one is a larger spark plug (14mm diameter) and one is a smaller spark plug (10mm diameter). Twinspark operation helps reduce unburnt fuel in the combustion process. Alfa found that under normal conditions, a single plug could ignite an air/fuel ratio of 17:1, whereas twin plugs could ignite a mixture as lean as 20.8:1. The engine also features Variator - Alfa Romeo’s variable valve timing application. Alfa Romeo’s Variator operates on the intake camshaft via hydraulics, retarding timing by 25 degrees at engine speeds up to the 3,000 to 4,000rpm range. As the revs pick up, oil is pumped into a chamber in the Variator which alters the relationship between the camshaft and the pulley. At a certain point between 3,000 and 4,000rpm, the Variator deactivates and engine runs at the original advanced timing. The Alfa Romeo TwinSpark engine also features a variable geometry intake plenum, which alternates between a short intake path and a long intake path depending on engine RPM. You want a longer intake path with a limited capacity at low engine RPMs to increase air flow speed, and a shorter but wider intake path at high RPMs so that more air can enter the combustion chamber. There is apparent lack of torque at engine speeds of below 3,000rpm but anything after that the engine surges forward in a thrilling VTEC-like manner. And the sound is AMAZING. The trademark Alfa engine note clearly shouts out to you - “I am a performance engine. Rev me hard. NOW!” - and is very very addictive.
Arba jeigu nuo 2002m. tai bus ne TS, o JTS.
Apie sita irgi reikia info?
wow. moki pakopinti. Dabar reiktų netingėt ir skaityt angliškai tiek daug apie kažkokios alfos variklį?
Starco, galiu dar baltarusiskai imest. O siaip cia zmogus labai domejosi, tai negi gaila…
nevaliuha?
tas geras su oil pump + variable valve timing application iki siol maniau kad tik japonai gamina tokius dalykus.
iki kiek per simta jama tas tavo motoras o ne samones cia kopink
Stulpas dar arklys, ir kilovatas svarbu su sukimo momentu , ir siurbliukas kuro sanaudoms
Hmmm, vakar pardaviau savo Fiat Brava, dabar mąstau, gal parašyti kokį nors veikalą apie pačius “kokybiškiausius” Fiat/AR/Lancia automobilių mazgus .
diobrin, būtinai parašyk
Siap smagiai tas motoriukas nuo 3K pradeda suktis… Kaip is 1.8 tai kw beveik tiek pat kaip pas vw group 1.8 Turbo siap uzskaitom situos motorus… nors teko viena remontuoti… taciau nelbaia pavyko…
nes su bloku buvo problemos
jei kalbant apie 156 sedana, tai 1.6 ant popieriaus renka per ~10,5s, 1.8 per ~9.3s, 2.0ts per ~8.6s, o 2.4jtd ne tik valit bet ir ekonomiskas ir patikimas.
paasikinkik kasnors neismanusiam 10:1 kas tai??
cu> Šiaip aš nesu labai priešiškai nusiteikęs prieš itališkas auto, bet kai kurie jų sprendimai, tokie, švelniai sakant, nesuprantami . Tačiau didelis + jiems už automobilio išvaizdą, tiek vidaus, tiek išorės, taip pat dyzeliniai jtd varikliai patikimi ir galingi
, o benzininiai be turbinos turi tiek kw, kiek pas kitas auto tų metų su turbinom (kalbant maždaug apie 95 metus). Su TS aišku atskira šnekta
bl cia tik truksta ismeikto kirvuko, padekt ir i upe, kad zmoniu negazdintu
