Alfa Romeo Twin Spark izinjini

Uchungechunge lwezinjini zikaphethiloli i-Alfa Romeo Twin Spark yakhiqizwa kusukela ngo-1986 kuya ku-2011 futhi ngalesi sikhathi izuze inqwaba yamamodeli nokuguqulwa.

I-Alfa Romeo Twin Spark 4-cylinder injini kaphethiloli yakhiqizwa kusukela ngo-1986 kuya ku-2011 futhi yafakwa cishe kuwo wonke amamodeli e-Alfa kusukela ku-145 encane kuya ku-executive 166. Ngokusekelwe kumayunithi ochungechunge lwe-TS, ukuguqulwa kokuqala komndeni we-JTS-engine zakhiwe izinjini.

Okuqukethwe:

• Isizukulwane sokuqala
• Isizukulwane sesibili

Izinjini zokuqala ze-Alfa Romeo Twin Spark

Ngo-1986, injini engu-75-litre yolayini omusha we-Twin Spark yakhishwa okokuqala ku-Alfa Romeo 2.0. Kwakuyiyunithi ethuthuka kakhulu ngaleso sikhathi enomjovo kaphethiloli we-multiport, i-aluminium cylinder block enalokho okubizwa ngokuthi ama-wet liners, i-timing chain drive kanye nekhanda le-aluminium elinepheya lama-camshaft alawula ama-valve ayisishiyagalombili kuphela. Ngokushesha uchungechunge lwanda ngenxa yamayunithi amancane ngevolumu yokusebenza ngo-1.7 no-1.8 amalitha.

Okugqamile okuyinhloko kwamayunithi anjalo kwakuyisistimu yokuthungela enamakhandlela amabili nge-cylinder ngayinye, okwenza kube nokwenzeka hhayi nje ukuthuthukisa ngokungathí sina ukuphelela kokuvutha kwengxube ye-fuel-air, kodwa futhi kwenze kwaba nokwenzeka ukusebenzisa injini ngemodi yokonga kodwa futhi izingxube ezimbi kakhulu. Esizukulwaneni sokuqala se-motor, kwasetshenziswa amakhandlela amabili afanayo futhi atholakala ngokulinganayo.

Umugqa wawuhlanganisa amayunithi amandla umthamo 1.7, 1.8 kanye nezinhlobo ezimbili zezinjini 2.0-litre:

1.7 amalitha (1749 cm³ 83.4 × 80 mm)

I-AR67105 (115 hp / 146 Nm)

I-Alfa Romeo 155

1.8 amalitha (1773 cm³ 84 × 80 mm)

I-AR67101 (129 hp / 165 Nm)

I-Alfa Romeo 155

2.0 amalitha (1962 cm³ 84.5 × 88 mm)

I-AR06420 (148 hp / 186 Nm)	I-Alfa Romeo 164
I-AR06224 (148 hp / 186 Nm)	I-Alfa Romeo 75

2.0 amalitha (1995 cm³ 84 × 90 mm)

I-AR64103 (143 hp / 187 Nm)	I-Alfa Romeo 164
I-AR67201 (143 hp / 187 Nm)	I-Alfa Romeo 155

Izinjini zesizukulwane sesibili ze-Alfa Romeo Twin Spark

Ngo-1996, isizukulwane sesibili sezinjini ze-Twin Spark saqala ukuvela ku-Alfa Romeo 155. Umklamo wabo wawuhluke kakhulu: kukhona i-cast-iron cylinder block, idrayivu yebhande lesikhathi, ikhanda le-aluminium lama-valve angu-16 kanye ne-inlet dephaser (kuzo zonke izinguqulo ngaphandle kwe-ECO). Ukuguqulwa okunomthamo we-1.8 no-2.0 amalitha kwakufakwe i-VLIM yokuguqula i-geometry yokungenisa, futhi yizinjini ezincane kuphela ze-1.4 ne-1.6 amalitha azenza ngaphandle kwayo, zine-manifold evamile.

Uhlelo lwe-Twin Spark luphinde lwashintsha kancane, amakhandlela amabili afanayo abekwe ngokulinganayo anikeze indawo ekhandlelani lamakhandlela amakhulu namancane, ingqikithi yawo eyayiphakathi nendawo. Lapho ushintshela ku-Euro 3, isistimu yokuthungela yabuyekezwa futhi kwavela amakhoyili angawodwana.

Umugqa wesibili wawunezinhlobo ezine zamayunithi amandla anevolumu engu-1.4, 1.6, 1.8 no-2.0 amalitha:

1.4 amalitha (1370 cm³ 82 × 64.9 mm)

I-AR38501 (103 hp / 124 Nm)
