:) Hej !
Någon här som kan berätta lite mera i detalj kring 1.8 TSI ( 160 Hk ) motorn ?
Kända bekymmer ?
Svaga punkter / problem ?
Törstig ?
Mellan vilka år tillverkades den ?
Skiljer det något på motorn mellan årsmodellerna ?
Hur är den i jämförelse med den äldre 1.8T , 150 Hk ( 20 Ventils. ) motorn ?
:confused:
The EA888 engines are a family of four cylinder engines that are currently in use across the Volkswagen Group. The EA888 family is an Audi-designed unit that features some of the latest engine technology such as direct fuel injection, sintered camshaft lobes, thin-walled engine block, variable valve timing and lift for intake and exhaust valves, downstream oxygen sensors, turbocharger integrated into cylinder head, exhaust gas recirculation and cooling, distributorless coil-on-plug ignition, lightweight engine internals, slide valve thermostat (some variants), and the addition of port fuel injection to aid low load fuel consumption and cold start emissions. The port fuel injection also aides in reducing the potential carbon deposits that can occur in direct injected engines. Volkswagen has made numerous enhancements to their engine designs such as the positive crankcase ventilation, repositioning injectors and more to lessen the potential that carbon deposits accumulate on intake valves. Currently, the EA888 engine is available in two sizes: 1.8T and 2.0T.

:) Intressant läsning Marcus, men tyvärr svarar det inte på mina frågor. :confused:
Motorn ska stor sett vara samma som 2.0:an med kamkedja
Jag tycker det i allra högsta grad svarar på detta :)
Någon här som kan berätta lite mera i detalj kring 1.8 TSI ( 160 Hk ) motorn ?
Som Andreas skriver är det i stort sett samma motor som den vanliga 2,0 TSI ur EA888 familjen.
Föresten, BobCat, du kör väl en Golf Alltrack 1,8 TSI? 1,8 TSI 180 i din Golf Alltrack är från samma motorfamilj EA888 som 1,8 TSI 160 i bland annat Passat generation 6 och 7 samt Golf generation 6.
Föresten, du kör väl en Golf Alltrack 1,8 TSI ?
1,8 TSI 180 i din Golf Alltrack är från samma motorfamilj EA888 som 1,8 TSI 160 Joo, jag vet att 1.8 TSI motorn i familjens Golf-7 Alltrack är en EA-888 Gen-3
Men hur ser man skillnad på de 2 andra generationerna och mellan vilka år fanns de ?
Vad skiljer dem åt i detalj ?

Tyvärr är det bara den senaste Generation-3 av EA888 motorn som tas upp.
Hade velat få mera kött på benen om Gen-1 och Gen-2 :confused:
