Boxermotor

[porschepipo]

De zuiger en de bussen slijten zeker. Het uitslijten wordt gecompenseerd door de zuigerveren, waardoor een goede afdichting gegarandeerd blijft zolang de veren niet versleten zijn want deze slijten natuurlijk heeft meest.

ah, ok

maar de zuiger kan toch maar beginnen slijten als de zuigerveren even groot zijn?

Tegen dan heb je de zuigerveren al zeker moeten vervangen ivm de smering.

Subaru is celebrating the 40th anniversary of the introduction of the "boxer" or horizontally opposed engine to its passenger car line-up this year.

It was in 1966 that Fuji Heavy Industries introduced the Subaru 1000, a four door sedan with a one litre, four cylinder boxer motor and front wheel drive

The technology made Subaru stand out from the other Japanese cars of that time, most of which were rear wheel drive, with conventional in-line engines.

Initially the flat four motor was considered to be a bit "quirky", but it paved the way for the symmetrical All Wheel Drive system that is the cornerstone of every new sold in New Zealand today.

By 1969, development of the engine saw it grow to 1100 cc when it was introduced in the then new Subaru FF1 car. With a north/south gearbox behind the engine, the front wheel drive Subarus of their day had balanced weight distribution across the car and equal length driveshafts.

The motor in overhead valve form was now being fitted to all of Subaru's larger front wheel drive vehicles and in 1971 it became a fixture under the bonnet of the first Leone, a name plate which was to survive through successive models until 1989.

In 1972 Subaru introduced a 1400cc Leone station wagon with four wheel drive, becoming the first passenger car manufacturer to use a four wheel drive transmission, several years before Audi began "quattroing" its cars. Until 1972 4WD had only been used in commercial vehicles, designed specifically for off road use.

With the introduction of 4WD, the symmetrical layout of the boxer engined powertrain became even more important. There was no need for power take offs, unequal length [COLOR=blue! important][COLOR=blue! important]drive [COLOR=blue! important]shafts[/COLOR][/COLOR][/COLOR] and unequal weight distribution in the engine bay.

The cars had a symmetrical, natural, neutral balance, with near equal weight distribution side to side and front to rear. Subaru's reputation for producing a good handling car was enhanced by the lower centre of gravity of the boxer engine, compared to inline or transverse engines and the road holding was improved by the All Wheel Drive as Subaru re-named its 4WD system to distance itself from the other 4WD copy cats in the car manufacturing world in the 1990s.

By 1979 Subaru had a 1.8 litre boxer motor powering the top models of the Leone range and was beginning to gain class victories on some of the world's toughest rallies, notably the Kenyan Safari. In 1983 the late Possum Bourne gave Subaru's boxer motor its first New Zealand success, winning the Group A class on that year's World Championship, Rally of New Zealand. Continual development of the engine saw it acquire single overhead camshaft cylinder heads by the mid 1980s and turbo charging for the first time on 1985 models.

In 1987 FHI developed a 2.7 litre, six cylinder version of the engine which was fitted to the Alycone coupe. Perhaps the most significant milestone in the motor's constant upgrading came in 1989 with the introduction of the first Legacy, with the top of the range Legacy RS unveiled with a two litre double overhead camshaft engine and turbo charging. This was the foundation on which the company's world wide rallying success has been built on ever since. The introduction of the Legacy RS was complete with the establishment of a 100,000 kms World Speed Record at a tyre testing track at Arizona.
In 1991 the futuristic SVX gained a 3.3 litre, six cylinder version of the flat four engine. 1993 saw the introduction of the smaller Impreza range, which turned Subaru's rallying efforts into success with a more efficient intercooler system for what was to become the iconic WRX model.

Just before it bowed out, the Legacy RS gained Subaru its first WRC victory on the 1993 Rally of New Zealand with Colin McRae at the wheel. In 1993 a station wagon version of the Legacy GT set a World Speed record for wagons and broke it again in 1998. When Subaru introduced the crossover SUV Forester in 1996 it successfully completed a 24 hour speed record attempt at Indianapolis speedway, in its turbocharged form. Subaru was leaving no stone un-turned in its efforts to prove its products and the boxer engine was not only fast, but also reliable. In 1995, 96 and 1997, Subaru won the World Rally Manufacturer's Championship, with the Impreza WRX, the first time a Japanese manufacturer had accomplished the feat for three successive years. And McRae, the late Richard Burns and Petter Solberg have won World Rally Driver's Championships with the two litre turbocharged boxer engine in '95, 2001 and 2003 respectively.

Closer to home Bourne won the NZ title in 1991 and the Australian championship for seven successive years from 1996 to 2002 in a boxer engined Impreza WRX.
Subaru has also gained NZ Rally Championship titles through the efforts of Joe McAndrew, Bruce Herbert, Chris West and Richard Mason a total of eight times and won the standard production Group N class just as many times, all with boxer engine power!

The latest six cylinder version, or H6 as it has been called, of the boxer motor was introduced in the Outback in 2000 and in the Legacy range in 2003, as a three litre with quad camshafts. The Legacy and Impreza have won numerous Car of the Year awards in the last decade, thanks to the unique characteristics of the horizontally opposed motor under the bonnet. The WRX has earned a deserved reputation as providing the best value for money performance car of the modern era.
In its most recent 2.5 litre turbo charged form as fitted to the 2006 model Impreza WRX and Forester XT, the Subaru boxer engine was judged the best two to 2.5 litre motor in the world this year by an international panel of motoring journalists, thanks to its better torque and still outstanding performance, while meeting all the latest stringent emission control regulations.

Subaru is planning to stick with its boxer engines as the basis of its future models and is currently in the final stages of developing a diesel boxer motor to meet market demand in Europe where over 50 percent of all new cars are now diesel powered.

ah, ok

maar de zuiger kan toch maar beginnen slijten als de zuigerveren even groot zijn?

Tegen dan heb je de zuigerveren al zeker moeten vervangen ivm de smering.

Tis moeilijk uit te leggen, de zuiger zal minder slijten dan dan veren. maar de zuiger heeft maar een zeer kleine speling in de bus, anders gaat hij zeker kantelen. Maar de slijtage zal minimaal zijn.
Over het algemeen hoeven ook enkel de zuigerveren en liefst ook de bussen vervangen te worden bij een revisie.

Als er geen bussen zijn, moeten deze uitgeboord worden en dan heb je overmaatzuigers nodig!!

I see, bedankt voor de uitleg.

Cilinderbussen vervangen bij een boxermotor is wrs ook niet evident,
aangezien je die langs de zijkanten moet vervangen en alles dan in de weg zit.

bij alfa neem je het ganze blokje weg, gemakkelijker dan liggen te klooien in veel te kleine ruimtes

alfa 33 16v boxer 1.7 16v 137pk

zelf jaren meegereden.Enorm plezierig,aggressief,

[ErikF]

Verbruiken boxermotoren meer, en zo ja, omdat....

-dit inherent is aan de configuratie
-er simpelweg meer viercilindermotoren zijn uitgebracht en die technologie meer bestudeerd is op zuinigheid
-omdat ze bij Subaru vier wielen moeten aandrijven en bij Porsche altijd in sportkarren liggen

De subaru boxerdiesel is een krachtpatser en enorm zuinig.

van 90 tot 95/96 gemaakt 16v versie

de orginele boxer stamt uit de jaren 70



in zowel sud, 33 als 145 gebruikt

[Gast]

Ik heb vroeger nog met een Alfa 33 met een 1.4 boxermotor gereden. Redelijk vinnig wagentje voor een 1.4 maar totaal onbetrouwbaar. Ik heb er vrijwel alles aan moeten vervangen en uiteindelijk is de motor aan hoge snelheid op de snelweg vastgelopen. Heb hem toen maar verkocht aan een bende Roemenen die dachten dat ze er nog wat van konden maken

[Gast]

dat Alfa blok
en zo klein

ik heb 3 "33's" gehad 1.3 en twee 16v's waaronder een p4(4x4)

230 000km met men 16v blok...welke gevoelig was voor olie enz


die 8v boxermotoren zijn oersterk...

er is eentje in holland met 700.000 op de teller
