VW faz recall do Novo Gol, Voyage, Gol G4, Polo hatch, Golf e Spacefox

A Volkswagen do Brasil anunciou, nesta segunda-feira (14), o recall dos modelos Gol G4, Polo hatch, Golf, Spacefox, Novo Gol e Voyage equipados com far�is de neblina de s�rie. Os propriet�rios dos ve�culos dever�o comparecer a uma concession�ria da marca para a verifica��o da lanterna traseira esquerda com luz de neblina e, se necess�rio, agendar a substitui��o da pe�a.

De acordo com a montadora, o poss�vel defeito est� na montagem da lanterna dos ve�culos equipados com farol de neblina de s�rie, nos quais a lente da luz de neblina � branca ao inv�s de vermelha, condi��o que pode confundir os motoristas que trafegam atr�s do ve�culo, causando a falsa impress�o que est� sendo realizada uma manobra em marcha a r�.

A convoca��o abrange 120.658 unidades. O servi�o � gratuito. Segundo a Volkswagen, os propriet�rios tamb�m ser�o avisados por cartas. D�vidas podem ser esclarecidas pelo telefone 0800 � 0195775 ou pelo site da empresa.

Consumo de �leo � 3� Parte

Se voc� ainda n�o leu a 1� parte e a 2� parte pode ser que fique em duvidas no texto seguinte.

Exames de Partes Complementares

Uma vez feita a prova da fuma�a e constatado que o motor est� efetivamente queimando �leo, passa-se � verifica��o individual das seis causas mencionadas anteriormente.

1 � Verifica��o da v�lvula de ventila��o do c�rter

Os motores mais antigos possu�am um sistema de ventila��o do c�rter composto de um tubo instalado lateralmente no motor, conhecido como tubo de respiro do c�rter.

Dessa maneira, a parcela de gases da combust�o que tinha passado para o c�rter era expelida diretamente � atmosfera atrav�s desse �tubo de respiro�.

Posteriormente, os fabricantes de motores, baseados em resultados de pesquisas sobre polui��o que demonstram que cerca de 30% da polui��o causadas pelos ve�culos a gasolina era proveniente dos gases que sa�am pelo tubo de respiro do c�rter e atendendo tamb�m �s leis vigentes em v�rios pa�ses sobre o controle de emiss�o de poluentes (principalmente mon�xido de carbono), desenvolveram o chamado �sistema de ventila��o fechado�, onde o tubo de respiro do c�rter � ligado diretamente ao sistema de admiss�o de ar do motor passando por uma v�lvula que controla o fluxo de gases.


V�lvula de ventila��o do c�rter

Dessa forma, os gases s�o reencaminhados � c�mara de combust�o, onde s�o queimados juntamente com a mistura ar/gasolina.

Esta v�lvula, depois de certo tempo de uso, pode apresentar-se inoperante devido ao ac�mulo de res�duos de �leo e carv�o que prendem-na em posi��o aberta.

Quando isso ocorre o �leo � aspirado diretamente do c�rter para o tubo de admiss�o e o consumo de �leo lubrificante � excessivo.

2 � Verifica��o do tubo de ventila��o do c�rter

Os tubos de respiro do c�rter, do tipo aberto, normalmente s�o instalados na lateral do motor, com suas extremidades inferiores localizadas ao n�vel do c�rter.

Devido a essa posi��o desprotegida, em determinados motores � comum ocorrer um c�mulo de impurezas ou amassamento da ponta, entupindo o mesmo.

Esse entupimento do tubo de respiro, mesmo que parcial, provocar� um aumento no consumo de �leo lubrificante, pois causar� um aumento na press�o interna do c�rter, ocasionando vazamentos por juntas e retentores e for�ando a subida do �leo para a c�mara de combust�o atrav�s dos an�is.

3 � Verifica��o de vazamentos nos superalimentadores ou turbo-compressores

Os retentores de �leo dos diversos tipos de superalimentadores podem falhar eventualmente. Todo o �leo que escapa dos retentores � queimado nas c�maras de combust�o.

Procure vazamentos de �leo nos turbo-compressores da seguinte maneira:

1 � Remova o tubo de ar que liga a unidade ao coletor de admiss�o.
2 � Verifique se h� �leo no tubo. Uma ligeira camada interna de �leo � normal, mas qualquer ac�mulo maior ou po�a de �leo indica que este atravessando as veda��es ou escapando do turbo�compressor atrav�s de alguma fenda na carca�a ou de uma junta com vazamento, etc.

Verifique tamb�m se o elemento do filtro de ar n�o est� obstru�do al�m do permitido.

Isto faz com que se forma uma grande depress�o na tubula��o de ar de admiss�o, for�ando uma aspira��o de �leo lubrificante pelo pr�prio turbo-compressor e conseq�entemente queima na c�mara de combust�o.

Verifica��o de perda de �leo atrav�s da junta de tampa de v�lvulas.

Alguns motores (como o motor Mercedes Benz 352, por exemplo) podem apresentar consumo de �leo pela junta da tampa de v�lvulas.


Tampa de v�lvulas e cabe�ote do motor 352

Isto ocorre porque nesses motores a tampa de v�lvulas, balancins e bicos injetores, cobre tamb�m a entrada do ar de admiss�o do motor, existindo uma parede interna que a divide em duas c�maras.

Se essa tampa estiver empenada ou instalada com junta impr�pria ou mal posicionada, passar� a existir comunica��o entre as duas c�maras e o �leo das v�lvulas e balancins ser� aspirado pela admiss�o e queimando na c�mara de combust�o.

Naza Rondo (Citra II) to spearhead Kia growth in Malaysia?

Naza Kia has had a stellar feedback on their recently introduced Rondo MPV, selling considerably well since its introduction in September this year.

"Sales results for the first two months of our Rondo introduction, more than 300 units, are in line with our objectives and confirm that more new customers are switching to Naza Kia products. I'm delighted to observe that this process is accelerating with each new model we introduce," commented SM Nasarudin SM Nasimuddin, CEO of Naza Group. "In this landmark year of change for Kia, the new Rondo and our other top models like the Optima, Sportage, Sorento and Spectra5 were both highly praised by members of the motoring media and our customers for having the best specifications for the prices offered in their respective segments. So far it looks like 2009 is already shaping up to be a great year for Kia in Malaysia."

Customer feedback thus far has gone beyond expectations, with many praising the Rondo's excellent fuel consumption which they can monitor thanks to the in-dash Trip Computer. Other features mentioned include the 6-speaker audio system with steering wheel mounted remote control*, automatic air-conditioning*, roof rack, folding door mirrors and attractive alloy wheels.

Journalists too, have come forward with nothing but praise for the Rondo. "Going uphill is again another starter for us as the Rondo, with seven adults, just cruised along without straining its engine. Seriously, it was such a refreshing experience as we never felt a Korean engine this good and this smooth," reported motoring news editor Hezeri Samsuri. "Sound insulation is good and on par with Japanese sedans in its price category. Bumps and holes are muted well, and so does the engine noise. The Rondo does have a good dashboard layout and the material used is also durable and does not look or feel cheap, which speaks of the improvement in quality noted over its predecessor.

Nissan UP_SHIFT_its Z_car to 370z for 2009

Click on images to enlargeWhile our fellow Malaysian sportscar enthusiasts are busy lapping up used Nissan 350Zs in reconditioned form with JDM-specs (grey AP imports), Nissan Motor Co. has just revealed the latest incarnation of its iconic Z-car for 2009 model year.

Unlike the dramatic transformation of the R34 Skyline GT-R to R35 GT-R, Nissan seemed to have taken the evolutionary path for its new Z-car, with much of the 350Z' basic shape retained. In fact, I initially reckoned the all-new Z of being like what Audi has done for its A4 transition from B6 to B7. However, dimensions-wise, the new 370Z has actually defied the usual convention of a successor model outgrowing the older model.




Case in point, the new Z's wheelbase is actually about 100mm shorter than the 350Z, compacted by moving the rear axle forward on Nissan's FM platform. In tandem, the overall length of the new Z has shrunken by about 68mm. Thankfully, both width and track have been increased by 33mm and 55mm respectively. In line with this wider-profiled sportier intent, the new 370Z coupe also sits lower by 75mm.



I suppose the real deal with the new 370Z lies beneath its metal sheets, especially with the now upsized VQ-series V6 engine displacing a larger 3.7-litre. Nissan's VQ37VHR engine with VVEL (Variable Valve Event and Lift) is rated at 332 hp @ 7,000 rpm and 366 Nm of torque @ 5,200 rpm, compared with the previous 3.5-litre V6's 306 hp @ 6,800 rpm and 363 Nm of torque @ 4,800 rpm. Approximately 35% of the engine parts are new versus the previous motor. Along with its larger displacement, the new engine is claimed to give better power delivery all the way to the 7,500 rpm redline, improved low-end power and more high-end torque. The new 370Z has also shed 46 kg over the model it replaces, with Nissan engineers revising the coupe's body structure and improving front body torsional rigidity by up to 30 percent.

With higher power output, a lighter body and a new 7-speed automatic transmission or a close-ratio 6-speed manual, the new 370Z should be significantly quicker than the outgoing model, but no official performance figures are available at the time of writing. A more compact lengthwise dimension plus a wider, lower squat should improve agility and handling.







In overview, Nissan revived its iconic Z-car lineage with their reinvented 2002 model. Now - 6 years later - for the successor Z, nearly every piece and component has been rethought or redesigned. With greater use of lightweight body materials (the bonnet is all-aluminium), new engine with more horsepower and improved fuel efficiency, a new 7-speed automatic transmission with paddle shifters - or the world's first synchronized downshift rev matching system for the 6-speed manual - and a reworked higher-quality interior, Nissan seemed destined for greater presence - along with the monstrous R35 GT-R - in the sportscar arena.
