BMW N52保养分享:六气缸的倔强,自然吸气的坚持,内燃机的浪漫

如果你是货真价实的Bimmer,你一定有听说过N52的大名。这具一代铭机,被广泛运用在BMW车款中,从2005年服役至2015年。

N52的出现,是为了取代另一部经典引擎:M54。N52在车友的眼中,大多获得“太敏感”,“太多电子”的负名。这期,就然我们为N52辩护,让大家了解这部BMW家族中六缸自然进气引擎的绝唱,也是至今为止最佳的自然进气六七杠引擎。

N52的背景故事

BMW的六气缸引擎,可谓是汽车行业内的标杆。细腻的运转品质,顺滑却浑厚的扭力输出,以及澎湃的动力。毕竟,BMW可是从1930年代就一头栽入六缸引擎的研发与制造。十年铸一剑,宝马铸造六气缸引擎已经接近100年了!

真正和汽车世界挂钩的BMW六气缸引擎,可追朔至1960年代,至今已经发展了7代。从旧至新,他们的代号分别为M30,M20,M50,M52,M54以及N52,最新的为N53。

N53过后,BMW就放弃了自然进气引擎的坚持,进入了涡轮增压时代。属于二十一世纪二十世代的N64,N55以及B58引擎,就此诞生。

回到正题,本文讨论的N52引擎,比起前代M54的最大差异,就是- 缸体运用了更为轻量化的镁铝合金(Magnesium-Aluminium Alloy)制造。

为了得到更好的动力,以及更经济的油耗,N52也配备了BMW引以为傲的Double VANOS /Valvetronic持续可变气门升程技术。 N52的进气歧管也具有可变进气道DISA的设置,以提供更好的扭力与更好的油门反应。

运用N52的主要车款,为2000中期至2010年中期的E90 3系,E60 & F10 5系,以及E65 7系列。大部分的X系SUV车款,也搭载了N52引擎。

F10 BMW 5 Series前期款,大多采用这具经典引擎

根据市场的需求,N52引擎又被细分成3种排气量:2.3公升,3.5公升以及3.0公升版本,动力输出介于177PS/230Nm272PS/315Nm之间。

N52的保养与维修

和其他的引擎一样,N52也需要定时保养才能保持在最佳的运行状态。

N52一共有两种引擎盖款式,分别为黑盖以及银盖

大部分时候,许多车主都不知道如何对这部引擎进行预防性保养。而就是因为没有进行预防性保养,才会在后期导致许多问题,甚至导致引擎故障等等。不过,这并不代表这具引擎的可靠性很低。里程累积至六位数的N52,大有例子。

以下为N52的预防性保养事项:

BMW N52 保养与维修事项
零件 症状  保养里程
(油格胶条)
Oil filter housing gasket
引擎周围与皮带出现漏油症状 100k km 进行检查与更换

(阀盖垫片)

Valve cover gasket 

引擎侧边出现漏油症状 100k km 进行检查与更换
(油冷)Oil cooler 水箱水会开始与引擎润滑油混在一起 110k km 进行检查与更换
(水箱候)
Coolant flange
水箱水/冷却液漏出,引擎过热 在110k km的时候把原有的塑料制零件更换成改进铁质版本
(气门正式电磁阀)
Vanos solenoids
引擎乏力/怠速不稳 出现症状时候更换/在更换Headgasket时候顺便更换

能够根据上述的列表保养N52的话,N52绝对能够可靠的伺候您。最重要的是,千万别为了便宜使用第三方零件。BMW的引擎,用回BMW原厂部件最为可靠。

看似小小的油格胶条,会带来大大的麻烦。胶条失效后,引擎会漏油,渗出的润滑油会漏至皮带,导致皮带打滑。断裂的胶条,也会被带入引擎内部,导致更大的麻烦。

除此之外,我们也建议在8000公里左右就为N52更换全合成机油,Fully Synthetic Engine Oil。值得一提的是,BMW在某些国家建议使用5W-30的机油,以及10,000公里的保养间隔里程,不过我们接触的BMW维修专家,大部分都建议使用5W-40的机油,以及更短的保养间隔里程,以让引擎有着更持久的耐用度。

当引擎周围出现油渍时,就代表必须更换阀盖垫片Head Cover Gasket了

用在BMW身上的ZF 6速/8速自排变速箱内在的变速箱润滑油ATF以及润滑油格栅ATF Filter,也是需要定期保养更换的事项。这两具变速箱,也是以耐用著名。

结论

大部分Bimmer听到N52的名号,都会再三考虑是否入手。N52,其实是一副非常优秀的自然吸气六气缸引擎。你可以说它是BMW累积了超过50年的经验后,把所有的专长给砸入的集大成之作,也是宝马家族里自然吸气六气缸引擎的绝唱。兼顾效率,性能,也充满了六缸的灵魂,这些都是让我们怀念经典宝马的主要元素。

想要体验经典宝马,却不想开太旧的车款?N52引擎系列,就能让您找回属于那个辉煌时代的BMW。
