发动机噪音大的原因有以下几种:
1、汽车发动机的声音如果是从排气管中出来,极有可能是排气管破裂导致,更换即可
2、在发动机高速运行过程中发出刺耳的声音,可能是火花塞老化或者由于有污物堵塞所致,更换即可
3、若是发动机的声音十分低沉,有可能是油量耗尽,及时填补即可
4、若果发动机的声音随最大功率转速改变而改变,则有可能是发动机的轴承损坏,更换即可
5、若是发动机声音类似金属碰撞,则有可能是发动机气缸阀门出现问题,需专业维修人员修理
6、若出现的声音是一种轰鸣,类似爆发的声音,请检查发动机消音器是否损坏,更换即可

发动机舱清洁
1、打开发动机罩,然后把分电器、蓄电池和制动油壶用塑料布遮盖
2、打开水枪喷洗发动机舱内,对发动机上的灰尘泥土进行冲刷。此时一定要小心,不要用水枪直接冲到发动机内
3、用水枪冲洗前挡风玻璃下面的导风口
4、用绒布蘸水清洁水箱和散热片以及冷气冷凝器上的灰尘、树叶等杂物。清洗时注意由内到外
5、用水枪小心清洗发动机舱内侧的支撑条和其上的污物
6、用空气喷枪或者气吹喷除发动机舱火花塞内的灰粒。最后擦干各部位即可
噪音分胎噪,风噪,发动机噪音,你这么一说全占上了。风噪是随速度提高而增强,你说的8000公里不符合逻辑,胎噪的问题,有可能,但是新车时候噪音很小,但是现在噪音大应该不是胎噪吧。汽车开的公里数长了会产生积碳,这是造成发动机噪声的一个原因-爆震,但是你的车才开了8000公里应该不会啊。
东风日产轩逸是一款定位在天籁与颐达之间的产品,是一款拥有优美造型、宽敞空间的全新中级轿车,也是日产进军中级轿车市场的主力车型。“轩逸”是nissan开发的一款全球全新车型,英文名为bluebirdsylphy
“sylphy”这个单词来自于英文“风之精灵”,这款车已经于去年12月21日在日本本土推出。目前,东风日产推出的轩逸是第10代蓝鸟车型,是风神蓝鸟的替代产品,并为其取了一个优雅的中文名称—“轩逸”。
轩逸在内饰方面完全继承了日系车精湛的做工,米色系及桃木装饰条营造出温馨的家庭氛围。中控台上,信息显示、空调、影音、空气净化系统以及通讯系统齐全,所有功能键序列组合不仅一目了然,而且也与车内简约的设计风格相匹配。轩逸仪表板与中控台和变速杆被设计得非常有整体感。仪表板采用白色背板搭配橙色指针和灯光;中控台的布局很整齐,各种功能键的按钮都很大,便于操作;空调采用旋钮式,便于与音响按钮进行区分;方向盘为真皮和实木搭配,用料和做工都很显档次。此外,轩逸贝壳形的座椅也依据人体设计,将乘员的重量按比例分配在座椅的各个支撑部位,让全车的乘员都获得舒适的乘坐感。坐进车内,不难发现,轩逸明显承袭天籁的内饰布局,即使等级与配备没有后者那么高级,设计师也努力向科技感与高级感靠拢。在前排左侧,驾驶者有一种“被控制界面包围”的乘坐感受,而副驾驶座的乘客则获得了开放感。通过多处采用的s曲线如将中控台设计成s形,形成了将驾驶员包围起来的空间,从而造就了以驾驶者为导向的前排布局。这一形式同样也被日产应用到旗舰车型风雅上。
这是窗户上的密封条胶皮老化的原因,去保养得地方检察检查吧。
