来自主题: Automobile版 - Re: Timing chains/Timing belts
timing chain虽然不用换,但是chain工作时候需要润滑,而belt不需要润滑,
所以timing chain还有一个及其复杂的润滑系统,10万以上的时候会导致漏油,
几乎所有用timing chain的车都漏油,从发腊力,奔驰,奥迪,到尼桑,这些
用chain的车老了没有一辆不漏油的。而且,chain的tensioner常常是塑料做的,
历程高了导致断裂,会发出比较大的噪声。
所以,现在除了那些做不了timing belt的车厂,比如nissan,已经没有什么车厂
出的新发动机还在用timing chain的

你找的车铺啥都不懂,换地方吧
toyota新的2az-fe发动机timing chain tensioner装在发动机外面,不是里面,
你这个问题是chain tensioner assembly No 1坏了,造成上timing chain skip
死机,下timing chain是没有问题的。
解决问题很简单,拆开上timing cover,拧松前后2个camshaft sprocket,重新
校对timing chain上的mark,对齐后拧死camshaft sprocket,然后装上新的No1
chain tensioner.就行了。
你找的人啥都不懂,不行去dealer吧,就告诉它们No 1 chain tensioner坏了,
dealer估计一听就知道啥回事情了

我的理解:
Monte Carlo method是一般意义的随机模拟方法,它首先得抽样,再做统计计算,估
计期望。
根据抽样方式的不同,可以对monte carlo分类。如,常见的是简单随机抽样,也即iid
方式,这也就是大众理解的monte carlo方法,如用来计算PI值的积分模拟方法。当不
是iid方式,也就是说样本不独立,同分布也难定,那种类就很多,较简单的是,抽样
是对Markov Chain 特征的总体,这些样本在较短时间内不独立,但充分长时间内的样
本之间是独立的,当然前提条件是这个Markov Chain 是稳态的,也即能达到统计物理
上的平衡。对Markov Chain 抽样不能用简单的类似求PI值一样的方式,而常采用
Metropolis抽样方式,首先模拟总体生成一个满足要求的Markov Chain,再对这个链进
行抽样,再做统计计算,当然还得先对这些来自Markov Chain的样本进行关联性分析。
这种Monte Carlo方法就是Markov Chain Monte Carlo。
Markov Chain中的每个微观态只和前一个态概率关联,以其他历史态独立,

Stanza is earlier version of Altima, it should be a non interferance engine.
it looks your miliage is wrong.
Do you know which timing chain was broken? upper chain or lower chain? You
have to check this first.
Upper chain is easy to fix, but lower chain is very hard, Stanza has upper and
lower oil pan, to remove lower chain, you need first remove oil pump assembly,
which is on crankshaft---> this means you have to remove the lower oil pan
first.
But lower oil pan in Stanza, used as engine suppor

来自主题: Automobile版 - 请教timing belt, timing chain
Belt vs Chain:
成本:chain比belt高不少
噪音:belt比chain低很多
性能:belt的timing比chain要准确的多,所以belt的performance要高
另外,belt虽然定期更换,但是在service life里面performance是不变的;而
chain的performance随着使用是会不断下降的。
寿命:belt必须定期换,不换会出大问题
chain并不是不需要换,只是不换也不会出现大问题而已。

After driving 15 miles in 22" inches of falling snow on unplowed roads, I
finally caved and am resorting to these. The reviews seem good for the
purpose at hand. And definitely worth the piece of mind of not skidding/

the snow too, so I figured some could use some of these themselves.

车型: Altima 2.4, 12k mile
问题: oil pump o ring leakage, upper timing chain tension fail(参见NISSAN
technical bulletin TB)
现象: idel时有咔咔声, 车右侧严重漏油
解决方案:更换o-ring(这个o-ring是典型的bad design, 5块钱的parts, 却要1000块的人
工),顺便更换timing chain.
parts:from parts.com
1)timing chain upper, lower 2 根
2)timing chain guide upper/其实跟upper tension是一体的,咔咔声是因为NISSAN设计
错误(参见nissan TB), 新设计的有2个螺丝
3)lower timing chain guide, slack side, tension 不用换, tension side
也不用换,这个guide是胶木的,可惜order时买错了,买成了tension side, 问了当地店都

(以前发过,加在了屋里八哥的后面,现在专门提出来供参考)
Bead chain eye leech,功效和屋里八哥差不多,甚至更“通杀”!
其变化就是
1:用bead chain eye代替bead head;
2:钩可以更小一些,例如#10-14;
3:视鱼种、水域、季节看看是否加铅丝;
4:不需要使用颈羽缠绕出body毛毛;
以下是示意图,过程和woolly bugger差不多一样,在此不再重复。
说一下材料的名称:各种颜色的Marabou毛毛(软羽毛代替也行),各种颜色的Chenille(一块多一包,注意需要买small size的,med size太粗),bead chain(这个很好找,大小合适就行)

。不要说光去考个第一,其他的都是傻逼。
这supply chain也是同样道理。我这次回去遇见的,基本面都是两种同学:销售,安全
。我举个简单的例子哈:有个东西假定说1万吨。那么,我便宜100块,就赚了100万。
我多卖100块,就赚了100万。你考去学商学院的那种supply chain,什么最优化,在中
国全鸡巴骗人的。你说quant牛逼吧?我同学的公司,在nyc有office的。结果他们就一

这是什么意思哪?你回去国内看看就懂了。就是在饭桌上,在会所里,对男人哪有男人
的办法。一般说还很容易。对女人哪,就要有对女人的办法了。一般说就很难。但是很
难的事情,做成了回报就大。很容易的事情,对你容易,对别人也容易。所以说哪,进

正确描述Markov Chain应该是用State probabilities和transition probabilites.
你说的dropping and blocking probability,可能是通过Markov Chain算出来的实际
参数。
打个部分, 有一个很简单的Markov Chain, 只有2个状态: A和B.
它一共有以下变量:
state probabilities: SA, SB.表明任何一个适合系统处于A或B的概率。
transition probabilities:
(1) PAB:由A向B转变的概率。
(2)PAA:停留在A的概率。
(3)PBA:由B向A转变的概率。
(4)PBB:停留在B的概率.
系统方程:
SA+SB=1;
SA*PAB+SB*PBB=SB;
SB*PBA+SA*PAA=SA;
PAB+PAA=1;
PBA+PBB=1;
如果事先已经知道SA,SB,PAB,PBA,PAA,PBB这些参数的一些值,就很容易通过以上系统
方程算出所有参数的数值。
对于比较复杂的Markov Chain,得出的系统方程可能很复杂,可以用Matla

看中一辆二手车,2001Toyota Corolla 100K Miles(标题不小心写错了) ,车主说Timing chain不同于
Timing belt是终身不需要换的,请问买回来后我还需要自己掏钱换Timing chain吗?
如果还需要我自己换的话,我就不买了。加上换Timing chain的钱,价格就太高了。

来自主题: Automobile版 - 请教timing belt, timing chain
有些车用timing belt,有些用timing chain
感觉belt 100k左右必须要还(各车还不一定一样)
timing chain好像不用换,省钱省时
多数车是belt
好像nissan, dodge truck都是chain。不知道对不对
有没有什么其它简单区分方法?

It's not gonna work for you to try SAP because of no experience. Developing
SAP
applications not only require your knowledge on ABAP (programming language),
but also the company's supply chain process that you work on...so i will
suggest that you have to choose to either try IT or supply chain as for now.
If you choose supply chain and have an opportunity to work on that for a
company, later you can help them develop their SAP programs.
Good luck!
