The first 2007 EPA-certified Caterpillar engine with ACERT Technology is the C7, a popular choice with customers who operate medium-duty vocational and delivery trucks. It will be in full production by January 1, 2007. The C7 is also widely used in a variety of other medium duty applications, including school buses, emergency vehicles and recreational vehicles.

ACERT Technology relies on four basic systems to lower emissions:

  • Air management;
  • Precision combustion;
  • Advanced electronics; and
  • After-treatment

These four systems work to decrease particulate matter, oxides of nitrogen and hydrocarbon emissions while preserving the engine’s reliability and durability, which keep owning and operating costs low.

The Caterpillar C7 engine features an enhanced version of ACERT Technology that allows it to comply with the 2007 EPA regulations without sacrificing reliability, durability or fuel economy.

The 2007 ACERT C7s feature power ratings from 190 hp to 300 hp (142 kW to 224 kW) @ 2,200 rpm for truck and bus applications, and 300 hp to 350 hp (224 kW to 261 kW) @ 2,400 rpm for RV and fire truck applications. Torque ranges from 520 lb-ft to 860 lb-ft (705 Nm to 1,166 Nm) @ 1440 rpm.

The 2007 C7 is a 7.2-liter, in-line 6 engine that features a variable nozzle turbo and a common rail fuel system that helps optimize performance and increase fuel economy by up to 4%. The 2007 aftertreatment system uses cooled exhaust gas recirculation (CEGR) and Clean Gas Induction (CGI). (See diagram at right.) The diesel particulate filter (DPF) is self-regenerating.

只要是双声道的耳机，哪怕是地摊货，都能听出比CD更牛A的音质~不信？你试试~~
西小西强烈推荐~
下面这个音频是一段人头录音的试听，内容是虚拟理发，不是鬼故事，大家放心听~~

备用地址：

我第一次接触人头录音是在08年下半年去上海科技馆的时候，但当时并不知道这是人头录音技术。上海科技馆科技之光的鬼屋，听鬼故事的，真的很逼真啊，我反正没敢听完~~怕怕~
这篇博客3月1日写过的，但是考虑到沉底咯，还有连接失效咯，所以今天重发哈子~
还有目前来讲，只有verycd有些人头录音的资源，大家直接去verycd下载就可以咯~
其他资源基本找不到，大家别费神啦，我费的够多的啦~鬼故事我在网上找好久啦，根本找不到~

学习了tracert命令~
利用tracert命令你可以一步一步地弄清楚网站访问是怎么样一回事~
感觉像坐车一样，一站一站的，呵呵~好玩~
我用这个命令来找空间商的老根的，嘿嘿~
今天在wordpress.org.cn看到的一篇强贴，讲的就是这个~
1. tracert扫盲

开始 运行 输入 CMD
tracert+IP地址/域名


下面我们就来示范怎么Tracert主机，我们以SOHU为目标吧！

C:\>tracert www.sohu.com

Trace complete.

下面我就解释一下上面的语句：

Tracing route to cachechengdu2.sohu.com [221.236.12.211]

因为SOHU是大型网站，在访问的时候SOHU公司对网站的负载和路由进行了优化，这样大家访问速度就不会慢。在我们连接SOHU主机的时候根据我们的路由情况，我们被自动分配到了cachechengdu这个地方。相信不同地域的 朋友tracert的时候也是不一样的结果的，我的位置在广东深圳。

1 <10 ms <10 ms <10 ms 202.104.147.129

1 就是第一HOPS，就是你的PC访问目标主机要经过的第一路由点，因为这个是公司内部的网关，所以速度非常快 ！当然，你可以通过whois查询其信息：

IP Location: China – Guangdong – Shenzhen – Shenzhen-longmaixinxi Inforamation Co.ltd
Reverse IP: No websites hosted using this IP address

IP指向的地址可以看到的，和我的实际地址一样，中国-广东-深圳，这里也是一致的 China – Guangdong – Shenzhen ，后面就是我工作的公司… ^_^….后面还有好多好多信息就自己看啦，一般看到的都是 CHINANET之类的，无非就是电信，移动，铁通什么的，虽然是E文，但是也好明白！

2 <10 ms <10 ms <10 ms 202.104.147.1

第二HOPS，是我们公司到广东电信节点的CISCO7600…不多说， 同上

3 <10 ms <10 ms * 59.40.49.5

第三HOPS，到电信的主干网络啦…去 whois…信息如下

IP Location: China – Beijing – Beijing – Chinanet Guangdong Province Network

然后数据在广东 电信的网络里面兜了几个圈子，用掉几个HOPS一直到

7 10 ms 10 ms <10 ms 202.97.43.145

whois的信息是
IP Location: China – Chinanet Backbone Network
骨干网络里啦….

8 40 ms 40 ms 40 ms 202.97.43.154

HOPS 8 也是在骨干里面..

9 40 ms 40 ms 40 ms 222.213.1.190
whois信息
IP Location: China – Sichuan – Sichuan – Chinanet Sichuan Province Network
汗，居然到四川了…..
10 50 ms 40 ms 41 ms 222.211.63.22
11 40 ms 40 ms 30 ms 221.236.8.4
四川兜了好几圈….到了头了….

12 40 ms 40 ms 40 ms 221.236.12.211

最后在四川安家了…
IP Location: China – Sichuan – Sichuan – Chinanet Sichuan Province Network

汗….SOHU的镜像在四川…..cachechengdu前面看到的东东就是 成都！

有点晕晕……

12就是HOPS数量，就是说我的电脑到SOHU的主机一共经过了12个路由节点。

PING值稳定在30，HOPS数量小于15，既然是12！真是极品主机啊，SOHU真….
