贾新光:五大原因导致 大众大意失荆州
——摘自搜狐网(http://auto.sohu.com)
2002年6月2日大众汽车集团董事会董事、大众汽车集团亚太区董事比西霍夫博士在接受记者采访时表现出一种很强烈的自信:对于其他的竞争对手,与之相比,我们相信我们对中国有着更多更深的了解,这是我们自信和能够成功的原因。他说,其实汽车市场的价格战早在2000年就已经开始,全球如此,中国也不例外。虽然大众一直希望能够在中国汽车市场拿到50%的份额,但也早就表示过,不会通过加入价格战的方式去拿份额。虽然大幅降价在短时间内可以使公司的市场份额上升,但从长期角度看,不会给企业带来可持续发展。“我想强调的是,大众不会用钱来买市场份额。”“大众一直在强调质量,我们说的这种质量中包含产品的、服务的、业务的各个方面,在这个问题上,我们执行的是全球统一标准。在价格问题上,中国市场与全球市场一样,我们执行的也是全球统一标准。我们希望让那些凡是购买了大众产品的用户感到物有所值。”
比希霍夫指出,大众汽车决心捍卫其在中国市场的领先地位。根据1999年制定的5年投资计划,大众汽车集团每年在中国投资5-6亿欧元。到2007年大众汽车集团计划在中国销售100万辆汽车。
上海大众德方副总经理曼弗雷德·海因彻不无骄傲地说:新来者若想分庭抗礼,会颇费时日。今后大众仍然要在中国坚持生产,这是长远的战略决策。海因彻表示,“我们在合资企业中的合伙关系目前相当不错”,“我们已经有了一个相当好的基础,我们希望能够把合资企业继续办下去。”“日本人和美国人都犯了错误,因为他们并不情愿向中国市场投资。”“我们有自己的供应商,我们解决了质量问题。现在,大众可以追求高产量了。”
2002年,上海大众和一汽大众共生产轿车47.06万辆,占中国轿车产量的43.14%(上一年为51.76%)。2...

| Cam Shaft |

The camshaft is driven by the
crankshaft by one of three methods:
- Gear drive
- Sprockets and timing chain
- Sprockets and timing belt

Ford Motor Corporation.
- Check the camshaft for:
- a plugged oil feed,
- the correct cam lift or
- any broken or severely
worn areas.
- Check each lobe and journal
for:
- scoring,
- scuffing,
- fractured surface,
- pitting,
- and signs of abnormal
wear.

Steel camshaft and roller
followers in good condition.

Badly burned and worn
camshaft bearing bores.
Normal lobe wear is a pattern
slightly off center with a wider wear pattern at the
nose than at the heel. The off-center wear is a
result of the slight taper of the lobe used in
conjunction with the convex shape of the lifter to
rotate the lifter.

Normal wear patterns are
slightly off center on the lobe. Reprinted with the
permission of Ford Motor Company.
- If the wear pattern extends
to the edges of the lobe, the lifter will not
rotate.
- If there is any scoring or
galling, the camshaft will have to be replaced
or reconditioned.
Premature lobe and lifter wear
is generally caused by metal-to-metal contact
between the cam lobe and lifter bottom due to
inadequate lubrication. The nose will be worn from
the cam lobes, and the lifter bottoms will be worn
to a concave shape or may be worn completely away.
This type of failure usually
begins within the first few minutes of operation. It
is the result of insufficient lubrication.
