通用汽车首席执行官瓦格纳先生的梦想
通用汽车首席执行官瓦格纳先生的梦想是用其同盟者的力量获得海外市场的份额。但是看来这个梦想并不是马上能实现的。 上周，这个世界第一的汽车制造商决定，它别无选择花费五亿一千二百万美元担保日本五十铃公司，以获取其非常需要的柴油机技术。 这笔钱，加上通用在富士重工，铃木汽车，五十铃汽车以及其中国合资企业的投资，希望能确保能大幅增加通用在亚洲市场的份额。而此时，日本厂家正在大举进入美国市场。 通用正在克服困难将其同盟者战略变为现实： 在日本，南朝鲜和中国销售汽车并赚到钱。看来，这个战略是昂贵的，充满艰辛的。 上周，通用遇到了新的挫折，据透露，通用接管南朝鲜大宇汽车公司财产的计划又被推迟。经历了两年艰苦谈判和罢工，拯救破产的大宇汽车仍然是艰苦的历程。 通用支付了两亿五千一百万美金获取大宇在南朝鲜及越南的工厂，而债权人之间的争吵不断导致计划延期。通用亚太总裁傅雷得里克说：“我们很失望，但是那是一个很大的破产案”。 去年，通用在五十铃亏损严重，通用的老板们说他们不会在该公司投入更多的钱。 瓦格纳先生不想在亚洲建设新工厂，而是希望网罗那些小型分散的汽车厂商作为跳入亚洲市场的跳板。亚洲市场正处在其婴儿期并且增长迅速。 通用在亚太地区（包括澳大利亚）的市场占有率仅为4％，通用希望将来能达到10％。这个市场年销售量目前是一千二百万量，十年内或许会达到两千万辆。

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