hi people.
i would ask you something.Who can explain me how does work diesel
engine.?and what kind of system it need to work normally.
..thx for your ansver...


They use diesel fuel which has a very low auto ignition temp (about
200-210C) so if a "vapour" of diesel sees 200C it auto ignites without a
spark.

Petrol gasolene has a higher auto ignition temp (250-280C) so it needs
an electric spark to ignite it.

The "system" needed is a very high pressure pump to inject the diesel
into the cyl at the right time, & create a very fine atomisation so it
may auto ignite becasue the air inside the cyl is above 200C.

Unlike a petrol gasolene engine a diesel increases power by increasing
the effect time the diesl is being injected & auto ignited, so usually
diesels can generate more torque per unit of fuel burnt becasue the burn
can continue even after the piston commences to retreat down the cyl.

Of course if you're wondering where your union retirement money went,
have a look at what the union the liar Krause works for pays it's own!!!
I also suspect the phantom boat ownership is hiding the fact that the
union thinks it's just PR buying toys with other peoples' money, after
all they have a corp jet


We have first-class benefits, including a top-of-the-line health
insurance plan, a non-contributory defined-benefit pension plan, a
401k,
and a life insurance policy equal to annual salary. We contribute a
share of profits to the 401k on behalf of the employee. Our
employees
pay $4.50 for generic prescriptions and $8.00 for non-generics, but
that's going up next year to $10 and $15. New employees get two
weeks
vacation the first year, and that goes to three weeks the third
year. In
addition, we have 12 paid holidays and we shut down from noon on
Christmas eve to the day after New Year's Day. We also provide 20
days
of paid sick leave a year. And we have an outside company
administering
pre-tax flexible bennies for our employees.
Our fringe benefit package follows the trade union model,
except, of
course, for the profit contributions to 401k's. Trade unions are
not-for-profit enterprises.
How do these compare to the bennies at your shop?

Paid? Every year? I call "bull****". With 3 weeks vacation, 12
paid
holidays, and 20 paid sick days that's 47 *paid* days off every
year. Are
they hourly employees? For a "small business", that's the road to
bankruptcy.

Boy...and you had me going there for a minute.

Not quite so simple, though you are trying hard to make it so. Our
business is up because we're on the cusp of an election year. Our
business always goes up in a major election year.
You could say we're going to be doing very well in 2004 because
Bush is
such a total failure.


The 20 paid sick days aren't part of the "paid" days off unless
those
days are used. None of our people abuses sick leave. In fact, no
one as
yet has even come close to using 20 sick days in one year. They're
there
in case they're needed.


Oh, I forgot. We also provide everyone with LTD.

The company provides an insurance plan that pays 50% of an
employe's
salary for Long Term Disability. Employes have the option of
purchasing
an additional 16.66%, bringing their total to 66.66%. The basic
benefit
maximum is $4,000 per month. With the buy up, the limit is
increased to
$10,000 per month.
