One of the most reliable internal combustion engines around is the
diesel engine. In many industrial installations, diesel engines are
used as prime movers for the generation of electricity and for
emergency air compressors.
It's true that they are rugged, but one of the most important
advantages of these engines is the fact that they can be started by
manual cranking. In remote areas, diesel engines can be counted upon
for starting up from scratch.
Once a small diesel engine is started, it can be used to drive a small
electrical generator that can then be used to produce electrical
supply for driving other machines like pumps, compressors, and for
lighting.
How does a diesel engine work?
First there must be combustion of fuel. As we have discussed in our
previous articles, combustion or burning of fuel occurs whenever there
is sufficient heat, fuel and oxygen. When conditions are just right,
combustion can be very rapid. Rapid combustion causes an explosion in
an enclosed area. This is because of the rapid built-up of hot gases
during the process....

   He (it) is just a fairly new breed of spammer that has popped up in the last
year or so.  I call them "click miners".  Their objective is to lure you to
their site, where you will hopefully click on some of the ads posted there,
which will earn them a few pennies.  Multiply by thousands of clicks and the
spammer eventually gets a miserable little check in the mail from somewhere.

   Spammers are the scum of the earth.

I have no connection to the original poster and am most certainly NOT
a spammer, however I do have an interesting anecdote regarding diesel
engines.

I was in Nigeria waiting at a river crossing in a Land Rover for the
daily ferry boat. Also waiting were about a dozen or so diesel freight
trucks, with the drivers dozing in the shade. The trucks were all
parked on a slight incline leading down to the ferry landing.

When the ferry arrived, all the drivers went to the first truck in
line. They joined together and pushed to get it rolling just a few
feet. The man at the wheel popped the clutch and the diesel cranked up
instantly. The drivers then back up the line, repeating this process
for each truck until they were all running. It was obvious that this
was their standard procedure for starting up their diesel engines when
the ferry arrived.

I was impressed both by the well-organized teamwork and by the fact
that every one of those diesels started immediately after only about
one or two revolutions of the crankshaft. Of course the ambient
temperature was ~ 80F, which certainly helped.

Common practice at rural funerals during the '50's.

Had a class mate with a used '53 VW that would only park (facing out) on the
top of an incline as his electric starter was a bit intermittent. (guy was
snake bit, neither his battery nor his girl friends would put out)
