Ah yes you are right.
thanks for clarifying my error.

There is an interesting compression related thread on delicaclub.ru according to which the normal compression is 28 kg/cm2=398 psi and up with acceptable difference between cylinders at 3 kg/cm2=42.7 psi. This compression provides the temperature at the injection point at 750C. If the compression is lower then you will have a rough start when it is cold. Hmm... Sounds like my case. The recommended method of measuring compression is through the injectors' mounting; removing glow plugs (which is more convenient) you are adding some volume to cylinders and the compression numbers might not be accurate. Also you have to make sure that the starter is providing at least 200 rpm.

I found the compression values from the manual, and it's given them in kPa. It's always very confusing when different sources provide values in different units.

That being said, "Joe Diesel Mechanic" Green1 is getting to look at his ride is probably using a gauge which reads in psi anyway, so neither kiloPascals nor kilograms per cubic centimeter is going to mean much to him.

Right, that is why I provided the converted numbers. If you are confused use this: http://www.engineeringtoolbox.com/press ... d_569.html

Mararmeisto, I believe you meant 'square centimeters'.

Dagnabbit! I did too mean squared centimetres!

Sorry, I was studying radar theory all afternoon yesterday, refreshing some of the 'finer' points of my training, so I had a swirl of numbers and theory in my head. Coincidentally, the book I was reviewing did a similar thing as this thread: speed of light in one section of the book was listed in feet/microsecond, while later in the book it was described in terms of metres/second. Made it difficult to follow along.

Go metric all the way! It makes life easier.

Many government topo maps used to be (wouldn't surprise me if they still are) done with distances in kilometres, but hight in feet, made it rather difficult to calculate grades...

Another useful site for doing conversions is Conversions Online (http://www.onlineconversion.com).
They convert:
3040 kPa = 440.9 psi standard
2020 kPa = 293.0 psi min
0300 kPa = 043.5 psi for difference between cylinders
