Diesel engine wearing during the start up

[21121956]

Hello everybody:

For a medium speed Diesel engine, I would like to know if an equivalent exists between the wearing down that suffer at the time of the starting up and the wearing down that suffers in normal operation; i.e. one start up equals, let us say, 20 or 50 hours of operation.

Thanks in advance

I dont think that its more dusty and nasty than downtown Detroit in most of the rural areas I've seen.

then again this question is going the way of the "combustion chamber pressures" thread.

We need to differentiate between the different types of diesel I think.

That said I'd bet that the "myth" of cold starts killing motors is more "fact" than myth.
