A diesel engine doesn't...

[Riaanv1]

Hi all

After reading a line here by someone earlier today it reminded me of what my old man always used to tell me : " A diesel doesn't like short trips, it likes to keep running. "

But he never technically explained it, really. We all know it's better for an engine to keep at operating temperature and keep oil pressure up.

But how does a diesel engine, more so than a petrol, not like short trips?

Who is a diesel engine expert here, that can shed some decent light on the statement above?

It is said that you should never start an engine and have to switch it off again before it reaches optimal operating temperature, yes?

Well, a diesel takes a hell of a lot longer than a petrol to warm up to operating temp. So it can still be pretty cold when switching off after a short trip compared to a petrol engine.

As far as I know it's to do with the particulate filter that becomes clogged up when only driving for short distance too often. It's not that big a deal with modern cats though as they will go into a filter cleaning mode after a while so the engine will keep on running after its been switched off to generate enough heat to clean the filter. I may have bodged the technical aspects of it though but something like that

The first thing I do when I start my diesel is deactivate that accursed Auto Stop/Start garbage.

Maybe in the older days, but not today, else there wouldnt be start/stop technology fitted to the diesels.

As for the start/stop function, it never bothers me as I always stick my car into manual mode which disables the start/stop feature.

I disagree with this. Todays engines are what I like to call "throw-away" engines. I don't see modern engines out-living the engines built and designed 10 to 20 years ago.

I bet, if you were to detune a modern engine to produce the equivalent power of its counter part of 20 years ago, the modern day engine will outlast it by a country mile.
