I've never heard the term 'caustic' used in relation to organic
solvents before - what exactly do you mean?


The reason for
pollution from a diesel is lack of maintenance not poor design. If you
see a diesel belching smoke, inform the driver and if you see it doing
so again, inform the police, there is a phone number for such reports;
I believe it goes to your local council.

That would involve stopping just about every diesel driver on
the road, including those in brand new diesel BMWs (supposedly
one of the most refined diesel engines around).


It is an offence under the clean air act to pollute the atmosphere
with a badly maintained engine of any sort. That's what the MoT
emissions test is set up for.

It isn't about them being badly maintained - diesel engines will
all (ok I haven't tested them all, but the vast majority at any
rate) beltch out black smoke *under high load*.

Do you actually have any real life experience of diesel engines??
