We were somewhere around Barstow, on the edge of the desert, when
the
drugs began to take hold. I remember "Doctor Drivel"

saying something like:

Don't forget to consider the fire risk of additional insulation.

Insulation doesn't easily catch fire.

You have to balance the needs of the airflow for cooling and
combustion
and the necessity of sound insulation.

Combustion air and exhaust are ducted in and out, and the radiator
can
be mounted externally.
Even so, the temperature build-up inside a closed insulated
container
with a genset in it can be dramatic. Add to that the possibility of
a
fractured fuel line spraying fuel over insulation material.
There's always a chance some of the insulation material might come
loose
and fall on a hot turbo casing, for example.

Insulation might not easily catch fire, but soak it in diesel and
apply
an ignition source.

I demand nothing of you except that you amuse me.

Dave,

For all the reasons you mention I have 'probably' settled on using bog
standard 100mm rockwool retained by a custom made cage of wire
meshing. Both the radiator outward flowing air and the combustion air
are currently ducted but the input air to the radiator is drawn from
the totally open bottom of the trailer chassis. I will probably
enclose the bottom but leaving a largish entry port at the alternator
end so that cool air is available for its cooling as well as the
radiator. Currently kicking ideas arround about what to do under the
engine sump - I'll probably enclose it in sheet steel with rockwool
above, but incorporate a drip tray with a funnel shape leading to a
drain so any oil drips and fuel leaks don't accumulate in the
enclosure.
