The 2286 petrol engine appeared in 1958, but the diesel in 2.0 litre form
over a year earlier, to be replaced by the 2286 diesel in 1961. The two
diesel engines are essentially identical except that the 2.0 has wet
sleeves with an increased bore for the 2286. Both the diesel and petrol
engines were probably running in prototypes as early as 1955, and the basic
design work presumably dates from the very early fifties.

Perhaps not brilliant, but there were practically no other comparable
diesels from the fifties at all. The Mercedes is the only one that comes to
mind. Other similar capacity engines were much heavier and lower power.

Refs. For example: The Landrover Story, James Taylor 1996 ISBN 1 85520 3391
p.69 describes how the Landrover wheelbase was increased by two inches in
early 1956 to accommodate the new engine, which was introduced fairly late
in 1957 in the 2 litre wet sleeve diesel version. The petrol version did
not appear until 1958 and the 2.25 diesel until 1961.
Another reference is: The Landrover, Graham Robson 1976, ISBN 0 7153 7203 3
p.38 describes the introduction of the 2 litre diesel in June 1957 and the
introduction of the 2.25 petrol engine in 1958 is described on the
following page.

I don't think so! The early 2286 petrol engines had much smaller crank
journals and had the same short (top to bottom ) timing case as the 2 litre
diesel. On the later 2286 engines from about '65 with the bigger bearings
the crankshaft was cast iron on the petrol and forged steel on the diesel
with the same size bearings for both. Also the water pumps were different
along with the timing case and head castings. You can tell the early blocks
by the size of the side core plugs as well

I'm sure you mean '59 not '69, that would be the small crank version which
didn't last long.

Now thats a new one on me, a diesel Rolls B40.

And crankshaft. And flywheel.
> Yes but it was still an awful diesel.
No it wasn't, it was absolutely reliable and if you ground the camshaft,
lightened the valve gear and cam rollers, polished the con-rods, balanced
the crank, upped the injector pressures and played with the timing it would
equal if not outperform the petrol version and still return 25 m.p.g.
Marvellous in those days. What nostalgia!

No I meant I had it first in 69 by which time it was 11 years old.

No the B40 shared lots of bits with the B80 which was in army service,
I think the ferret had common parts too. So the champ was designed
with it to appeal to the army, made it expensive.

Sorry, I misunderstood, must learn to read properly!

And the Humber Pig, with a B60 version I think, correct me if I'm wrong,
and yes I see what you meant.
