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.

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
