In the mid 1950's,
many existing Series 1 Land Rover owners were encouraging
Rover to produce a diesel-engined Land Rover so that they
would share a common fuel with the other farm machinery which
Rover designed a completely new diesel engine for the Series
1 Land Rover with upto 50% claimed increased fuel economy
over the alternative 2 litre petrol engine. It also had very
similar power output but reduced torque. It became available
for the Series 1 Land Rover in 1957 and continued over into
the Series 2 Land Rover until 1961.
During a 1,000mile independent road test, the engine delivered
an overall fuel consumption of 29.5mpg (4.5km/l). The engine
oil consumption for the Land Rover during the test was quoted
as 4,000mpg (1,420km/l).
The engine design was such that it would be able to form the
basis for a larger bore petrol engine which would fit the
existing transmission. It was a common theme of Rover to design
Series Land Rover components to be as compatible as possible
with existing models.
The engine has a reputation for being noisy but that is
more to do with it's environment in situ, where typically
flat body panels of a Series 1 Land Rover can vibrate and
resonate. Tyre noise also adds to exercising the ear drums.
The engine can be fitted as a direct swop for the petrol engine
in Series 1 88in and 109in Land Rovers but not for those with
the 2in shorter chassis.
