Throughout the 1950s there was an increasing demand for a diesel-engined Land Rover. Diesel technology had improved enough to make small-capacity high-speed engines practical. Diesel power had also become prominent in industrial and agricultural uses throughout the world, and fleet users of Land Rovers were often in the situation where their Land Rovers were the only petrol-engined vehicles in their fleet, making servicing and fuel supply issues more complex.
In 1954 the Rover Motor Company was in talks with Standard-Triumph about the possibility of a merger. Standard were Britain’s pioneers of road-going small diesel engines with the 20C engine fitted to Ferguson tractors and the Standard Vanguard car (Britain’s first diesel car). Rover engineers were able to study Standard’s diesel designs as part of the negotiations. The merger was called off, but Rover had gained vital experience and knowledge in developing small diesel engines.
The result was a wet-liner 4-cylinder engine. Fuel injection equipment was from CAV, and the engine used Ricardo’s "Comet" swirl chambers, but with Rover-developed 'dimples' to produce quieter and smoother running. Heater plugs were fitted to each combustion chamber to improve starting. The engine was launched in the Land Rover in 1957, with the vehicle requiring an extra 2 inches of length added to the chassis in the engine bay to enable the new engine to fit. The engine’s power output and speed range was close enough to the existing petrol engine to allow the same transmission unit to be used on all vehicles.
