Wasn’t it the combustion chamber design and fuel injection system that was the Saurer licence? Dating back to the early 1930s and the first reliable small high speed Diesel engine. The competing system was the British designed Ricardo Comet, used by AEC with its early Diesel engines. Gardner of course beat both of them with its direct fuel injection L2 design in 1929.
It could have been Graham? The Saurer in the Morris was direct injection with the combustion chamber in the piston bowl, as was the BMC diesel. It had ‘Saurer patent’ injectors which were very slim, and a standard CAV pneumatically governed pump according to the manual.
