Cummins L10

The horizontal LT10 engine is to be available in the same three ratings as the vertical L10 models — 180, 250, and 290bhp (134, 186 and 216kW). The most powerful 290bhp engine is aftercooled in addition to being turbocharged.
Engineering changes made to produce the new version are based on a cylinder block laid over 86 degrees from vertical. The fuel pump is positioned on the engine's top surface.
The major parts difference from the vertical engine includes a new split cast iron gear cover. This incorporates drives for the camshaft, fuel system, air compressor, lubrication, water and hydraulic pumps, A scavenger type oil pump is fitted to suit the unit's dry sump configuration.
