Figure 85.—The famous Rolls-Royce "Silver Ghost" series started with the 1 907 version, of which this is a model, and was continued for almost 20 years with only minor mechanical changes. The full-sized car has a 6-cylinder engine of 41//2-inch bore and 41//2-inch stroke, developing about 48 horsepower. The cylinders are cast in two groups of three, with the valves all on one side and operated from a single camshaft located in the crankcase. The crankshaft is hollow and has a main bearing between each two adjacent cranks. Forced lubrication was provided. The crankcase is of aluminum, and the oil pan can be easily removed for in- spection. The fuel mixture was supplied by an automatic carburetor, which could be adjusted for richness from the dashboard, and the speed was controlled by a centrifugal governor acting on a throttle valve. Both battery and magneto ignition are fitted to the engine, each system using a separate set of spark plugs. The cylinders were cooled by water jackets into which the water was forced by a rotary pump from the radiator, in front of the engine. A belt-driven fan is mounted behind the radiator. 118.
