But it was the Cleveland of 1909 which gave a refinement of the type so to speak, the Cleveland had an overhead valve with a rocker arm. But the Cleveland was a direct descendent of the two-stroke engine, with its high compression ratio, low maximum pressure, and Figure 4) wide-bore cylinder, the rest of the Cleveland was a compilation of steam engine features, a simple water-cooled overhead valve camshaft, two-speed direct drive with a bevel gear to a camshaft driven by a worm and spur gear, two-speed clutch drive for the flywheel and high-pressure lubrication. The later Wilbur engines began the supercharger with reduced-imulsion air supply through two pipes which were a short distance from the exhaust valve. This raised the speed of the engine and produced a powerful explosion.
In 1903 the A S Brown company first exhibited a motor car based on the complete engine and this quickly became known as the Brown, and was an immediate success. in 1929 the Ford company bought them all up. The Ford Brown was not immediately a success and a series of improvements were made to the engine in order to increase the power output, these were relatively simple modifications to the basic engine but the flywheel was redesigned, the oil pump was relocated, a fuel pump mounted on the camshaft and a dry sump lubrication system was adopted. In order to get the maximum power output it was necessary to overcome the inherent vibration of the engine caused by the single flywheel and an overdrive transmission driven by the crankshaft was installed. A further alteration was the adoption of a four-valve cylinder head and carburettor instead of the two-valve carburettor. The engine became known as the Rolls Royce engine after Rolls Royce who bought an exclusive licence to manufacture them. Rolls Royce later produced a further refinement of the design and put in a supercharger to increase the power. The Rolls Royce engine won the Le Mans race, the Figures 5 to 7. in the 1919 Le Mans race seven of the 10 cars used Figure 8 this engine. Rolls Royce went on to develop an extensive range of motor car engines, until the acquisition of a small amount of the firm by American Vickers in 1920 at which time they began to develop a completely new engine, the Maybach engine, for a new product, the Salmson.
