In 1922, Bugatti presented a production car with an eight-cylinder engine for the first time. For this, the mechanics around Ettore Bugatti joined two four-cylinder engine blocks together. They also added a housing for the overhead camshaft and a one-piece crankcase that was firmly attached to the frame. At the front end, a vertical shaft transmitted the revolutions of the crankshaft to the camshaft. A magneto dual ignition system and later a battery ignition system provided sparks in the cylinders. Meanwhile, two Zenith carburetors provided the necessary fuel-air mixture. There were two overhead intake valves and one large exhaust valve per combustion chamber. Bugatti had already tried out this design shortly before in an aircraft engine. At that time, the two-liter displacement produced an impressive 75 to 100 hp, depending on the version. This enabled the Type 30 to reach between 75 and 90 mph.<\/p>\n\n\n\n

Actually, the engine was supposed to have a displacement of three liters. Ettore Bugatti had already had a similar engine fitted to a Type 28 prototype. However, the Grand Prix regulations changed and stipulated a maximum of two-liter power units for the subsequent period. Bugatti changed the specifications and used the inline eight-cylinder engine for the first time in the Type 29 Grand Prix racing car. But it wasn’t the engine alone that made the Type 30 so innovative. The forged front axle with hydraulic drum brakes was taken over from the Type 22. At that time, it was still common for cars to have brakes only on the rear axle. Bugatti also developed cast brake shoes with worm-shaped recesses for the rear brake drums. Starting in 1924, the company switched to a cable system on the front axle due to material problems. A new locking system was used for the bolts, for which Bugatti was granted a patent.<\/p>\n\n\n
