Aluminum offers lighter weight at the expense of strength, hardness and often cost. However, with care it can be substituted for many of the components and is widely used. Aluminum crank cases, cylinder blocks, heads and pistons are commonplace. The first airplane engine to fly, in the Wright Flyer of 1903, had an aluminum cylinder block. [1]
Most engines have at least two main bearings— one at each end of the crankshaft. Additional bearings may be located along the crankshaft, sometimes as many as one bearing per crank pin, as used on many modern diesel engines and petrol engines designed for high RPM. [1] Some small single-cylinder engines have only one main bearing, [citation ...
Alusil as a hypereutectic aluminium-silicon alloy (EN AC-AlSi17Cu4Mg / EN AC-48100 or A390) contains approximately 78% aluminium and 17% silicon. [1] [2] This alloy was theoretically conceived in 1927 by Schweizer & Fehrenbach, [3] of Badener Metall-Waren-Fabrik, [4] but practically created only by Lancia [5] in the same year, for its car engines.
Rheinmetall Automotive ranks among the 100 biggest auto industry suppliers worldwide and is an important partner to the industry for such products as exhaust gas recirculation systems, secondary-air systems, coolant pumps, and pistons for car gasoline engines and as well as for the commercial vehicle sector.
The crankshaft and connecting-rod big-end bearings in current automobile engines are made of a replaceable steel shell, keyed to the bearing caps. The inner surface of the steel shell is plated with a coating of bronze , which is in turn coated with a thin layer of Babbitt metal as the bearing surface.
Most automotive engines use aluminum pistons that move in an iron cylinder. The average temperature of a piston crown in a gasoline engine during normal operation is typically about 300 °C (570 °F), and the coolant that runs through the engine block is usually regulated at approximately 90 °C (190 °F).
The Chevrolet Stovebolt engine is a straight-six engine made in two versions between 1929 and 1962 by the Chevrolet Division of General Motors.It replaced the company's 171-cubic-inch (2.8 L) inline-four as their sole engine offering from 1929 through 1954, and was the company's base engine starting in 1955 when it added the small block V8 to the lineup.
It was unveiled at the Melbourne International Motor Show on February 29, 2008, [68] and went on sale in August 2008. The first Australian car to be fitted with this engine, however, was the CSV GTS of 2007, which was claimed to have a power output of 400 kW (536 hp) and 600 N⋅m (443 lb⋅ft).
