The cam can be seen as a device that converts rotational motion to reciprocating (or sometimes oscillating) motion. [clarification needed] [3] A common example is the camshaft of an automobile, which takes the rotary motion of the engine and converts it into the reciprocating motion necessary to operate the intake and exhaust valves of the cylinders.
A camshaft operating two valves. A camshaft is a shaft that contains a row of pointed cams in order to convert rotational motion to reciprocating motion.Camshafts are used in piston engines (to operate the intake and exhaust valves), [1] [2] mechanically controlled ignition systems and early electric motor speed controllers.
The first known automobile engine to use a timing belt was the American 1954 Devin-Panhard racing car, used an engine converted from pushrods to overhead camshafts through the use of a toothed belt made by the Gilmer Company. [18] [19] This car won the Sports Car Club of America (SCCA) National Championship in 1956. [20]
SOHC design (for a 1973 Triumph Dolomite Sprint) . The oldest configuration of overhead camshaft engine is the single overhead camshaft (SOHC) design. [1] A SOHC engine has one camshaft per bank of cylinders, therefore a straight engine has a total of one camshaft and a V engine or flat engine has a total of two camshafts (one for each cylinder bank).
These engines differed only in that the L78 had a solid-lifter camshaft, while the L37 had a hydraulic lifter cam shaft. In 1966 the L78 was available exclusively in the intermediate line. For 1967 the engine was additionally available in Chevrolet's new pony car, the Camaro. The following year the motor became available in the compact Chevy II ...
A cam engine is a reciprocating engine where instead of the conventional crankshaft, the pistons deliver their force to a cam that is then caused to rotate. The output work of the engine is driven by this cam. [1] A variation of the cam engine, the swashplate engine (also the closely related wobble-plate engine), was briefly popular. [2]
The helical camshaft prototypes typically cost about $1500 in machining and materials. [citation needed] This figure would reduce greatly in production. The cost of the helical camshaft is really only high when considered in comparison to a conventional camshaft which reportedly cost the manufacturers only a few dollars per unit to make.
New options were introduced for the Barracuda as the competition among pony cars intensified. The 273 engine was made available as an upgraded Commando version with a four-barrel carburetor, 10.5:1 compression, and a more aggressive camshaft, still with solid tappets. These and other upgrades increased the engine's output to 235 bhp (175 kW).
