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.
For twin-cam or DOHC engines, VCT was used on either the intake or exhaust camshaft. (Engines that have VCT on both camshafts are now designated as Ti-VCT.↓) The use of variable camshaft timing on the exhaust camshaft is for improved emissions, and vehicles with VCT on the exhaust camshaft do not require exhaust gas recirculation (EGR) as retarding the exhaust cam timing achieves the same ...
In a piston engine, either a timing belt (also called a cambelt) or timing chain or set of timing gears is a perishable component used to synchronize the rotation of the crankshaft and the camshaft. This synchronisation ensures that the engine's valves open and close at the correct times in relation to the position of the pistons.
Hydrosteer was the name given by George Kent Ltd and Cam Gears Limited through Hydrosteer Limited [1] of Luton, England, to its automotive power steering system. Initially Hydrosteer manufactured the Ross-Link system for commercial vehicles from 1953 under licence from Ross Gear and Tool of U.S.A. [2] Their own product available from 1961 was based on a cam and peg system and was characterised ...
As the camshaft lobe travels through its apex, the load is reduced on the lifter piston, and the internal spring returns the piston to its neutral state so the lifter can refill with oil. This small range of travel in the lifter's piston is enough to eliminate the need for frequent lash adjustment. Hydraulic Tappet Parts Hydraulic Tappet Cross ...
Valve timing gears on a Ford Taunus V4 engine. The balance shaft runs off the small gear on the left (the large gear is for the camshaft , causing it to rotate at half the speed of the crankshaft). Balance shafts are often used in inline-four engines , to reduce the second-order vibration (a vertical force oscillating at twice the engine RPM ...
A double dwell cam mechanism has a motion function which follows a rise-dwell-fall-dwell motion function sequence that repeats. Unlike the single dwell, the rise function position ends with the follower's acceleration becoming zero, as it is stationary in the first dwell.
A Bishop Cam steering box was a simple but adequate screw and follower design of steering box for vehicles. It took its name from being manufactured by a special method of cutting steering gears which had been patented by Reginald Bishop of London in the early 1920s.
