2. Variable camshaft timing - Wikipedia

   en.wikipedia.org/wiki/Variable_camshaft_timing

   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 ...

3. Cam (mechanism) - Wikipedia

   en.wikipedia.org/wiki/Cam_(mechanism)

   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.

   Camshaft specs: 224°/230° duration, .581" intake lift, .588" exhaust lift, 114 degrees overlap (red line at 6700 rpm) and using Shell 98/100 octane V-power gasoline, realized an increase in power to 375 kW (510 PS; 503 hp) or (503 bhp) at the flywheel and around 440 ft⋅lbf (600 N⋅m) to 460 ft⋅lbf (620 N⋅m) of torque) – approximately ...

5. Camshaft - Wikipedia

   en.wikipedia.org/wiki/Camshaft

   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.

6. VANOS - Wikipedia

   en.wikipedia.org/wiki/VANOS

   The first-generation single VANOS system adjusts the timing of the intake camshaft to one of two positions — e.g. the camshaft is advanced at certain engine speeds. [2] [3] VANOS was first introduced in 1992 on the BMW M50 engine used in 3 and 5 Series. In 1998 single infinitely variable VANOS was introduced on the BMW M62 V8 engine. [2]

7. Variator (variable valve timing) - Wikipedia

   en.wikipedia.org/wiki/Variator_(variable_valve...

   The Alfa Romeo Twin Spark engine, introduced in the 1987 Alfa Romeo 75, also uses variable valve timing. [3] [4] The Alfa system varies the phase (not the duration) of the cam timing and operates on the inlet camshaft. [5] Alfa Romeo's variator is a cylindrical chamber that contains a pressure chamber and piston along with helical splines.
