2. 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.

3. Timing belt (camshaft) - Wikipedia

   en.wikipedia.org/wiki/Timing_belt_(camshaft)

   However a few engines since 2008 have used "wet timing belts", whereby the belt is lubricated by engine oil to reduce friction losses by 30% and thus reduce fuel consumption by 1%. [7] In some engine designs the timing belt may also be used to drive other components, such as the water pump and oil pump .

4. Nissan CA engine - Wikipedia

   en.wikipedia.org/wiki/Nissan_CA_engine

   The CA engine is a series of 1.6 to 2.0 L (1,598 to 1,974 cc) Inline-4 piston engines from Nissan.It is designed for a wide variety of smaller Nissan vehicles to replace the Z engine and some smaller, four-cylinder L series engines.

5. 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 ...

7. N-VCT - Wikipedia

   en.wikipedia.org/wiki/N-VCT

   [2] [3] NVTCS equipped Nissan engines do not have as high of engine speeds as VTEC equipped engines so NVTCS is simpler, quieter, and requires no special maintenance. [ citation needed ] Some Nissan engines only have N-VTC on the intake cam such as the GA16DE, QG16/18, SR20DE/DET (S14-15) or RB25DE/DET (R33-R34 GTS/GTS-T, GT/GTT) while others ...

9. 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.
