Rocker arms contain the cams to give motion to the values timing.

But in some engine the cam is directly operate the valve. There is no rocker arm. A seem is placed between valve stem and cam.

This seem is calibrated.

But most of the engine the power from camshaft is transmitted through camshaft pulley belt drives to valves.

Leelakrishna said: (Feb 4, 2014)  
Power from main engine shaft is taken by the cam during running conditions. And the cam will transfer this power to the rocker arm because of its point contact. And finally this power will transfer to valve through its stem.

Camshaft helps the the valves to inlet and outlet of combusted air, some may possess pulleys drives and some may possess directly through chain.

In pushrod engine, rocker arm transmits power to the valve. But in some of the engines (OHC, DOHC) camshaft directly transmits power to the valves.

What is calibrated which engine use in calibrated?

What is the revolution of camshaft while crankshaft revolve on time?

C.V.Rajesh said: (Nov 3, 2015)  
The main role of cam shaft is to transmit the power push rods-rocker arm-engine valves. The cam shaft powered by crankshaft by means of gears.

Now a day all engines valves are operated by cam shaft directly with out any push rods and rocker arms.

Selvam Cr said: (Feb 19, 2016)  
Nowadays, valves are directly controlled by cam shaft. Rocker arm also needs a push rod to control the valves. That why we don't go for the rocker arm.

Kolli Kishore said: (Jan 3, 2017)  
Rocker is the link which is placed between cams and the valves. Due to the motion of cams the rocker arm moves then the value gets motion.

Vishnu said: (Jan 18, 2017)  
This is happening only the engine having overhead valve mechanism, and now most of the modern vehicle having overhead valve mechanism.

Karthik said: (Apr 23, 2017)  
Rocker arms contain the cams.

Neelesh said: (Jun 28, 2018)  
Rocker arms means?

Gokul said: (Sep 16, 2018)  
Rocker is the one of the main parts of engine neelesh what you know about automobile you are very weak in this section.

Anish Yadav said: (Dec 2, 2018)  
Rocker arm is the correct answer.

Anomie said: (Feb 9, 2019)  
Push tube is the correct answer.

Williams Innocent said: (Mar 2, 2019)  
Most engines valve are been controlled by the cam shaft through the help of crack shaft belt or chain.

David said: (Sep 8, 2019)  
The rocker arm transfers motion from the camshaft to the valves.
