What's the Rocker arms & How Does It Work?

Rocker arms are reciprocating lever used in an internal combustion engine. They are typically located between the intake and exhaust valves and pushrods which are connected with crankshaft below the engine.

When the crankshaft rotates it cause up and down movement of the pushrods, then the pushrods pushed and pulled the rocker arm to rock up and down which cause opening and closing of the intake and exhaust valves. Then power can flow from the combustion chamber of engine through various parts to the wheels to put the vehicle in motion.

The broken and loose rocker arm cause poor performance of the engine, the engine will be enable to take the full load of the vehicle and in severe cases engine failed to start.

The HEMIV-8 engine can achieve automatic smooth switch between 4-cylinder mode and 8-cylinder mode in 40 milliseconds. When the engine does not need the full power operation, it can instantly shut down four cylinders. When needed, the MDS can quickly restore cylinder operation to release all engine power, greatly improving fuel economy. The fuel compression ratio is 7.5:1, and this technology ensures that the vehicle's overall fuel consumption is reduced by 20%.
