An engine’s efficiency depends on various factors; among which, its capacity of air processing plays an important role in the production of power. An internal combustion engine uses an air-fuel mixture to produce power, but air is relatively difficult to consume as compared to fuel. The automotive rocker arm is an important part of the internal combustion engine. An automotive rocker arm is an oscillating lever that converts the radial movement of cam lobe into a linear movement at the poppet valve, so as to open it. When the camshaft lobe lifts the outer side of the automotive rocker arm, the inside presses the valve stem down so as to open the valve and air is sucked into the cylinder. Hence, the automotive rocker arm
plays an important role in providing a means of multiplying the lift ratio, which is crucial in the working of an engine.
Automotive Rocker Arm Market: Trends, Drivers, Restraints
Nowadays, due to various technologies and inventions, many automobile manufacturers focus on producing light weight engine. Attributing to this, designers attempt to reduce the weight of an engine by reducing the weight of various parts used in it. Lightweight automotive rocker arms are commonly used in high rpm applications. As steel has more fatigue strength and stiffness, many manufacturers are using steel automotive rocker arms, which are as light as aluminum ones. Further to this, reduced weight of the automotive rocker arm equates to less load on valve springs, which produce more rpm.

Aftermarket automotive rocker arm manufacturers are coming up with new technologies and inventions that are helping the automotive rocker arm industry grow. Also, increasing demand for automobiles globally is fueling growth of the global automotive rocker arm market. Many companies are using various lightweight materials, such as aluminum, and steel, among others in the manufacturing of automotive rocker arms – so as to reduce the overall weight of an engine. Lightweight automotive rocker arms are essential for efficient operation, but strength also plays an important role in the life of an automotive rocker arm.
An automotive rocker arm is a crucial part of an engine, as its failure makes the engine useless. Moreover, it is expensive to replace and procure automotive rocker arms. Automotive rocker arms fail mainly due to stress concentration and as an effect of loading. This problem of failure has not been completely overcome and designers are trying to explore new technologies and methods to prevent it. Attributing to this reason, various companies are investing heavily in research and development.
