INTRODUCTION

Valves in internal combustion engines are like gates inside cars and machines that work using internal combustion. They control the air and fuel that go into the engine and let out the exhaust gases. These valves are really important because they make sure everything happens at the right time, helping the engine work well and efficiently.

To ensure the product quality of steel for internal combustion engines valves, the Bureau of Indian Standards (BIS) has made it mandatory for manufacturers to undergo BIS registration and obtain the BIS ISI mark before selling it in the market. Manufacturers can use the ISI Mark on their products only after obtaining a license from BIS that is granted after BIS registration. The presence of the ISI mark on a product indicates that it complies with BIS's stringent quality standards.

IS 7494:1981 covers steel for internal combustion engines valves. This standard specifies the requirements for wrought alloy and unalloyed steel bars up to and including 40 mm in diameter intended for the manufacture of internal combustion engine valves.

REQUIREMENTS FOR IS 7494:1981

1.     General requirements for material supply must be in accordance with the specified standard.

2.     Unless otherwise specified in the order, the processes used to manufacture the steel are at the discretion of the manufacturer.

3.     The material must be free of potentially harmful internal and surface flaws.
