Valve helical spring is a critical part in valve train of the IC engine. It absorbs energy while opening of the valves and release energy during closing of the valves. It is basically a compression types of helical spring used in commercial vehicles. Spring stiffness plays a vital role in design of helical valve spring. The primary part of designing of valve helical spring is to define the stiffness of spring as per requirement of engine design. Then to design for space constraints, to design for high fatigue strength, and to design for reliability.
