The purpose of the valve train components are to open and close the valves. The valves need to open and close in order to intake fuel through the intake valve and release exhaust through the exhaust valve.

The valvetrain consists of all the components responsible for transferring the rotational movement of the camshaft into the opening and closing of the intake and exhaust valves. Typical components are listed below in order from the crankshaft to the valves.

A valve train is a component that is designed to open and close the intake and exhaust valves so that air and fuel mixtures can enter and leave the combustion chamber as gases. Nowadays, engines are designed with overhead cam assemblies, which are known as overhead camshafts.

The valve train refers to the assembly of components designed to open and close the intake and exhaust valves. Most new engines have overhead cam assemblies like the one shown. Other designs locate the camshaft lower in the engine and use push rods to move valve assemblies.

2024年1月13日 · Valve train components include camshafts, pushrods, rocker arms, and valves, crucial for valve train performance. Quality valve train materials and proper maintenance are essential for optimal operation.

2018年1月31日 · Lifters, rockers and push rods are important parts to keeping valvetrain operation consistent. Even in milder performance builds it is good insurance to invest in a set of higher-strength push rods. The engine itself plays a big …

The main components of a valvetrain include the camshaft, a long metal rod used in overhead valve engines, and the rocker arm/bucket tappet, which is used in overhead camshaft engines. The camshaft lobe or rocker arm controls the timing and lifts the profile of the valve opening.

In this article, we’ll explore the various parts that make up the valve train and their roles in the engine’s operation. Camshaft: At the heart of the valve train lies the camshaft, a rotating shaft with eccentric lobes or cams that actuate the valves.
