Rocker arm

Index Rocker arm

A rocker arm (in the context of an internal combustion engine of automotive, marine, motorcycle and reciprocating aviation types) is an oscillating lever that conveys radial movement from the cam lobe into linear movement at the poppet valve to open it. [1]

Cam

A cam is a rotating or sliding piece in a mechanical linkage used especially in transforming rotary motion into linear motion.

Cylinder head

In an internal combustion engine, the cylinder head (often informally abbreviated to just head) sits above the cylinders on top of the cylinder block.

Geometry

Geometry (from the γεωμετρία; geo- "earth", -metron "measurement") is a branch of mathematics concerned with questions of shape, size, relative position of figures, and the properties of space.

Internal combustion engine

An internal combustion engine (ICE) is a heat engine where the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit.

Lever

A lever is a simple machine consisting of a beam or rigid rod pivoted at a fixed hinge, or fulcrum.

Mechanical advantage

Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system.

Moment of inertia

The moment of inertia, otherwise known as the angular mass or rotational inertia, of a rigid body is a tensor that determines the torque needed for a desired angular acceleration about a rotational axis; similar to how mass determines the force needed for a desired acceleration.

Over-arcing

Over-arcing denotes a radial or parabolic-like "arc" that is extended beyond the path of which it was either intended to follow, or could have followed, given that a more "efficient" means had been used to instigate it.

Overhead valve engine

An overhead valve engine (OHV engine), or "pushrod engine", is a reciprocating piston engine whose poppet valves are sited in the cylinder head.

Poppet valve

A poppet valve (also called mushroom valve) is a valve typically used to control the timing and quantity of gas or vapour flow into an engine.

Rocker arm

A rocker arm (in the context of an internal combustion engine of automotive, marine, motorcycle and reciprocating aviation types) is an oscillating lever that conveys radial movement from the cam lobe into linear movement at the poppet valve to open it.

Roller rocker

A roller rocker is a rocker arm that uses bearings instead of metal sliding on metal.

Stamping (metalworking)

Stamping (also known as pressing) is the process of placing flat sheet metal in either blank or coil form into a stamping press where a tool and die surface forms the metal into a net shape.

Steel

Steel is an alloy of iron and carbon and other elements.

Tappet

A tappet is a projection that imparts a linear motion to some other component within a mechanism.

New!!: Rocker arm and Tappet · See more »

Trunnion

A trunnion (from Old French "trognon", trunk) is a cylindrical protrusion used as a mounting or pivoting point.

New!!: Rocker arm and Trunnion · See more »

Valve stem

A valve stem is a self-contained valve which opens to admit gas to a chamber (such as air to inflate a tire), and is then automatically closed and kept sealed by the pressure in the chamber, or a spring, or both, to prevent the gas from escaping.

New!!: Rocker arm and Valve stem · See more »

Valvetrain

A valvetrain or valvetrain is a mechanical system that controls operation of the valves in an internal combustion engine, whereby a sequence of components transmits motion throughout the assembly.

World War II

World War II (often abbreviated to WWII or WW2), also known as the Second World War, was a global war that lasted from 1939 to 1945, although conflicts reflecting the ideological clash between what would become the Allied and Axis blocs began earlier.
