A crosshead as part of a reciprocating piston and slider-crank linkage mechanism. Cylindrical trunk guide Hudswell Clarke Nunlow; crosshead and two slide bars. In mechanical engineering, a crosshead [1] is a mechanical joint used as part of the slider-crank linkages of long stroke reciprocating engines (either internal combustion or steam) and reciprocating compressors [2] to eliminate ...
Draw the crank arm pivot point anywhere on this ground level. Once the pin positions are correctly placed, set a graphical compass to the given link length of the crank arm. Positioning the compass point on the pivot point of the crank arm, rotate the compass to produce a circle with radius equal to the length of the crank arm.
Variable stroke engine (Autocar Handbook, Ninth edition) A mechanical linkage is an assembly of systems connected so as to manage forces and movement.The movement of a body, or link, is studied using geometry so the link is considered to be rigid. [1]
Connecting rod and piston from a car engine. A connecting rod for an internal combustion engine consists of the 'big end', 'rod' and 'small end'. The small end attaches to the gudgeon pin (also called 'piston pin' or 'wrist pin' in the U.S.), which allows for rotation between the connecting rod and the piston.
Ray-traced image of a piston engine. There may be one or more pistons. Each piston is inside a cylinder, into which a gas is introduced, either already under pressure (e.g. steam engine), or heated inside the cylinder either by ignition of a fuel air mixture (internal combustion engine) or by contact with a hot heat exchanger in the cylinder (Stirling engine).
On an engine with a distributor, the contact breaker can be found beneath the distributor cap. The position of the contact breaker is set so that it opens (and hence generates a spark) at exactly the optimum moment to ignite the fuel/air mixture. This point is generally just before the piston reaches the top of its compression stroke.

A flexplate or flex plate is a metal disk that connects the output from an engine to the input of a torque converter in a car equipped with an automatic transmission. [1] It takes the place of the flywheel found in a conventional manual transmission setup.
