A connecting rod, also called a 'con rod', [1] [2] [3] is the part of a piston engine which connects the piston to the crankshaft. Together with the crank, the connecting rod converts the reciprocating motion of the piston into the rotation of the crankshaft. [4] The connecting rod is required to transmit the compressive and tensile forces from ...
Bent connecting rod after Hydrolock Same connecting rod, turned 90°. Hydrolock (a shorthand notation for hydrostatic lock or hydraulic lock) is an abnormal condition of any device which is designed to compress a gas by mechanically restraining it; most commonly the reciprocating internal combustion engine, the case this article refers to unless otherwise noted.
The main connecting rod is a large triangular frame, driven by both cylinders and driving the crankpin. Owing to the phase difference between the cylinders, this frame tilts back and forth as the engine rotates and so the cylinder crossheads drive it through two short connecting rods, allowing for some movement side-to-side.

A 180-degree V engine as used in the Ferrari 512BB has opposed cylinder pairs whose connecting rods use the same crank throw. Contrary to this, in a 'boxer' engine, as applied in BMW motorcycles, each connecting rod has its own crank throw which is positioned 180 degrees from the crank throw of the opposed cylinder.]
Then, using the triangle sine law, it is found that the crank to connecting rod angle is 88.21738° and the connecting rod angle is 18.60647° from vertical (see Piston motion equations#Example). When the crank is driven by the connecting rod, a problem arises when the crank is at top dead centre (0°) or bottom dead centre (180°). At these ...
For rod length 6" and crank radius 2" (as shown in the example graph below), numerically solving the acceleration zero-crossings finds the velocity maxima/minima to be at crank angles of ±73.17615°. Then, using the triangle law of sines, it is found that the rod-vertical angle is 18.60647° and the crank-rod angle is 88.21738°. Clearly, in ...
A return connecting rod, [1] [2] return piston rod [i] or (in marine parlance) double piston rod engine [2] or back-acting engine is a particular layout for a steam engine. The key attribute of this layout is that the piston rod emerges from the cylinder to the crosshead , but the connecting rod then reverses direction and goes backwards to the ...
Bare cylinder block of a V8 engine Piston, piston ring, gudgeon pin and connecting rod The base of a reciprocating internal combustion engine is the engine block , which is typically made of cast iron (due to its good wear resistance and low cost) [ 22 ] or aluminum .
