In an alternate piston engine, the connecting rod or conrod connects the piston to the crank or crankshaft. Together with the crank, they form a simple mechanism that converts the reciprocating movement into a rotating movement. The connecting rods can also convert the rotary motion into reciprocating motion. Historically, before the development of the engines, they were first used this way.
As a connecting rod is rigid, it can transmit a thrust or thrust and therefore the rod can rotate the crank through both halves of a revolution, ie push the piston and pull the piston. Previous mechanisms, such as chains, could only be pulled. In some two-stroke engines the connecting rod is only required to push.
Nowadays, the connecting rods are best known for their use in internal combustion piston engines, such as car engines. These are of a different design than previous forms of connecting rods, used in steam engines and steam locomotives.
