Engine knocking
An undesirable sound and phenomenon that occurs when the air-fuel mixture in the combustion chamber ignites prematurely or unevenly
Erosion
The destruction of metal or alloy by mechanical damage
Rigidity
A property that allows materials not to bend easily
Ores
Rocks from which metals can be extracted
Cavitation
The formation of water vapor bubbles that damage metal components of a centrifugal pump when they collapse back to the liquid phase
Impeller
The rotating part of a pump or other machine designed to move a fluid by rotation.
Mechanical Engineering
The branch of engineering that deals with machines and mechanics
Definition of the problem
The most critical step in a design process in which the problem is stated, normally in a problem statement.
Clutch
A component of an automobile system which cuts off the transmission rotation from the engine to the drivetrain
Bumper
A usually metal or rubber bar attached to either end of the car to absorb impact in a collision
Spark plug
A device inserted in the head of an internal-combustion engine cylinder that ignites the fuel mixture by means of an electric spark.
Piston
A solid cylinder or disk that fits snugly into a larger cylinder and moves under fluid pressure, as in a reciprocating engine, or displaces or compresses fluids, as in pumps and compressors.
CAM
An eccentric or multiply curved wheel mounted on a rotating shaft, used to produce variable or reciprocating motion in another engaged or contacted part.
Combustion chamber
An enclosed space in which combustion takes place, such as the space above the piston in the cylinder head of an internal-combustion engine or the chambers in a gas turbine or rocket engine in which fuel and oxidant burn
Oil pan
The bottom of the crankcase in an internal-combustion engine, serving as an oil reservoir.
Radiator
A device for cooling an internal-combustion engine, consisting of thin-walled tubes through which water passes. Heat is transferred from the water through the walls of the tubes to the airstream, which is created either by the motion of the vehicle or by a fan
Coolant
An agent that produces cooling, especially a fluid that draws off heat by circulating through an engine or by bathing a mechanical part.
System
The entire combination of hardware, Information, and people needed to accomplish some specified missions.
