precombustion chamber [¦prē·kəm¦bəs·chən ‚chām·bər]

(mechanical engineering)

A small chamber before the main combustion space of a turbine or reciprocating engine in which combustion is initiated.

a cavity in a cylinder head of an internal combustion engine that is connected to the space above a piston (the combustion chamber) by one or more channels. The fuel enters and is partially burned in the precombustion chamber, which improves carburetion by regulating gas flows to the combustion chamber. The volume of a precombustion chamber is generally from 25 to 30 percent of the volume of the main combustion chamber.
