Plenty and Son

Last updated

Plenty and Son of Eagle Ironworks, Newbury, Berkshire, England, was an engineering company specialising in marine steam engines. The company was founded in 1800. [1] In 1928, the company started to manufacture diesel engines under the name Plenty-Still, at Kings Road, Newbury. [2] In 1932, the diesel engine business became a separate company named the Newbury Diesel Company. The Plenty name is now owned by SPX FLOW.

Steam engine Heat engine that performs mechanical work using steam as its working fluid

A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force is transformed, by a connecting rod and flywheel, into rotational force for work. The term "steam engine" is generally applied only to reciprocating engines as just described, not to the steam turbine.

Diesel engine Internal combustion engine with quality rotational frequency governing, internal mixture formation, lean air-fuel-ratio, diffusion flame and compression ignition

The Diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel, which is injected into the combustion chamber, is caused by the elevated temperature of the air in the cylinder due to the mechanical compression. Diesel engines work by compressing only the air. This increases the air temperature inside the cylinder to such a high degree that atomised Diesel fuel injected into the combustion chamber ignites spontaneously. With the fuel being injected into the air just before combustion, the dispersion of the fuel is uneven; this is called a heterogenous air-fuel mixture. The process of mixing air and fuel happens almost entirely during combustion, the oxygen diffuses into the flame, which means that the Diesel engine operates with a diffusion flame. The torque a Diesel engine produces is controlled by manipulating the air ratio; this means, that instead of throttling the intake air, the Diesel engine relies on altering the amount of fuel that is injected, and the air ratio is usually high.
