DIESEL ENGINEIntroductionThediesel engine(also known as acompression-ignition engine) is an internal combustion enginethat uses theheat of compression to initiateignitionand burn thefuelthat has been injected into thecombustion chamber. This contrasts with spark-ignition engines such as apetrol engine(gasoline engine) orgas engine(using a gaseous fuel as opposed togasoline), which use aspark plugto ignite an air-fuel mixture.HISTORYHERBERT AKROYD-STUARTIn 1885, he began investigating the possibility of using paraffin oil(very similar to modern-day diesel) for an engine.Hishot bulb engines, built from 1891 by Richard Hornsby, were the first internal combustion engine to use a pressurizedfuel injectionsystem.

In May 1890, he and Charles Richard Binney patented the modern Diesel engine incorporates the features of direct (airless) injection and compression-ignition.On 8 October 1890, he patented again detailing the working of a complete engine - essentially that of a diesel engine - where air and fuel are introduced separately.

RUDOLF DIESELIt was him who first patented the design and became the namesake for this type of engine technology.In 1893, his experiments created the first working model of a "new, efficient, thermal engine" which ran under its own power and developed a remarkable 26% fuel efficiency, more than double the then current standard set by steam engines.In February of 1897, Diesel introduced the first diesel engine which he felt could be put to practical use. It yielded an astonishing 75% fuel efficiency. The fuel he used at the Fair was peanut oil.Diesel's new engine technology gained world-wide acclaim in a relatively short time. Versions of his engines produced by his licensees were being used world-wide in mines of every description, oil fields, manufacturing industries, and in marine shipping.
