Productinformatie

Huygens Gunpowder Engine :- The earliest internal combustion can be credited to famous Dutch physicist Christian Huygens (1629-1695) in the year 1680. Huygens engine employing gunpowder.

Four Stroke Cycle :- All the engines developed uptil 1860 provided combustion of the charge at about atmospheric pressure. In 1862, Beau de Rochas, a Frenchmen, wrote a paper describing the fundamental principals for efficient operation of piston combustion engine, which were demonstrated in a practical engine by Otto, a German engineer. This laid the foundation of four stroke cycle engine which is used till today in all four stroke spark-ignition engines. This method of operation was explained in the four operations as follows.

1st Stroke :- Induction of charge during the outward stroke of piston.

2nd Stroke :- Compression of the charge during inward stroke of the piston. 3rd Stroke :- Ignition of the air fuel mixture during inward dead centre, followed by

expansion during the next outward stroke of the piston.

4th Stroke :- Exhaust during the next inward stroke of the piston.

The Diesel Engine (1892) :-

The term diesel engine is used throughout the world to denote compression-ignition oil engines, two stroke or four stroke, with air less fuel injection. This very important concept of compression-ignition can be credited to Rudolf Diesel (1858-1913), a German engineer born in Paris. In 1892 he proposed compression of air alone until a sufficient high temperature was attained to ignite the fuel which was to be injected at the end of the compression stroke. In his first experiments he tries to injects coal dust into a cylinder containing air that had already been highly compressed.

MODERN DEVELOPMENT

Wankel Engine (1957)Dr Felix Wankel was born on August 13th 1902 in Swabia, Germany. He invented basic design that led to the eventual development of the first successful rotary engine. Wankels first rotary engine was tested at NSU, Germany in 1957.
