Sir Harry Ricardo
Sir Harry Ralph Ricardo (26 January 1885 – 18 May 1974) was an English engineer who was one of the foremost engine designers and researchers in the early years of the development of the internal combustion engine. Among his many other works, he improved the engines that were used in the first tanks, oversaw the research into the physics of internal combustion that led to the use of octane ratings, was instrumental in development of the sleeve valve engine design, and invented the Diesel "Comet" Swirl chamber that made high-speed diesel engines economically feasible. Early life Harry Ricardo was born at 13 Bedford Square, London, in 1885, the eldest of three children, and only son of Halsey Ricardo, the architect, and his wife Catherine Jane, daughter of Sir Alexander Meadows Rendel, a civil engineer. Ricardo was descended from a brother of the famous political economist David Ricardo, a Sephardi Jew of Portuguese origin. He was one of the first people in England to see an ...

London
London is the capital and largest city of England and the United Kingdom, with a population of just under 9 million. It stands on the River Thames in south-east England at the head of a estuary down to the North Sea, and has been a major settlement for two millennia. The City of London, its ancient core and financial centre, was founded by the Romans as '' Londinium'' and retains its medieval boundaries.See also: Independent city § National capitals The City of Westminster, to the west of the City of London, has for centuries hosted the national government and parliament. Since the 19th century, the name "London" has also referred to the metropolis around this core, historically split between the counties of Middlesex, Essex, Surrey, Kent, and Hertfordshire, which largely comprises Greater London, governed by the Greater London Authority.The Greater London Authority consists of the Mayor of London and the London Assembly. The London Mayor is distinguished fr ...

Diesel Engine
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so-called compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Diesel engines work by compressing only air, or air plus residual combustion gases from the exhaust (known as exhaust gas recirculation (EGR)). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites. With the fuel being injected into the air just before combustion, the dispersion of the fuel is une ...

Shoreham-by-Sea
Shoreham-by-Sea (often shortened to Shoreham) is a coastal town and port in West Sussex, England. The town is bordered to its north by the South Downs, to its west by the Adur Valley and to its south by the River Adur and Shoreham Beach on the English Channel. The town lies in the middle of the ribbon of urban development along the English south coast, approximately equidistant from the city of Brighton and Hove to the east and the town of Worthing to the west. Shoreham covers an area of and has a population of 20,547 (2011 census). History Old Shoreham dates back to pre-Roman times. St Nicolas' Church, Shoreham-by-Sea, St Nicolas' Church, inland by the River Adur, is partly Anglo-Saxon in its construction. The name of the town has an Old English origin.

Two-stroke
A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a Thermodynamic power cycle, power cycle with two strokes (up and down movements) of the piston during one power cycle, this power cycle being completed in one revolution of the crankshaft. A four-stroke engine requires four strokes of the piston to complete a power cycle during two crankshaft revolutions. In a two-stroke engine, the end of the combustion stroke and the beginning of the compression stroke happen simultaneously, with the intake and exhaust (or Scavenging (automotive), scavenging) functions occurring at the same time. Two-stroke engines often have a high power-to-weight ratio, power being available in a narrow range of rotational speeds called the power band. Two-stroke engines have fewer moving parts than four-stroke engines. History The first commercial two-stroke engine involving cylinder compression is attributed to Scotland, Scottish engineer Dugald Clerk, who pa ...

Laurence Pomeroy
Laurence Henry Pomeroy (1883–1941) was an English automotive engineer trained as a locomotive engineer and particularly interested in the introduction of light alloys into automotive applications. Early life Laurence Pomeroy was born in London and after leaving school started a four-year engineering course at the East London Technical College as a Whitworth Exhibitioneri.e. won a ''Whitworth Scholarship for the advancement of mechanical engineering''. A scholarship provided by Sir Joseph Whitworth and at the same time became a railway engineering apprentice at the North London Locomotive Works at Bow. Determined to "get on" in 1903 Pomeroy joined Humphreys & Co Civil Engineers in Victoria Street, London. From there he became a draughtsman with Thornycroft in Basingstoke before moving to Vauxhall Motors in Luton in 1905, where he became assistant to chief engineer Frederick Hodges.

Bertram Hopkinson
Bertram Hopkinson (11 January 1874 – 26 August 1918) was a British patent lawyer and Professor of Mechanism and Applied Mechanics at Cambridge University. In this position he researched flames, explosions and metallurgy and became a pioneer designer of the internal combustion engine. Hopkinson was born in Birmingham, in 1874, the son of John Hopkinson, an electrical engineer. He read law at Trinity College, Cambridge, and became a lawyer after his graduation. Following the death of his father, brother and two of his sisters in a mountaineering accident in 1898, Hopkinson switched to a career in engineering instead. In 1903, Hopkinson was elected to the Cambridge chair in mechanism and applied mechanics, and in 1910 he was elected a Fellow of the Royal Society. During World War I he was commissioned into the Royal Engineers, and opened a research establishment at Orford Ness where he and his team researched weapons, sights, and ammunition. In 1915, Hopkinson discovered a s ...

West Sussex
West Sussex is a county in South East England on the English Channel coast. The ceremonial county comprises the shire districts of Adur, Arun, Chichester, Horsham, and Mid Sussex, and the boroughs of Crawley and Worthing. Covering an area of 1,991 square kilometres (769 sq mi), West Sussex borders Hampshire to the west, Surrey to the north, and East Sussex to the east. The county town and only city in West Sussex is Chichester, located in the south-west of the county. This was legally formalised with the establishment of West Sussex County Council in 1889 but within the ceremonial County of Sussex. After the reorganisation of local government in 1974, the ceremonial function of the historic county of Sussex was divided into two separate counties, West Sussex and East Sussex. The existing East and West Sussex councils took control respectively, with Mid Sussex and parts of Crawley being transferred to the West Sussex administration from East Sussex. In the 2011 censu ...

Edburton
Edburton is a small village in West Sussex, England, on the road from Upper Beeding to Fulking. History The village's name means Ēadburg's ''tūn'', or settlement. Ēadburg is a woman's name, and it is sometimes claimed that it refers to Edburga of Winchester, a granddaughter of King Alfred the Great and daughter of his successor King Edward the Elder. In the Sussex dialect the village was called Aburton, as can be seen from the name of Aburton Farm, a farmstead now converted to housing. The church supposedly founded by this Edburga c. 940 at Edburton collapsed and was rebuilt in the late twelfth century on the same foundations. This indicates that there was a substantial population living where there are only a few houses now. The situation at the foot of the north-facing South Downs escarpment provided a year-round supply of clean spring water from the chalk of the downs. The geology of Edburton varies. Farmers benefitted from the fertile and easily worked sandstones such as ...

Lancing, West Sussex
Lancing is a large coastal village and civil parish in the Adur district of West Sussex, England, on the western edge of the Adur Valley. It occupies part of the narrow central section of the Sussex coastal plain between smaller Sompting to the west, larger Shoreham-by-Sea to the east, and the parish of Coombes to the north. Excluding definitive suburbs it may have the largest undivided village cluster in Britain. However, its economy is commonly analysed as integral to the Brighton/Worthing/Littlehampton conurbation. Its settled area beneath the South Downs National Park covers , the majority of its land. It is a mix of no more than mid-rise coastal urban homes and farms and wildlife reserves on northern chalk downs. The oldest non-religious buildings date to around 1500 CE. The 2002 population was around 19,000, being measured at 18,810 in the 2011 Census.

Portuguese People
The Portuguese people () are a Romance nation and ethnic group indigenous to Portugal who share a common culture, ancestry and language. The Portuguese people's heritage largely derives from the pre-Celts, Proto-Celts (Lusitanians, Conii) and Celts (Gallaecians, Turduli and Celtici), who were Romanized after the conquest of the region by the ancient Romans. A small number of male lineages descend from Germanic tribes who arrived after the Roman period as ruling elites, including the Suebi, Buri, Hasdingi Vandals, Visigoths with the highest incidence occurring in northern and central Portugal. The pastoral Caucasus' Alans left small traces in a few central-southern areas. Finally, the Umayyad conquest of Iberia also left Jewish, Moorish and Saqaliba genetic contributions, particularly in the south of the country. The Roman Republic conquered the Iberian Peninsula during the 2nd and 1st centuries B.C. from the extensive maritime empire of Carthage during the series o ...

Sephardic Jewish
Sephardic (or Sephardi) Jews (, ; lad, Djudíos Sefardíes), also ''Sepharadim'' , Modern Hebrew: ''Sfaradim'', Tiberian: Səp̄āraddîm, also , ''Ye'hude Sepharad'', lit. "The Jews of Spain", es, Judíos sefardíes (or ), pt, Judeus sefarditas or Hispanic Jews, are a Jewish diaspora population associated with the Iberian Peninsula. The term, which is derived from the Hebrew ''Sepharad'' (), can also refer to the Mizrahi Jews of Western Asia and North Africa, who were also influenced by Sephardic law and customs. Many Iberian Jewish exiles also later sought refuge in Mizrahi Jewish communities, resulting in integration with those communities. The Jewish communities of the Iberian Peninsula prospered for centuries under the Muslim reign of Al-Andalus following the Umayyad conquest of Hispania, but their fortunes began to decline with the Christian ''Reconquista'' campaign to retake Spain. In 1492, the Alhambra Decree by the Catholic Monarchs of Spain called for the expulsi ...
