Arrow SNC
Arrow SNC was an Italian aircraft engine manufacturer based in Piacenza. The company specialized in the design and manufacture of two-stroke engines for ultralight and homebuilt aircraft. The company is no longer in business.Cliche, Andre: ''Ultralight Aircraft Shopper's Guide'' 8th Edition, page G-1 Cybair Limited Publishing, 2001. Purdy, Don: ''AeroCrafter - Homebuilt Aircraft Sourcebook'', page 70. BAI Communications. The company developed a series of engines that were of a modular design, with the same pistons, cylinders and gearboxes, but using different crankcases. These were assembled into single, twin and four-cylinder engines named for their displacements in cubic centimetres. The single cylinder Arrow 250 has a displacement of and puts out . From the 250 was developed the Arrow 270 AC, which has a displacement of and puts out . The twin cylinder Arrow 500 has a displacement of and puts out , while the four-cylinder Arrow 1000 has a displacement of and puts out ...

Privately Held Company
A privately held company (or simply a private company) is a company whose shares and related rights or obligations are not offered for public subscription or publicly negotiated in the respective listed markets, but rather the company's stock is offered, owned, traded, exchanged privately, or Over-the-counter (finance), over-the-counter. In the case of a closed corporation, there are a relatively small number of shareholders or company members. Related terms are closely-held corporation, unquoted company, and unlisted company. Though less visible than their public company, publicly traded counterparts, private companies have major importance in the world's economy. In 2008, the 441 list of largest private non-governmental companies by revenue, largest private companies in the United States accounted for ($1.8 trillion) in revenues and employed 6.2 million people, according to ''Forbes''.

Two Stroke
A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a 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) 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 Scottish engineer Dugald Clerk, who patented his design in 1881. However, unlike most later two-st ...

Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...

Quebec
Quebec ( ; )According to the Canadian government, ''Québec'' (with the acute accent) is the official name in Canadian French and ''Quebec'' (without the accent) is the province's official name in Canadian English is one of the thirteen provinces and territories of Canada. It is the largest province by area and the second-largest by population. Much of the population lives in urban areas along the St. Lawrence River, between the most populous city, Montreal, and the provincial capital, Quebec City. Quebec is the home of the Québécois nation. Located in Central Canada, the province shares land borders with Ontario to the west, Newfoundland and Labrador to the northeast, New Brunswick to the southeast, and a coastal border with Nunavut; in the south it borders Maine, New Hampshire, Vermont, and New York in the United States. Between 1534 and 1763, Quebec was called ''Canada'' and was the most developed colony in New France. Following the Seven Years' War, Quebec b ...

Montreal
Montreal ( ; officially Montréal, ) is the List of the largest municipalities in Canada by population, second-most populous city in Canada and List of towns in Quebec, most populous city in the Provinces and territories of Canada, Canadian province of Quebec. Founded in 1642 as ''Fort Ville-Marie, Ville-Marie'', or "City of Mary", it is named after Mount Royal, the triple-peaked hill around which the early city of Ville-Marie is built.

Cubic Centimetre
A cubic centimetre (or cubic centimeter in US English) (SI unit symbol: cm3; non-SI abbreviations: cc and ccm) is a commonly used unit of volume that corresponds to the volume of a cube that measures 1 cm × 1 cm × 1 cm. One cubic centimetre corresponds to a volume of one millilitre. The mass of one cubic centimetre of water at 3.98 °C (the temperature at which it attains its maximum density) is almost equal to one gram. In internal combustion engines, "cc" refers to the total volume of its engine displacement in cubic centimetres. The displacement can be calculated using the formula :d = \times b^2 \times s \times n where is engine displacement, is the bore of the cylinders, is length of the stroke and is the number of cylinders.

Piacenza
Piacenza (; egl, label= Piacentino, Piaṡëinsa ; ) is a city and in the Emilia-Romagna region of northern Italy, and the capital of the eponymous province. As of 2022, Piacenza is the ninth largest city in the region by population, with over 102,000 inhabitants. Westernmost major city of the region of Emilia-Romagna, it has strong relations with Lombardy, with which it borders, and in particular with Milan. It was once defined by Leonardo da Vinci as "Land of passage", in his Codex Atlanticus, by virtue of its crucial geographical location. Piacenza integrates characteristics of the nearby Ligurian and Piedmontese territories added to a prevalent Lombard influence, favored by communications with the nearby metropolis, which attenuate its Emilian footprint. Piacenza is located at a major crossroads at the intersection of Route E35/A1 between Bologna and Milan, and Route E70/A21 between Brescia and Turin. Piacenza is also at the confluence of the Trebbia, draining the north ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
