Metromelt
A Metromelt is a self-propelled snowmelter machine. History They were first built in 1974 for the then Toronto Metro Roads and Works department to remove major snow accumulations from roads managed by Metro Toronto. Built by Trecan Combustion Limited of Hubley, Nova Scotia, the city operates a fleet of 5 machines (8 wheeled self driven (with driver cab) vehicles are stored at Toronto Works Ellesmere Yard in Scarborough) along with the 350-PD unpowered snowmelter trailer units by Trecan. Trecan Metromelt and snowmelters are used throughout Canada, the United States and Russia. Mobile self-propelled snowmelters were originally invented and patented in Canada, European Union and the US by Albert Z Morin, the original inventor of the Jet Melt and likewise renowned and honored by Canada's highest innovation award for inventing the aerodynamic mudflap.

Snowmelter
A snow melter is a piece of snow removal equipment designed to melt snow using flame burners, hot water or both. The melt-water is discharged into a storm drain or onto the ground. Melting snow artificially helps keep roads, airport tarmacs and other surfaces clear and ready to use, and the technology is primarily employed in areas where trucking snow is not geographically or economically feasible. A built-in snowmelt system which melts the snow where it falls is another snow removal alternative. Snow melters have been used since the 19th century. Comparison with dumping snow There are two main barriers to dumping snow, the cost and availability of land, and the cost and logistics of trucking snow. The dumping of snow into bodies of water is no longer allowed in many places for pollution reasons which leaves dumping the snow on land or melting the snow. The availability of land suitable for dumping is limited and in most urban areas, the cost of land is significant. Suitable ...

Metro Roads And Works
Toronto Transportation Services is the division of the City of Toronto which manages transport infrastructure within public rights of way in Toronto. With an operating budget of approximately $436.4 million in 2022 and 1,400 staff, the division maintains the city's surface streets and sidewalks, cycling infrastructure, the Gardiner Expressway and the Don Valley Parkway. History The department was created in the 1998 amalgamation of Toronto from the merger of: * Metropolitan Toronto Transportation Department (Metro Toronto Roads and Transportation) * North York Transportation Department * Scarborough Works Department * Etobicoke Transportation Department * City of York Transportation Department * East York Transportation Department * City of Toronto Department of Public Works and the Environment Before amalgamation, Metro Toronto Transportation was responsible for major roads across Metro, while the municipalities were responsible for collector and local roads in their respective ...

1970 Jet Melt
Year 197 ( CXCVII) was a common year starting on Saturday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Magius and Rufinus (or, less frequently, year 950 ''Ab urbe condita''). The denomination 197 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Metro Toronto
The Municipality of Metropolitan Toronto was an upper-tier level of municipal government in Ontario, Canada, from 1953 to 1998. It was made up of the old city of Toronto and numerous townships, towns and villages that surrounded Toronto, which were starting to urbanize rapidly after World War II. It was commonly referred to as "Metro Toronto" or "Metro". Passage of the 1997 ''City of Toronto Act'' caused the 1998 amalgamation of Metropolitan Toronto and its constituents into the current City of Toronto. The boundaries of present-day Toronto are the same as those of Metropolitan Toronto upon its dissolution: Lake Ontario to the south, Etobicoke Creek and Highway 427 to the west, Steeles Avenue to the north, and the Rouge River to the east. History City and suburbs Prior to the formation of Metropolitan Toronto, the municipalities surrounding the central city of Toronto were all independent townships, towns and villages within York County. After 1912, the city no longer ann ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Cylinder (engine)
In a reciprocating engine, the cylinder is the space in which a piston travels. The inner surface of the cylinder is formed from either a thin metallic liner (also called "sleeve") or a surface coating applied to the engine block. A piston is seated inside each cylinder by several metal piston rings, which also provide seals for compression and the lubricating oil. The piston rings do not actually touch the cylinder walls, instead they ride on a thin layer of lubricating oil. Steam engines The cylinder in a steam engine is made pressure-tight with end covers and a piston; a valve distributes the steam to the ends of the cylinder. Cylinders were cast in cast iron and later in steel. The cylinder casting can include other features such as valve ports and mounting feet. Internal combustion engines The cylinder is the space through which the piston travels, propelled to the energy generated from the combustion of the air/fuel mixture in the combustion chamber. In an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
