An onboard refueling vapor recovery system (ORVR) is a vehicle fuel vapor emission control system that captures volatile organic compounds (VOC, potentially harmful vapors) during refueling. [1][page needed] There are two types of vehicle fuel vapor emission control systems: the ORVR, and the Stage II vapor recovery system. [2]
This was the first mass market system with controls on the dash and an electric clutch. [14] This system was also compact and serviceable with all of its components installed under the hood or in the cowl area. [15] Combining heating, cooling, and ventilating, the new air conditioning system for the Nash cars was called the "All-Weather Eye". [16]
Crankcase ventilation system. A crankcase ventilation system (CVS) removes unwanted gases from the crankcase of an internal combustion engine. The system usually consists of a tube, a one-way valve and a vacuum source (such as the inlet manifold). The unwanted gases, called "blow-by", are gases from the combustion chamber which have leaked past ...
Endovascular aneurysm repair (EVAR) is a type of minimally-invasive endovascular surgery used to treat pathology of the aorta, most commonly an abdominal aortic aneurysm (AAA). When used to treat thoracic aortic disease, the procedure is then specifically termed TEVAR for "thoracic endovascular aortic/aneurysm repair."

Smoke testing (mechanical) A sanitary sewer manhole in Springdale, Arkansas with smoke coming out as a result of smoke testing for leaks. Smoke testing refers to various classes of tests of systems, usually intended to determine whether they are ready for more robust testing. The expression probably was first used in plumbing in referring to ...
Vehicle emissions control is the study of reducing the emissions produced by motor vehicles, especially internal combustion engines. The primary emissions studied include hydrocarbons, volatile organic compounds, carbon monoxide, carbon dioxide, nitrogen oxides, particulate matter, and sulfur oxides. Starting in the 1950s and 1960s, various ...
A detailed inventory of greenhouse gas emissions from upstream oil and gas activities in Canada for the year 2000 estimated that fugitive equipment leaks had a global warming potential equivalent to the release of 17 million metric tonnes of carbon dioxide, or 12 percent of all greenhouse gases emitted by the sector, [9] while another report put fugitive emissions at 5.2% of world greenhouse ...
