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]
Air changes per hour, abbreviated ACPH or ACH, or air change rate is the number of times that the total air volume in a room or space is completely removed and replaced in an hour. If the air in the space is either uniform or perfectly mixed, air changes per hour is a measure of how many times the air within a defined space is replaced each ...
The mixing plenum normally combines two air streams, and includes for three sets of dampers: one for the fresh air, one for the exhaust air, and a mixing damper between the two air streams. [2] The mix of fresh air and recirculated air can thus be adjusted to suit the needs of the building's occupants. Most systems will use motorized dampers to ...
A pump, manufactured by Dresser Wayne, in Greece. A dispenser being used at a BP gas station in Wisconsin. [ 1] A gasoline pump or fuel dispenser is a machine at a filling station that is used to pump gasoline (petrol), diesel, or other types of liquid fuel into vehicles. Gasoline pumps are also known as bowsers or petrol bowsers (in Australia ...
A two-year demonstration program with 25 flexible-fuel plug-in minivans began in April 2012. The first Town and Country were delivered in Auburn Hills, Michigan and Charlotte, North Carolina. The US$26-million demonstration project is partially financed by a US$10 million grant from the U.S. Department of Energy (DOE).
Fuel pump. A fuel pump is a component used in many liquid-fuelled engines (such as petrol/gasoline or diesel engines) to transfer the fuel from the fuel tank to the device where it is mixed with the intake air (such as the carburetor or fuel injector ). Carbureted engines often use low-pressure mechanical pumps that are mounted on the engine.
Air–fuel ratio (AFR) is the mass ratio of air to a solid, liquid, or gaseous fuel present in a combustion process. The combustion may take place in a controlled manner such as in an internal combustion engine or industrial furnace, or may result in an explosion (e.g., a dust explosion),The air–fuel ratio determines whether a mixture is combustible at all, how much energy is being released ...
National Transportation Safety Board chair Jennifer Homendy said staff at the agency would like to complete its probe into the Jan. 5 Alaska Airlines Boeing 737 MAX 9 mid-air emergency by early ...
