Hybrid Electric Buses
A hybrid electric bus is a bus that combines a conventional internal combustion engine propulsion system with an electric propulsion system. These type of buses normally use a Diesel-electric powertrain and are also known as hybrid Diesel-electric buses. The introduction of hybrid electric vehicles and other green vehicles for purposes of public transport forms a part of sustainable transport schemes. Powertrain Types of hybrid vehicle drivetrain A hybrid electric bus may have either a parallel powertrain (e.g. Volvo B5LH) or a series powertrain (e.g. some versions of the Alexander Dennis Enviro400 MMC). Plug-in hybrid A plug-in hybrid school bus effort began in 2003 in Raleigh, NC when Advanced Energy began working between districts across the country and manufacturers to understand the needs of both. The effort demonstrated both a technical and business feasibility and as a result was able to secure funding in 2005 froNASEOto purchase up to 20 buses. The resulting R ...

Dual-mode Bus
A dual-mode bus is a bus that can run independently on power from two different sources, typically electricity from overhead lines like a trolleybus or from batteries like a hybrid bus, alternated with conventional fossil fuel (generally diesel fuel). In contrast to other hybrid buses, dual-mode buses can run forever exclusively on their electric power source (wires). Several of the examples listed below involve the use of dual-mode buses to travel through a tunnel on electric overhead power. Many modern trolleybuses are equipped with auxiliary propulsion systems, either using a small diesel engine or battery power, allowing movement away from the overhead wires, called "off-wire" movement, but such vehicles are generally not considered to be dual-mode buses if their off-wire capability is very limited. Examples include the fleet of about 300 trolleybuses in San Francisco and the trolleybuses used on a 2005-opened system in Rome, Italy,Webb, Mary (ed.) (2009). ''Jane's Urban Tra ...

QuayLink
QuayLink was a bus service in Tyne and Wear, England, which connected Gateshead and Newcastle upon Tyne, and later North Tyneside, with the Quayside. Funded by the Tyne and Wear Passenger Transport Executive, the service was launched on 22 July 2005. Operated initially by Stagecoach North East, the service was transferred to Go North East in July 2010 – later being operated commercially from July 2015, following budget cuts. History QuayLink was designed as a frequent, high quality bus service, for the newly developed and expanding Quayside area. Despite being located a short distance from the town centre of Gateshead and city centre of Newcastle upon Tyne, the area was poorly served by public transport. In June 2002, both Gateshead Council and Newcastle City Council, along with the Tyne and Wear Passenger Transport Executive, invited tenders for operation of a proposed Tyne Quayside Link, as well as the manufacture of eight alternatively-fuelled buses. The proposed project ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gas Turbine
A gas turbine, also called a combustion turbine, is a type of continuous flow internal combustion engine. The main parts common to all gas turbine engines form the power-producing part (known as the gas generator or core) and are, in the direction of flow: * a rotating gas compressor * a combustor * a compressor-driving turbine. Additional components have to be added to the gas generator to suit its application. Common to all is an air inlet but with different configurations to suit the requirements of marine use, land use or flight at speeds varying from stationary to supersonic. A propelling nozzle is added to produce thrust for flight. An extra turbine is added to drive a propeller (turboprop) or ducted fan (turbofan) to reduce fuel consumption (by increasing propulsive efficiency) at subsonic flight speeds. An extra turbine is also required to drive a helicopter rotor or land-vehicle transmission (turboshaft), marine propeller or electrical generator (power turbine). Greater ...

Environmental Performance Vehicles
Environmental Performance Vehicles (EPV), previously DesignLine Corporation, is a manufacturer of coach, electric and range-extended electric (hybrid) buses. It was founded in Ashburton, New Zealand in 1985. Initially it was a manufacturer of tour coaches. In the 1990s it diversified into conventional transit buses and then added hybrid city buses in the late 1990s. It was acquired by American interests in 2006, and DesignLine Corporation's headquarters was relocated to Charlotte, North Carolina. Following a bankruptcy in 2013, the assets of DesignLine were sold and the company was renamed. EPV is no longer affiliated with the DesignLine operations in New Zealand, which was placed in liquidation in 2011 and then sold to a Malaysian-controlled joint business venture who operate it under the name DesignLine Bus Pacific, which was renamed Global Bus Ventures (NZ) on 30 May 2016. Bankruptcy As DesignLine, it filed for protection under chapter 11 of the United States Bankruptcy Court ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greenhouse Gas Emissions
Greenhouse gas emissions from human activities strengthen the greenhouse effect, contributing to climate change. Most is carbon dioxide from burning fossil fuels: coal, oil, and natural gas. The largest emitters include coal in China and large oil and gas companies, many state-owned by OPEC and Russia. Human-caused emissions have increased atmospheric carbon dioxide by about 50% over pre-industrial levels. The growing levels of emissions have varied, but it was consistent among all greenhouse gases (GHG). Emissions in the 2010s averaged 56 billion tons a year, higher than ever before. Electricity generation and transport are major emitters; the largest single source, according to the United States Environmental Protection Agency, is transportation, accounting for 27% of all USA greenhouse gas emissions. Deforestation and other changes in land use also emit carbon dioxide and methane. The largest source of anthropogenic methane emissions is agriculture, closely followed by ...

Biodiesel
Biodiesel is a form of diesel fuel derived from plants or animals and consisting of long-chain fatty acid esters. It is typically made by chemically reacting lipids such as animal fat (tallow), soybean oil, or some other vegetable oil with an alcohol, producing a methyl, ethyl or propyl ester by the process of transesterification. Unlike the vegetable and waste oils used to fuel converted diesel engines, biodiesel is a drop-in biofuel, meaning it is compatible with existing diesel engines and distribution infrastructure. However, it is usually blended with petrodiesel (typically to less than 10%) since most engines cannot run on pure Biodiesel without modification. Biodiesel blends can also be used as heating oil. The US National Biodiesel Board defines "biodiesel" as a mono-alkyl ester. Blends Blends of biodiesel and conventional hydrocarbon-based diesel are most commonly distributed for use in the retail diesel fuel marketplace. Much of the world uses a system know ...

Ultracapacitor
A supercapacitor (SC), also called an ultracapacitor, is a high-capacity capacitor, with a capacitance value much higher than other capacitors but with lower voltage limits. It bridges the gap between electrolytic capacitors and rechargeable batteries. It typically stores 10 to 100 times more energy per unit volume or mass than electrolytic capacitors, can accept and deliver charge much faster than batteries, and tolerates many more charge and discharge cycles than rechargeable batteries. Supercapacitors are used in applications requiring many rapid charge/discharge cycles, rather than long-term compact energy storage — in automobiles, buses, trains, cranes and elevators, where they are used for regenerative braking, short-term energy storage, or burst-mode power delivery. Smaller units are used as power backup for static random-access memory (SRAM). Unlike ordinary capacitors, supercapacitors do not use the conventional solid dielectric, but rather, they use electros ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
