Dingolfing
Dingolfing is a town in southern Bavaria, Germany. It is the seat of the Landkreis (district) Dingolfing-Landau. Dingolfing is home of a BMW assembly plant. History The area now called Dingolfing was first mentioned in ''Tinguluinga'' in the year 833. In the year 1251 the duke of Bavaria, Otto II. awarded municipal rights to the town, which was the Upper City. The Lower City, around the church of St. John's, was an older settlement belonging to the Prince-Bishopric of Regensburg. By treaty of 1265 between Duke and Bishop, both cities were united. Dingolfing's large growth took place during the years of about 1315 to 1600. During this time the city prospered mostly through trade, fishing, leather craft and the production of wool cloths. The duke promoted these works, causing Dingolfing to prosper even more. The war of Austrian succession caused very heavy damage to the city and decimated the population by epidemics. The city became nothing more than debris and ash on May 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BMW S68
The BMW S68 is a twin-turbocharged V8 engine produced by BMW. It will be used for the first time in the 2022 revised BMW X7 as the M60i. A few weeks after its presentation, BMW showed a study of the XM with a more powerful version of the engine. In addition, the basic version is also used in the BMW 760i for the US market. Design The S68 has a stroke of and the same displacement as its predecessor, but the compression ratio of 10.5:1 corresponds to the higher compressed predecessor variants. It has one turbocharger per cylinder bank and both chargers are placed in the middle of the cylinder banks in a hot-vee design taken from the previous S63 variant; there is only one exhaust manifold. The engine oil is cooled by an external cooler, and a newly developed oil pump is used for the oil circuit.

Alternating Current
Alternating current (AC) is an electric current which periodically reverses direction and changes its magnitude continuously with time in contrast to direct current (DC) which flows only in one direction. Alternating current is the form in which electric power is delivered to businesses and residences, and it is the form of electrical energy that consumers typically use when they plug kitchen appliances, televisions, fans and electric lamps into a wall socket. A common source of DC power is a battery cell in a flashlight. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify '' current'' or ''voltage''. The usual waveform of alternating current in most electric power circuits is a sine wave, whose positive half-period corresponds with positive direction of the current and vice versa. In certain applications, like guitar amplifiers, different waveforms are used, such as triangular waves or square waves. Audio ...

Worldwide Harmonised Light Vehicles Test Procedure
The Worldwide harmonized Light vehicles Test Procedure (WLTP) is a global standard for determining the levels of pollutants, CO2 emissions and fuel consumption of traditional and hybrid cars, as well as the range of fully electric vehicles. The WLTP was adopted by the Inland Transport Committee of the United Nations Economic Commission for Europe (UNECE) as Addenda No. 15 to the Global Registry (Global Technical Regulations) defined by the 1998 Agreement. The standard is accepted by China, Japan, the United States and the European Union, among others. It aims to replace the previous and regional New European Driving Cycle ( NEDC) as the European vehicle homologation procedure. Its final version was released in 2015. One of the main goals of the WLTP is to better match the laboratory estimates of fuel consumption and emissions with the measures of an on-road driving condition. Since CO2 targets are becoming more and more important for the economic performance of vehicle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lithium-ion
A lithium-ion or Li-ion battery is a type of rechargeable battery which uses the reversible reduction of lithium ions to store energy. It is the predominant battery type used in portable consumer electronics and electric vehicles. It also sees significant use for grid-scale energy storage and military and aerospace applications. Compared to other rechargeable battery technologies, Li-ion batteries have high energy densities, low self-discharge, and no memory effect (although a small memory effect reported in LFP cells has been traced to poorly made cells). Chemistry, performance, cost and safety characteristics vary across types of lithium-ion batteries. Most commercial Li-ion cells use intercalation compounds as the active materials. The anode or negative electrode is usually graphite, although silicon-carbon is also being increasingly used. Cells can be manufactured to prioritize either energy or power density. Handheld electronics mostly use lithium polymer batterie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synchronous Motor
A synchronous electric motor is an AC electric motor in which, at steady state, the rotation of the shaft is synchronized with the frequency of the supply current; the rotation period is exactly equal to an integral number of AC cycles. Synchronous motors contain multiphase AC electromagnets on the stator of the motor that create a magnetic field which rotates in time with the oscillations of the line current. The rotor with permanent magnets or electromagnets turns in step with the stator field at the same rate and as a result, provides the second synchronized rotating magnet field of any AC motor. A synchronous motor is termed ''doubly fed'' if it is supplied with independently excited multiphase AC electromagnets on both the rotor and stator. The synchronous motor and the induction motor are the most widely used types of AC motors. The difference between the two types is that the synchronous motor rotates at a rate locked to the line frequency since it does not rely on ...

Automatic Transmission
An automatic transmission (sometimes abbreviated to auto or AT) is a multi-speed transmission (mechanics), transmission used in internal combustion engine-based motor vehicles that does not require any input from the driver to change forward gears under normal driving conditions. It typically includes a transmission, axle, and Differential (mechanical device), differential in one integrated assembly, thus technically becoming a transaxle. The most common type of automatic transmission is the #Hydraulic automatics, hydraulic automatic, which uses a planetary gearset, Hydraulic machinery, hydraulic controls, and a torque converter. Other types of automatic transmissions include continuously variable transmissions (CVT), automated manual transmissions (AMT), and dual-clutch transmissions (DCT). An electronic automatic transmission (EAT) may also be called an electronically controlled transmission (ECT), or electronic automatic transaxle (EATX). A hydraulic automatic transmission may ...

Plug-in Hybrid
A plug-in hybrid electric vehicle (PHEV) is a hybrid electric vehicle whose battery pack can be recharged by plugging a charging cable into an external electric power source, in addition to internally by its on-board internal combustion engine-powered generator. Most PHEVs are passenger cars, but there are also PHEV versions of commercial vehicles and vans, utility trucks, buses, trains, motorcycles, mopeds, and even military vehicles. Similar to all-electric vehicles (BEVs), PHEVs displace greenhouse gas emissions from the car tailpipe exhaust to the power station generators powering the electricity grid. These centralized generators may be of renewable energy (e.g. solar, wind or hydroelectric) and largely emission-free, or have an overall lower emission intensity than individual internal combustion engines. Compared to conventional hybrid electric vehicles (HEVs), PHEVs have a larger battery pack that can be charged from the power grid, which is also more eff ...

Mild Hybrid
Mild hybrids (also known as power-assist hybrids, battery-assisted hybrid vehicles or BAHVs) are generally cars with an internal combustion engine equipped with an electric machine (one motor/generator in a parallel hybrid configuration) allowing the engine to be turned off whenever the car is coasting, braking, or stopped, and then quickly restarted once power is again required. Mild hybrids may employ regenerative braking and some level of power assist to the internal combustion engine (ICE), but mild hybrids do not have an electric-only mode of propulsion. Overview The mild hybrid's electric motor provides greater efficiency through the use of a single device that is essentially an integrated starter/alternator sometimes known as a generator-motor unit. A typical mild-hybrid setup uses a belt-powered generator-motor unit driven off the engine to supply power to a small battery. The generator is also powered through regenerative braking, enabling power that would otherwise be ... [...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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
