Volvo Engine Architecture
The Volvo Engine Architecture (VEA) is a family of straight-three and straight-four automobile petrol and diesel engines produced by Volvo Cars in Skövde, Sweden, since 2013, Zhangjiakou, China since 2016 and Tanjung Malim, Malaysia since 2022 by Proton. Volvo markets all engines under the ''Drive–E'' designation, while Geely groups the three-cylinder variants with its other engines under the ''G-power'' name. These engines are some of the few ever put into production as twincharged engines, in the company of the Lancia Delta Integrale and concept Jaguar CX-75. History Development of the new engine family began in 2006, with the decision to only produce four-cylinder engines being finalised in 2007. The intention was to produce smaller, more economical and environmentally friendly engines that would be fitted to every Volvo model. In 2008 Volvo began to upgrade its Skövde engine plant and invested roughly 2 billion SEK into development and tooling for the VEA. In the autumn ...

Volvo Cars
Volvo Cars ( sv, Volvo personvagnar, styled VOLVO in the company's logo) is a Swedish multinational manufacturer of luxury vehicles headquartered in Torslanda, Gothenburg. The company manufactures SUVs, station wagons, and sedans. The company's main marketing arguments are safety and its Swedish heritage and design. Volvo Cars has been separate from its former parent conglomerate and producer of heavy trucks, buses, and construction equipment (among others) AB Volvo since 1999 when AB Volvo sold its automobile division Volvo Cars to Ford Motor Company. In 2010, Ford sold loss-making Volvo Cars to the company Geely. Volvo Cars was publicly listed on the Nasdaq Stockholm stock exchange in 2021, though Geely still retains majority ownership. Volvo Cars and AB Volvo both share the Volvo logo, and cooperate in running the Volvo Museum. In March 2021, Volvo Cars announced that it would be a fully electric brand by 2030. In June 2021, Volvo Cars and Swedish battery developer and manuf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Automobile
A car or automobile is a motor vehicle with Wheel, wheels. Most definitions of ''cars'' say that they run primarily on roads, Car seat, seat one to eight people, have four wheels, and mainly transport private transport#Personal transport, people instead of cargo, goods. The year 1886 is regarded as the birth year of the car, when German inventor Carl Benz patented his Benz Patent-Motorwagen. Cars became widely available during the 20th century. One of the first cars affordable by the masses was the 1908 Ford Model T, Model T, an American car manufactured by the Ford Motor Company. Cars were rapidly adopted in the US, where they replaced Draft animal, animal-drawn carriages and carts. In Europe and other parts of the world, demand for automobiles did not increase until after World War II. The car is considered an essential part of the Developed country, developed economy. Cars have controls for driving, parking, passenger comfort, and a variety of lights. Over the decades, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Straight-four Engine
A straight-four engine (also called an inline-four) is a four-cylinder piston engine where cylinders are arranged in a line along a common crankshaft. The vast majority of automotive four-cylinder engines use a straight-four layout (with the exceptions of the flat-four engines produced by Subaru and Porsche) and the layout is also very common in motorcycles and other machinery. Therefore the term "four-cylinder engine" is usually synonymous with straight-four engines. When a straight-four engine is installed at an inclined angle (instead of with the cylinders oriented vertically), it is sometimes called a slant-four. Between 2005 and 2008, the proportion of new vehicles sold in the United States with four-cylinder engines rose from 30% to 47%. By the 2020 model year, the share for light-duty vehicles had risen to 59%. Design A four-stroke straight-four engine always has a cylinder on its power stroke, unlike engines with fewer cylinders where there is no power stroke occu ...

Selective Catalytic Reduction
Selective catalytic reduction (SCR) is a means of converting nitrogen oxides, also referred to as with the aid of a catalyst into diatomic nitrogen (), and water (). A reductant, typically anhydrous ammonia (), aqueous ammonia (), or a urea () solution, is added to a stream of flue or exhaust gas and is reacted onto a catalyst. As the reaction drives toward completion, nitrogen (), and carbon dioxide (), in the case of urea use, are produced. Selective catalytic reduction of using ammonia as the reducing agent was patented in the United States by the Engelhard Corporation in 1957. Development of SCR technology continued in Japan and the US in the early 1960s with research focusing on less expensive and more durable catalyst agents. The first large-scale SCR was installed by the IHI Corporation in 1978.Steam: Its Generation and Uses. Babcock & Wilcox. Commercial selective catalytic reduction systems are typically found on large utility boilers, industrial boilers, and munici ...

NOx Adsorber
A adsorber or trap (also called Lean trap, abbr. LNT) is a device that is used to reduce oxides of nitrogen (NO and NO2) emissions from a lean burn internal combustion engine by means of adsorption. Purpose and function of a adsorber A adsorber is designed to reduce oxides of nitrogen emitted in the exhaust gas of a lean burn internal combustion engine. Lean burn engines, particularly diesels, present a special challenge to emission control system designers because of the relatively high levels of O2 (atmospheric oxygen) in the exhaust gas. The 3-way catalytic converter that has been successfully used since the 1980s on stoichiometric engines (such as fueled by petrol, LPG, CNG, or ethanol) will not function at O2 levels in excess of 1.0%, and does not function well at levels above 0.5%. Because of the increasing need to limit emissions from diesel engines, technologies such as exhaust gas recirculation (EGR) and selective catalytic reduction (SCR) have been used, however EG ...

Diesel Particulate Filter
A diesel particulate filter (DPF) is a device designed to remove diesel particulate matter or soot from the exhaust gas of a diesel engine.Tom Nash (May 2003) "Diesels: The Smoke is clearing", ''Motor '' Vol.199 No. 5, p. 54, Hearst Business Publishing Inc. Mode of action Wall-flow diesel particulate filters usually remove 85% or more of the soot, and under certain conditions can attain soot removal efficiencies approaching 100%. Some filters are single-use, intended for disposal and replacement once full of accumulated ash. Others are designed to burn off the accumulated particulate either passively through the use of a catalyst or by active means such as a fuel burner which heats the filter to soot combustion temperatures. This is accomplished by engine programming to run (when the filter is full) in a manner that elevates exhaust temperature, in conjunction with an extra fuel injector in the exhaust stream that injects fuel to react with a catalyst element to burn off accumulat ...

Exhaust Gas Recirculation
In internal combustion engines, exhaust gas recirculation (EGR) is a nitrogen oxide () emissions reduction technique used in petrol/gasoline, diesel engines and some hydrogen engines. EGR works by recirculating a portion of an engine's exhaust gas back to the engine cylinders. The exhaust gas displaces atmospheric air and reduces in the combustion chamber. Reducing the amount of oxygen reduces the amount of fuel that can burn in the cylinder thereby reducing peak in-cylinder temperatures. The actual amount of recirculated exhaust gas varies with the engine operating parameters. In the combustion cylinder, is produced by high-temperature mixtures of atmospheric nitrogen and oxygen, and this usually occurs at cylinder peak pressure. In a spark-ignition engine, an ancillary benefit of recirculating exhaust gases via an external EGR valve is an increase in efficiency, as charge dilution allows a larger throttle position and reduces associated pumping losses.

Catalytic Converter
A catalytic converter is an exhaust emission control device that converts toxic gases and pollutants in exhaust gas from an internal combustion engine into less-toxic pollutants by catalyzing a redox reaction. Catalytic converters are usually used with internal combustion engines fueled by gasoline or diesel, including lean-burn engines, and sometimes on kerosene heaters and stoves. The first widespread introduction of catalytic converters was in the United States automobile market. To comply with the U.S. Environmental Protection Agency's stricter regulation of exhaust emissions, most gasoline-powered vehicles starting with the 1975 model year are equipped with catalytic converters. These "two-way" converters combine oxygen with carbon monoxide (CO) and unburned hydrocarbons (HC) to produce carbon dioxide (CO2) and water (H2O). Although two-way converters on gasoline engines were rendered obsolete in 1981 by "three-way" converters that also reduce oxides of nitrogen (); they ...

Partial Zero-emissions Vehicle
A partial zero-emission vehicle, in the United States, is an automobile that has zero evaporative emissions from its fuel system, has a 15-year (or at least 150,000-mile) warranty on its emission-control components, and meets SULEV tailpipe-emission standards. Definition and history In California, PZEVs have their own administrative category for low-emission vehicles. The category was made in a bargain between automakers and the California Air Resources Board (CARB), so that automobile makers could delay making mandated zero-emission vehicles (ZEVs)—battery electric and fuel-cell electric vehicles. The super-ultra-low-emission vehicle (SULEV) standard is more stringent than the ultra-low-emission vehicle (ULEV) and low-emission vehicle standards. All emissions-related components, including the electric-propulsion parts of hybrid electric vehicles, must be warranted for 15 years or 150,000 miles. Advanced Technology PZEVs (AT-PZEVs) are at least as "clean" as regular PZEVs. C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Super Ultra-low Emission Vehicle
Super ultra-low emissions vehicle (SULEV) is a U.S. classification for passenger vehicle emissions. The classification is based on producing 90% fewer emissions than the average gasoline-powered vehicle. The SULEV standard is stricter than the standard for LEV (low emission vehicle) and ULEV (ultra-low-emission vehicle), however not as strict as PZEV (partial zero-emissions vehicle) which meets the SULEV standard for tailpipe emissions, but has zero instead of reduced evaporative emissions. Japan also offers an SU-LEV classification, for vehicles that show a 75 percent reduction in emissions vis-à-vis the 2005 emissions standards. Examples Examples of vehicles delivering SULEV emissions performance include: *Honda Accord 2000-? *Honda Insight (CVT transmission models only) *Honda Civic Hybrid CVT transmission models only, AT-PZEV available in certain states * Honda Civic GX Natural Gas * Honda CR-Z (AT-PZEV) *Toyota Prius *Ford Focus SULEV * BMW SULEV 128i, 328i, 325i, 325Ci, ...

European Emission Standards
The European emission standards are vehicle emission standards for pollution from the use of new land surface vehicles sold in the European Union and EEA member states and the UK, and ships in EU waters. The standards are defined in a series of European Union directives staging the progressive introduction of increasingly stringent standards. , the standards do not include non-exhaust emissions such as particulates from tyres and brakes. Details of Euro 7 have been postponed to 12 October 2022. Background In the European Union, emissions of nitrogen oxides (), total hydrocarbon (THC), non-methane hydrocarbons (NMHC), carbon monoxide (CO) and particulate matter (PM) are regulated for most vehicle types, including cars, trucks (lorries), locomotives, tractors and similar machinery, barges, but excluding seagoing ships and aeroplanes. For each vehicle type, different standards apply. Compliance is determined by running the engine at a standardised test cycle. Non-co ...
