DeAct
Variable displacement is an automobile engine technology that allows the engine displacement to change, usually by deactivating cylinders, for improved fuel economy. The technology is primarily used in large, multi-cylinder engines. Many automobile manufacturers have adopted this technology as of 2005, although the concept has existed for some time prior to this. Theory of operation Cylinder deactivation is used to reduce the fuel consumption and emissions of an internal combustion engine during light-load operation. In typical light-load driving the driver uses only around 30 percent of an engine’s maximum power. In these conditions, the throttle valve is nearly closed, and the engine needs to work to draw air. This causes an inefficiency known as pumping loss. Some large capacity engines need to be throttled so much at light load that the cylinder pressure at top dead centre is approximately half that of a small 4-cylinder engine. Low cylinder pressure results in lower fuel eff ... [...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 ...

V12 Engine
A V12 engine is a twelve-cylinder piston engine where two banks of six cylinders are arranged in a V configuration around a common crankshaft. V12 engines are more common than V10 engines. However, they are less common than V8 engines. The first V12 engine was built in 1904 for use in racing boats. Due to the balanced nature of the engine and the smooth delivery of power, V12 engines were found in early luxury automobiles, boats, aircraft, and tanks. Aircraft V12 engines reached their apogee during World War II, following which they were mostly replaced by jet engines. In Formula One racing, V12 engines were common during the late 1960s and early 1990s. Applications of V12 engines in the 21st century have been as marine engines, in railway locomotives, as large stationary power as well as in some European sports and luxury cars. Design Balance and smoothness Each bank of a V12 engine essentially functions as a straight-six engine, which by itself has perfect primary and ...

Frankfurt Motor Show
The International Motor Show Germany or International Mobility Show Germany, in German known as the ''Internationale Automobil-Ausstellung'' (''IAA'' – International Automobile Exhibition), is one of the world's largest mobility shows. It consists of two separate fairs, that subdivided in 1991. While the ''IAA MOBILITY'' displays passenger vehicles, motorcycles and bikes, the ''IAA TRANSPORTATION'' specializes in commercial vehicles. Before the separation, the show was held solely at the Messe Frankfurt. The IAA is organized by the ''Verband der Automobilindustrie'' (VDA – Association of the German Automotive Industry) and is scheduled by the Organisation Internationale des Constructeurs d'Automobiles (OICA), who recognize the IAA as one of the "big five" (most prestigious auto shows worldwide). History In 1897 the first IAA was held at the Hotel Bristol in Berlin, with a total of eight motor vehicles on display. As the automobile became more known and accepted, the IAA bec ...

Alfa Romeo Alfetta
The Alfa Romeo Alfetta (Type 116) is a front-engine, five-passenger sedan and fastback coupé manufactured and marketed by Alfa Romeo from 1972 to 1987 with a production total over 400,000. The Alfetta was noted for the rear position of its transaxle (clutch and transmission) and its De Dion tube rear suspension — an arrangement designed to optimize handling by balancing front/rear weight distribution, as well as maintaining a low polar moment of inertia and low center of gravity. The interior of Coupé models featured a then unusual central tachometer placement — by itself, directly in front of the driver. The ''Alfetta'' name, which means "little Alfa" in Italian, derived from the nickname of the Alfa Romeo Tipo 159 Alfetta, a successful Formula One car which in its last (1951) iteration paired a transaxle layout to De Dion tube rear suspension — like its modern namesake. Design and dynamics The Alfetta introduced a new drivetrain layout to the marque. ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Alfa Romeo
Alfa Romeo Automobiles S.p.A. () is an Italian luxury car manufacturer and a subsidiary of Stellantis. The company was founded on 24 June 1910, in Milan, Italy. "Alfa" is an acronym of its founding name, "Anonima Lombarda Fabbrica Automobili." "Anonima" means "anonymous", which was a legal form of company at the time ( Società anonima). In the initial set-up phase, in order to have a building to produce cars, the company bought the Portello factory building of Darracq in Milan, which was closing up and selling all its assets. The brand is known for sport-oriented vehicles and has been involved in car racing since 1911. Alfa Romeo was owned by Fiat Chrysler Automobiles, the company that was responsible for the production of Alfa Romeo cars until its operations were fully merged with those of the PSA Group to form Stellantis on 16 January 2021. The first car produced by the company was the 1910 24 HP, designed by Giuseppe Merosi. A.L.F.A. ventured into motor racing, with driv ...

Engine Control Unit
An engine control unit (ECU), also commonly called an engine control module (ECM), is a type of electronic control unit that controls a series of actuators on an internal combustion engine to ensure optimal engine performance. It does this by reading values from a multitude of sensors within the engine bay, interpreting the data using multidimensional performance maps (called lookup tables), and adjusting the engine actuators. Before ECUs, air–fuel mixture, ignition timing, and idle speed were mechanically set and dynamically controlled by mechanical and pneumatic means. If the ECU has control over the fuel lines, then it is referred to as an electronic engine management system (EEMS). The fuel injection system has the major role of controlling the engine's fuel supply. The whole mechanism of the EEMS is controlled by a stack of sensors and actuators. Workings Control of air–fuel ratio Most modern engines use some type of fuel injection to deliver fuel to the cylinders. ...

Cadillac Seville
The Seville was manufactured by Cadillac from 1975 to 2004 as a smaller-sized, premium model. It was replaced by the STS in 2004. Origin of the name The name of "Cadillac's first small car" was selected over a revival of LaSalle or the GM design staff's preference, LaScala, primarily because, as noted by GM Marketing Director Gordon Horsburgh, "It had no negatives." The initial suggestion was "Leland" in honor of one of the make's founders but it was rejected because most buyers wouldn't understand the reference and Henry Leland had also founded rival Lincoln. Hundreds of suggestions were considered: after extensive research, LaSalle was the top pick with St. Moritz a distant second, trailed further by Seville. A troubled past (Lasalle) and difficult pronunciation (St.Moritz) led to selection of the ''Seville'' nameplate. Seville is the name of a Spanish province and its capital, renowned for its history and treasures of art and architecture. Cadillac had first used the nam ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
