Toyota Alphard
The is a minivan produced by the Japanese automaker Toyota since 2002. It is available as a seven or eight-seater with petrol and hybrid engine options. Hybrid variants have been available since 2003, which incorporates Toyota's Hybrid Synergy Drive technology. It is Toyota's flagship minivan. The Alphard is primarily made for the Japanese market, but is also sold in many Asian countries, Belarus, Russia, and the Middle East. Similar to the Camry, it is often regarded as a luxury car in Southeast Asian markets. Since the second generation, a twin model called has also been available, which is marketed as a sportier alternative to the Alphard and exclusively marketed by the Netz Store dealership chain until 2020. Since 2019, a modified and more upscale version of the model has been sold as the Lexus LM. The vehicle was named after Alphard, the brightest star in the constellation Hydra. Until the third generation, the Alphard wears a special front emblem which depicts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toyota
is a Japanese Multinational corporation, multinational Automotive industry, automotive manufacturer headquartered in Toyota City, Aichi, Japan. It was founded by Kiichiro Toyoda and incorporated on August 28, 1937. Toyota is the List of manufacturers by motor vehicle production, largest automobile manufacturer in the world, producing about 10 million vehicles per year. The company was founded as a spinoff of Toyota Industries, a machine maker started by Sakichi Toyoda, Kiichiro's father. Both companies are now part of the Toyota Group, one of the largest conglomerates in the world. While still a department of Toyota Industries, the company developed its first product, the Toyota Type A engine, Type A engine, in 1934 and its first passenger car in 1936, the Toyota AA. After World War II, Toyota benefited from Japan's alliance with the United States to learn from American automakers and other companies, which gave rise to The Toyota Way (a management philosophy) and the Toyota ...

Constellation
A constellation is an area on the celestial sphere in which a group of visible stars forms Asterism (astronomy), a perceived pattern or outline, typically representing an animal, mythological subject, or inanimate object. The first constellations were likely defined in prehistory. People used them to relate stories of their beliefs, experiences, creation myth, creation, and mythology. Different cultures and countries invented their own constellations, some of which lasted into the early 20th century before today's constellations were internationally recognized. The recognition of constellations has changed significantly over time. Many changed in size or shape. Some became popular, only to drop into obscurity. Some were limited to a single culture or nation. Naming constellations also helped astronomers and navigators identify stars more easily. Twelve (or thirteen) ancient constellations belong to the zodiac (straddling the ecliptic, which the Sun, Moon, and planets all traver ...

Continuously Variable Transmission
A continuously variable transmission (CVT) is an automated Transmission (mechanical device), transmission that can change through a continuous range of gear ratios, typically resulting in better fuel economy in gasoline applications. This contrasts with other transmissions that provide a limited number of gear ratios in fixed steps. The flexibility of a CVT with suitable control may allow the engine to operate at a constant angular velocity while the vehicle moves at varying speeds. Thus, CVT has a simpler structure, longer internal component lifespan, and greater durability. Compared to traditional automatic transmissions, it offers lower fuel consumption and is more environmentally friendly. CVTs are used in cars, tractors, Side-by-side (vehicle), side-by-sides, motor scooters, snowmobiles, bicycles, and Heavy equipment, earthmoving equipment. The most common type of CVT uses two pulleys connected by a Belt (mechanical), belt or Chain drive, chain; however, several other desig ...

Automatic Transmission
An automatic transmission (AT) or automatic gearbox is a multi-speed transmission (mechanics), transmission used in motor vehicles that does not require any input from the driver to change forward gears under normal driving conditions. The 1904 Sturtevant "horseless carriage gearbox" is often considered to be the first true automatic transmission. The first mass-produced automatic transmission is the General Motors ''Hydramatic'' two-speed hydraulic automatic, which was introduced in 1939. Automatic transmissions are especially prevalent in vehicular drivetrains, particularly those subject to intense mechanical acceleration and frequent idle/transient operating conditions; commonly commercial/passenger/utility vehicles, such as buses and waste collection vehicles. Prevalence Vehicles with internal combustion engines, unlike electric vehicles, require the engine to operate in a narrow range of rates of rotation, requiring a gearbox, operated manually or automatically, to drive t ...

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 integer number of AC cycles. Synchronous motors use electromagnets as the stator of the motor which create a magnetic field that rotates in time with the oscillations of the 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. Doubly fed synchronous motors use independently-excited multiphase AC electromagnets for both rotor and stator. Synchronous and induction motors are the most widely used AC motors. Synchronous motors rotate at a rate locked to the line frequency since they do not rely on induction to produce the rotor's magnetic field. Induction motors require '' slip'': the rotor must rotate at a frequency slightly slower than th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hybrid Electric Vehicle
A hybrid electric vehicle (HEV) is a type of hybrid vehicle that couples a conventional internal combustion engine (ICE) with one or more electric engines into a hybrid vehicle drivetrain, combined propulsion system. The presence of the electric powertrain, which has inherently better energy conversion efficiency, is intended to achieve either better fuel economy in automobiles, fuel economy or better acceleration performance than a conventional vehicle. There is a variety of HEV types and the degree to which each functions as an electric vehicle (EV) also varies. The most common form of HEV is hybrid electric passenger cars, although hybrid electric trucks (pickup truck, pickups, tow trucks and tractors), buses, motorboats, and aircraft also exist. Modern HEVs use energy recovery technologies such as motor–generator units. and regenerative braking to recycle the vehicle's kinetic energy to electric energy via an alternator (automotive), alternator, which is energy storage, st ...

V6 Engine
A V6 engine is a six- cylinder piston engine where the cylinders and cylinder blocks share a common crankshaft and are arranged in a V configuration. The first V6 engines were designed and produced independently by Marmon Motor Car Company, Deutz Gasmotoren Fabrik and Delahaye. Engines built after World War II include the Lancia V6 engine in 1950 for the Lancia Aurelia, and the Buick V6 engine in 1962 for the Buick Special. The V6 layout has become the most common layout for six-cylinder automotive engines. Design Due to their short length, V6 engines are often used as the larger engine option for vehicles which are otherwise produced with inline-four engines, especially in transverse engine vehicles. A downside for luxury cars is that V6 engines produce more vibrations than straight-six engines. Some sports cars like the Porsche 911 use flat-six engines instead of V6 engines, due to their near perfect primary engine balance and lower centre of gravity (which ...

Toyota MZ Engine
The Toyota MZ engine family is a piston engine, piston V6 engine series. It was Toyota's second V6 engine after the Toyota VZ engine, VZ engine family, of which the MZ series succeeded it. The MZ family is a lightweight V6 engine of an all-aluminium design, using lightweight parts than the previous heavy-duty VZ block engines in an effort to lower production costs and decrease engine and reciprocating weight without sacrificing reliability. Toyota sought to enhance the drivability pattern of the engine (over the Toyota VZ engine#3VZ-FE, 3VZ-FE) at exactly 3000 rpm, since that was the typical engine speed for motors cruising on the highway. The result was less cylinder distortion coupled with the decreased weight of rotating assemblies, smoother operation at that engine speed, and increased engine efficiency. The MZ series has an aluminium engine block and aluminium alloy DOHC cylinder heads. The cylinders are lined with cast iron, and is of a closed deck design (no open spac ...

Straight-four Engine
A straight-four engine (also referred to as an inline-four engine) is a four-cylinder Reciprocating engine, piston engine where cylinders are arranged in a line along a common crankshaft. The 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-4 engine, 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 ...

Toyota AZ Engine
The Toyota AZ engine family is a straight-4 piston engine series. The AZ series uses an aluminium engine block with cast iron cylinder liners and aluminium DOHC cylinder head. The engine series features many advanced technologies including slant- squish combustion chambers, offset cylinder and crank centers, and the VVT-i continuously variable intake valve timing system. The aluminium engine measures long, wide, and tall. The cylinder block is an open-deck, midi-skirt die-cast aluminium type with cast-in iron liners and a die-cast aluminium lower crankcase and a stamped oil pan. The forged steel crankshaft is fully balanced with eight counterweights and supported by five main bearings. A helical gear pressed in No. 3 counterweight drives twin contra-rotating balance shafts in the shaft housing within the lower crankcase. The dual overhead camshafts are driven by a single-stage roller chain of pitch, enabling a narrow included valve angle of 27.5°. The camshafts act on ...

Toyota Previa (XR30)
The Toyota Previa, also known as the in Japan, and Toyota Tarago in Australia, is a minivan that was produced by Toyota from 1990 until October 2019 across three generations. The name "Previa" is derived from the Spanish for "preview", as Toyota saw the first Previa as a vehicle that would preview technologies used in future minivans. The Previa was the second largest minivan in Toyota's lineup in Japan after the bigger and more luxurious Alphard/Vellfire. __TOC__ First generation (XR10/XR20; 1990) The first generation, designed by Toyota designer Tokuo Fukuichi and Calty designer David Doyle in 1987 (patent filed 24 December 1987), was introduced on 27 January 1990, and had only one sliding side door for the rear passengers. It featured a mid-engined platform, where the inline-four cylinder gasoline-powered engine was installed almost flat beneath the front seats, canted at a 75-degree angle from vertical to the right, viewed from the rear of the vehicle. ...
