Automobile Ancillary Power
] Automobile accessory power can be transferred by several different means. However, it is always ultimately derived from the automobile's engine, internal combustion engine, battery, or other "prime mover" source of energy. The advent of high-powered batteries in hybrid and all-electrical vehicles is shifting the balance of technologies even further in the direction of electrically powered accessories. An engine has one or more devices for converting energy it produces into a usable form, electrical, electricity connection through the alternator, hydraulic connections from a pump or engine system, Pneumatics, compressed air, and engine vacuum; or the engine may be directly tapped through a Machine, mechanical connection. Modern vehicles run most accessories on electrical power. Typically, only 2% of a vehicle's total power output has gone towards powering accessories. Electrical and hybrid vehicles may use a larger proportion of energy for accessories, due to reduced inefficienc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Energy Flows In Car
In physics, energy (from Ancient Greek: wikt:ἐνέργεια#Ancient_Greek, ἐνέργεια, ''enérgeia'', “activity”) is the physical quantity, quantitative physical property, property that is #Energy transfer, transferred to a physical body, body or to a physical system, recognizable in the performance of Work (thermodynamics), work and in the form of heat and light. Energy is a Conservation law, conserved quantity—the law of conservation of energy states that energy can be Energy transformation, converted in form, but not created or destroyed. The unit of measurement for energy in the International System of Units (SI) is the joule (J). Common forms of energy include the kinetic energy of a moving object, the potential energy stored by an object (for instance due to its position in a Classical field theory, field), the elastic energy stored in a solid object, chemical energy associated with chemical reactions, the radiant energy carried by electromagnetic radiat ...

Kerosene Lamp
A kerosene lamp (also known as a paraffin lamp in some countries) is a type of lighting device that uses kerosene as a fuel. Kerosene lamps have a wick or mantle as light source, protected by a glass chimney or globe; lamps may be used on a table, or hand-held lanterns may be used for portable lighting. Like oil lamps, they are useful for lighting without electricity, such as in regions without rural electrification, in electrified areas during power outages, at campsites, and on boats. There are three types of kerosene lamp: flat-wick, central-draught (tubular round wick), and mantle lamp. Kerosene lanterns meant for portable use have a flat wick and are made in dead-flame, hot-blast, and cold-blast variants. Pressurized kerosene lamps use a gas mantle; these are known as Petromax, Tilley lamps, or Coleman lamps, among other manufacturers. They produce more light per unit of fuel than wick-type lamps, but are more complex and expensive in construction and more complex ...

Windshield Wiper
A windscreen wiper, windshield wiper, wiper blade (American English), or simply wiper, is a device used to remove rain, snow, ice, washer fluid, water, or debris from a vehicle's front window. Almost all motor vehicles, including cars, trucks, buses, train locomotives, and watercraft with a cabin—and some aircraft—are equipped with one or more such wipers, which are usually a legal requirement. A wiper generally consists of a metal arm; one end pivots, and the other end has a long rubber blade attached to it. The arm is powered by a motor, often an electric motor, although pneumatic power is also used for some vehicles. The blade is swung back and forth over the glass, pushing water, other precipitation, or any other impediments to visibility from its surface. The speed is usually adjustable on vehicles made after 1969, with several continuous rates and often one or more ''intermittent'' settings. Most personal automobiles use two synchronized ''radial''-type ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Convertible (car)
A convertible or cabriolet () is a passenger car that can be driven with or without a roof in place. The methods of retracting and storing the roof vary among eras and manufacturers. A convertible car's design allows an open-air driving experience, with the ability to provide a roof when required. A potential drawback of convertibles is their reduced structural rigidity (requiring significant engineering and modification to counteract the effects of removing a car's roof). The majority of convertible roofs are of a folding construction framework with the actual top made from cloth or other fabric. Other types of convertible roofs include retractable hardtops (often constructed from metal or plastic) and detachable hardtops (where a metal or plastic roof is manually removed and often stored in the trunk). Terminology Other terms for convertibles include cabriolet, cabrio, drop top, drophead coupé, open two-seater, open top, rag top, soft top, spider, and spyder. Consisten ...

Cigarette Lighter Receptacle
An automobile auxiliary power outlet (also known as car cigarette lighter or auxiliary power outlet) in an automobile was initially designed to power an electrically heated cigarette lighter,LifeWire.com article''“From Car Cigarette Lighter To 12V Accessory Socket”''/ref> but became a de facto standard DC connector to supply electrical power for portable accessories used in or near an automobile directly from the vehicle's electrical system. Such include mobile phone chargers, cooling fans, portable fridges, electric air pumps, and power inverters. In most vehicles, at least one car outlet is present. Some vehicles may have more power outlets: usually one for the front passengers, one for the rear passengers and one for the luggage trunk. The voltage of the power outlet is usually near 12 V DC, and may be elevated between 13.5 V to 15 V while the engine is running. The 12 V power circuit is protected by a car fuse, often rated at 10 to 20 amperes, which amounts from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Power Steering
A power steering is a mechanical device equipped on a motor vehicle that helps drivers steer the vehicle by reducing steering effort needed to turn the steering wheel, making it easier for the vehicle to turn or maneuver at lower speeds. Hydraulic or electric actuators add controlled energy to the steering mechanism, so the driver can provide less effort to turn the steered wheels when driving at typical speeds, and reduce considerably the physical effort necessary to turn the wheels when a vehicle is stopped or moving slowly. Power steering can also be engineered to provide some artificial feedback of forces acting on the steered wheels. Hydraulic power steering systems for cars augment steering effort via an actuator, a hydraulic cylinder that is part of a servo system. These systems have a direct mechanical connection between the steering wheel and the linkage that steers the wheels. This means that power-steering system failure (to augment effort) still permits the vehicle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Power Door Locks
Power door locks (also known as electric door locks or central locking) allow the driver or front passenger to simultaneously lock or unlock all the doors of an automobile or truck, by pressing a button or flipping a switch. Power door locks were introduced on the luxury Scripps-Booth in 1914, but were not common on luxury cars until Packard reintroduced them in 1956. Nearly every car model today offers this feature as at least optional equipment. Early systems locked and unlocked only the car doors. Many cars today also feature systems which can unlock such things as the luggage compartment or fuel filler cap door. It is also common on modern cars for the locks to activate automatically when the car is put into gear or reaches a certain speed. Remote and handsfree In 1980, Ford Motor Company introduced an external keypad-type keyless entry system, wherein the driver entered a numeric combination —either pre-programmed at the factory or one programmed by the owner— to ...

Power Seat
A power seat in an automobile is a seat in a passenger compartment that can be adjusted using a button, switch or joystick and a set of small electric motors. Most cars with this feature have controls for the driver's seat only, though almost all luxury cars also have power controls for the front passenger seat. In addition to fore and aft adjustments, power seats can be raised or lowered and tilted to suit the comfort of the driver and/or passenger. Many power seats allow occupants to adjust the seat lumbar or seatback recline, all at the push of a button or flick of a switch. Cars which do not have this feature have a lever or bar to provide fore and aft adjustments. Memory seat Some cars also have memory adjustments, which can recall (usually) two different adjustments of the seat by pressing a button. The 1981 Cadillac was the first car to offer this feature in its modern version. By the 1990s, these systems began allowing customized settings and adjustments for such conveni ...

Power Window
Power windows or electric windows are automobile windows which can be raised and lowered by pressing a button or switch, as opposed to using a crank handle. History Packard had introduced hydraulic window lifts (power windows) in fall of 1940, for its new 1941 Packard 180 series cars. This was a hydro-electric system. In 1941, the Ford Motor Company followed with the first power windows on the Lincoln Custom (only the limousine and seven-passenger sedans). Cadillac had a straight-electric divider window (but not side windows) on their series 75. Power assists originated in the need and desire to move convertible body-style tops up and down by some means other than human effort. The earliest power assists were vacuum-operated and were offered on Chrysler Corporation vehicles, particularly the low-cost Plymouth convertibles in the late 1930s. Shortly before World War II, General Motors developed a central hydraulic pump for working convertible tops. This system was introd ...

42-volt Electrical System
In automobiles, a 42-volt electrical system was an electrical power standard proposed in the late 1990s. It was intended to allow more powerful electrically-driven accessories, and lighter automobile wiring harnesses. Electric motors were proposed to be used for power steering or other systems, providing more compact installations and eliminating the weight of drive belts or large wires for high-current loads. The proposed new standard was exactly triple the voltage of existing "12-volt" systems. The higher voltage was selected to provide greater power capacity for wiring and devices on one hand, and to stay under the 50-volt limit used as a guideline for electric shock hazard. The European auto manufacturer Daimler-Benz proposed a ''42V'' brand name for the conversion. Although many manufacturers were predicting a switch to 36-volt (lithium-ion battery) / 42-volt (charging voltage) electrical systems, the changeover has not occurred, and the plans appear to have been canceled.

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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plymouth Valiant
The Plymouth Valiant (first appearing in 1959 as simply the Valiant) is an automobile which was marketed by the Plymouth division of the Chrysler Corporation in the United States from the model years of 1960 through 1976. It was created to give the company an entry in the compact car market emerging in the late 1950s. The Valiant was also built and marketed, without the Plymouth brand, worldwide in countries including Argentina, Australia, Brazil, Canada, Finland, Mexico, New Zealand, South Africa, Sweden and Switzerland, as well as other countries in South America and Western Europe. It became well known for its excellent durability and reliability, and was one of Chrysler's best-selling automobiles during the 1960s and 1970s, helping to keep the company solvent during an economic downturn. ''Road & Track'' magazine considered the Valiant to be "one of the best all-around domestic cars". First generation (1960–1962) In May 1957, Chrysler president Lester Lum "Tex" Colbert e ...
