complex multimodal regional, national and international hub for passenger and freight traffic

Los Angeles has a complex multimodal transportation infrastructure, which serves as a regional, national and international hub for passenger and freight traffic. The system includes the United States’ largest port complex; an extensive freight and passenger rail infrastructure, including light rail lines and subway lines; numerous airports and bus lines; Transportation Network Companies; and an extensive freeway and road system. People in Los Angeles rely on cars as the dominant mode of transportation,[1] but since 1990 Los Angeles Metro Rail has built over one hundred miles (160 km) of light and heavy rail serving more and more parts of Los Angeles.

Alternator (silver) mounted on a V8 engine

Alternators are used in modern automobiles to charge the battery and to power the electrical system when its engine is running.

Until the 1960s, automobiles used DC dynamo generators with commutators. With the availability of affordable silicon diode rectifiers, alternators were used instead. This was encouraged by the increasing electrical power required for cars in this period, with increasing loads from larger headlamps, electric wipers, heated rear windows and other accessories.

History[edit]

The modern type of vehicle alternators were first used by the military from WWII, to power radio equipment on specialist vehicles.[i] Post-war, other vehicles with high electrical demands, such as ambulances and radio taxis, could also be fitted with optional alternators.[1]

Alternators were first introduced as standard equipment on a production car by the Chrysler Corporation on the Valiant in 1960, several years ahead of Ford

Automotive design – Wikipedia

putri titian 3 months ago

Automotive design is the process of developing the appearance, and to some extent the ergonomics, of motor vehicles, including automobiles, motorcycles, trucks, buses, coaches, and vans.

The functional design and development of a modern motor vehicle is typically done by a large team from many different disciplines included within automotive engineering, however, design roles are not associated with requirements for Professional or Chartered-Engineer qualifications. Automotive design in this context is primarily concerned with developing the visual appearance or aesthetics of the vehicle, though it is also involved in the creation of the product concept. Automotive design as a professional vocation[1] is practiced by designers who may have an art background and a degree in industrial design or transportation design.
Terminology used in the field is found in the glossary of automotive design.
