New Cars Technologies: Engines that run on hydrogen have been tested. Hydrogen combustion produces only a trace of harmful emissions, no carbon dioxide, and a water-vapor by-product. However, technical problems related to the gas’s density and flammability remain to be solved. New Cars Technologies Truck: Truck, motor vehicle designed primarily for hauling cargo or for special work or service purposes. Trucks are usually larger and heavier than automobiles and differ in basic construction. Most modern automobiles have a unibody construction, in which the body itself provides structural support for the vehicle. Trucks, by comparison, are built around a strong metal frame, called a chassis, that supports the rest of the truck. Trucks usually have larger, more powerful engines and stronger suspensions than automobiles have. Large trucks have additional axles and wheels for carrying heavy loads. Truck Public Transportation: Public Transportation, transportation service that is available to the general public and that carries passengers to destinations for a fee. Public transportation is also known as mass transportation or mass transit, since many people use it to travel to common destinations. Although many different types of public transportation systems exist, they can be classified into two main types: common carriers and contract carriers. Public Transportation Automobile Industry: Automobile Industry, industry that produces automobiles and other gasoline-powered vehicles, such as buses, trucks, and motorcycles. The automobile industry is one of the most important industries in the world, affecting not only the economy but also the cultures of the world. It provides jobs for millions of people, generates billions of dollars in worldwide revenues, and provides the basis for a multitude of related service and support industries. Automobiles revolutionized transportation in the 20th century, changing forever the way people live, travel, and do business. Automobile Industry Roads: Road, path established over land for the passage of vehicles, people, and animals. Roads provide dependable pathways for moving people and goods from one place to another. They range in quality from dirt paths to concrete-paved multilane highways. Roads Automobile Information:Automobile, self-propelled vehicle used primarily on public roads but adaptable to other surfaces. Automobiles changed the world during the 20th century, particularly in the United States and other industrialized nations. From the growth of suburbs to the development of elaborate road and highway systems, the so-called horseless carriage has forever altered the modern landscape. The manufacture, sale, and servicing of automobiles have become key elements of industrial economies. But along with greater mobility and job creation, the automobile has brought noise and air pollution, and automobile accidents rank among the leading causes of death and injury throughout the world. But for better or worse, the 1900s can be called the Age of the Automobile, and cars will no doubt continue to shape our culture and economy well into the 21st century.
Automobiles are powered and controlled by a complicated interrelationship between several systems. This diagram shows the parts of a car with a gas engine and manual transmission (the air filter and carburetor have been removed to show the parts beneath but usually appear in the space above the intake manifold). The major systems of the automobile are the power plant, the power train, the running gear, and the control system. Each of these major categories include a number of subsystems, as shown here. The power plant includes the engine, fuel, electrical, exhaust, lubrication, and coolant systems. The power train includes the transmission and drive systems, including the clutch, differential, and drive shaft. Suspension, stabilizers, wheels, and tires are all part of the running gear, or support system. Steering and brake systems are the major components of the control system, by which the driver directs the car.
