The trucking industry provides an essential service to the American economy by transporting large quantities of raw materials, works in process, and finished goods over land—typically from manufacturing plants to retail distribution centers. Trucks are also important to the construction industry, as dump trucks and portable concrete mixers are necessary to move the large amounts of rocks, dirt, concrete, and other building materials used in construction. Trucks in America are responsible for the majority of freight movement over land, and are vital tools in the manufacturing, transportation, and warehousing industries.
Large trucks and buses require a commercial driver's license (CDL) to operate. Obtaining a CDL requires extra education and training dealing with the special knowledge requirements and handling characteristics of such a large vehicle. Drivers of CMVs must adhere to the hours of service, which are regulations governing the driving hours of commercial drivers. These, and all other rules regarding the safety of interstate commercial driving, are issued by the Federal Motor Carrier Safety Administration (FMCSA). The FMCSA is also a division of the United States Department of Transportation (USDOT), which governs all transportation-related industries such as trucking, shipping, railroads, and airlines. Some other issues are handled by another branch of the USDOT, the Federal Highway Administration (FHWA).
The Ram (formerly the Dodge Ram) is a full-size pickup truck manufactured by Chrysler Group LLC. As of 2010, it has been sold under the Ram Trucks brand. Previously, Ram was part of the Dodge lineup of light trucks. The name Ram was first used in 1981 on the redesigned Ram and Power Ram following the retiring and rebadging of the Dodge D Series pickup trucks as well as B-series vans. The truck is named for the Ram hood ornament that first appeared on Dodge vehicles in 1933. The Ram Truck is in its fourth generation as of the 2009 model year.
Ram trucks have been named Motor Trend magazine's Truck of the Year four times; the second-generation Ram won the award in 1994, the third-generation Ram Heavy Duty won the award in 2003, the fourth-generation Ram Heavy Duty won in 2010 and the current Ram 1500 won in 2013. The Ram is currently built at the Saltillo Truck Assembly in Saltillo, Coahuila, Mexico and at the Warren Truck Assembly in Warren, Michigan, United States.
A diesel engine (also known as a compression-ignition engine) is an internal combustion engine that uses the heat of compression to initiate ignition and burn the fuel that has been injected into the combustion chamber. This contrasts with spark-ignition engines such as a petrol engine (gasoline engine) or gas engine (using a gaseous fuel as opposed to gasoline), which use a spark plug to ignite an air-fuel mixture. The engine was developed by German inventor Rudolf Diesel in 1893.
The diesel engine has the highest thermal efficiency of any standard internal or external combustion engine due to its very high compression ratio. Low-speed diesel engines (as used in ships and other applications where overall engine weight is relatively unimportant) can have a thermal efficiency that exceeds 50%.
The Cummins B Series is a family of straight-four and straight-6 diesel truck and industrial piston engines manufactured by Cummins. The B Series is known for the popular 3.9 litres (238.0 cu in) straight-four and 5.9 litres (360.0 cu in) straight-six motors. A 3.3 litres (201.4 cu in) straight-four is also available. The B Series is widely used in many segments, including pickup trucks (the Dodge Ram), buses, military vehicles, construction equipment, and marine. Some of the construction and marine applications have actually featured two B series Cummins engines. The engine was originally designed by Cummins and Case Corporation for commercial truck applications, and gained much of its popularity after appearing in the Dodge Ram, in 1989.
The D Series was a line of pickup trucks sold by the Dodge division of American automaker Chrysler from 1961-1980. After 1980, the trucks were renamed the Dodge Ram and the same basic design was retained until the 1994 introduction of a completely redesigned Ram. The D Series shared its AD platform with the Dodge Ramcharger/Plymouth Trailduster twins.
The body offered the then-traditional step-side bed, with distinct fenders as an option. As default, it introduced the first Virgil Exner-inspired "Swept-Line" bed where the bed was the width of the vehicle and the fenders were inboard, as can be seen in virtually all modern pickup trucks.
A pickup truck, often simply referred to as a pickup or pick-up, is a light motor vehicle with an open-top, rear cargo area (bed).
In North America, the term pickup is used for light trucks with a lighter duty chassis and factory built, integrated bed, as well as for coupé utility vehicles, often based on a personal car chassis, but also often on a special dedicated chassis for such use.
