Trucks

Trucks: - A truck is a type of motor vehicle that are commonly used for carrying goods and materials. Some light trucks are relatively small, similar in size to a passenger automobile. Commercial transportation or fire trucks can be quite large and can also serve as a platform for specialized equipment.
International variance
In the United States "truck" is usually reserved for commercial vehicles larger than normal cars, and for pickups and other vehicles having an open load bed.
In the United Kingdom and the Republic of Ireland, lorry is used as well as "truck", but only used for the medium and heavy types (see below); i.e. a van, a pickup or an off-road four-wheel drive vehicle such as a Jeep would never be regarded as a lorry in these countries, unlike in the United States. The same applies to the initials "HGV" (for Heavy Goods Vehicle) which is basically synonymous with "lorry". The word truck is also accepted in these countries, and can apply to large vans as well as to lorries (i.e. its scope is slightly wider).
The word "lorry" is also used in Cambodia, although here it can refer to a train.[1]
In Australia and New Zealand, a pickup truck (a relatively small, usually car- or van-derived vehicle, with an open back body) is called a ute (short for "utility") and the word "truck" is reserved for larger vehicles.
Other languages have loanwords based on these terms, such as the Malay language and the Spanish language in northern Mexico.
A commonly understood term for truck across many European countries is camion. Additionally, from the German language the initials "PKW" (PersonenKraftWagen or passenger carrying vehicle) for a car/van or small truck) and "LKW" (LastKraftWagen or cargo/load/freight carrying vehicle) for larger trucks are understood.
In U.S. English the word "truck" is used in the names of particular types of truck, such as a "fire truck" or "tanker truck". Note that in British English these would be a "fire engine" and "tanker" respectively.
Engine: - The oldest truck was built in 1896 by Gottlieb Daimler.[5] Small trucks such as SUVs or pickups, and even light medium-duty trucks in North America and Russia will use gasoline engines. Most heavier trucks use four stroke turbo intercooler diesel engines. Huge off-highway trucks use locomotive-type engines such as a V12 Detroit Diesel two stroke engine.
North American manufactured highway trucks almost always use an engine built by a third party, such as CAT, Cummins, or Detroit Diesel. The only exceptions to this are Volvo and its subsidiary Mack Trucks, which are available with their own engines. Freightliner Trucks, Sterling Trucks and Western Star, subsidiaries of Daimler AG, are available with Mercedes-Benz and Detroit Diesel engines. Trucks and buses built by Navistar International usually also contain International engines. The Swedish manufacturer Scania claims they stay away from the U.S. market because of this third party tradition.
In the European Union all new truck engines must comply with Euro 5 regulations.
