The word ?truck? is believed to be a derivative of Greek word ? ?trochos? which takes the meaning of a wheel. Lorry is yet another term used in this conjunction in United Kingdom whereas wagons with large wheels are known as trucks in North America. Pickup trucks Logan Couture Jersey Sale , semi trucks, GMC trucks are the variants that are available. In countries like New Zealand and Australia a small vehicle with open back is known as ?ute? (abbreviated form of ?utility vehicle?) or also known as pick-up. In the US only large vehicles used in commercial purposes are called as trucks.

The various important parts of the truck are the Engine, the Drive train and the frame.

Engine: An Engine forms the most important part of a truck as it decides the running capability of a truck and has to be carefully chosen to match the application for which the truck is intended to be used. Gasoline engines are generally used by small trucks like the pickups or SUVs (Sport Utility Vehicles) and also by the medium-duty trucks. However heavier trucks generally use four stroke turbo intercooler diesel engines and highway trucks employ locomotive-type engines which are either two-stroke or a V12 Detroit diesel engine. Most of the truck manufacturers in North America outsource the engine, whereas companies like Volvo and Mack Trucks use their own engines. Euro 5 regulations are complied with by all the truck engines in European nations in the interest of the environment.

Drive Train: Light duty trucks use transmission method similar to that of the cars which are either automatic or manual with synchornisers. Heavier trucks however use manual transmission without synchroniser that is less bulky. Crash boxes (transmissions without synchronizers) have a requirement of employing double clutching for every shift, called as ?floating?. Generally North American setups include 9,10,13,15 and 18 speed levels. Semi-automatic or fully automatic transmission system is generally preferred to reduce the fuel consumption. In European market the gears may be of 8, 10 and 12 in case of manual transmission while for automatic transmission it might range anywhere between 5-12 gears. The trucks generally have range shift pattern in the gear system.

Frame: Two parallel boxed rails held together by cross members are the main composites of the frame of a truck. They may also be called as ladder frames since they resemble that of a ladder when tipped on end. Crossmembers are mostly attached to frame rails by using rivets or bolts, but sometimes may be welded in case of heavy duty application. The material used to make frame is generally steel but aluminium can also be a substitute to it.

Although trucks contribute to some pollution, they eject fewer air polluting emissions when compared to a car or any other vehicle, but still it contributes to a high level of sound pollution.

BEIJING, April 27 (Xinhua) -- Chinese industrial businesses reported improving profitability in March, propelling profits for the whole first quarter onto a faster track.


Profits of industrial companies with annual business revenue of more than 20 million yuan (3.25 million U.S. dollars) reached 1.3 trillion yuan from January to March, the National Bureau of Statistics (NBS) said in a statement on Sunday.


Their profits rose by 10.1 percent in the first quarter, compared with a 9.4-percent increase recorded in the first two months.


The acceleration was fueled by an improving performance of firms in March, when they raked in 513.2 billion yuan in profits, up 10.7 percent year on year.


The NBS attributed the improvement last month to the rebounded profitability in the telecommunication sector, whose profits surged by 63.4 percent from a 14.1-percent decline in the first two months.


The weak base due to sluggish performance of industrial enterprises in March 2013 was another major contributor to the improvement, according to the NBS.


In the first quarter, profits of private firms rose the fastest at 14.2 percent to reach 419.1 billion yuan.


State-owned and state-holding industrial enterprises achieved total profits of 354.8 billion yuan, up 2.9 percent year on year.


Combined profits of foreign-funded enterprises and companies funded from Hong Kong, Macao and Taiwan stood at 301.1 billion yuan in the first quarter, up 12.5 percent from the same period last year.


Joint-stock enterprises attained total profits of 755 billion yuan, posting an increase of 9.1 percent year on year.


By sector, industrial enterprises in the mining industry achieved profits of 168.5 billion yuan in the first three months, tumbling by 15.1 percent.


Companies in the manufacturing sector enjoyed a 13.9-percent rise to stand at one trillion yuan in the period.


Notably, the majority of industrial profits in the first quarter were made in just a few sectors, such as auto manufacturing, power and heat generation, electrical machinery production and telecommunication equipment production.


Producers of coal, ferrous and non-ferrous metals, oil and natural gas, reported steep profit declines in the first quarter due to falling prices resulting from sluggish demand, said the NBS.
