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 Cheap Joe Panik Jersey , 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 Cheap Evan Longoria Jersey , 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.

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 Cheap Willie Mays Jersey , 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， July 14 (Xinhua) -- Chinese online travel agency Tuniu is taking on rivals Ctrip and Qunar for a bigger share of the country's online tourism market by expanding its services to flight and hotel bookings.


Over the past ten years， Nanjing-based Tuniu has focused on providing leisure travel services， which include helping travelers book tickets to tourist sites， local transportation， package tours and itineraries at destinations both in China and abroad.


Online travel agencies like Tuniu have boomed with the growth of China's middle class. According to research firm Analysys， Tuniu was ranked as the second largest online leisure service provider in 2015. The company had a market share of 23.1 percent， slightly lower than the 24.6 percent held by Ctrip， according to Analysys.


Having closed the gap with Ctrip in leisure travel， Tuniu has become more outspoken about its ambitions to enter the airfare and hotel booking business， which have earned rivals Ctrip and Qunar their dominance in the market today.


Tuniu co-founder Donald Yu said at a press conference this week that its expansion into flight and hotel reservations will help better serve customers who have booked other travel services through Tuniu.


Tuniu's inroads into services dominated by bigger rivals also come as China's biggest airlines try to sell more tickets directly， rather than paying a commission fee for sales through web services.


Last year， China's state assets regulator mandated that the country's three state-owned airlines raise their share of direct ticket sales to 50 percent in the next three years， compared with less than 30 percent currently. The regulator also ordered commission fees paid to agencies to be halved from 2014 levels. These changes are set to hurt online travel service providers that have relied on plane tickets as a significant source of revenue.


Earlier this year， the country's largest airlines stopped selling tickets via Qunar's online booking platform， citing complaints from customers over issues such as imposing additional costs for flight cancellation and rescheduling， penalties and pricing.


Qunar's sparring with major airlines has affected its ticketing business and bit into revenues. Flights and related revenues at Qunar slid 12 percent to 86.57 million U.S. dollars during the first quarter this year from the fourth last year.


Airfares now account for the largest share of China's online travel service market， at 58.3 percent last year. Hotel booking came in second at 20.8 percent， according to data compiled by consultancy iResearch.


However， the share held by flights has declined steadily over the years as leisure travel services emerge as a promising business for online travel agencies. Leisure travel services are expected to account for 18.7 percent of the market this year， up from 16.2 percent in 2015， iResearch said.


Yu said tickets sales through online travel agencies still appeal to customers， despite a.
