International Truck MPG - Why US Domestic Ratings Differ Autos Articles | July 10 Joe Pavelski USA Jersey , 2008
Differences between domestic US trucks and international trucks and the reasons these differing standards causes a change in the fuel economy.
There are many differences between domestic US trucks and international trucks. One of them is that international truck mpg (miles per gallon) figures are rated much higher than their US counterparts for the same class and type of truck. This specific difference is due to many reasons.
These reasons are caused by many differences. One of them is that domestic trucks plying in the US are made by US-based automobile manufacturers. These manufacturers follow SAE (society of automotive engineers) standards, whereas trucks made in Europe follow European standards and trucks made in China and Japan follow their own standards.
Differences in different standards cause a change in the fuel economy of vehicles manufactured in the US and those manufactured elsewhere. Part of the difference is due to different criteria specified in these different standards. However, the common aspect about the different non-US standards is that most of the criteria result in manufacture of similar class of trucks having almost similar mpg characteristics.
US manufactured trucks generally lag behind slightly in actual mpg of comparable models of trucks. Part of this is also due to the influence of the big three of the US automobile industry namely GM Jamie Langenbrunner USA Jersey , Ford, and Chrysler on the US federal government.
These companies have invested far too much in their sheet metal based plants to make drastic changes in the process and materials of manufacturing. This is why their truck models are heavier. Therefore, they have a lower fuel economy than most European and Japanese truck models. Japanese models especially have incorporated more material-related and other technological innovations to reduce truck weight and fuel economy.
Part of the reason US trucks are heavier lies in the fact that they are equipped with more powerful engines. More powerful engines guzzle more fuel and result in lower fuel economy. Even these US manufacturers cannot be blamed because US consumers of trucks have had a traditional and specific penchant for powerful vehicles. However James van Riemsdyk USA Jersey , with gasoline prices climbing beyond the $4 per gallon mark, this is set for a change as fuel economy is having a greater impact in the US market than it had earlier.
The US EPA (Environmental Protection Agency) has also tried to correct the course to actualize truck mpg ratings by dumbing down its earlier published ratings to bring them in sync with practically achievable figures.
It rates the mpg of various current trucks and cars plying in the US on an annual basis. It classifies different vehicles under different classes. Even custom configurations of hybrids and other trucks are rated by the EPA.
The traditional outlook of people in the US towards truck fuel economy is also one reason for the difference. Moreover, people in the US have traditionally had far more money to worry about high truck speed and its consequent adverse impact on fuel economy. International truck mpg figures are more realistic and better. This is because of the awareness of the impact of crude oil price rise and operation of trucks at lower optimum speeds to achieve higher fuel economy.

The United Nations Economic Commission for Europe concluded in its 2003 Robotics Survey that robots are among the worlds most in demand commodities. Sectors demanding robots include industrial plants, science and technology Erik Johnson USA Jersey , research, medicine and household work. Growth rates for sales in 2003 reached 35% in North America, 25% in Europe and 18% in Asia.
Robots in the manufacturing industry have been equated as the number of robots per 10 Dustin Byfuglien USA Jersey ,000 workers. In the motor manufacturing, it can be predicted to have 1 robot as replacement for 10 workers. This brings us to the level of competency and accuracy in terms of jobs done by robots and by human workers.
Robots have been employed in application from food to automobiles. Japan has been the leading country in utilizing robots, however in 2003 the United States spent $877 million in buying robots for material handling in factories. The automotive industry has used C flexrobots for odd and dangerous jobs before but now even the simplest tasks such as installation and welding are being automated.
Industry sectors employing robots
In food manufacturing and assembly Derek Stepan USA Jersey , Adept Robots, can make 75 to 125 Oreo cookies a minutes. For the service industry, Automated Teller Machines (ATMs) have taken over the role of a cashier in banks. In restaurants David Backes USA Jersey , the self service check out machine is beginning to be a familiar sight.
In the health service sector, experiments on robotic companion to assist the elderly in home for the aged and in hospitals are under way. They are equipped with a real time video feed that is transmitted among the nurses, patients and physicians.
