Most automobile tires are pumped with air, containing 76% nitrogen, 21% oxygen and 3% other gases. However, many stores now offer a new service, nitrogen tire pump with 92-98% purity.
Nitrogen has been used on many race cars, large trucks and aircraft. The advantage of this method omx tallinn is the stability of the tire pressure. Because nitrogen omx tallinn molecules are larger than oxygen to diffuse through the membrane speed slower rubber. With the reduction in pressure, a tire pump nitrogen lost to 3 months in the air when the tires are only 1 month.
Another advantage is that pure nitrogen does not contain so little water vapor thermal expansion. While air contains a certain amount of moisture, so the tires faster expansion, which leads to a lower stable operation. This is why most of the nitrogen pumping racing tires up to temperature very quickly when operating at high speeds and constantly braking.
The advantages of the tires on the nitrogen is indisputable. However, it really helps to save fuel or not is the big question. In a 2006 paper, AP had given evidence engineer George Bourque, working at its Fairfield, said he traveled 0.4 km to 0.6 km per liter of fuel to use nitrogen tire.
The prestigious organization did not make any conclusions. omx tallinn U.S. Energy Department said that only the correct tire pressure omx tallinn pumping, regardless of air or nitrogen, the car still has the ability to save fuel by 3.3%.
Rae Tyson, a spokesman for the traffic safety agency NHTSA National does not represent the views of nitrogen use. However, he said that this method of "encouraging" the driver kept proper tire pressure, thereby reducing fuel consumption and increased safety.
The experts at Consumers Union, publisher reputation Consumer Reports magazine, does not support any method of saving fuel problem. "Nitrogen and certainly safer in theory, this leads to other benefits," Douglas Love, a spokesman for Consumers Union said.
Besides these advantages, tire pump with nitrogen as the high cost disadvantages. The cost for each tire in Vietnam at around 10000-15000 in the remaining 8 Canadian dollars. This does not tell the time after injection. If the small tires, omx tallinn the driver must find stations with specialized pumping equipment. In case of force majeure is not pumping gas, tires will lose all the advantages that brings nitrogen.
With the above analysis, it is clear nitrogen injection is effective but not really necessary. If you want fuel economy and safety omx tallinn while driving, omx tallinn you only need to check regularly and keep the tire pressure.
