More and more high oil prices, fuel economy is more and more attention, "fuel-efficient secrets" also emerge in endlessly. Although many owners have the consciousness of environmental protection and energy saving, but a little knowledge for fuel-efficient skill, partial to listen to the opinions, so there are many "myth".
　　In recent years, the development of automobile technology by leaps and bounds, the design concept of energy saving are fully applied to the new car. However, in terms of energy conservation and emissions reduction and has not as good as it gets. Whether for environmental concept or cost savings, it is necessary to accumulate some fuel-efficient skills and experience. And understand the oil-saving error is definitely one of the "required courses"
　　In general, is related to the car fuel consumption roughly five factors: displacement, vehicle weight, wind resistance, the matching of engine and wave box, as well as driving habits, etc. First four belong to the "hardware", the last item is the "software". Is said to be "rough", the reason is a lot of problems need to be careful analysis, such as displacement little fuel consumption is a common case, but not absolutely. Because of many problems seem plausible, the "myth" only need special attention. Clear these pitfalls not only may affect the future of driving habits, and even used may change some ideas.
　　Myth: neutral glide save?
　　Slide on the downhill road or slow down, a lot of automatic owner habits slide idling, think this kind of practice is more fuel-efficient, actually otherwise. Idling along not only violate the traffic ban, for using efi engine of the car instead of oil. At present most of the efi engine control system has the function of reduction to reduce oil or oil cut-off this kind of car high-speed belt slide block can rely on its own design, to achieve the effect of fuel-efficient, if in neutral taxiing, this design is less than its rightful role, in fact the car more oil instead.
　　Myth 2: high quality at low speed can fuel economy?
　　Low gears will consume more energy, so the high gears low-speed driving habits behavior seems to be a lot of automatic owners, think that this approach can achieve oil-saving effect. There is no evidence.
　　In any car factory will show the speed of the economy. Skilled owners when shifting in personnel usually feel difficult to detect, seem to be very smooth, it shows that the engine speed and speed is very accurate. These two factors any inaccurate grasp, can cause waste of fuel oil. Specifically, low block a high speed or high gears driving at low speed are fuel-efficient.
　　Myth 3: don't open air conditioning can fuel economy?
　　Vehicle air conditioning requires more energy, but this is not absolute, need to make a concrete analysis.
　　At low speed, fuel efficient than open air conditioning does not open air conditioning. The above mentioned, the factors which related to the fuel consumption, wind resistance coefficient is a condition to consider. Driving to open the window makes the wind resistance coefficient of the vehicle to change. Many cars traveling more than 80 km/hour, when the loss brought by the wind resistance coefficient increases fuel than sealed inside air conditioning to increase fuel consumption.
　　Myth 4: heat can really fuel-efficient car in advance?
　　Habit of a lot of owners in the car after the first hot car for a period of time, that is the way of car, at the same time can also be on the road to achieve the 　　　　　　effect of fuel economy. It is also a myth.
　　Along with the development of the auto industry, to launch new car in technology in recent years has greatly improved, no longer advocating hot car in advance. In fact, this kind of practice fee oil time-consuming, and possible damage to the car directly. A group of related survey data show that in recent years the new push models, part of the engine parts wear problem, about 90% is within 3 minutes after cold start. Visible hot car time shoulds not be too long as well as fuel economy, also is advantageous to the car.
　　Mistake 5: less fuel can fuel economy?
　　Fuel consumption and vehicle weight is correct, but many owners so come on when this factor into account and with as little as possible. This practice right in theory, but it's actually not the case -- reason mainly comes from oil.
　　Although the product label, but at different times of the product quality or have subtle differences. In use process, frequent refueling will lead to product quality, leading to insufficient in the engine combustion, affects both the performance of the car, also increase fuel consumption. Relatively limited load fuel weight, it is not science.
　　Myth: temporary parking stall can fuel?
　　Stalled car doesn't work is sure to fuel economy, but there is another problem: the engine every start of the instantaneous fuel consumption is very big, usually about 20% higher than the normal working state, what province row consumption cannot treat as the same.
　　Some drivers like out car when parking for a short time, may want to consider residence time now. In addition, as the heart of the car engine, many stall, start, certainly will reduce its service life.
　　Myth: manual more fuel-efficient than automatic?
　　Manual than automatic fuel economy seems to be a lot of owner held notion. Now may be a little changed.
　　In the past, the concept of automatic largely confined to the ordinary four QianSu automatic. In automotive technology rapid development today, five-speed automatic, six speed automatic even seven speed automatic city has been equipped with in some new car, the design of the transmission gear ratio and therefore some changes have taken place. Manual than automatic fuel-efficient saying is not a scientific argument.
　　In addition, because of different driving and driving habits, manual models than automatic-shift cars consumption is also likely.
　　Myth: the smaller displacement fuel economy?
　　In general, low-emission vehicles less than large displacement models of fuel, but that is not absolute. Many large displacement models with lightweight body, at the same time also is equipped with advanced engine, etc., the actual fuel consumption is not high is likely to be less than small-engine cars. This is the result of a comprehensive consideration.
　　Myth: power more foot more money?
　　High power and high torque easily reminiscent of high fuel consumption. It has a lot to do with manufacturer for model calibration.
　　Some advanced engine technology, its power output is very smooth, good linear, under the usual speed range can reach the maximum output power and peak torque, fully support the vehicle. In this case the car won't appear the imagined high fuel consumption. On the contrary, a small cart situation may be good to see, caused by a lack of power, fuel consumption has soared.
　　Myth: fuel-efficient products really work?
　　At present, the domestic has not the exact standard to judge oil-saving effect of fuel-efficient products, still had better take caution in this area.
　　Many car manufacturers in the process of engine development, vehicle research and development, attention has been paid to the problem of fuel-efficient, many models factory have demonstrated the reasonable oil-saving device, protects adapted easily to "steal meters and costly". Now on the market of fuel-efficient product variety, different principle. Best for this kind of product or taking a cautious attitude, don't superstitious propaganda effect. According to the survey, because with a "oil-saving device" and cause damage to the car's case is not rare, but oil-saving effect is not obvious.
