In the hot summer, probably because of the large amount of air conditioning use reason, many car owners began to complain of lack of motivation. "The original out of the parking Xiao-Po, 2 block can secure in the past, but now they must be reduced to a stop." "The car is always filled with people just like similar increase is not on speed, began to suspect that the problem is gasoline , but later found a gas station is the same for! "In fact, every summer, grumbling about the vehicle underpowered up more, the reason is that the air conditioning. Do not underestimate the automotive air conditioning compressor horsepower horses occupied when working on large displacement cars is probably nothing, but for small-displacement cars, the drivers will obviously feel the car is heavier, the slope do not, and high-speed hard for. Although the beginning of autumn, but the heat of the South did not end so quickly, how to make your car when the use of air conditioning can also be motivated, it worth our study.
First troubleshooting
First we have to determine is that the air conditioning rather than anything else problems slowing down your car. In fact there are numerous possible failure will cause the vehicle dynamic performance degradation. Especially in the hot summer months, air conditioning hidden behind these failures, often not found. Such as thermostat or clutch failure, the majority also occur at high temperature under, so it is easy to be the driver of the miscarriage of justice. In fact, what is the air conditioning or other failure caused by power down, it is not difficult to determine. You only need to turn off the car was driving strenuous conditioning, if marked improvement in power at this time, it is the air conditioning problem. And even if the air conditioning turned off the vehicle but still weak, then you may need to repair the vehicle plant more in-depth checks.
To choose the right oil
Hot summer, lubricant viscosity increases as the temperature decreased by heat, likely to cause excessive consumption, if you use an inappropriate oil and falling into disrepair, it may cause fatal damage to the engine. Only choose the regular manufacturers, comply with the relevant standards, the technical supervision department inspection of the product is the right choice, but the oil level model, it is necessary to strictly refer to require manufacturers choose.
It is noteworthy that the engine is operating at high speed, metal parts expansion coefficient increases, the working gap between the parts is reduced, will increase the wear, while the top of the piston, the combustion chamber cylinder wall and the valve carbon on a component class the metal parts colloidal attachments poor thermal conductivity, speed mechanical damage. If too thin oil under high temperature lubricant film is not easy to form, the same accelerated engine wear and therefore should always check the oil dipstick, where there is the problem of insufficient amount of oil required to replenish. In addition, you should consider using a more expensive but the results are excellent multigrade synthetic oil, because these oils contain anti-high temperature and anti-oxidants, and to adapt to a variety of temperature of the product characteristics, it has become heated and thickens when cooled thinning The self-regulatory functions.
As a car owner, you need to understand the lubricant viscosity mark. The current level of oil packaging mostly use SAE logo. For example: SAE15W-40, SAE5W-40. "W" after the number indicates an index of lubricating oil temperature, the greater the value of the protection of oil at high temperature the better the performance.
Upgrade spark plug
In automobile hub unit Hengding see replace the spark plug is an important means to enhance vehicle dynamics. High-performance spark plugs can withstand greater heat and mechanical loads, and can adapt to a higher ignition voltage, the ignition energy is plentiful. Iridium alloy electrode materials such as spark plugs, can withstand extremely high temperatures without being meltdown, and the electrode wear are strong, so that longer life. A strong ignition energy is able to enhance the efficiency of fuel combustion in the engine, without increasing the fuel consumption under the premise of effectively strengthen the engine power output.
Similarly, an increase in high-voltage coil voltage high-voltage ignition or to replace the ordinary high-energy high-voltage ignition, also can improve the ignition efficiency thereby enhancing power, but unlike the replacement of spark plugs, which already belongs to retrofit areas, and we are here to not elaborate.
Fuel not lightly
According Hengding automobile hub unit is understood that more than 80% of the owners should use more than 93 gasoline, in which 80% of the owners of them, nearly 60% of the candidates are wrong grade of gasoline, including lower standard and excessive oil. Experts pointed out that the short term impact of excessive oil on the car is not obvious, but long-term use will shorten the life of the car. To save money long-term oil will be marked down to bring greater damage on the car, this hazard at temperatures above 30 degrees Celsius was particularly evident in the exposure, so the summer with particular attention to the proper use of gasoline.
What kind of grade gasoline generally determined by the engine compression ratio, usually manufacturers will be marked in the manual compression ratio and gasoline label matches, the owner of the best according to label oil. Long-term use of low-grade gasoline will cause abnormal combustion, causing detonation, fuel consumption, and driving weakness knock phenomenon. Especially in the summer, the outside temperature is high, easy to distribute the heat, the evaporation temperature of the oil is high, and therefore more easily generated in the engine coke, or the formation of air resistance blocked pipeline, severe may also stop the engine.
Ensure the correct fuel grade, while the choice of the gas station is equally important. Especially in the environmental field are not familiar, it should adhere to the large chain of gas stations, uneven quality of the small gas stations often charge high to low standard oil standard oil situation, once used, not only the power will fall significantly, the engine will damage.
Car also weight loss
Where owners complain that summer open air, immediately feel the car seems more like a person sitting, but in fact you are sitting in a car might really perennial invisible passengers too! This is not a ghost story, you think, ah, vehicle weight, the greater the more expensive oil weakness, which is why most large displacement SUV run, but the fuel consumption of a small displacement of the car but much larger cause. Everyone understands this truth, but often overlooked in the usual car Shique. In order to facilitate such a moment, in the car placed a box full of mineral water. Or neglect to organize, trunk in shoes, oil bristle. Do not underestimate the weight together is likely to have tens of kilograms, that is equivalent to more than one passenger ride!
Hengding automobile hub unit recommendations, in order to try to give the vehicle weight reduction, advocating every refueling only add 1/3 boxes. We do not need less extreme, but do not often use the stuff out of the trunk, so you may be able to produce fuel oh surprise. And if for a long time in the urban area, with the words, in fact, even the spare tire can be removed, and that they help you save a preschooler's weight, the car dynamic natural light.
Always check tire pressure
Tyre is the car's foot, if the foot is a problem, how the car run faster, run province. In real life, too high or too low tire pressure will increase the car's fuel consumption, but will also affect tire life and safety of the vehicle. Tested to comply with the requirements of tire pressure can reduce fuel consumption by 3.3%. If the tire pressure is 30% lower than the standard value, when the car to 40 km / hour speed driving, the car fuel consumption will increase by 5% -10%! The low tire pressure, will greatly increase the tire's rolling resistance, severely reducing vehicle power performance. In addition to fuel and fatigue, the tire shortage will increase the risk of a puncture, especially in the hot summer months, owners have to be careful. Owners should develop a ring on the front of the car tire car one week observing the habit, the best vehicle equipped with a tire pressure gauge, periodically check the car's tire pressure, tire pressure checked once two weeks is the minimum standard.
In addition there are many owners, in order to vehicle's appearance and driving stability, higher upgrade for the car tire sizes. Widening the width of the tire, is to enhance the natural grip and stability of the vehicle, but the side effects is to enhance the rolling resistance of the wheel, fuel consumption and tire noise is not only increased, and the dynamic performance of the vehicle should be discounted. So in the stability and dynamics between the owners had better weigh clear.

Engine to carbon
Little opportunity for city driving a vehicle ran out of speed, coupled with fuel quality is not high, driving tens of thousands of kilometers of the car, it's easy to appear, we often say coke. Coke site may appear in the inlet, may appear in the nozzle may also appear in the throttle, but both appear where will inevitably reduce engine power output, but also affect the performance of the vehicle's fuel consumption. If the car has a serious shake when idling, acceleration weakness or ignition difficult problems, we suspect vehicle in relation to a serious coke formation. At this point, we need to repair the engine and oil plant a thorough cleaning.
But in addition to carbon is not finished once and for all, experts recommend owners should develop good driving habits, long-term high gear at low speed or idle waiting for a long time, are likely to cause the vehicle coke. Driving the right way is to let the engine speed is maintained at a more reasonable range, not only difficult to produce coke, are more likely to play out the way it should have the vehicle dynamic performance. If possible, it should also be periodically fuel detergent used to prevent the formation of carbon long.
Moderately with air conditioning
Finally, we look back and say, said air conditioning. Yes, the air conditioning in the summer affect vehicle dynamic performance is the biggest factor, but in addition to hot days this objective reasons, some motorists abuse conditioning habits can not be ignored, do not only affect the power, it will affect the health of persons on board . So, how to ensure the comfort of the premise, intelligent and rational use of air conditioning, the owners are the learn. Rational use of air conditioning in summer, is the key to reducing vehicle fuel consumption. Experts on how to use energy-saving air-conditioning to make a few: in the sun exposure of the vehicle, the car should not be immediately open air. Reasonable approach is to open the windows (also opened the door), and without the open air, under the premise of the tone set higher fan gear, car driving away the heat, and other vehicles moderate cooling, then open air.
In addition to properly open air outside, while driving, the fan speed should be reduced. Air temperature setting should not be too low, generally 25 degrees Celsius more appropriate. For non-automatic thermostat manually adjustable air-conditioning, the proposed closure of the co-pilot aboard the unmanned air, let cool air in the cab, so that can effectively conserve fuel consumption.
In addition to the rational use of air conditioning, because the relative lack of low-emission vehicles powered, open air the engine needs more energy. Power shortage, will lead to a deeper driver depresses the accelerator, which improves fuel consumption from the other side. So small displacement models in the open air, either the temperature or wind speed settings, should do what
