car owners know that they fill a tank of oil could probably run many kilometers, but sometimes they found a box of the same oil not run so far has no oil, inexplicable increase in fuel consumption, a lot of these owners a situation attributed to the aging of the car, while ignoring the fuel in the car to keep a car in the details produced increases. Grilled today to several reasons inexplicable increase in fuel consumption of a steak with you. Cause
First, the car raising aspects:
1, tire pressure. We all know that the car is on the tires and ground friction ahead, tire pressure within a normal range when the car and the tire itself had no effect, but when the tire pressure is too high or too low on the car and tires They are unfavorable. Tire pressure is too high will make the tire pressure is too high friction tires, loss of adhesion, affect the braking effect, but also affect tire life; rolling resistance of the tire will cause performance degradation, likely to cause puncture; except accelerate tire tread pattern center of local wear, the decline in tire life, body vibration increases, indirectly affect the life of the other parts of this that when we should pay attention to tire inflation. Another case is the tire pressure is too low, which is a big reason for the increase in fuel consumption.
When the tire pressure is too low, the steering wheel becomes heavy, easy deviation, while also causing damage to the bead portion and abnormal wear, the tire strength decreases; the largest factor is the tire friction with the ground multiplied, will cause a sharp increase in tire temperature, tire soften sharp decline in strength, high-speed driving, can lead to a puncture. But now most of the vehicles are equipped with tire pressure monitoring devices, cars are not equipped with this feature we should note, is necessary and timely check tire pressure when the steering wheel becomes heavy and so in some cases appear to prevent the tire pressure is too low to bring harm.
2, spark plugs, intake and exhaust soot. Since some oil or driving habits lead to the cylinder surface such as ignition and deflagration abnormal combustion, which increases the spark plugs, intake and exhaust valves of coke, carbon or the aging will cause the spark plug ignition energy and an ignition stability decreased, resulting in increased fuel consumption. Intake may result in insufficient coke intake air amount, the volumetric efficiency decreases, so that incomplete combustion will increase fuel consumption, exhaust gas will cause the exhaust valve is insufficient coke, residual gas in the cylinder increasesAnd more indirect effects of the intake process. Will appear in the general car went from 20,000 to 30,000 kilometers this case, so we keep a car at this time we should be careful to check whether this phenomenon exists, if there is going to clean it.
3, ldquo; three filter rdquo; replacement. three filters, that is, air filters, oil filters, fuel filter. This three is the need for regular replacement, if not a long time to be replaced, they get dirty, decreased filtration capacity, incomplete combustion of fuel, fuel consumption will naturally increase, so the replacement time car owners still have to pay attention to what the.
4, misalignment of the various sensors. In general this rarely happens, but it also should be noted that, if the tire pressure checked, coke these common problems still not solve the problem we must consider this aspect to the. The oxygen sensor is misaligned fuel air mixture ratio become inaccurate, resulting in incomplete combustion. Once the water temperature sensor misalignment or problems with electronic fan circuits, electronic fan will operate uninterrupted fall in temperature cause the engine output will decrease resulting in increased fuel consumption.
5, the cylinder pressure is insufficient. Since the cylinder is generally poor air tightness, this usually occurs with 23 million kilometers of vehicle, will lead to lower energy conversion efficiency of the engine, leading to increased fuel consumption.
Second, the car aspects of reasons:
6, fueling violent while driving. personal driving skills affect fuel consumption is still very large, many people see in the movies before starting Bigfoot H-throttle is very cool, and it will treat the car, in fact, this is very undesirable, after all, not a stop line track start line, this will cause incomplete combustion of fuel, resulting in increased fuel consumption. Each will have its own fuel economy speed range, usually around 80km / h, if prolonged high speed driving on high speed will increase fuel consumption.
7, frequent braking. this case Needless to say, frequent braking will dissipate the kinetic energy of the car itself, then frequentStart to accelerate, this stage is large when the engine load, fuel consumption also becomes higher, the higher the initial acceleration becomes longer fuel consumption, so to slow down in advance in the daily use of the car, do not brake frequently, it will also increase fuel consumption .
8, heat and air-conditioning the vehicle. will be very cold in the northern winter when the car will become very cold, so generally there will be a hot car of course, if the distance from home to work is short, then the car just heat it to the destination, and then back then, when hot cars, hot car twice will consume a lot of fuel, then there will be a significant increase in fuel consumption if coupled with air conditioning. Now the summer, into the car air conditioning can also lead to increased fuel consumption have some.
said so much, nothing more than allow the majority of riders to pay more attention to the daily car car car support, attention to every detail, so make your car more durable longer life, do not waste time repairs have more time to enjoy the good life.
