Open air car fuel consumption impact of big, after reading thIs article you Will know

In most of the country, especially in New York, where the author of the summer driving on the road no air conditioning to believe that few people can stand. Despite the open windows, but also a window Unit blowing in hot air, but also such various exhaust. The open air a lot of people are worried fuel consumption, because in many people’s consciousness, Automotive air conditioning with home air conditioning Is power, just as much fuel consumption. But that really the case? The impact of air conditioning on fuel consumption, how much? ThIs Issue Is to us the truth Xia it.

on the type of test vehicle air conditioning, pre-test first to introduce the category of the Car air conditioner, Car air-conditioning Is currently divided into fixed and variable row row air conditioning air conditioning are two types, usually said manual air conditioning are fixed row air conditioning, Automatic air conditioning has given row have changed row. Fixed row air conditioning means that whatever you adjust the temperature Is high or low, the compressor output air temperature Will not change varies. Variable compressor dIscharge air conditioning means output power variations with temperature changes of the air conditioner. The lower the temperature, the greater the power output of the compressor; the higher the temperature, the smaller the output power of the compressor.

What test and how to test? Fuel consumption for air conditioning problems we feared, the truth of Man Will be measured. Including testing air conditioning and fuel consumption differences are not open air conditioning, fuel consumption differences at different temperatures and different wind situation after the air conditioning. By comparing different fuel consumption of air conditioning conditions, see the impact of air conditioning on how much fuel consumption. The test model uses a New York Automobile MitsubIshi Jin Hyun ASX 2013 paragraph 2.0 Automatic four-wheel drive flagship version, equipped with variable row air conditioning, we Will adopt the constant speed test, select the Outer Ring Road in University City, where fewer people drive less , traffic conditions at different times every day basically no difference, can be maintained at a relatively constant speed, so the impact of environmental factors in the testing process can be minimized.

Hyun Jin MitsubIshi unique 4B11 MIVEC engine with continuously variable valve timing and lift system, the overall power transfer bias output high, at 6000 rpm burst maximum power may be 123 kilowatts (166 hp), the maximum torque of 197 Nm Is generated at 4200 rpm. While using a CVT gearbox, Jin Hyun power output Is very smooth and soft, silk Xu lack of passion. Since Jin Hyun test used with electronically controlled four-wheel drive system, thIs test in order to pursue a more realIstic effect, only select 2WD precursor mode for testing. University Car outer circle of about 17 km, air conditioning in each condition to run three laps, running at the speed maximum speed limit of the road. Each time by driving with a driver. After the gas station outside the ring as a starting point and end point, before the test fuel at the gas station to fill, finIsh 3 laps back end again fill the tank, the fuel consumption Is calculated in accordance with the conditions of different air conditioning running dIstance and the amount of fuel value, in order to make comparIson.

comparing the test results, the testing process, we travel at the highest speed possible under actual road conditions, in addition to the traffic light, the remaining traffic can basically at 70-80km / h the speed of travel, the final six different working conditions of air-conditioning the average speed was about 53km / h, the mileage each time are all stable at 50.3km. Fixed at the same gas station to refuel with the same gun, jump every time when refueling only once the gun, the final actual test results 🙁 new hot spot shown in the following table Automobiles, Automobile tips on daily continuously updated knowledge of the Car, like Please pay attention to the article, there are suggestions please leave a message, I remember reading the thumbs forward yo!)

from the above measured data, there were two surprIse unexpected results. We can see that in both cases the opening 27 ℃ and 23 ℃ breeze volume, measured as high as 8.3L hundred kilometers above, thIs result we have conducted two tests, the test results can be twice more than eight.3L, it Is very puzzling. Given that both are so abnormal results, the next we Will have the opportunity to get another test Car to be measured, then look at the results. Despite these abnormal data, we look at other data, can be seen without air conditioning, and measured one hundred kilometers fuel consumption of only 5.66L, and when the open air temperature to the lowest temperature, fuel consumption Will rIse 6.54L , whole difference 1L; and then, as the air volume increases, the corresponding increase in fuel consumption. At the same lowest temperature, stage 2 and stage 4 the wind wind fuel consumption difference Is small, only 0.04L, stage 6 but four air volume air volume and fuel consumption are different, the difference of nearly 0.4L.

Is commendable, Jin-hyun except no air conditioning and air conditioning with fuel consumption difference 1L / 100km outside, not in the power output and feel the obvious differences, there Is still preach with accelerated push back remain so. Unfortunately, little Is prone to slipping CVT gearbox. Note that, due to the relatively good road conditions during testing, to higher speed constant speed, so the test out of the fuel consumption value Is also relatively low; but we are the focus of thIs test Is to affect the air conditioning on fuel consumption, the key It Is to ensure that each round of testing as much as possible the conditions are quite similar.

summary: from New York Automobile MitsubIshi Jin Hyun measured results of thIs point of view, the impact of air conditioning on fuel consumption Is very obvious, one hundred kilometers fuel consumption difference of nearly 1L, relatively speaking, the effects of different amounts of air Will have to be smaller, but also reached the maximum 0.4L, and differences at different temperatures constant air volume, thIs Is clearly abnormal test results do not rule out a test drive the impact of the Car, the next opportunity we Will be tested once again alone, please look forward to. Jin Hyun no air conditioning on average only 0.32 yuan / km, air conditioning, compared to the coldest 0.40 yuan / km, even in urban traffic at most 0.60 yuan / km, in fact, Is not very cost oil. No air conditioning in summer drove per hundred kilometers save the few dollars, Will only bring a Rehan and breathing other people’s waste gas. As not open, apparently own the hearts of everyone answers.
