Formula for calculating fuel consumption（计算油耗公式）

Formula for calculating fuel consumption（计算油耗公式） Formula for calculating fuel consumption(计算油耗公式) Simplified formula for fuel consumption I. Basic formula: Consumption of oil / mileage = fuel consumption per kilometer (usually 100 km fuel consumption as standard caliber, X100) The amount of oil consumed is relatively troublesome. Generally, the full tank is used as the initial data. After running a sufficient distance, the tank is again filled with fuel tank. Mileage data easier to obtain, usually after the tank is full, the odometer cleared, until the next refueling, the data recorded, and once again cleared. (odometer also has errors, the former mechanical form, reversing the table also inverted) Two. Give an example: Walk forward gas station, directly to the tank and odometer cleared, then start your journey into the vehicle; 300 kilometers again into the gas station, fill tankers display 55 liters, envy you! You drive V8 big cuts! Your fuel consumption per kilometer is 0.183333 litres, and 100 km fuel consumption is 18.33 litres! Three, a little more scientific Individual driving habits are different, the road is different, the vehicle load is different, the tire pressure is different, contrary to the wind, the wind is different, the weather is different, the engine condition is different, so.. Even with the same brand and model of the car, fuel consumption will not be the same. And for the same car, a little scientific approach is to calculate the average fuel consumption. For example, a trip, travel 20000 kilometers, you can N times the average refueling results, so that a comprehensive road average fuel consumption. The highest fuel consumption and minimum fuel consumption record, you have to own a car bottom. If there is enough energy and patience, but also the years of each refueling are recorded, including gas station, oil prices, weather, road conditions, whether the use of air conditioning and so on, and then through the EXCEL calculated a comprehensive fuel consumption meter. Four, unscientific refueling and calculation methods Many people are accustomed to adding 1/3 of oil each time, which is known as reducing the load of vehicles. This is not a good idea. The oil pump is in the tank, and it is not a good thing to get enough cooling! Many people used to count the amount of fuel consumption calculation method, I would say, 200 yuan money to run 300 kilometers, who knows how much you add the oil price ah, but also a trouble again! Many people used to go to the gas early in the morning, it is said that the oil temperature at this time is low, the same amount of fuel, the actual gain of a little more fuel, and expansion, cold contraction related. To transfer a post is the knowledge of oil products provided by China gas station network. I saw it was dizziness.. A number of oil storage tank. When the car down to the fuel tank of gasoline tank storing oil when the number of refueling emergency lights (general oil table left a small lattice half, very few cars except), tank car any oil storage number must be maintained to the next gas station. Usually, each automobile manufacturer has different design ideas and different fuel consumption, so the number of oil tank attached to it is different. But you can make sure the car is in full supply. The light is on, and it can turn on 50 kilometers to 100 kilometers or more. For example, corolla car standard is 50 litres of oil tank, oil storage tank is 15 liters, if slowly to flow out, also can add 3 to 4 liters (volume, fuel tank at the gas amount can exceed the standard curve to 53 liters). The tank with 15 litres of oil storage corolla car number can ensure the vehicle refueling emergency lights can run 150 km to 200 km, which is to ensure that people are not particularly careless because you forgot the gas burn because of lack of electronic fuel pump and oil broke down in half, this design can greatly reduce the electronic gasoline because of lack of oil pump and man-made fault broke down rate. Two, fuel consumption calculation and method 1 、 theoretical bench fuel consumption test (the weight of the car is full or full load) Put the engine on the platform, control the environment temperature, the positive fan blow, and the back load with water, simulate the running state of the car, Use computer to control and calculate and draw data and curve charts of power, power, torque, cylinder pressure, intake and exhaust temperature, fuel consumption and so on. This one hundred kilometers and other fuel consumption data and actual data is not the same, is for manufacturers to pick the engine and debug the data used by the car. Some car publicity data is the use of this data; some car publicity data is based on the 2 authoritative fuel consumption test results, and then revised one hundred kilometers and other fuel consumption data given. We usually drive data higher than this, people in the wind, the downhill road, do everything possible to use fuel-efficient methods and the number of accurate fuel metering can be lower than the manufacturer propaganda data. What's more what is the weight of the car fuel economy contest, to minimize (the weight of the car is not loaded), barefoot, what free sliding, empty trunk and so on, there is no time to run what meaning consumption. 2 、 authoritative fuel consumption test In a special experimental yard special on the runway, in terms of humidity, air pressure, tire pressure, in full isokinetic conditions (weighing and filled with heavy trunk); instrument (special flowmeter with scale measuring cup, etc.) cut off the original vehicle oil supply system, instrument a cup of oil run tens or hundred meters (if this is the case, do not calculate acceleration of the fuel consumption, can not slide) to the circuit, in addition to the two calculated 100 km fuel consumption data etc.. 3, more accurate fuel consumption test By special people choose experimental road, in terms of humidity, air pressure, tire pressure, in full isokinetic conditions (weighing and filled with heavy trunk); with a special scale tank to run 100 kilometers (after the loop can be calculated into the acceleration of the fuel consumption, but can not slide in addition, two) to calculate the actual fuel consumption per hundred kilometers of data. 4, more troublesome newspapers, magazines actual driving vehicle fuel consumption test The newspapers and magazines of specialized organizations choose the road of the ordinary, in the same gas station refueling gun with the same and to draw the front and rear wheel parking position, put to the oil slowly just out of time may be in full or full conditions, the basic speed of the 100 km run back the same position of the gas station, refueling gun again put to the oil slowly flowing gas machine just to count out the actual fuel consumption data hundred kilometers (do people, did not increase with the weight of the trunk). The data include fuel consumption per hundred kilometers acceleration, deceleration and small error of oil collection and personal taxi driving technology; everyone is closer to the actual data in the long run economic speed, or something. 5, you can always use the ordinary simple and feasible fuel consumption test We can fix the gas station (choose good, accurate measurement, the old gas station), in the same gas station refueling gun oil to the same or just to jump the gun slowly flowing. The odometer to zero, can run a special trip or 100 kilometers long, can also work is actually used to tank gas mileage, emergency lights, and then to the same gas station refueling gun oil to the same jump the gun or slowly to just how much oil is added to the flow meter. Oil mileage is calculated by adding oil and running kilometers. For example, running 100 kilometers, plus 7.3 liters of oil, 100 kilometers fuel consumption is 7.3 liters (with fuel tank refueling, emergency lights will not light). For example, go to the tank, refueling emergency lights, to the gas station added 36 liters of oil, look at the odometer is 450 kilometers; with 36 liters, by 4.5 in addition to 8, and this 8 is your 100 kilometers fuel consumption. For example, you casually ran 140 kilometers, on the same gas station, added 9.3 liters of oil, with 9.3 liters, by 1.4 in addition to 6.64, and this 6.64 is your 100 kilometers fuel consumption. No matter how you calculate the fuel consumption, you must be the same refueling situation, flow out or jump gun. This is closer to the actual long-distance car running data, suburban common use data, or traffic congestion in the city, unobstructed data. This is of practical significance, but inconsistent with the manufacturer's data, it is more oil consumption, some people less fuel consumption, and your road conditions, distance, driving skills related. 6, you can refer to the simple fuel consumption calculation Fill up the oil until you jump off the gun. Drive to the tank, and when the emergency lights are on, see how many kilometers you've run. With 50 liters minus 15 liters, direct direct calculation of fuel consumption. For example, running 420 kilometers, with 50 liters, minus 15 liters after 35 liters, and then by 4.2 in addition to 8.333, and this 8.333 is your actual comparison of crude fuel consumption of 100 kilometers. Of course, there are other methods, such as long-term record data, calculation, average error and so on.
