计算油耗公式（Calculate the fuel consumption formula）

计算油耗公式（Calculate the fuel consumption formula） 计算油耗公式(Calculate the fuel consumption formula) Simple fuel consumption calculation formula I. basic formula: Consumption of oil/mileage = fuel consumption per kilometer (generally 100 km fuel consumption standard, then X100) The consumption of the oil quantity data to get more trouble, generally used full tank for the initial data, after driving enough distance to fill the tank again, the refuelling data provided by the gas station shall prevail. It's easy to get mileage data, usually when the tank is full, to clear the odometer and keep the data down to zero again until the next time. (the odometer also has errors, which used to be a mechanical watch, and the tables turned upside down.) 2. Examples: Go to the gas station by the long journey, fill up the tank, clear the odometer, and begin your journey. When the vehicle travels 300km, it will re-fill the gas station, fill up the refueling machine show 55 litres, envy you! You're driving a V8! Your mileage per kilometer is 0.183333 litres, and the 100km fuel consumption is 18.33 litres! Third, more scientific The individual driving habits are different, the road is different, the vehicle load is different, the tire pressure is different, the contrary wind is different, the weather is different, the engine state is different, so. Even with brands and models, fuel consumption is not the same. For the same car, a slightly more scientific approach is to calculate the average fuel consumption. For example, a journey of 20,000 kilometers, you can average the results of N refueling, which leads to the average fuel consumption of a comprehensive road. Keep a record of the highest fuel consumption and the lowest fuel consumption, and you have a bottom on your car. If have enough energy and patience, also they will come on each time the conditions were recorded, including petrol stations, oil prices, weather, road conditions, whether the use of air conditioning and so on, and then through the EXCEL calculated a combined form. Iv. Unscientific refueling and calculation methods A lot of people get used to adding 1/3 tank of oil each time, claiming to reduce the load of the vehicle, which is not a good way, the oil pump in the tank, the total lack of adequate cooling, not good! Many people are used to using the amount of calculation to calculate fuel consumption, so say, I 200 yuan oil money ran 300 kilometers, who knows you add oil unit price is how much, still need to calculate again, trouble! Many people are used to the early morning refueling, it is said that the oil temperature is low, the same amount of refueling, the actual fuel is a bit more, with the heat expansion and contraction. Turn a post, it is the oil product knowledge that Chinese gas station network provides. I looked dizzy. The number and reason of oil storage When the car's tank of petrol down to number storage oil tank, oil emergency light is on (general oil with a small half, except very few cars), and any number of attached storage oil tank car can drive to the next gas station must be maintained. Usually each car manufacturer's design idea is different, the fuel consumption of the car is different, its design is attached to the fuel tank oil number is different also. But it can be ensured that the car can be turned on and the lights can be turned on for 50 kilometers to 100 kilometers or more. For example, the standard for a corolla tank is 50 liters, with a fuel tank of 15 litres. If it is added slowly to the outflow, it can add another three to four litres. (it is the volume of the oil in the tank. At this point, the total amount can go up to 53 liters. Corolla 15 litres of number storage oil tank can ensure gas emergency lights after can also run to 150 km to 200 km, this is to ensure that special careless people also won't because forget fuel burned electronic gasoline pumps and broke down because of lack of oil in the half way, the design thought is can greatly reduce the electronic gasoline pumps and break down because of lack of oil failure rate. Calculation and method of oil consumption 1. Theoretical platform fuel consumption test (vehicle weight is full load or full load) Control the engine stand on the platform, the environment temperature, positive fan, followed by water load, simulation of the vehicle driving state, using computer control and calculation and drawing: power, power, torque, cylinder pressure, inlet and exhaust temperature, hundreds of kilometers of fuel consumption data and curve graph. The data of this 100km and other oil consumption is different from the actual data, which is used by the manufacturers to select the engine and test the car. The data on some car propaganda is the data used; The data on some car propaganda are given according to the data of the authoritative fuel consumption test of 2 items and the data of 100 kilometers of fuel consumption. We usually drive is higher than the data, individuals in the wind, hill road, one thousand party hundreds of fuel-efficient way and imprecise refueling metering can be lower than those of the manufacturers literature data. What's more fuel-efficient competition, try to reduce the weight of the car (car weight is not full load), barefoot, neutral taxiing, emptying the trunk, and so on, then run the fuel consumption of what also have no meaning. 2. Authoritative oil consumption test On the specialized track of the special experimental vehicle field, in the specified humidity, air pressure, tire pressure, etc., in the condition of full load of equal speed (weighing the weight of the man and the back box); With special measuring instrument measuring cup (a scale, flow meter, etc.) to cut off the original vehicle fuel supply system, measuring instrument measuring cup inside the oil run dozens or hundreds of metres (seeming is such, do not calculate speed when the fuel consumption, not taxi) after back and forth across the road, in addition to the two calculated data such as hundreds of kilometers of fuel consumption. More accurate oil consumption test The special person chooses the path of the experiment, in the specified humidity, air pressure, tire pressure and so on, in the condition of full load of equal speed (weighing the full man and the back box); After running 100 kilometers back and forth with a special graduated fuel tank (which can calculate the fuel consumption during acceleration, but not taxi), the data of the actual 100 kilometers of fuel consumption calculated in two calculations is calculated. 4. Fuel consumption test of the actual driving vehicles of the troublesome newspapers and magazines Organized by newspapers, magazines, dedicated people choose common experiment road, in the same gas station in the same oil gun and draw the front and parking location on the ground, add oil, slowly to just flow out, may be in full or not full load condition, the basic uniform ran back to the gas station in the same place after 100 kilometers, with the same oil gun when add oil slowly to just flow out again see tankers count out hundreds of kilometers of the actual fuel consumption data (not doing manchu, the trunk also didn't add balances). The 100-kilometer fuel consumption data includes acceleration, A small amount of deceleration and oil recovery and the error of personal driving technology; It's a little bit closer to the actual data that you're going to be running long distances in the economy. 5. Common, simple and feasible fuel consumption tests that can be used regularly You can fix a gas station (choose a good, well-measured, old gas station) and use the same fuel gun at the same petrol station to add the oil to the jump gun or slowly add to the fresh outflow. At this point the odometer to zero, can special trip to visit 100 km or long distance, also can use the mileage is actual work, run to the enclosed tank of gas emergency lights, and then to the same gas station in the same oil gun slowly add oil to jump the gun, or to just how much oil to flow calculation. Calculate the fuel consumption of 100 kilometers with the added oil and the running mileage. For example, running 100km plus 7.3 litres of oil, the 100km fuel consumption is 7.3 litres (with the petrol tank filling the emergency lights will not be on). For example, when you run to the fuel tank, you can add 36 liters of oil to the gas station, and you can see that the odometer is 450 kilometers. So you're going to have 36 liters and you're going to get 8, and that's going to be your 100 kilometers. For example, if you run for 140 kilometers, you add 9.3 liters of oil to the same gas station, and then you get a 9.3 liter, and you get a 6.64, and 6.64 is your 100 kilometer fuel. No matter how you calculate fuel consumption, you have to be the same in the gas, flow out or jump gun. This is closer to the long-distance data on actual car running, the average suburban usage data, or traffic jams and unobstructed data in the city. This is a practical significance, but it is not in accordance with the manufacturer's data. Some people have more fuel consumption and less fuel consumption, which is related to your road conditions, proximity and driving technology. 6. The simple fuel consumption calculation can be referenced After filling up the oil to the automatic jump gun, the car ran to the fuel tank and the emergency lights were just on. After 50 litres or 15 litres, you can calculate the fuel consumption directly. For example, running 420 kilometers, using 50 liters and 15 liters, 35 litres, and then 4.2, to get 8.333, this 8.333 is your actual thicker 100 km fuel consumption. Of course, there are other ways to calculate the average error of the long term data.
