So, how to calculate the fuel consumption of a car?Under normal circumstances, how much energy is needed?Let's take a look!
How to calculate the fuel consumption of the car.
1. Amateur calculation method:
Fuel consumption: 100 75=13.3 liters.
Fuel consumption: 134/130*100=6.1 liter per 100 km, that is, fuel consumption per 100 km is 61 liter.
There is a relatively accurate way to calculate fuel consumption:
Fill up the fuel, return the odometer to zero, refuel again, refill again, and use the mileage on the odometer again, and what you get is fuel consumption.
In this way, you can calculate the fuel consumption of each time more accurately. Fill up the chamber every time you go on in the future, so that you can more easily calculate the fuel consumption.
You can use Excel to design a simple ** for calculation.
For example: the amount of refueling when jumping the gun is 40 liters, the odometer is 500 kilometers, and the fuel consumption is: 40 500 * 100 = 8 liters 100 kilometers.
2. Professional calculation methods:
The basic calculation is fuel consumption per 100 kilometers.
The manufacturer also provides this parameter, which is to divide the actual fuel consumption by the actual mileage covered. That is, fuel consumption per 100 kilometers = (liters) total mileage (km) 100
For example, there is a 1If a 6-liter sedan travels 500 kilometers and consumes 40 liters of fuel, it has: fuel consumption per 100 kilometers = 40 500 100 = 8 liters.
If there is a 2If a 5-liter sedan travels 500 kilometers and consumes 55 liters of fuel, then there is: fuel consumption per 100 kilometers = 55 500 100 = 11 liters.
This is a very simple calculation that many people can calculate.
If you start with the purchase of a vehicle, calculate the cumulative amount of fuel for each purchase, and use this formula to calculate a more accurate fuel consumption per 100 kilometers.
But what if you don't have these raw oil purchase data?
Many people combine the fuel gauge indication with the odometer meter number into the above formula.
This involves a measuring device, if you do not pay attention to the accuracy of the measuring instrument, the calculated result will have a relatively large error.
How to drive more and save fuel.
Fuel saving tip 1: Warm up the car in moderation.
Most car owners have a good habit of warming up their cars in the morning. Just wait for the engine to slow down, or for the water to return to normal. It's a self-defeating one.
In summer, owners can shift gears about 30 seconds after the car starts, and only continue to drive normally after driving for a while in first gear. When driving on the road, never exceed the speed limit until the temperature of the vehicle does not reach a normal level to reduce the wear and tear of the vehicle and reduce fuel consumption.
And in winter, 2 minutes of hot car is enough.
Fuel saving cheats 2: Don't hang D gear while waiting.
If you're waiting for a long time, it's best to turn off the engine. The correct choice is to put on the "n" gear (also known as neutral) while waiting for the traffic light.
The consequence of this is that fuel savings "02%".
Fuel saving cheat three: thoroughly implement vehicle lightweight.
Don't think of the car as your home, many racers will take the internal parts down to avoid unnecessary parts being too heavy. The same applies to everyday cars.
Fuel saving cheats 4: Driving with the window closed can save fuel.
During operation, the air conditioning system consumes some of the engine's power. Some drivers turn off the air conditioner and leave the windows open when driving at high speeds, which can save fuel.
In practice, at speeds of more than 80 km/h, the wind resistance due to air resistance is greater than the fuel consumption when the air conditioner is used.
Fuel saving cheats five: daily maintenance should be paid attention to.
Take good care of the car according to the regulations, change the oil on time, and never use unqualified lubricating oil. Replace the air filter and air cleaner regularly to reduce the suction power of the engine and compressor.
Second, adjust the tire pressure to the most ideal level, and keep the tire pressure at 22-2.5.
As long as one tyre is 40kPa less inflated, the tyre will lose 10,000 kilometers of life, and it will also increase the total fuel consumption of the car by 3%.
If the tire pressure is reduced by 30%, the car's fuel consumption will increase by 5%-10% when the car is driving at a speed of 40 kilometers per hour.
Fuel saving tip 6: Don't rush to speed.
When driving, sudden acceleration and hard braking, it looks cool, but the cost is two or three times what it would normally be.
For an average car, the best "economic speed" should be 60-90 kilometers per hour. Normally, a 4-cylinder car should not travel higher than 100 kilometers per hour when driving on the road. Traveling at a speed of 120 km/h, its fuel consumption will exceed 100 km/h by 20%.
