Nowadays, the price of refined oil products on the mainland is fluctuating, last year the price of oil once fell to more than 5 pieces, and this year the price of gasoline has risen to more than 7 pieces. When refueling, the owner began to be careful and try to save fuel. Many car owners have found a rule that the front half of the car's oil is always more resistant to burning than the second half of the tank.
After the vehicle is filled with oil, many car owners will record the mileage of the car, some vehicles can run more than 300 kilometers in the first half of the tank, and the second half of the tank of oil can only run 200 kilometers, and the owners themselves can't understand why the second half of the tank of oil is so unsustainable?
First, the shape of the fuel tank is irregular.
The tank of the truck is a rectangular tank, the fuel tank of the private car is irregular in shape, many fuel tanks look like rectangles, in fact, some parts are protruding, and some parts are sunken. The fuel tanks for family cars are designed in a bumpy shape, mainly to target the compact space under the car.
When the car fills the first half of the tank, the volume of the fuel tank is a little more than the second half of the tank. The first half of the tank of oil sounds only half of the total amount of fuel, in fact, the capacity of the first half of the tank of oil may reach about 2/3, so the owner will feel that the first half of the tank of oil is more durable.
Second, the oil amount is calculated differently.
The vehicle calculates the amount of fuel in a special way, with a float inside the tank and this device floating on the surface of the fuel. The connecting rod and slide resistance are connected behind the float, and when the float rises or falls, the connecting rod will also rotate with it, so the owner will find that the fuel consumption changes.
When the fuel tank is filled with oil, the owner begins to use the first half of the tank of oil, at this time the float floating angle is relatively high, the decline is slow, so the owner feels that the first half of the tank oil is more durable. After the fuel is more than halfway through, the buoyancy causes a large sliding distance, and the float descends faster, so the owner will feel unsustainable again.
All in all, because the fuel tank of the family car is not a regular container, the way to calculate the amount of oil is not even, so the owner will feel that the first half of the tank of oil is used longer, and the second half of the tank of oil is not durable.
How to save fuel?
First, develop good driving habits.
Novice driver driving habits are relatively poor, like big feet on the accelerator and brakes, vehicles often sharp brakes will lead to the amount of fuel injection suddenly large and small, long-term driving fuel consumption will definitely rise.
Second, clean up the carbon deposits. Carbon deposits are colloidal substances produced after insufficient combustion of fuel oil, which can be present near the throttle intake tract. More and more carbon deposits, not cleaned up in time, will affect the engine's intake and outlet, and eventually lead to combustion efficiency is affected, fuel consumption rises.
Third, use fuel additives.
Many refueling unions recommend fuel treasure to car owners, although the fuel treasure can not increase the power, but it can clean the carbon deposit to a certain extent, change the fuel quality, and achieve the purpose of reducing fuel consumption.
Fourth, use high-quality fuel.
In order to save money, some car owners often refuel at private gas stations, the oil products of gas stations are not reliable, and some fuels are also added to some additives, which are not resistant to burning at all. The owner of the car is better to spend more money to refuel two barrels of oil, the oil is more reliable, and the fuel is more durable.
Editor's Comments:
After listening to the repairman's explanation, the owner suddenly realized why the first half of the tank of oil was more resistant to burning. Some car owners think that the first half of the tank of oil is more resistant to burning, and every time you refuel, you must fill it up, so as to save fuel. There is no basis for this statement, and adding too much fuel will affect the oil pump.
