How does the 2010 Besturn B70 fuel cap work?

What negative pressure, what is gasoline? Volatile hydrocarbons, boiling point range of 30-205 degrees, the violent shaking of the body while driving, the work of the gasoline pump will accelerate the volatilization of gasoline, and the vapor pressure in the fuel tank will be generated (greater than the outside atmospheric pressure).

The fuel cap should be a single valve that can only take air into the tank and not out of the tank cap, and there are two reasons for doing so:1Prevent gasoline from leaking from the tank port after the vehicle overturns.

2。Ensure that no vacuum is formed in the fuel tank, avoid the deformation of the fuel tank due to the vacuum and cause the gasoline pump to break, the gasoline vapor in the fuel tank is adsorbed by the carbon canister to adsorb the gasoline molecules, and the separated air is then discharged into the atmosphere to avoid pollution; When the water temperature of the engine reaches about 75 degrees, the engine computer controls the solenoid valve of the carbon canister to be conducted, and fresh air is sucked in from the air pipe mouth of the carbon canister, and the gasoline molecules originally adsorbed on the activated carbon are brought into the intake manifold and then into the cylinder to burn out. This situation usually occurs after the gas tank is often filled, and waits until the gasoline in the gas tank is almost used up or there is 1|| left3 or 1|It only appears at 4 o'clock, and only refuels each time.

First, two hundred yuan car, even if the fuel tank cap is damaged, it will not damage the oil pump, because the oil is less, the air in the fuel tank is more, and before the vacuum is formed, the fuel tank cover will be opened to refuel, and the fuel tank cover will be opened and the air will enter, so circulating, the atmospheric pressure is very large, and the gasoline pump can be easily folded in two sections.

Summary. Hello dear, <>

I am glad to answer for you, the oil in the Besturn 09 B70 tank can be pumped out by the special pumping device of the fuel tank, the siphon principle or let the gasoline pump out by itself. Of course, no matter the method, pumping oil from a car's fuel tank is not a simple and easy operation. Below, we explain various pumping methods through the difficulty of operation.

First of all, prepare the tool, a section of sucker hose, 1cm in diameter; Containers for oil. Then drive the car to a place with a slope, because it is not easy to pump oil on the plane. After parking the car, the car is facing up, the gear is hung in first gear, and the handbrake is pulled.

After securing the car, open the fuel tank cap and put the sucker hose into the fuel tank, as far as possible to the bottom. When absorbing oil, it is not possible to use a hose directly, but also find a plastic bottle with a slightly larger diameter than the hose, flatten the plastic bottle in advance, and then connect the bottle mouth and the hose excuse tightly, use pressure to draw the oil out, and then pull the bottle off, and put the hose mouth against the container containing the oil. Of course, there are also special oil pumps for fuel tanks on the market.

Of course, no matter which method you use, pumping oil from a car's fuel tank is not an easy way to operate. Below, we explain various pumping methods through the difficulty of operation.

First of all, prepare the tool, a section of sucker hose, 1cm in diameter; Containers for oil. Then drive the car to a place with a slope, because it is not easy to pump oil on the plane. After parking the car, the front of the car is facing up, the gear is hung in first gear, and the handbrake is pulled.

After securing the car, open the fuel tank cap and put the sucker hose into the fuel tank, as far as possible to the bottom. When absorbing oil, it is not possible to use a hose directly, but also to find a plastic bottle with a slightly larger diameter than the hose, flatten the plastic bottle in advance, and then tightly connect the bottle mouth and the hose excuse, use pressure to draw the oil out, and then pull the bottle off, and put the hose mouth against the container containing the oil.

Hello dear, <>

Glad to answer for you, if you don't have a bottle or tools, you can try the siphon principle to pump out the oil from the tank. Put the other end of the hose into your mouth, and then suck firmly, and when you suck, you should control the strength and do not suck the oil into your mouth. When you see that there is oil in the tube and it is brought over, stop absorbing the oil, and then quickly take the hose out of your mouth and put it into the container containing the oil.

When pumping oil, look at the position of the oil surface in the container of the ridge of the wheel, and when you have pumped enough, pick up the hose from the container, let the oil in the pipe return to the fuel tank or lift the pipe from the fuel tank of the car, so that all the oil in the pipe flows into the container containing the oil, so as not to cause waste. <>

Fuel tank. Hope it helps, and I wish you a happy life!

The Besturn B70 fuel tank is made of plastic, the plastic fuel tank has good sealing, is not easy to deform, and is not very heavy, the biggest advantage is that the fuel tank of different shapes can be designed according to the model, so now the car uses plastic fuel tank.

The 2007 Besturn B70 has been discontinued. The official guide price of the 2007 Besturn B70 is 10,000 yuan. There are a total of seven models, which are divided into two emission standards: China IV and China III.

The Besturn B70 is a mid-size car. In terms of body size, the length, width and height are 4705x1782x1465mm, and the wheelbase is 2675mm.

There are two dynamics. The first is equipped with an inline 4-cylinder naturally aspirated engine mated to a 6-speed manual transmission or a 5-speed automatic manual transmission, with a maximum power of 108kW and a maximum torque of 183Nm.

If it is a car, the fuel tank is generally located under the rear seat, in the middle of the two rear wheels, and it can be seen when the bottom of the car is raised.

1. Generally, the fuel tank capacity of small cars is 35-45 liters, and the fuel tank capacity of medium-sized cars is about 55-75 liters. After filling up a fuel tank, it can generally travel about 500 kilometers, according to the displacement size of the car, the fuel tank with large fuel consumption is large, and the fuel tank with small fuel consumption is small. The volume of the car fuel tank is designed to generally travel 400 600 km.

For cars with light and small displacement, the fuel tank volume is correspondingly smaller; For cars with large vehicle weight and displacement, the fuel tank volume is naturally larger; But the maximum range with a full tank of fuel is mostly at 400 600 km. Except, of course, for some off-road vehicles.

2. How to look at the capacity of the car fuel tank.

1) Fuel tank capacity calculation unit: international standards are used l (liter) for the calculation unit of automobile fuel tank capacity, and there are corresponding standards for automobile fuel tank capacity in different countries. In China, it is stipulated that the car fuel tank capacity is rated at 95 percent, but the actual capacity is generally greater than the nominal capacity according to the actual situation, so there is no need to worry about the car fuel tank being smaller than the actual one.

Nowadays, many car fuel tank capacity is manufactured according to their own brand models, so some countries do not have corresponding car fuel tank capacity regulations. For vehicles that consume a lot of fuel, the fuel tank capacity of the car set by the brand will be larger, and the fuel tank capacity of the model with low fuel consumption will be smaller.

2) Now the car fuel tank capacity viewing method, generally through the car fuel gauge for reading observation, if there are no other problems the value of the fuel will be truly reflected on the fuel gauge. The fuel gauge of the instrument generally has 5-6 grids, and the amount of fuel in each grid represents the capacity of the remaining car in the fuel tank.
