What should I do if the gasoline is insufficient when the car is started by an external battery?

The cart starts. Cart start is the most familiar and effective emergency starting method, but this is a means of self-help, can not be used often, because this has a certain damage to the engine and clutch, automatic transmission vehicles especially to avoid this method of starting. It usually takes more than two people to start the cart, and it is difficult to start it if there is only one driver.

Before starting the cart, we should first observe whether the road conditions of the vehicle parking position are suitable for the cart to start, you can increase the speed with the help of the downhill road, if the front of the car is an uphill road, then the forward cart will be very tired, and the speed is difficult to increase, so you should turn the head of the cart downhill direction. Try not to start the cart on a road section with a lot of vehicles and pedestrians, so as to avoid accidents caused by improper response by the driver after the vehicle is started.

The ignition should be turned on before the vehicle is pushed, and when the vehicle reaches a comparable speed, the transmission should be put into gear, and then the clutch pedal should be quickly released and refueled. Once the engine starts, you should quickly press the clutch pedal while controlling the throttle so that the engine does not turn off, and then stop slowly.

Lap start. If there is a peer car in the event of a situation, and there is a jumper cable on the car, you can also use the battery lap method to start the vehicle. In this case, the two vehicles are brought close together until the jumper cables are sufficient to connect the positive and negative poles of the two batteries.

Care should be taken to ensure that the two vehicles are not in contact and only cables with sufficient load carrying capacity and insulated sheath are allowed. If the battery providing the power supply is not installed in a position on the vehicle that is convenient for direct jumping, the battery must be removed using a tool.

Determine the positive and negative electrodes of the two batteries, and use cables to connect the positive and positive electrodes, and the negative and negative electrodes respectively. It is necessary to pay attention to the positive and negative poles of the battery, and to ensure the reliable connection of the cable. Arrange the direction of the cable to prevent the cable from scratching with the tape or fan when starting.

Turn off all ancillary electrical equipment on the vehicle, start the vehicle where the battery providing power is located, and let the engine run for a few minutes to ensure that the battery is fully charged. Then start the non-electric vehicle in the normal way, and gently press the accelerator pedal after starting to make the engine run at 2000r min for a few minutes. Then turn off the ignition switches of the two vehicles, carefully remove the cables, and be careful to avoid the positive and negative cable joints colliding.

Traction starts. The method and principle of traction start are similar to those of cart starting, but the difference is that traction with a car is often much more labor-saving and trouble-saving. The specific implementation uses a tow rope of appropriate length, and the two ends are tied strongly.

Before towing, drivers of the front and rear vehicles should first determine the contact signals, such as whether to start and stop with a horn or a gesture, so as to coordinate and cooperate. To start slowly, the driver of the vehicle in front should pay attention to the traffic conditions on the road at all times, in addition to the direction of the vehicle behind him. The driver of the rear vehicle should signal the vehicle in front in time after the vehicle starts, and the two vehicles should slowly approach the side of the road to stop.

The car battery is insufficient, and the car can't be driven Emergency solutions:

1. The cart should be started forcibly with a gear, [the shortcomings should be more than 3 people to cooperate, the site should be open, the technology is required, and there is a certain degree of danger];

2. Trailer, forced start. [Need to find a car, have tools, open space, and have a definite damage to the towed three-way catalytic converter];

3. External car battery startup [need to find another car to connect the battery line or ask for a 12-volt battery];

4. Disassemble the faulty car battery to the repair shop for charging [it is very troublesome to disassemble the battery, and it has to be sent to the auto repair shop, and the waiting time for charging is very long].

Correct charging method of the battery:

1. First connect the positive pole of the battery to the positive pole of the power supply, and connect the negative pole of the battery to the negative pole of the power supply.

2. The initial charging competition is carried out in two stages: first, the initial charging current is charged until the electrolyte releases bubbles, and the single-grid voltage rises to the end. Then reduce the current to 1 2 initial charging current, and continue to charge until the electrolyte releases violent bubbles, and the specific and voltage are stable for 3 hours.

The full charging time is about 45 to 65h.

3. During the charging process, the temperature of the electrolyte should be measured often with the method of halving the current, stopping the charging or cooling, and the temperature should be controlled at 35 40. After adjustment, charge for another 2h until the specific gravity meets the specified level.

Replace it once every two or three years.

It is okay to add some oil when the battery voltage is insufficient. 1. In the no-load state, the normal voltage of the car battery is about 13V, and the normal load voltage is not less than 11V. Below this voltage, it may be difficult to start, after starting, due to the generator Jingkai slowly start to generate electricity, the normal voltage of the car battery should be between;

2. However, many battery cars and cars are now equipped with automatic alarms, so if they are not charged in time and continue for a long period of time, the cars and battery cars themselves will consume the remaining power, causing obstacles to the next start;

3. Therefore, if there are cars and battery cars that need to be parked for a long time at home, they need to be started every other week, and it should be noted that each start should last more than five minutes.
