Do not step on the gas door when starting the EFI car.

[Car World Maintenance] There will always be some minor problems in the car, and car maintenance is a technical activity. There are some places to pay attention to during the maintenance process. A lot, but some car owners like to deal with their own problems when they have problems in the car, but because they are not professional maintenance personnel, they often use some wrong maintenance methods to deal with their cars during the repair process, which often leads to their own Car injuries and injuries, the following editor describes some common car maintenance errors. Don’t oil the tire bolts and nuts in the wheel repair. In order to prevent the bolts and nuts on the wheels from rusting, a few private car owners will apply the lubricating oil to the bolts and nuts in the installation. It is not only wrong but also brings safety to the driving. Certain hidden dangers. After the bolts and nuts are tightened, they have self-locking characteristics. When the lubricating oil is applied, the self-locking coefficient between the two becomes smaller and the self-locking performance is degraded. When the car is driving at a high speed, the bolts and nuts are easily loosened or even detached, thereby causing a traffic accident. Do not wash the inside of the car with water. The summer is coming. Common private car owners wash the body with water and wipe it with a rag. Here, the private car owner should be reminded that it is best not to wash the water directly inside the body. Because the underside of the floor mat in the cab is not “all the horses”, the structural requirements are such that there are many grooves and through holes under the cab floor mat. After rinsing with water, it is either not deposited in the groove and is not easy to dry, or it flows from the through hole to the gearbox and the like to cause rust. Especially for cars with better sealing performance, it is not possible to directly flush the interior of the vehicle with water. The correct way is to wipe with a damp cloth, but avoid water. Different brands of coolant should not be mixed. Everyone knows that when the engine coolant is insufficient, it should be added in time. But do you use different brands of coolant together? If so, advise you to release the coolant as soon as possible. Add coolant from the same brand. Because the chemical properties of different brands of coolant may vary widely, such as effective preservatives for ferrous metals, they often corrode aluminum products; and preservatives for aluminum alloys are harmful to iron alloys. Because different brands of coolants use different preservatives, they cannot be mixed. Do not step on the gas pedal when the EFI car starts. It is a habit of many drivers to step on the accelerator before starting the engine, especially when the cold car starts in winter. But this method of starting is not suitable for EFI cars. The engine equipped with the electronically controlled fuel injection device is different from the common carburetor type engine. Its fuel injection control device can automatically adjust the fuel supply according to the temperature and working conditions of the engine to make the engine start smoothly, that is, when the cold car starts. The fuel injection control device can automatically increase the fuel supply. Therefore, when the engine of the EFI car starts, it is not necessary to step on the throttle, and it is not necessary to step on it continuously before starting, otherwise the engine will be started badly.
