【The owner's family car knowledge】What should we do if the EFI car engine fails? Next, let's take a look at the three major failures of the EFI engine. What should we do?
1. The steering stick cannot be pulled out from the P gear
The AL4 automatic gearbox will have a failure phenomenon that the driving joystick cannot be pulled out from the P gear. At this time, other gears cannot be engaged, and the car cannot move, and the driver will be very annoyed.Of course, it is useless to drive the joystick with a hard board. There is an ingenious way to pull the joystick: How to extend the service life of the engine valve train and modify the engine turbocharged air intake system.
a.Short-circuit the input and output terminals of the brake light switch;
b.Use a big screwdriver to obliquely insert into the locker to pull out the electromagnet, and quickly pull out the joystick;
c.Disassemble the central debris box, directly pull out the armature core of the lock driver, and pull the shift lever to the "N" position.
Of course, there is a prerequisite for troubleshooting this fault, that is, after stepping on the brake pedal, the brake light does not light up to be effective. If the "SPT" and "*" lights on the dashboard are flashing, it may be that the automatic transmission computer is damaged or the starting relay is prevented. At this time, the shift lever cannot be pulled out by the above methods.
2. Methods to eliminate air resistance
Air lock may also occur in the fuel supply system of EFI vehicles. Except for design reasons, the fuel tank and oil pipe are near high temperature areas, which are prone to air lock, which needs to be eliminated by traditional cooling methods with cold water and cold rags. Other EFI vehicles also have air resistance. For example, the Fukang EFI vehicle suddenly turns off during driving and cannot be started again.
At this time, you should turn on the switch, start it several times, and use the oil basin to catch the oil from the disassembled car filter nozzle until the foamy gasoline is drained. Just tighten the oil pipe, and it will tell you at the same time that when you refuel Do not press the white button in the fuel tank port to fill the fuel tank with oil, so that the gas in the fuel tank has no space to discharge. This kind of failure is most likely to occur in a taxi with a full tank.
3. Methods to prevent flooding
The Beverly Car drove in a torrential rain, and it was prone to flooding failures. The reason is that the suction port is located under the front and bottom of the water tank mask. The splashed muddy water is easily sucked into the cylinder from the suction port through the air filter, causing the cylinder to flood and damage the cylinder body. At the same time, when a sandstorm occurs in the north, due to the structural characteristics of the Fukang car, the dust can easily enter the air filter from the suction port and cause blockage and flameout.
Emergency method:In the sandstorm weather, it is very effective to clean the air filter element dust frequently, and it is also very effective to turn the suction port to the side. In rainy days, the speed of the vehicle should be controlled, the road should be selected, and the puddles and ponds should not be flushed. If the rainstorm lasts for a long time, simply temporarily remove the suction pipe from one end of the air filter, and install it after the weather is clear, which can effectively avoid tank flooding and smashing accidents.
