This problem occurs during actual engine failures. Most of the time, one cylinder does not work. Sometimes several cylinders may not work. If only one cylinder is not working, the more cylinders there are in the engine, the less obvious this is. the problem will be.
The main manifestations are:
First, the engine vibration amplitude increases, accompanied by abnormal sound, poor acceleration, and the exhaust pipe vibrates obviously, and there is an obvious intermittent feeling as the exhaust gases are vented. Pressing the accelerator will reduce the amplitude.
The oil content in the exhaust gas caused by the lack of cylinders seriously exceeds the standard, and the three-way catalytic converter must burn the exhaust gas containing oil, which will inevitably accelerate the deterioration of the catalyst. converter.
Why does the car stall automatically?ent as soon as I start the car? New car.
In addition to spark plugs, the highest failure rate is the combination coil that generates electricity in the high-voltage coil motor. Inspection Steps: 1. Remove the spark plug and cover it with a high voltage cap. Touch the spark plug to the metal shell of the engine and turn on the machine to check the performance of the spark plug. 2. Check the high temperature! Voltage coil and motor trigger coil. First use a multimeter to measure the impedance, and then measure the voltage of the high voltage coil on the machine. The output wire is red and black, and the trigger coil output wire is blue. and white. If there is no multimeter, the short circuit method can be used immediately. Normally there will be sparks caused by the short circuit! 3. Check the output voltage of the yellow wiresne and black from the igniter. You can also use the instantaneous short circuit method. Normally there are sparks caused by a short circuit. Check the igniter, disconnect the black and white wires, and check the spark plug for spark. The black and white wires are the wires from the dead light switch to the power door lock. When the electric door lock leaks, the igniter does not come out. high voltage. 4. The input wire of the high voltage box is the yellow and black wire. If there is voltage in the yellow and black wires, remove the high voltage cap and check for sparking in the high voltage wire. the normal distance between the high voltage wire and the motor shell is 0.5-0.2cm. Sparks appear when starting the machine.
Complete analysis of the causes of car stalling 1. Automatic transmission models: Automatic transmission models will not stall easily, whilee manual transmission models can often stall due to poor driving skills. However, it is not excluded that. cars with automatic transmission do not stall. The main reason is the use of substandard fuel (many gas stations sell impure oil in order to make huge profits), which causes carbon buildup in the engine and stalls. 2. In addition, the main reason for new car (automatic transmission) stalling is due to insufficient driving skills. Another possibility is the problem with the car's engine or oil system, but for new cars, the problem with the engine itself is more. probably small, the main reason is the oil circuit problem. 3. Finally, for older models, the cause of stalling is not only insufficient driving skill, but also the use of inferior oil quality.re which causes a build-up of carbon in the engine. Automatic Transmission Troubleshooting: Points to Consider in Daily Life: 1. The stalling phenomenon of automatic transmission cars is mainly caused by the use of inferior fuel. The first is to go to a larger service station to add premium oil, such as 97 grade gasoline. Although the price is much more expensive, it can guarantee a longer service life. long life to your car and good power while driving. However, some car owners try to get cheaper and add 90° oil even if the price is a little lower. Some, but problems may arise in the future. The second is to go to a large qualified service station to fill up! Actual operation: grip the steering wheel with your left hand to stabilize the steering (becausethere is no electric assistance, so you have to hold it firmly), brake hard with your right foot to reduce the vehicle speed as much as possible, and then quickly shift from AT gear to N gear (Note: change gear speed while driving) The ignition must be in N speed, not D/R/P, etc. Otherwise, the car will not start or the car's gearbox will be damaged), then turn the key back one click, then turn it back on, then turn the AT gear. Return to gear D for normal driving. Manual Transmission Troubleshooting: 1. For novices, stalling mid-shift is not a new topic. The main troubleshooting method is to quickly break in and improve their driving skills. 2. Use high quality, high quality and qualified fuel. 3. Thoroughly clean the oil system, including fuel injector, throttle, fuel tank, etc. It may be that the quality of the huThe oil you added is not up to standard and there is too much gum and grease, blocking the oil line and making it difficult for the oil to attack. 4. The cause of the car stalling at idle is mainly due to too much dust in the air. When the engine is running, a lot of dirt is deposited on the idle motor valve core and throttle seat. When too much dirt accumulates. the engine will idle too fast. If it is low, idle stability is poor and idle stalling will occur while driving. The solution to this problem is simple: just clean the engine at idle. 5. If the oil line is smooth, which can easily cause it to burn out halfway. 6. Due to rising gas prices and the return to cycling and walking to work, new cars are often parked and not used for a long time.th period. In fact, it is forbidden to park them for a long period of time. If the vehicle is parked for a long period of time, thorough maintenance should be carried out before reuse. Engine oil, engine filter, etc. must be replaced and the fuel, circuit, etc. must be checked if necessary. Your vehicle may have lubrication or electrical problems due to prolonged parking. In short, whether it is a new car or an old car, whether it is an automatic or manual transmission, whether you are a veteran or a novice, it is best to add a higher oil quality when refueling, even if it is more. expensive, it's worth it. This can protect your engine from carbon deposits. Additionally, regular maintenance is also crucial. Check if the oil lines and circuits are smooth.
