What's wrong with the car not catching fire in cold weather?
1. When the battery fails, the capacity of the battery will decrease at low temperature, and the starting voltage will be lower after the battery is used for a period of time. Solution: replenish the battery electrolyte or replace the battery with a new one in time. If the vehicle is not used for a long time, please take out the battery and put it in a warm place to avoid damaging the battery.
2. The flow rate of engine oil slows down, and the viscosity of engine oil in the car will increase at low temperature, which will slow down the flow rate, thus increasing the resistance of the engine and making it difficult to start the car. Solution: Use special oil in winter.
3. The exhaust pipe is frozen or the valve has too much carbon deposit. When driving, the engine is in the state of internal combustion, which will produce water vapor and cause dew condensation in some parts. If it doesn't melt for a long time, the car will definitely be difficult to start. Solution: Let the car drive at high speed and drain the water from the exhaust pipe. In addition, there is too much carbon on the valve, which is easy to block the throttle. It is recommended to clean the throttle regularly.
4. Engine failure. When the engine is seriously worn, the sealing performance decreases and the cylinder pressure is insufficient. It will also make it difficult to start the car. Solution: You can unscrew the spark plug, wipe off the oil stains between the electrodes and put them back.
5. If the engine freezes and cracks, adding water or inferior antifreeze to the car in winter will freeze and crack the whole water tank and waterway, and the engine will freeze and crack, causing the car water pump to fail to operate and catch fire, injuring other parts of the engine. Solution: Fill or replace antifreeze.
6. The performance of the spark plug is degraded, the ignition gap is too large, the ignition coil is aging, and the surface carbon is too much, which leads to the degradation of the ignition performance, which seriously affects the atomization combustion of the fuel and makes the ignition unable to start. Solution: Go to the 4s shop to check the cause and replace the spark plug if necessary. Million car purchase subsidy
