What if Cadillac doesn't catch fire in the morning?

Check the spark plug first. Because the spark plug is the key of the automobile ignition system, and the ignition system is the focus of the engine work, the performance of the spark plug is related to the working performance and efficiency of the whole vehicle.

Battery power loss-it shows that the starter starts to rotate but the speed is not enough, that is, it is weak, and then the starter clicks. When the temperature is low in winter, forgetting to turn off some electrical equipment will cause the vehicle to fail to start, especially when it is used at low speed for a long time in winter, the battery voltage will be lower than the rated value, and it will start abnormally and cannot work normally. If it happens, please call the service station for rescue, or find a car to check it, or catch fire temporarily, and then be sure to go to the service station to charge the battery.

The gasoline flow is blocked-characterized by no oil pressure in the engine oil supply pipe. This happens mostly in the morning when the temperature is extremely low, which is caused by the long-term uncleanness of the fuel pipeline. When the temperature is extremely low, water and sundries are mixed together, resulting in the fuel pipeline being blocked and unable to start. Emergency measures: put the car in a warm environment, and the car can start in a short time; Or completely solve it by cleaning the oil circuit.

The ignition system is in poor working condition-in extremely cold weather, the fuel can not be atomized well in the cylinder due to the low intake temperature. If the ignition energy is insufficient, the cylinder will be flooded, that is, too much fuel will accumulate in the cylinder, which exceeds the ignition limit concentration and the car will not start. Emergency method: Screw out the spark plug, wipe off the oil stain between the electrodes, and start the car after reassembly. The thorough way is to check the ignition system and eliminate the reasons of low ignition energy such as spark plug electrode gap, ignition coil energy and high voltage line state.

Valve glue-when using a car in winter, especially after using unclean gasoline, the glue in gasoline will not burn, but will accumulate near the intake and exhaust valves and combustion chambers. Drop some engine oil into the combustion chamber in the cold morning, which can usually be started. After starting, go to the service station for disassembly-free cleaning, and if it is serious, remove the cylinder head for cleaning.
