What is the reason why it is difficult to start the engine in winter?
It may be that there is too much carbon deposition: if there is a serious carbon deposition problem in the accelerator of the car, it is easy to block the airway of the car, so the owner will encounter the problem of cold start.
It may be the fault of the ignition coil: if the ignition coil leaks electricity, it is easy to cause the spark plug to reduce its ignition ability, and the mixture in the cylinder can not be fully burned, and then the car may have difficulties in starting.
It may be that the oil circuit is not smooth: with the decrease of temperature, the fluidity of vehicle oil becomes worse, and naturally there will be a phenomenon of sparking. You can change the engine oil that can adapt to low temperature, and it is best to use all synthetic engine oil.
It may be the lack of antifreeze: some car owners use inferior antifreeze when replacing antifreeze, or add water to replenish antifreeze, which will lower the freezing point of antifreeze, make the engine unable to work normally, and make it difficult to strike a fire.
It may be that the battery is insufficient: in winter, due to the influence of temperature, the battery will have low storage capacity. We can hit the car with electricity first, and then go to the repair shop to charge the battery. If it is too old, we can directly replace it with a new one.
