Did the old drivers who drove the car find a phenomenon, that is, often inexplicably unable to catch fire in the winter, anyway, Xiaobian remembers that when he was learning to learn the car, it was winter, he couldn’t catch fire, and he always turned off the fire. The technique of editing does not say that the cold winter is certainly one of the influencing factors. Then we know that the ignition is directly related to the ignition coil of the car. Then, in winter, this phenomenon of poor ignition is also related to ignition. What about coils?  

1. The temperature in winter is low and the viscosity of the engine oil is large. Therefore, the resistance is large at startup, and the starter is required to output a larger current.  

2. At the same time, when the car battery liquid is low temperature, the internal resistance is large and the voltage output is low; the starting voltage needs a larger voltage, and the voltage for other electric equipment will be lower. Generally, when the voltage of the ignition coil is lower than 8V, the ignition condition is Will be affected.  

3, the winter temperature is low, the mixture gas atomization is not good, need more ignition energy and voltage to ignite. Due to the increased ignition coil load, especially in winter, there is a higher probability of problems.  Then through the Xiaobian above, it is said that the ignition coil of the winter cold effect is still not comprehensive, because it only affects the engine, battery fluid and other components, and does not directly affect our ignition coil, but the impact of these components, ultimately It still caused our ignition coil to be affected, so there is still a certain relationship.
