Is it related to the cold weather and the car not catching fire?

The factors that affect the engine start are: air intake system, oil supply system, ignition system, lubrication system, etc.

Air intake system: when the weather turns cold, fuel is injected into the air intake pipe, and the atomization effect is not good. If there is carbon deposit in the engine intake system at this time, part of the fuel in the mixture will be adsorbed, and the mixture will not be easily ignited in the cylinder. Then you can consider cleaning the engine intake and throttle at this time.

Oil supply system: it is difficult to build oil pressure in the oil supply pipe of the engine, which often happens in the morning when the temperature is extremely low. When the temperature is extremely low due to the dirty fuel pipeline or nozzle, the fuel pipeline is not smooth due to the mixing of water and fuel, and as a result, it is difficult or impossible to start. The solution is to completely solve the ignition failure by cleaning the oil circuit.

Ignition system: In cold weather, if the ignition ability is too weak, it is difficult to ignite the mixture with poor atomization effect. At this time, we should consider checking whether the spark plug is aging and whether the ignition coil is aging. In addition, when the weather is cold, the capacity of the battery will become low. We can judge whether the battery is dead by electrical equipment such as lights and speakers.

Lubrication system: at low temperature, the viscosity of engine oil will increase, the flow of engine oil will become difficult, the resistance of engine starting will also increase, and it is naturally difficult for the car to ignite. Therefore, it is more suitable for us to use low viscosity engine oil in winter.
