What Causes Difficulty in Starting a Vehicle?

[LeMadison]

Difficulty in starting a car is often caused by the battery, as in low temperatures, the car's power consumption is significantly higher than in other seasons, and the battery's capacity also decreases due to the cold environment. The reasons for starting difficulties are as follows: 1. When the engine is severely worn or malfunctioning, it can also cause starting difficulties. For example, after the cylinder and piston wear out, the sealing performance deteriorates, the amount of air entering the cylinder decreases, and the cylinder pressure drops. When the cylinder pressure is too low, the engine will fail to start. Another example is a damaged fuel pump or problems with the ignition circuit, which can prevent the vehicle from starting. 2. After the vehicle has been driven for some time, external dust and chemical reactions during combustion can cause some gummy substances to adhere to the fuel injector. These substances can block normal fuel injection, affecting the injector's sensitivity and leading to poor gasoline atomization. This results in delayed ignition, causing difficulty in starting the car.
