What are the reasons for slow acceleration when refueling?

[StCaden]

Here is a detailed introduction to the reasons for slow acceleration and lack of power when refueling: 1. Engine fuel system malfunction: The engine fuel system is a common problem area in cars. Issues such as clogged fuel injectors, fuel pipe leaks, reduced fuel pump power, or a blocked fuel filter can all cause the car to lack power when going uphill. The feeling of powerlessness mainly occurs because the engine does not have enough fuel during uphill driving, leading to decreased combustion efficiency and insufficient horsepower. 2. Using air conditioning in summer: In summer, small-displacement models may feel sluggish when accelerating with the air conditioning on, and fuel consumption increases significantly. This is because the air conditioning requires the compressor to be driven, and the compressor consumes a large amount of power. The engine has to carry such a significant internal load, which inevitably results in slow acceleration and a lack of power.
