What is the reason why Dongfeng Fengshen AX7 cannot accelerate when stepping on the throttle?
1 Answers
Reasons why Dongfeng Fengshen AX7 cannot accelerate when stepping on the throttle: 1. Clutch problem: If the engine speed increases when stepping on the throttle but the car does not move, it indicates a clutch issue. 2. Throttle cable problem: If the engine speed does not increase when stepping on the throttle, it means no fuel is being injected, which could be due to a fuel supply system issue or a throttle cable problem. 3. Intake system problem: When experiencing acceleration weakness, check if the intake system is intact. If it is, consider whether the intake system needs cleaning. Below are extended details on related content: 1. Power: Power is primarily generated by the intake system, fuel supply system, and related electronic circuits and components. Therefore, when acceleration is weak, these three areas should be checked to determine if they are affecting acceleration performance. 2. Avoid excessive throttle: Excessive throttle input only reduces driving time by 4%, but increases fuel consumption by 37%-40%. On typical city roads, the speed is usually maintained at 50 km/h, with engine speed around 2000-2500 rpm. On highways, speeds are generally between 90-110 km/h, and for every 10 km/h increase in speed, fuel consumption increases by 10%.
