What is the reason for the BYD Qin's lack of power when stepping on the accelerator?
1 Answers
If the BYD Qin suddenly loses power when stepping on the accelerator while driving, it may be due to a fuel pump issue. You can test it by adding a fuel pressure gauge to dynamically observe whether the fuel pressure is normal when the vehicle malfunctions. It could also be caused by a clogged fuel filter or fuel injector, which may not change the fuel pressure but will significantly reduce the fuel supply. Below are additional details: 1. Accelerator: The throttle of a car engine is generally controlled by a pedal, also known as the accelerator pedal, which is a device used to regulate the fuel supply to the engine. 2. Operation Method: The operation of the accelerator pedal should use the right heel placed on the floor of the driver's compartment as a pivot point, with the sole lightly pressing on the accelerator pedal. The movement should be done by flexing and extending the ankle joint to press down or release. When pressing or releasing the accelerator pedal, the force should be gentle, ensuring a light press and slow release. When starting the engine, do not press the accelerator pedal all the way down; it is better to have it slightly above the idle throttle. When starting off, it is advisable to apply a bit of throttle just before the clutch engagement point, with the throttle opening set to a moderate level.
