What is the fault of EFI motorcycle with unstable idle speed and easy flameout?
The unstable idle speed of EFI motorcycle may be caused by airway blockage, air leakage in intake manifold and sensor failure. The specific reasons are as follows: 1. Throttle body is blocked by carbon deposit: Throttle carbon deposit will affect the opening and air intake, which will make the engine speed unstable and accompanied by jitter after motorcycle starts. If the throttle is too dirty, it needs cleaning. Generally, the problem of unstable idle speed can be solved after cleaning. 2. The fuel pressure is too low, and the intake manifold leaks: for example, the fuel nozzle is blocked or the oil circuit is blocked, or the fuel pump pressure is insufficient, and the fuel pressure regulator and other faults lead to abnormal proportion of atomized mixture and incomplete combustion, which leads to unstable idle speed. If the intake manifold leaks air, it will affect the distortion of the feedback data of the intake pressure sensor, which will lead to the inaccurate control of intake air volume by ecu, resulting in abnormal mixture and unstable engine idle speed. 3. Sensor failure: The air-fuel ratio cannot be accurately controlled due to related sensor failures, such as air temperature sensor, oxygen sensor, throttle position sensor and intake pressure sensor.
