Method of fuel injection control in diesel engines
摘要:
Methods and systems are provided for adjusting fuel injections provided to a cylinder when a fuel rail pressure deviation from a threshold pressure is detected. In one example, a method may include reducing a total number of pilot and/or main fuel injections provided to a cylinder in a given cylinder cycle in response to a reduction of pressure in a fuel rail. In this way, the threshold rail pressure may be maintained, reducing the likelihood the engine will be derated.
