Abstract
Methods and systems for adjusting fuel injection of an internal combustion engine are disclosed. In one example, a change in fuel pressure is scheduled when a number of pilot fuel injections provided by a fuel injector to a cylinder transitions from a first number during a first engine cycle to a second number during a second engine cycle. The methods and systems may reduce engine emissions and improve engine noise characteristics.
