Abstract
Methods and systems for adjusting timing of fuel injectors to reduce cylinder to cylinder air-fuel maldistribution are disclosed. In one example, fuel injection timing is adjusted as a function of pressure ratios that are based on fuel rail pressures observed during injection of fuel. The pressure ratio may be a ratio of a root-mean-square pressure and a scheduling fuel pressure.
