Figure 2-7 - Catalytic Converter Efficiency vs Air/Fuel Ratio
The fuel rail assembly should provide controlled pressure and a steady
flow of fuel to the injectors. The fuel rail assembly must provide the
correct amount of fuel to each cylinder. Each fuel injector in the fuel rail
assembly should provide the correct amount of fuel, at the correct time
and place. Some compensation can be made within the engine software to
correct consistent cylinder-to-cylinder air/fuel ratio imbalances.
The evolution of US exhaust emissions legal limit is shown in Figure 2-8.
The continual reduction in legal exhaust emission limits places ever
greater demands on fuel delivery and control.
