Abstract
A fuel flow regulator for an internal combustion engine having an exhaust gas turbocharger is disclosed. The fuel flow regulator responds to intake manifold pressure. Thus the fuel flow regulator increases the maximum fuel flow to the internal combustion engine from a first maximum predetermined fuel flow rate when the intake manifold pressure is at a first predetermined intake air pressure level to a second predetermined maximum fuel flow rate when the intake air manifold pressure is at a second predetermined intake air pressure level. Additionally, the fuel flow regulator decreases fuel flow to a third maximum fuel flow rate which is less than the first predetermined maximum fuel flow rate when the intake manifold pressure is greater than the second predetermined intake air pressure level. Therefore, the fuel flow regulator protects the internal combustion engine from overboost of the engine by the turbocharger and for overfueling the engine.
