摘要： A fuel control system for an internal combustion engine includes a fuel starvation detection module and a fuel pump protection module. The fuel starvation detection module detects when a fuel pump is delivering less than a predetermined amount of fuel based on a fuel level in a fuel tank, a fuel pressure in the fuel pump, and an air/fuel (A/F) ratio of the engine. The fuel pump protection module decreases an amount of fuel supplied to the engine during a period after detecting that the fuel pump is delivering less than the predetermined amount of fuel.

摘要： An engine control system for a vehicle comprises a combustion control module and an engine startup module. The combustion control module selectively controls a spark timing and airflow into an engine based on a counter value. The engine startup module, when the counter value is one of greater than and less than a predetermined final value, controls an equivalence ratio (EQR) of an air/fuel mixture provided to the engine during an engine cranking period based on a fuel rail pressure and controls the EQR during an engine running period based on the fuel rail pressure and an engine runtime period. The counter value is set to the predetermined final value after the engine is started for a first time after the engine is assembled.
