摘要： A fuel control system for a cylinder injection type internal combustion engine which can avoid frequent changeover of engine control mode and ensure a sufficient vacuum level for a brake operating pressure while protecting against degradation combustibility and fuel-consumption performance of the engine without resorting to additional provision of a special circuit or device. The system includes an intake air flow sensor (2) for detecting an intake air quantity (Qa) fed to an internal combustion engine (1) for thereby outputting a corresponding information signal, a crank angle sensor (5) for detecting a rotation speed (rpm) (Ne) of the engine (1) and a crank angle thereof to thereby output a corresponding information signal (SGT), and a pressure sensor (17) for detecting a brake operating pressure (PB). A control unit (8B) of the fuel control system is so designed or programmed as to compare a vacuum level of the brake operating pressure (PB) with a predetermined level (PTH1) corresponding to a permissible upper limit value of the vacuum level to thereby control the engine (1) in a mode conforming to the engine operating state when the vacuum level of the brake operating pressure (PB) is lower than the predetermined level (PTH1), whereas when the vacuum level of the brake operating pressure (PB) becomes equal to or higher than the predetermined level (PTH1), the control unit (8B) controls the engine (1) in a stoichiometric mode to thereby allow the vacuum level of the brake operating pressure (PB) to be sustained lower than the predetermined level (PTH1).
