Fuel control system for an internal combustion engine |
摘要 |
An i.c. engine fuel control system includes a closed loop roughness control, utilizing a roughness sensor circuit, an integrator which integrates the error between the roughness signal and a reference signal and modifies the fuel flow to the engine via a main fuel control with a variable frequency clock. During acceleration and deceleration the closed loop is interrupted by means of a circuit including two differentiators which are sensitive to throttle opening (speed demand) and actual speed respectively, and switches controlled by these differentiators.
