It basically means the fuel is being metered with MAP/MAF as the primary input. Once warmed up, fuel is metered by an active feedback loop with the O2 sensor, known as closed-loop operation. Share. WebOPEN-LOOP GAIN . Unlike the ideal op amp, a practical op amp has a finite gain. The open-loop dc gain (usually referred to as AVOL) is the gain of the amplifier without the feedback loop being closed, hence the name “open-loop.” For a precision op amp this gain can be vary high, on the order of 160 dB (100 million) or more. cinemas in penrith https://hotelrestauranth.com
