GM > Engine > Fuel Control > Open & Closed. Open and Closed Loop The VCM fueling generally operates in one of three modes: 1) Open loop, 2) Open loop STFT or 3) Closed Loop. Open loop is used when the O2 sensors are not warmed up, failed, or when an enrichment mode (such as power enrichment) is active.

Fuel Sys Open/closed Loop Car Forums and Automotive Chat

Jan 23, 2006 · Note that there are 2 kinds of open loop. Right after a cold or hot start, a scan tool will report that the PCM is using open loop fuel control. This version of open loop is described in the next section. Once the PCM decides that conditions are right, it switches to closed loop fuel control, which is described below the open loop discussion.

Grinding in Ball Mills: Modeling and Process Control

In order to achieve the desired particle size, the milling under industrial conditions is usually performed in grinding circuits including classifiers that separate the material according to particle sizes. The simplest cases of open and closedcircuit systems are shown in Fig. 1. Fig. 1

Openloop controller Wikipedia

In an openloop controller, also called a nonfeedback controller, the control action from the controller is independent of the "process output" which is the process variable that is being controlled. It does not use feedback to determine if its output has achieved the desired goal

Closed, Open, and Short Circuits dummies

You need a closed path, or closed circuit, to get electric current to flow. If there's a break anywhere in the path, you have an open circuit, and the current stops flowing — and the metal atoms in the wire quickly settle down to a peaceful, electrically neutral existence. A closed circuit allows current to []

What is the difference between an open and close circuit

Dec 14, 2006 · Best Answer: It depends on what kind of system you are talking about. In electronics or electrical engineering, an "open" circuit means there is no path for the electricity to flow through it is "turned off". A "closed" circuit means there is a full path for the electricity to flow through, so that it

Openloop System and Openloop Control Systems

Then an Openloop system, also referred to as nonfeedback system, is a type of continuous control system in which the output has no influence or effect on the control action of the input signal.In other words, in an openloop control system the output is neither measured nor "fed back" for comparison with the input. Therefore, an openloop system is expected to faithfully follow its input
