Open Loop vs Closed Loop: Understanding Fuel Injection
Closed and open-loop conditions apply only to fuel-injected engines. Fuel-injected engines — basically, most motorcycles since the mid-2000s (and almost all that I buy) have sensors and fuel controllers. Not all fuel-injected engines have a closed loop mode, though. For example, the very first 1998-1999 Honda VFR800 operated only in …

DPF_LOAD is calculated using the pressure differential across the DPF etc, so is intended to represent the actual situation. The term'closed loop' means the input and output of the filter are both involved, so the system is a closed loop. DPF_SOOT is a calculated value based on various parameters like amount of fuel burned etc.

Introduction to open and closed loop control systems
The term 'open loop' means there is no feedback controlling the temperature of the heater. It will continue to get hotter with no adjustment, up to its maximum level, allowing you to keep the temperature at a set point. The open loop system is a simple design, the accuracy dependent on the calibration of the devices within the process.

In a closed-loop system, a line of communication is opened from the battery to the inverter/charger, allowing measurements to be taken directly from the battery's internal BMS sensors. When done properly, this eliminates the need for voltage-measuring shunts and provides an accurate baseline for charge/discharge decisions to be made.

The engine runs in "open loop" when first started, before the oxygen sensors come up to operating temperature. 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. Improve this answer.

Open loop vs closed loop
Open Loop and Closed Loop are two terms used to describe the fueling mode the computer is in. In closed loop fueling, the computer takes readings from the oxygen sensors which read +/- of 14.64 AFR (Stoich) and makes corrections for it. If your car is idling @ 13.5 AFR, the 02s can see this, and will know to pull out enough fuel to …
