What is the difference between 'Open Loop' and 'Closed Loop'? A: When the engine is first started, and rpm is above 400 rpm, the system goes into 'Open Loop' operation. In 'Open Loop', the ECM will ignore the signal from the Oxygen (O2) sensor and calculate the air/fuel ratio based on inputs from the coolant and MAF sensors, but mostly from a pre-programmed table in the memcal. The system will stay in 'Open Loop' until the following conditions are met: 1. The O2 sensor has varying voltage output, showing that it is hot enough to operate properly. (This depends on temperature)
2. The coolant sensor is above a specified temperature about 40oC/104oF.
3. A specific amount of time has elapsed after starting the engine. The specific values for the above conditions vary with different engines and are stored in the mem-cal. When these conditions are met, the system goes into 'Closed Loop' operation. In 'Closed Loop', the ECM will calculate the air/fuel ratio (injector on-time) based on the various sensors but mainly the O2 sensor. This allows the air/fuel ratio to stay very close to 14.7:1.
A system which can exchange mass as well as matter with the surroundings is called anopen system.Example:- Heating of CaCo3 in an open bulb.A system which can exchange energy but not matter is called a closed system.Example:- Calcination of CaCo3 in a sealed bulb.
Flow process takes place in open system & non-flow process takes place in closed system.
an inlet has a closed end a straight is open both ends
a gate valve is a one way totally open or closed valve, a control valve is a variable valve.
Closed system implies that the system is under some pressure and the fluid is not exposed to the ambient air. Home systems are usually set at 12psi. An open system is exposed to the air with a holding or storage tank at the highest point. An open system needs to be built with parts and materials that will not corode ie; copper, brass, pex pipe, etc. ( do not use cast iron pumps, steel tanks or fittings) lc
A closed system does not allow for energy or matter to enter or leave the system.
they are different because one is open and the other is closed

We, as vertebrates, have a closed system in that our blood travels from the heart and back. Other organisms don't have such a system. Open circulatory systems allow all fluids in an organism to mix.
An open ventilation system simply lets the crankcase fumes vent into the atmosphere. A closed system reburns the crankcase fumes via the pcv valve.
the difference between open and closed population is that ...................................................................................................................................................................... go some where else to find the answer not on wiki awners.com
Grasshoppers have an open circulatory system, and worms have a closed circulatory system. There you go. :)

There is one major difference between an open DNS and a closed DNS. Open DNSs allow multiple users to connect easily while closed ones do not allow more users.
there is no difference. they are both 42.
