The first outside-shelf feeder duct feeds first regulating air that is air for regulating environmental conditions around the commercial products and regulated at a first condition.

Both controlling surfaces of the piston are exposed to controlling air.

The multi-cylinder internal combustion air/fuel control device can execute an accurate air/fuel ratio control.

An air-fuel ratio control apparatus for an internal combustion engine is provided.

The present system (12) reduces the formation of NOx within the combustion zone by controlling the air/fuel ratio and more explicitly by controlling the air portion of the air/fuel ratio.

A binary lambda controller can output a controller actuation signal (LAM_FAC_FB) for controlling an air/fuel of ratio (LAM) in the combustion chamber (26).

The device includes an air/fuel ratio sensor, air/fuel ratio control means and a detection unit.

A metal-air power supply which provides improved control over air flow is provided.

Disclosed is an air-fuel ratio control device for an internal combustion engine.

The control unit controls an actuator for air volume control according to the target air volume while at the same time controlling an actuator for fuel injection volume control according to the target air-fuel ratio.

This allows, in medium speed/medium load operation, fine EGR rate control and air-fuel ratio control.

An integrated environmental control system (10) is disclosed for providing conditioned supply air to loads such as a passenger cabin (56) of an aircraft.

Disclosed herein is a method of controlling the air to fuel ratio in a burner containing a venturi assembly.

Regulation levels include translational regulation, transcriptional regulation, mRNA stability regulation, and mRNA transport regulation.

The regulating circuit converts between current regulation and voltage regulation.
