EGR works by recirculating a portion of an engine's exhaust gas back to the engine cylinders. This dilutes the O in the incoming air stream and provides gases inert to combustion to act as absorbents of combustion heat to reduce peak in-cylinder temperatures. NO is produced in a narrow band of high cylinder temperatures and pressures. Another primary benefit of external EGR valves on a spark ignition engine is an increase in efficiency, as charge dilution allows a larger throttle position and reduces associated pumping losses.

The right is preserved in the United Nations Universal Declaration of Human Rights and is granted formal recognition by the laws of most nations. Nonetheless the degree to which the right is upheld in practice varies greatly from one nation to another. In many nations, particularly those with authoritarian forms of government, overt government censorship is enforced. Censorship has also been claimed to occur in other forms (see propaganda model) and there are different approaches to issues such as hate speech, obscenity, and defamation laws.
