The objective of knock control strategies is to attempt to optimize the trade-off between protecting the engine from damaging knock events and maximizing the engine's output torque. Knock events are an independent random process. [8] It is impossible to design knock controllers in a deterministic platform. A single time history simulation or ...
To detect knock, a piezoelectric knock sensor (basically a microphone) bolted to the engine block responds to unique frequencies caused by engine knock. The sensor generates a small voltage that is sent to the electronic control unit , which processes the signal to determine if, in fact, knock is occurring.
In 1923 leaded gasoline is marketed, and by 1924 GM and Standard Oil Co. form the Ethyl Corp. Ethyl claims it has "solved" the problem of engine knock, but public health scientists (e.g. Alice Hamilton of Harvard University) are appalled at the prospects for lead poisoning and insist that alternatives such as ethanol blends are available.

The United States Food and Drugs Administration is warning pet owners about a common medication given to pets to treat arthritis. The F.D.A. now says that the drug Librela may be associated with ...
"Compared to a similar 2004 four-stroke engine, carbon monoxide emissions with Evinrude E-TEC are typically 30 to 50 percent lower; and at idle are lower by a factor of 50 to 100 times. In addition, Evinrude E-TEC emits 30 to 40 percent less total particulate matter on a weight basis than a similar “ultra-low emissions” four-stroke outboard.
Depending on the type, cheese isn't inherently unhealthy for dogs. But that doesn't mean it should be eaten with every meal. Like any other human food, cheese should be consumed by dogs in moderation.
