This way performance is kept at its optimum while mostly eliminating the risk of engine damage caused by knock (e.g. when running on low octane fuel). [5] An early example of this is in turbocharged Saab H engines, where a system called Automatic Performance Control was used to reduce boost pressure if it caused the engine to knock. [6]
The reduced engine speeds allow more time for autoignition chemistry to complete thus promoting the possibility of pre-ignition and so called "mega-knock". Under these circumstances, there is still significant debate as to the sources of the pre-ignition event. [3] Pre-ignition and engine knock both sharply increase combustion chamber temperatures.
This engine was the same model as that found in the UCF30 Lexus LS. The SC 430's V8 could produce 288 hp (215 kW) and 430 N⋅m (317 lb⋅ft) of torque, allowing the coupe to go from 0–60 mph in 6.2 seconds. [24] 2001–2005 Lexus SC 430
SC 430, SC430, or SC-430 may refer to: Konig SC 430 aircraft engine; Lexus SC 430 automobile; Santa Catarina SC-430, a highway in Brazil; South Carolina Highway 430, ...

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.
Work Completed: Engine performance problem resolved by replacing one of the VarioRam lifters in the intake manifold, shock absorbers replaced with custom-made coilovers complete with Wheeler Dealers logos on top of the strut mounts, brake backing plates and suspension drop links replaced, faulty rear spoiler mechanism fixed by replacing broken ...
Now TEL has been removed, we don't seem to have reverted to having a problem with knocking. How so? Was there never really a problem to solve or have we found a modern solution that renders TEL unnecessary? If so it isn't discussed here. Atconsul 16:28, 9 October 2023 (UTC) The potential problem of detonation remains as high as ever.
