The electrochemical behavior of horizontally disposed planar zinc in 30% (6.9M) potassium hydroxide, alone and saturated with zinc oxide at 25°C, has been investigated in a controlled manner, using both galvanostatic and potentiostatic techniques. The anodic characteristics have been interpreted in terms of a kinetically controlled process preceding a diffusion step. The cathodic behavior of oxidized zinc has been interpreted in terms of a complex two‐state process, involving the formation of a bound zinc hydroxide, followed by a reduction of both the adsorbed species and the soluble zincate to zinc metal.

“…The first half of the preignition period was dominated by pyrolysis and then peroxidation reactions. Jost and Martinengo [127] of Göttingen University detailed studies on an RCM of n-octane-air and iso-octane-air mixtures. They discussed, in general, the history of the RCM method, which they traced back to Nernst in 1906, along with contributions by Ricardo's collaborators Tizard and Pye.…”

Knock is one of the main limitations on increasing spark-ignition (SI) engine efficiency. This has been known for at least 100 years, and it is still the case today. Knock occurs when conditions ahead of the flame front in an SI engine result in one or more autoignition events in the end gas. The autoignition reaction rate is typically much higher than that of the flame-front propagation. This may lead to the creation of pressure waves in the combustion chamber and, hence, an undesirable noise that gives knock its name. The resulting increased mechanical and thermal loading on engine components may eventually lead to engine failure. Reducing the compression ratio lowers end-gas temperatures and pressures, reducing end-gas reactivity and, hence, mitigating knock. However, this has a detrimental effect on engine efficiency.Automotive companies must significantly reduce their fleet carbon dioxide (CO 2 ) values in the coming years to meet targets resulting from the 2015 Paris Agreement. One path towards meeting these is through partial or full electrification of the powertrain. However, the vast majority of automobiles in the near future will still feature a gasoline-fueled SI engine; hence, improvements in combustion engine efficiency remain fundamental.As knock has been a key limitation for so long, there is a huge amount of literature on the subject. A number of reviews on knock have already been published, including in recent years. These generally concentrate on current understanding and status. The present work, in contrast, aims to track the progress of research on knock from the 1920s right through to the present day. It is hoped that this can be a useful reference for new and existing researchers of the subject and give further weight to occasionally neglected historical activity, which can still provide important insights today.
