Although many older drivers will recall their cars knocking when driving uphill on hot days,
the average driver under the age of fifty likely has never heard an engine knock. Indeed,

However, this does not mean that knock has been conquered. Rather, knock is a large issue that
continues to plague modern engine design, including impacts to the overall vehicle performance
and efficiency [1].
