an oblique detonation as a wave where the pressure field generated by combustion behind the wave influences the wave itself. This influence is manifested in a rotation of the oblique wave to a more normal orientation. The limiting case is an oblique Chapman-Jouguet detonation where the normal velocity component behind the wave becomes sonic.

Detonation: Detonation is an uncontrolled, explosive ignition of the fuel/air mixture within the cylinder''s combustion chamber; Caused by hot engine temperatures; or using a lower than recommended fuel grade; It causes excessive temperatures and pressures which, if not corrected, can quickly lead to failure of the piston, cylinder, or valves
Funny thing was, I was about 15 feet away when it happened. When the coach is parked, I rarely am on the battery side of the coach, but just happened to be working on a tire on that side at the time. Just about gave me a heart attack. 2 batteries in parallel, if one battery has a cell that shorts, there is a lot of current and a lot of heat.

Detonation Pressure Wave Analysis: A Comprehensive Guide
Understanding Detonation Pressure Waves. Detonation pressure waves are the result of the rapid release of energy during the detonation of high-energy explosives. These pressure waves can reach peak pressures of up to 40 GPa (400,000 atm) and propagate at supersonic speeds, typically ranging from 5,000 to 9,000 m/s.
