Theory‎ > ‎  Detonation Engine  The detonation combustion mode
is superior to the deflagration mode used in today engines.
Detonation is efficient and so fast that no engine has yet stand

With our today Beau de Rocha (Otto) mode piston gas engine,
about half the gasoline used in the transportation sector is
literally wasted to fight the intake atmospheric vacuum
depression generated by the carburetor or injector manifold
butterfly-valve (The engine-braking effect). This is half the
pollution of the transportation activities.  The high RPM also
imposes constraints which require a reduced piston course, which
calls for a reduction of the crankshaft diameter and a reduction
of the engine torque, and consequently a more severe need for
the gearbox and on the kinetic aspects like the flywheel, which
severely reduces the engine accelerations. The modern
conventional engine fitted with a three-way catalyst can be seen
as a very clean engine. But it suffers
