BOURKE HISTORY

Bourke designed his engine to fulfill the five desirable attributes for an efficient internal combustion engine laid down by de Rochas a century ago

BOURKE ENGINE

Bourke Engines contradict typical design, they use detonation as a means of extracting more energy from each pound of fuel
