1. A gaseous fuel analysis device comprising:
- a chamber containing a gaseous fuel;
a sound producing means in the chamber;
a sound receiving means also in the chamber;
means for measuring an acoustic property of the gaseous fuel communicating with the receiving means;
means for numerically relating an acoustic property of the gaseous fuel to a combustion property of the gaseous fuel; and
wherein the combustion property of the gaseous fuel is the anti-knock character.
