Abstract
A gaseous fuel analyzer having a flow through chamber equipped with sound producing means at one end and sound receiving means at the other for measuring an acoustic property of fuel flowing through the chamber and for numerically relating the acoustic property to the combustion character of the fuel.
Claims26
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.
