Abstract
The invention provides a method for determining ignition quality in a fuel, the method including compressing a stoichiometric fuel mixture from a first pressure and temperature to a second temperature and temperature, and measuring the time between the attainment of the second pressure and temperature to auto ignition of the fuel mixture. Also provided is a device for measuring fuel ignition index, the device including a fuel mixture supply; a combustion chamber adapted to receive a stoichiometric fuel-mixture from the fuel-mixture supply; and a system for compressing the fuel mixture within the combustion chamber.
Claims20
A method for determining ignition quality, the method comprising:
- a. compressing a fuel mixture from a first pressure and temperature to a second pressure and temperature;
- and
- b. measuring the time between the second pressure and temperature and auto ignition of the fuel mixture.
A device for measuring fuel ignition index, the device comprising:
- a) a stoichiometric fuel-mixture supply;
- b) a combustion chamber adapted to receive a fuel-mixture at a first temperature and first pressure from the fuel-mixture supply;
- and
- c) a means for compressing the fuel mixture within the combustion chamber to a second temperature that is higher than the first temperature and to a second pressure that is higher than the first pressure.
