Abstract
The system is an on-board and in-line system for blending two fuels of known characteristics to achieve instantaneous in-line change in the octane rating of fuel flowing to the engine. The blending system provides a means of precise in-line blending of two reference fuels in an on-board aircraft or land vehicle installation. Based on appropriate calibration blending curves, the system will provide instantaneous indications of both lean and rich performance ratings of the fuel. Instantaneous lean and rich performance ratings of the blended fuel streams may be recorded concurrently with engine parameters and ambient test data, and with combustion knock severity numbers derived from the previously mentioned detonation indication system.
