Title: Method of measuring air-fuel ratio
Inventor: JO HAN SEUNG
IPC: G01N27/16
Filed: 1998-12-28
Abstract: PURPOSE: A method of measuring air-fuel ratio is provided to measure the accurate air-fuel ratio with flame ionization density. CONSTITUTION: A flame ionization density is measured by injecting the gas of a mixer and an engine in measuring normal operation. In measuring the sudden acceleration/deceleration, an ignition signal is temporarily stopped without stopping the engine and the flame ionization density is measured by the same method. The air-fuel ratio is obtained from the measured value of flame ionization density depending on the running condition. The method solves the problem difficult to measure the air-fuel ratio in real time owing to the error in measuring or slow reaction speed through excessively discharged oxygen content.

In formula, M is titanium or zirconium; R R1 and R2 are the same or different C1-20 alkyl, alkenyl, alkynyl, aryl or alkalyl or halogen or ether substituted derivatives, additionally R2 is oxy derivatives or ether substituted oxy derivatives thereof; A, B and C are athoxy(ArO-), thioathoxy (ArS-), satisfyz+y+z = 3. The composition show characteristics of an impact resistance of more than 30 kg.cm/cm, a tensile strength of more than 550 kg/cm2, a coefficient of kinetic friction of less than 0.2 and abrasion loss of less than 1.
