Octane Number Requirement Survey of 1998 Japanese Model Passenger Cars

摘要

The Sub-Committee of Octane Number Requirement (ONR) of the Japan Petroleum Institute conducted a 1998 ONR Survey to estimate the maximum ONR distributions for 1998 model cars on the road by use of maximum ONR data compiled from 151 test cars. The maxiumum ONR data were determined by means of the low speed test method using both Primary Reference Fuel (PRF) and Full Boiling Range Reference Fuel (FBRRF). The results of the 1998 ONR Survey are summarized below, together with pertinent information on test cars, test fuels, test method for ONR measurement and calculation procedure for determining maximum ONR distribution.
