METHOD FOR CALCULATING THEORETICAL AIR TO FUEL RATIO IN MIXED FUEL OF GASOLINE, ALCOHOL AND ETHER, AND METHOD FOR PRODUCING THE SAME MIXED FUEL

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a mixed fuel of a gasoline, an alcohol and an ether, having a desired theoretical air to fuel ratio based on a method capable of obtaining a theoretical air to fuel ratio of the mixed fuel accurately.;SOLUTION: This theoretical air to fuel ratio of the mixed fuel of the gasoline, alcohol and ether based on the formula: 138.03×y/Wf. Provided that y is A+[B-(θ₁+θ₁+...+θ₇)]/2; Wf is a weight of the mixed fuel of the gasoline, alcohol and ether; A, B are each a factor of combustion produced gas ACO₂+BH₂O; θ_n (n: 1-7) are each volume % of the alcohol and ether-based fuels based on each of carbon numbers.;COPYRIGHT: (C)2003,JPO
