Method for integrating fuel consumption amount of vehicles
First Claim
1. In a vehicle provided with an internal combustion engine, a carburetor which supplies fuel to said internal combustion engine, and a turbine-type fuel flow meter which detects the flow rate of fuel supplied to said carburetor, a method for integrating the amount of fuel consumption, comprising the steps of:
- summing the flow rate detected by said fuel flow meter at each prescribed time;
comparing a quantity relating to the vehicle speed in a mean value at said prescribed time with a given reference value;
selecting one from at least two prescribed correction factors based on the comparison and correcting the corresponding sum value of fuel flow rate by multiplying by the selected factor; and
integrating the corrected value of fuel flow rate.

Abstract
In a vehicle provided with a turbine-type fuel flow meter for detecting the flow rate of fuel supplied to a carburetor of an internal combustion engine, a method for integrating the amount of fuel consumption which comprises the steps of summing the flow rate detected by the fuel flow meter at each prescribed time, comparing a quantity relating to the vehicle speed in a mean value at the prescribed time with a given reference value, selecting one from at least two prescribed correction factors based on the comparison and correcting the corresponding sum value of fuel flow rate by multiplying by the selected factor, and integrating the corrected value of fuel flow rate. With such method, error based on the moment of inertia in a runner of the fuel flow meter is substantially eliminated.
