SYSTEMS AND METHOD FOR DIAGNOSIS OF MISSING FUEL INJECTION

摘要

A fuel control method for a vehicle, the method comprising: applying power to a fuel injection valve of an engine for a fuel injection event; measuring first and second voltages at first and second electrical connectors of the fuel injection valve; a maximum value based on a first difference between the fuel injection valve determining a minimum value based on the first difference between the first and second voltages; determining a second difference between the maximum value and the minimum value; and indicating whether the fuel injector has injected fuel in response to the application of power based on the second difference between the maximum value and the minimum value.
