Title:
FAILURE DIAGNOSTIC DEVICE FOR GASEOUS FUEL SUPPLYING DEVICE
Document Type and Number:
Japanese Patent JP3896692
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To diagnose failure of fuel pressure sensor by control means by providing the control means with a function for judging and informing failure of the fuel pressure sensor, in the case where an output voltage signal from a fuel pressure sensor is not in a prescribed region.
SOLUTION: An informing means 60 is connectingly installed on a control means 46. A function is applied to the control means 46 so as to control an operation of the informing means 60 by judging failure of the fuel pressure sensor 34 in the case where an output voltage signal from the fuel pressure sensor 34 is not in a prescribed region. The output voltage signal from the fuel pressure sensor 34 is inputted by the control means 46 to diagnose the failure of a gaseous fuel supplying device. It is thus possible to judge the failure of the fuel pressure sensor 34 by the control means 46, and it is also possible to improve a quality of control, and reliability of control.
