Fuel-level detecting system for automotive vehicle
First Claim
1. A fuel-level detecting system for monitoring fuel consumption in an automotive engine and for detecting residual fuel in a fuel tank which defines a first fuel chamber being in communication with said automotive engine for supplying the fuel thereto and for receiving the fuel recirculating therefrom, and a second chamber being in communication with means for supplying the fuel to said first chamber at a supply rate irrespective of consumption rate of the fuel in said first chamber, said system comprising:
- a first resistor means, disposed within said first fuel chamber, for detecting a first level of the fuel in said first fuel chamber, said first resistor means having a resistance value variable depending upon said first level;
a second resistor means, disposed within said second fuel chamber, for detecting a second level of the fuel in said second fuel chamber, said second resistor means having a resistance value veriable depending upon said second level; and
means, associated with said first and second resistor means, for deriving a residual fuel amount indicative value based on said resistances of said first and second resistor means.

Abstract
A fuel-level detecting system for detecting residual fuel in a fuel tank includes two fuel-level detecting sensors, one of which is disposed within one chamber of the fuel tank, the other of which is disposed within the other chamber of the fuel tank. This system can more accurately detect actual fuel-level by indicating a value in accordance with current running through a closed circuit formed by the fuel-level detecting sensors and so forth.
