Engine actuated instrumentation and a fuel saving and diagnostic system based thereon
First Claim
1. In a system for automotive fuel cost tracking and engine diagnostic determination, a visual indicating means and a first recording register having means to connect with an engine and other means to mount the same within the view of the driver, said indicating means being movable from a position showing imminent, and then actual departure of the engine from a lean part throttle mixture to a rich full throttle mixture as the throttle is opened and the load on the engine is increased to a degree wasting fuel, and, for counting each occurrence of such throttle operation, and a second recording register with means connecting with the engine to record each engine start, said system including the step of determining accountability for poor miles per gallon by comparing the count on the first said register with the count on said second register.

Abstract
This system relies upon certain visual indicating and recording instrumentation which connect with an internal combustion engine and sense and record engine variables, including starts and loads. Visual indicating of these instruments by the operator of a motor vehicle so equipped encourage operation thereof in an economical manner. The recorded indications, when compared with each other give FER, a number indicating (Fuel Efficiency Ratio) which is a unique measurement of fuel efficiency and a tool to simplify diagnosis and cure of those instances of low miles per gallon of fuel.
