ABSTRACT:
A system for indicating, recording and evaluating a driving-data mode under three conditions of acceleration, speed maintenance and deceleration, in which the evaluated results are displayed on an LCD so that the vehicle is driven at a ¾ point of engine load capacity, serving as an acceleration point representing the maximum efficiency in designing a vehicle engine, at a ⅕ point of engine load capacity, serving as a static load point, and at a fuel-cutting point, thereby allowing the vehicle to be driven at the maximum efficiency point and maximizing a fuel efficiency. The system includes a fuel-injection amount-detecting unit, a maximum point-assigning unit, an engine idle driving fuel-injection amount driving point-assigning unit, ¾ and ⅕ point-assigning units, a fuel-injection amount cutting point-assigning unit, a fuel-injection amount display-indicating unit, a fuel-injection amount graph-regulating unit, and a liquid crystal display unit.
