Abstract:
1. A system for providing information to an operator of an engine such that engine performance can be optimized, comprising: a plurality of sensors adapted to measure operating parameters of the engine; an engine management system adapted to receive measured operating parameters from the sensors and to generate signals indicative of a current operating performance of the engine and signals indicative of performance-increasing adjustments to current operating parameters; and a display adapted to present symbols in response to signals from the engine management system, wherein the symbols guide the operator to increase or maintain engine performance; wherein the signals indicative of performance-increasing adjustments are generated based on comparison of measured operating parameters to a set of predetermined operating parameters that represent a two-dimensional engine torque-speed map having an area in which the engine operates with maximal fuel efficiency, and the area in which the engine operates with maximal fuel efficiency is an area of minimal brake specific fuel consumption.
