Abstract
A system for displaying engine temperature information for a temperature control system in an internal combustion engine. A first temperature sensor senses the temperature of ambient air. A second temperature sensor senses the temperature of an engine oil. A third temperature sensor senses the temperature of a temperature control fluid. The sensors provide signals indicative of the sensed temperatures to an engine computer. The engine computer compares the sensed ambient air temperature to a first set of predetermined values to determine a desired engine oil temperature. The engine computer also compares the sensed ambient air temperature to a second set of predetermined values to determine a desired temperature control fluid temperature. A signal indicative of the desired engine oil temperature and/or the desired temperature control fluid temperature is output from the engine computer to a display system. The display system displays the desired and the sensed temperature signals. The display system may be incorporated into the instrument panel of a vehicle. Alternately the display system may be part of a testing apparatus for testing the operational state of the temperature contro…
