A system for precisely measuring the amount of oil consumed during operation of an internal combustion engine includes a float chamber which communicates with an oil sump in the engine. A float is disposed within the chamber which moves upwardly and downwardly therein, depending upon the level of oil. A precision level detector is mounted in the upper end of the chamber for generating an electrical signal which is representative of the position of the float within the chamber. A microprocessor receives this signal, along with signals from various other sensors representing engine speed, engine torque, and oil temperature. In response thereto, the microprocessor controls the operation of a pump connected between an external supply of oil and the engine sump. When predetermined conditions are met, the microprocessor activates the pump to add oil from the system. The microprocessor also records the oil level over a period of time to determine the rate of oil consumption.

Oil consumption measurement system for internal combustion engine

A fluid flow system for delivering a fluid selectively from a supply tank and a scavenge tank to an internal combustion engine. The system includes pumping means for normally supplying the fluid from the supply tank to the engine and valve means for closing the output of the supply tank upon the presence of any fluid within the scavenge tank such that the pumping means supplies the fluid from the scavenge tank to the engine.
