Abstract
An oil temperature compensation control is disclosed for use with an oil delivery system in an outboard marine engine. The control includes an oil injection system that normally routes lubricant through a closed loop, and periodically diverts lubricant to the engine. The control includes a temperature sensor to acquire an oil temperature indicative signal, which preferably, is an indirect measurement of oil temperature. The control includes a microprocessor connected to receive the oil temperature indicative signal, and in response thereto, to control the period lubricant is routed to the engine by the oil injection system. The microprocessor includes a memory to store a look-up table that includes a solenoid pulse width for a variety of temperature signals so that the solenoid can be toggled based on the viscosity of the oil to provide proper lubrication to the engine regardless of external temperatures.
