Oil delivery system with oil temperature compensation control

A computer program that, when executed by a computer, causes the computer to:

• periodically acquire a temperature signal indicative of lubricant temperature of an outboard motor;
• adjust lubricant flow to an engine of the outboard motor based on lubricant viscosity as determined by the temperature signal;
• and
• wherein the computer includes a memory unit having therein a look-up table with data that correlates the temperature signal to a pulse width used to control a solenoid for adjusting lubricant flow to the outboard motor.

An outboard motor comprising:

• an internal combustion engine and a propulsion unit;
• an oiling system for the internal combustion engine having a closed loop re-circulation system that includes a remotely located oil reservoir and an oil flow control section that periodically diverts lubricant to the internal combustion engine;
• a temperature sensor to acquire a temperature signal having a relationship to a viscosity of the lubricant in the remotely located oil reservoir;
• and
• a control to receive and process the temperature signal from the temperature sensor and adjust the period that lubricant is diverted to the internal combustion engine in response to the temperature signal.

A method of providing lubricant to a two-stroke engine comprising:

• acquiring a temperature signal indicative of a temperature of a lubricant supply;
• correlating the temperature signal to a viscosity of the lubricant;
• adjusting lubricant flow to the two-stroke engine based on the viscosity of the lubricant;
• providing a closed loop re-circulation path for the lubricant such that when closed, no lubricant is routed to the two-stroke engine;
• periodically opening the closed loop recirculation path to route lubricant to the engine;
• and
• wherein the step of adjusting lubricant flow includes changing the period the closed loop is open.

A system to change lubricant flow to a two-stroke engine in an outboard motor comprising:

• a closed loop re-circulation path for the lubricant such that when closed, no lubricant is routed to the two-stroke engine;
• means for periodically opening the closed loop recirculation path to route lubricant to the engine;
• and
• wherein the means for adjusting lubricant flow includes changing the period the closed loop is open.

A method of providing lubricant to a two-stroke engine comprising:

• locating a lubricant supply remotely from the engine;
• acquiring a temperature signal indicative of a temperature of the lubricant supply;
• correlating the temperature signal to a viscosity of the lubricant;
• and
• adjusting lubricant flow to the two-stroke engine based on the viscosity of the lubricant.

A system to change lubricant flow to a two-stroke engine in an outboard motor comprising:

• a means for acquiring a temperature signal indicative of a temperature of a lubricant supply that is independent of engine temperature;
• a means for correlating the temperature signal to a viscosity of the lubricant;
• and
• a means for adjusting lubricant flow to the two-stroke engine based on the viscosity of the lubricant.
