Abstract
Systems and associated methods are for a marine drive and/or a marine generator The system has an engine, a temperature sensor configured to sense changes in temperature of oil for the engine, a speed sensor configured to sense changes in operational speed of the engine, and a control module configured to identify a presence of water in the oil by comparing the changes in the temperature of the oil to the changes in operational speed of the engine.
Claims16
A system for a marine drive and/or a marine generator, the system comprising:
- an engine,
- a temperature sensor configured to sense changes in temperature of oil for the engine,
- a speed sensor configured to sense changes in operational speed of the engine, and
- a control module in communication with the temperature sensor and the speed sensor, the control module being configured to identify a presence of water in the oil when said changes in temperature of the oil stagnate while said operational speed of the engine is at or above an engine speed threshold.
A method of identifying a presence of water in oil for an engine associated with a marine drive and/or a marine generator, the method comprising:
- sensing changes in temperature of the oil,
- sensing changes in operational speed of the engine, and
- identifying the presence of water in the oil by determining when said changes in temperature of the oil stagnate while said operational speed of the engine is at or above an engine speed threshold.
