Abstract
An oil dilution inhibiting apparatus is configured to inhibit oil dilution caused by mixture of fuel into engine oil. The oil dilution inhibiting apparatus includes a control unit. The control unit is configured to estimate friction of an engine and determine that the oil dilution occurs when the friction of the engine is decreased to a value lower than or equal to a predetermined threshold value to perform control so that the engine is operated at a higher speed.
Claims9
An oil dilution inhibiting apparatus configured to inhibit oil dilution caused by mixture of fuel into engine oil, the oil dilution inhibiting apparatus comprising:
- a processor;
- and
- a memory having programs, when executed, causing the processor to be configured to:
- estimate friction of an engine;
- determine that the oil dilution occurs when the friction of the engine is decreased to a value lower than or equal to a predetermined threshold value;
- and
- in response to determining that the oil dilution occurs, control the engine to operate at a higher first rotational speed set to be above a second rotational speed at which the oil dilution is detected.
