Abstract
A device for reducing fuel dilution of a diesel engine may include an engine oil level sensor mounted to an oil pan for storing engine oil, to sense a level of the engine oil, a heater switch switched on by a signal of a controller, when the level of the engine oil in the oil pan is increased to a reference level or more by fuel diluted in the engine oil, and a heater connected to the heater switch in the oil pan, to evaporate the fuel diluted in the engine oil while being operated by an on state of the heater switch.
Claims6
A device for reducing fuel dilution of a diesel engine, the device comprising:
- an engine oil level sensor mounted to an oil pan for storing engine oil, to detect a level of the engine oil;
- a heater switch switched on by a signal of a controller, when the level of the engine oil in the oil pan is increased to a reference level or more by fuel diluted in the engine oil;
- and
- a heater connected to the heater switch in the oil pan, to evaporate the fuel diluted in the engine oil while being operated by an on state of the heater switch,
- wherein a barrier for storing a predetermined amount of the engine oil to be heated is integrally fixed with the oil pan on a wall surface of the oil pan to which the heater switch and the heater are mounted, and
- wherein a height of the barrier is equal to the reference level of the engine oil.
A method for reducing fuel dilution of a diesel engine, the method comprising:
- measuring, by an engine oil level sensor, a level of engine oil in an oil pan;
- turning on a heater switch in the oil pan, by a controller, when the level of the engine oil is measured to be a reference level or more;
- and
- evaporating and removing fuel diluted in the engine oil as a heater in the oil pan is operated by an on state of the heater switch,
- wherein a barrier for storing a predetermined amount of engine oil to be heated is integrally fixed with the oil pan on a wall surface of the oil pan, to which the heater switch and the heater are mounted, and
- wherein a height of the barrier is qual to the reference level of the engine oil.
