Engine Control Device

摘要

An engine control device sets a target value for the engine oil temperature appropriately in an engine that uses gasoline as a fuel, even when the fuel does not have a single boiling point because the gasoline is a mixed composition, or when the fuel property changes (for example, when the vaporization property changes due to deterioration). In other words, the engine control device prevents excessive heating or insufficient heating by changing the oil temperature to the high side in a condition wherein the fuel being used does not easily vaporize, and changing the oil temperature to the low side in a condition wherein the fuel being used easily vaporizes. This engine control device includes an oil temperature controller that controls the temperature of oil lubricating the interior of the engine; a fuel supply device that supplies fuel to the engine; and a detector for detecting the property of the fuel. The temperature of the oil is controlled on the basis of a signal from the detector.
