Title:
ENGINE CONTROL DEVICE
Document Type and Number:
Japanese Patent JP3088539
Kind Code:
B2
Abstract:
PURPOSE: To prevent the defective restarting of the engine when the temperature of the engine is high without sacrificing the stable performance during the idling operation and the fuel consumption performance in order to eliminate the problems which may cause the deterioration of the fuel consumption during the idling operation and the increase of the vibrations and noises by increasing the idling speed when the engine is re-started when the temperature of the engine is high.
CONSTITUTION: A bypass passage which enables the communication between the upstream and the downstream of a throttle valve 4 is provided. An ISC valve 6 which is capable of arbitrarily controlling the sectional area of the bypass passage is provided, and the bypass passage is communicated by actuating the ISC valve 6 only when the temperature of the fuel exceeds the second set temperature.
