PURPOSE: To control the supply of lubricating oil for an optimum amount by correcting basic valve opening signals calculated from the rotational speed of a compressor with detected signals for the temperature and the pressure of the lubricating oil, and sending driving pulse signals instructing a proper valve opening to a lubricating oil injection valve.
CONSTITUTION: A compressed air way 17 is connected to an air blast valve 16 injecting fuel into a combustion chamber 2 together with compressed air, the outlet 24 of a vane type air compressor 23 is connected to the compressed air way 17, and a lubricating oil supply unit 34 is provided on the intake 28 of the air compressor 23, and when an electromagnetic lubricating oil injection valve in the supply unit 34 is opened, the lubricating oil conveyed through a lubricating oil path 15 is supplied to the air compressor 23 as spray. Where, a temperature sensor to detect the temperature of the lubricating oil flowing in the lubricating oil injection valve, a pressure sensor to detect the pressure of the lubricating oil, and a rotational speed sensor to detect the rotational speed of the air compressor 23 are provided respectively. And an ECU 36 is made to send the lubricating oil injection valve driving signals to give proper valve opening for a specified amount of the lubricating oil flow corresponding to the rotational speed of the air compressor 23.
