Abstract
PURPOSE: To provide a controller for finely controlling the fuel injection timing in accordance with various driving conditions.
CONSTITUTION: A first pressure chamber 18 is formed to face one end portion 17a of a timer piston 17 and is supplied with an oil pressure proportional to the r.p.m. of an engine from the discharge pressure side 19 of a fuel supply pump 3 through an oil pressure passage 17b formed in a timer pistion 17 as well as through an oil pressure chamber 6. A second pressure chamber 20 is also formed to face the other end portion 17c of the timer piston 17 and is supplied through an oil pressure passage 22 with the discharge pressure of the fuel supply pump 3 which is adjusted to the most proper level by means of a variable throttle 21. This throttle 21 is composed of a valve piston 21b and is operative to open the valve piston 21b in response to the signals from respective sensors thereby to actuate the timer piston
