  • Device for measuring the load on a turbo-charged diesel engine, especially for regulating the injection timing in dependence thereon
    Patent number: 4538581
    Abstract: The invention relates to an injection regulator for adjusting the injection timing in a turbo-charged diesel engine depending on the engine speed and load. The regulator comprises a valve controlled by a centrifugal regulator and which produces an oil pressure varying as the square of the r.p.m., and a device loaded by the engine charging pressure. The oil pressure force and the charging pressure force are used to control a pair of slide valves, which regulate the oil pressure in a plunger-cylinder arrangement, by which the injection timing can be adjusted.
