Regulator injection timing

With the growth of the engine speed the fuel must be injected before, with the ignition, despite this, there is a set time. Adjusting injection timing controller performs injection. He is also set to pump.

If the engine speed increases, the pump shaft in the low-pressure pump rotates faster. The fuel pressure increases, which is used in controlling injection timing. The fuel pressure acts on the plunger and moves it against the spring force. The roller ring is rigidly connected with the plunger. With increasing pressure of fuel - as well as increased speed - piston pin roller moves it about its axis. The projections of the lifting disc is incident on the rollers before, that is, injection occurs earlier. When the piston speed is reduced and with it the roller ring moves back.
