ТОПЛИВНАЯ СИСТЕМА


  1. CONSTRUCTION


    1. The supply pump consists of an eccentric camshaft, a ring cam, 2 plungers, 4 check valves, a Suction Control Valve (SCV), a fuel temperature sensor, and a feed pump.

    2. The 2 plungers are placed opposite each other outside of the ring cam.

  2. OPERATION


    1. Due to the rotation of the inner cam (eccentric camshaft), the outer cam pushes plunger "A" upward as illustrated below. The force of the spring pulls plunger "B". As a result, plunger "B" draws fuel in, and plunger "A" pumps fuel at the same time.
