Unit Pump System (UPS)

Unit Pump System (UPS)


The Unit Pomp system is intended for diesel injection system.This system is directly related to Unit Injection System (UIS) and is used on commercial vehicles.Bosch was the first marketing producer of this technology in1995, in the world, which is also known as ''Unit Pump System''. The feature of the UPS is that each motor cyclinder has got its own unit pump. The system takes its shape of a composition of an integrated selenoid valve, a high pressure pump, a short fuel injection line, a pressure dispatch connection and a classical nozzle and injection file. The advantage of this system is to enable to achieve 2,200 bar of the injection pressures. In addition to this, the cylinder head do not need to be completely designed again while doing transformations on the classical ordered or from the distribution injection system. The motor manufacturer provides savings from the costs. And also the additional advantage of this system is being easy to change the damaged pump and valve units.Bosch, operates this Unit Pump Systems, particularly, for 92kW performance as per cylinder on 4 and 18 cylinders on commercial vehicle motors. If the cylinder piece is more than eight,than it needs a second control unit.
