Unit pump system in UAE

The Unit Pump System is a high-pressure fuel-injection system specially designed for commercial vehicles. As with the Unit Injector System, each engine cylinder has a single-cylinder pump with integrated solenoid valve. This is connected to a conventional nozzle-holder combination via a short high-pressure line. This construction allows fuel-injection pressures of up to 2,200 bar.

The Unit Pump System is used for commercial-vehicle engines with performances of different cylinders. The electronic control unit can trigger a system comprising a maximum of eight cylinders. A second control unit allows the system to be extended to 16 cylinders.

The benefits of Unit Pump Systems are Low emissions, Favorable fuel consumption, Easy conversion from fuel-injection systems with in-line or distributor pumps (no need to redesign the cylinder head) and Simple and fast customer service as the pumps can be exchanged easily
