Function of the high-pressure pump

Posted on 3/14/2016 10:09:09 AM

The high-pressure pump plays an roles of compressing the fuel supplied by the electric fuel pump to the pressure required for high-pressure injection up to 20 MPa (200 bar). The fuel is metered with absolute accuracy by the high-pressure fuel injectors which is fitted to the fuel rail.In the other hand,it is atomized extremely quickly in high pressure.It will finally lead to the mixture preparation directly in the combustion chamber.

Technical characteristics:
Demand-controlled single-cylinder plug-in pump
System pressure up to Pmax = 20 MPa (200 bar)
High volumetric efficiency (85%)
Delivery rate up to 1,2 cm³/UCS
Integrated pressure relief valve
Variable pressure damper
Very flexible integration concept, hydraulic and electric
