Technologies empowering efficiency 

LAVINIA, the electronically controlled E-PPN (Electronic Pump Pipe Nozzle) system, has been designed as an extension for existing mechanical injection systems. It centres around a magnetically actuated control valve that is integrated into the high-pressure fuel line in diesel engines. The LAVINIA E-PPN system expands the existing fuel system and can be used both for new diesel engines and for retrofits. Thanks to the precise actuation by a solenoid valve control unit, the system offers all the advantages of an electronic fuel control system to ensure optimised combustion under all operating conditions.

LAVINIA E-PPN Control Unit

HEINZMANN can provide a universal, electromagnetically actuated fuel control valve for diesel engines. It is used to precisely determine the fuel injection timing and quantity. As it has been designed as a module, it can be easily combined with existing high-pressure pumps and injectors from a wide range of manufacturers, negating the need for any major changes to the diesel engine. It comprises a complete extension kit for mechanical diesel fuel injection systems with individual plug-in pumps.

LAVINIA E PPN Control Valve

  • Enables the injection quantity and timing to be controlled electronically
  • Injection timing depends on the speed/load
  • Possibility to switch off the cylinders when idling or operating at low loads
  • Cylinder balancing
  • Up to 350 kW per cylinder
  • Up to 1600 bar system pressure
  • Suitable for retrofits and for new engines
  • Can be adapted to different fuel pump designs

E-PPN Control Unit MVC 01-24

The E-PPN control unit is based on the reliable, tried-and-tested DARDANOS solenoid valve control system. The MVC 01-24 is HEINZMANN’s most powerful electronic fuel control system and can actuate up to 24 cylinders. It features many inputs and outputs, making it easy to use on almost any diesel engine. Up to seven precise injections can be performed per cylinder and stroke. The large number of I/Os enables optimum engine operation and monitoring.

Speed sensors

Both inductive sensors and Hall sensors are available with different lengths and thread sizes. Thanks to their robust design, inductive sensors are ideal for use in harsh ambient conditions.
Compared to inductive sensors, the advantage of Hall sensors is that the output signal is independent of the speed and the distance from the sensor.
