Performance Advantages
The basic operating principle of the Delphi DP210 Rotary Mechanical Diesel Fuel Injection Pump is the same as the highly successful Delphi DP200, DPS, and DPA fuel injection pumps. Fuel enters the pump and is raised to a pressure of about six bar for proper control of fuel quantity and timing.
Between injections, fuel is fed through a control (metering) valve into the distributor rotor center. At full fuel, the valve is held open and the pump delivers maximum fuel quantity. It is regulated by the maximum displacement of the pumping plungers and controlled by moveable scroll plates. A maximum fuel curve shaping device is designed specifically for each engine application to optimize fuel delivery at any engine speed. At lower engine loads, fuel is controlled via the governor, which throttles filling of the pipe.
During the pumping phase, the plungers are forced inward causing an injection pulse to travel from the pump to the injector in the engine cylinder via delivery valve and high pressure pipe. Timing of the injection is controlled or altered by rotation of the cam relative to the pumping plungers and drive shaft.

Delphi DPG Medium Duty Diesel Rotary Fuel Injection Pump
The Delphi DPG Medium Duty Diesel Rotary Fuel Injection Pump is based on the Delphi DPA series of diesel fuel injection pumps and includes mechanical governor enhancements, providing durable governor performance to ISO 8528-5 Class G2 standards. The pump is easily adjusted to suit either 50 or 60 Hz operation, and offers easy in-service conversion to electronic operation using an integrated governor controller and actuator. The main components of the DPG pump include:
- Fuel inlet
- Transfer pump with pressure regulator
- Distributor pumping system with two or four plungers
- Internal cam ring
- Driveshaft
- Metering valve with droop control
- Mechanical governor with low friction and wear features
- Governor transient stabilizer
- Electric shut-off
Options include:
- Advance control (start retard or light load advance)
- Clockwise or anti-clockwise drive
- Engine transient overspeed limiting
- Component package for low lubricity fuel
Benefits
- Enhancements to the design of the governor improve wear performance of the governor components, and advanced knife edge pivots and governor weight design improve hysteresis performance between governor pull-off and pull-on.
- Droop control sets droop (rate of governor pull-off) to a desired value and allows easy conversion from 50 Hz to 60 Hz generator operation within ISO 8528-5 Class G2 standards. This feature can also be used for in-service adjustments if required.
- Hydraulic damper fitted to the governor helps keep the alternator stable and within ISO specified requirements.
- A simple conversion to electronic governing with integrated governor controller and actuator allows in-service upgrades. No separate controller is needed, helping minimize wiring harness complexity. Digital control helps provide precise governing with multiple governing strategies such as isochronous load sharing, 50/60 Hz switching, auxiliary load sharing, etc. The actuator can be specified as original equipment by the engine manufacturer.
Typical Applications
The Delphi DPG Medium Duty Diesel Rotary Fuel Injection Pump is suitable for generator set and fixed speed applications within the following parameters:
- Engine rated speeds up to 3,000 rpm
- Engine ratings up to 24 kW per cylinder
- Peak pumping pressures up to 550 bar (injection pressures up to 650 bar)
- Three, four, or six cylinder engines
- ISO 6519 standard 20 mm diameter drive taper
- Gear or hub drive
- 12 V or 24 V electrical supply
- Up to 8° advance travel
Performance Advantages
The basic operation of the Delphi DPG Medium Duty Diesel Rotary Fuel Injection Pump is the same as highly successful Delphi DPA series of rotary fuel injection pumps. Fuel enters the pump and is raised to a pressure of about 6 to 7 bar for proper control of fuel quantity and timing.
Between injections, fuel is fed through a control (metering) valve into the distributor rotor center. At full fuel, the valve is held open and delivers maximum fuel quantity. It is regulated by the maximum displacement of the pumping plungers and controlled by adjustable plates. At lower engine loads, the flyweight governor controls the fuel by closing the control valve, which throttles the filling of the pump.
During the pumping phase, the roller shoe assemblies, which run inside the internal cam ring, are pushed inward. They bear on the pumping plungers in the rotor, causing an injection pulse to travel from the pump to the injector in the engine cylinder head via a pressurizing valve and high pressure pipe. Timing of the injection is controlled or altered by rotation of the cam relative to the pumping plungers and drive shaft.
Adjusting the trunnion throttle (which sets the load in the governor spring) sets the speed at which the governor reaches engine no-load delivery. Adjusting the height of the control metering valve sets the droop or governor speed range over which the governor reduces the fuel from maximum to minimum quantity. This changes the degree of overlap between the metering valve filling slot and the filling port in the hydraulic head, thus adjusting the angular rate of change of port area.

The Delphi DPGE Medium Duty Diesel Rotary Fuel Injection Pump is a fixed speed pump based on the Delphi DP200 Series of fuel injection pumps and includes mechanical governor enhancements providing durable governor performance to ISO 8528-5 Alternator Set Class G2 standards. The pump offers light load advance and is suitable for fixed speed applications which must comply with EU 2007 and U.S. Tier III exhaust emissions standards. The pump offers easy in-service conversion to electronic operation using an integrated governor controller and actuator. The main components of the Delphi DPGE Pump include:
- Fuel inlet
- Transfer pump with pressure regulator and viscosity compensation
- Distributor pumping system with four plungers
- Internal cam ring
- Driveshaft with locking feature
- Load Advance control
- Cold running advance for operation at low engine coolant temperatures
- Metering valve
- Mechanical governor with low friction and wear features
- Governor transient stabilizer
- Electric shut-off
Options include:
- Clockwise or anti-clockwise drive
- Bio diesel compatible component package
- Adaptors for quick fitting, low pressure connections
- Two-plunger design for low ratings and indirect injection (IDI) applications
- Timing overcheck feature
Benefits
- Enhancements to the design of the governor improve wear performance of the governor components and low friction pivots reduce hysteresis performance between governor load-on and load-off characteristics.
- A hydraulic damper fitted to the governor helps keep the alternator stable and within acceptable governing requirements.
- A simple conversion to electronic governing with an integrated governor controller and actuator allows in-service upgrades. No separate controller is needed, helping to minimize wiring harness complexity. Digital control helps provide precise governing with multiple governing strategies such as isochronous load sharing, 50/60 Hz switching, and auxiliary load sharing.
- Light load advance is designed to help meet EU 2007 and U.S. Tier III emissions standards for generator sets. Retarded full load injection timing reduces nitrous oxide (NOx) emissions, and light load advance travel capability to 20° engine maintains misfire margin at part load.
- The integrated wax-motor actuated cold advance helps prevent misfire when the engine coolant temperature is low.
- New methods of measuring and setting injection timing help meet emissions requirements. Once the pump is set, the drive shaft can be locked ready for installation on the engine.
- If required, the pump can be provided with a feature which allows factory timing setting to be over-checked or re-set.
- Available industry-standard adaptors for quick-fitting connectors provide low pressure system connection to the inlet and backleak of the pump.
- Optional elastomer seals throughout the pump enable bio diesel fuel compatibility.
- (Note: Bio diesel fuels are not recommended for installations that are used infrequently such as "stand-by" alternator sets, due to the unstable nature of the fuel.)
Typical Applications
The Delphi DPGE Medium Duty Diesel Rotary Fuel Injection Pump is suitable for three, four and six-cylinder diesel engines used for fixed speed applications such alternator sets (gen sets). It can be used on naturally aspirated and in turbocharged engines, with or without charge air cooling.
Performance Advantages
The basic operating principal of the Delphi DPGE Medium Duty Diesel Rotary Fuel Injection Pump is the same as the highly successful Delphi DP200 and DPA fuel injection pumps. Fuel enters the pump and is raised to a pressure of about six bar for proper control of fuel quantity and timing. Between injections, fuel is fed through a control (metering) valve into the distributor rotor center. At full fuel, the valve is held open and the pump delivers maximum fuel quantity. It is regulated by the maximum displacement of the pumping plungers and controlled by moveable adjusting plates. At lower engine loads, fuel is controlled via the governor, which throttles filling of the pump. During the pumping phase, the plungers are forced inward causing an injection pulse to travel from the pump to the injector in the engine cylinder via the delivery valve and high pressure pipe. Timing of the injection is controlled or altered by rotation of the cam relative to the pumping plungers and drive shaft.
