Delphi DP210 Rotary Mechanical Diesel Fuel Injection Pump

Product catalog summary

Overview
The Delphi DP210 Rotary Mechanical Diesel Fuel Injection Pump is an advanced mechanical alternative to electronic control systems, designed to meet U.S. Tier II and equivalent emissions standards. It builds on the technology of the Delphi DPA, DPS, and DP200 Series pumps, offering improved injection timing control, enhanced fuel/torque curve shaping, and better pump-to-engine timing.

Main Components

Fuel inlet with pressure variation and viscosity compensation
Transfer pump with pressure regulator
Four-plunger pumping element
Distributor system with reduced high-pressure volume
Internal cam ring with scroll plate filling control
Injection timing control with increased light load advance
Zero backlash drive shaft
Metering valve
Mechanical all-speed governor
Torque trimmer with excess fuel provision
Electric shut-off

Options

Clockwise or anti-clockwise drive
Boost control for turbocharged engines
Cold running injection timing control
Mechanical and electronic generator set governing
B20 and ultra-low sulfur diesel compatibility
Quick-fitting adaptors
Two-plunger design for low ratings
Timing overcheck feature

Benefits

Light load advance enhancements for emissions standards compliance
Torque curve shaping for higher torque backup
Solenoid actuated cold advance for low temperatures
Improved methods for measuring and setting injection timing
Industry-standard adaptors for quick-fitting connectors

Typical Applications
The pump is suitable for three-, four-, and six-cylinder engines in off-highway applications, both naturally aspirated and turbocharged, with or without charge air cooling.

Performance Advantages
The DP210 operates on the same principle as previous Delphi pumps, with fuel entering the pump and being pressurized for control of fuel quantity and timing. The system includes a maximum fuel curve shaping device and a governor for fuel control at lower loads.

The Delphi Advantage
Delphi is a leader in medium-duty diesel fuel systems, offering innovative solutions and a collaborative engineering approach. Their systems are designed to meet emissions requirements, improve fuel economy, and enhance performance, supported by a global network of resources.

Delphi DP210 Rotary Mechanical Diesel Fuel Injection Pump-2

Delphi DP210 Rotary Mechanical Diesel Fuel Injection Pump Benefits • Light load advance enhancements are designed to help meet U.S Tier II and equivalent emissions standards. Retarded full load injection timing reduces nitrous oxide (NOx) emissions, and light load advance travel capability to 28° engine maintains misfire margin at part load. The light load injection timing is set on each pump and the speed advance is controlled by a fixed stop at rated speed to provide advance consistency. The advance response rate is optimized to help prevent transient misfire. 3 Torque curve shaping provides...
