The Delphi DP310 Rotary Mechanical Diesel Fuel Injection Pump
is based on the Delphi DP210 Series. It is a viable alternative to
electronic control for diesel engine applications up to
approximately 129 kW that must meet EU Stage 3A, U.S. Tier III
and equivalent emissions standards. The DP310 Injection
Pump’s performance capability includes improved injection timing
control, enhanced fuel/torque curve shaping and improved pumpto-
pump timing.
The main components of the DP310 Injection Pump include:
• Fuel inlet with inlet pressure variation and fuel viscosity
compensation
• Transfer pump with pressure regulator
• Four-plunger pumping element with enhanced filling
capability
• Distributor system with reduced high pressure volume
• Internal cam ring with scroll plate filing control
• Injection timing control with increased light load advance
travel
• Cold running advance for operation at low engine coolant
temperatures
• Zero backlash drive shaft with increased shaft locking torque and improved timing accuracy
• Metering valve
• Mechanical all-speed governor
• Plus and minus torque trimmer with excess fuel provision
• Electric shut-off
• Transient advance control
Options include:
• Clockwise or anti-clockwise drive
• Boost control for turbocharged engines
• Mechanical generator set governing
• Electronic generator set governing conversion capability
• 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
• Snubber valves to attenuate return pressure waves in high pressure lines
