The Delphi DP210 Rotary Mechanical Diesel Fuel Injection Pump
is based on the Delphi DPA and DPS pumps, as well as the more
advanced DP200 Series. It is a viable alternative to electronic
control for diesel engine applications that must meet U.S. Tier II
and equivalent emissions standards. The DP210 Injection Pump’s
performance capability includes improved injection timing control,
enhanced fuel/torque curve shaping, and improved pump-to-engine
timing. The main components of the DP210 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 filling control
• Injection timing control with increased light load advance
travel
• Zero backlash drive shaft with increased shaft locking torque and improved timing accuracy
• Metering valve
• Mechanical all-speed governor
• Torque trimmer with excess fuel provision
• Electric shut-off
Options include:
• Clockwise or anti-clockwise drive
• Boost control for turbocharged engines
• Cold running injection timing control for operation at low engine coolant temperatures
• Mechanical generator set governing
• Electronic generator set governing conversion capability
• B20 and ultra low sulphur 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
