Diesel Engineering Services repair and calibrate the following Denso Injection Pumps:

 

Pump Type Common Denso Models Matching Injector Type Typical Applications Key Notes
In-Line Mechanical Pump Early Denso in-line (Bosch-licensed designs) Mechanical pintle or multi-hole injectors Older trucks, agricultural, industrial engines Very durable, mostly phased out in road use
Rotary Distributor Pump VE-type, ECD-V3, ECD-V4 Mechanical injectors (VE) or solenoid-controlled injectors (ECD) Passenger cars, light trucks, small tractors Compact, electronic versions allow precise timing
Electronic Unit Pump (EUP) Denso EUP systems Separate mechanical or solenoid-controlled injectors Medium- to heavy-duty trucks, buses One pump per cylinder, short high-pressure lines
Electronic Unit Injector (EUI) Denso EUI systems Unit injectors (pump + nozzle in one body) Heavy-duty trucks, marine, off-highway High-pressure, individual cylinder control
Common Rail High-Pressure Pump HP0, HP2, HP3, HP4, HP5, HP6 Solenoid or piezo common rail injectors Modern diesel cars, pickups, buses, construction Up to ~2,500+ bar, multiple injection events
Ultra-High Pressure Common Rail HP5+, HP6+ (next-gen) Advanced piezo injectors Newest emission-compliant heavy-duty engines Up to ~3,000 bar, extremely fine injection control
