Mechanical inline pumps and VE rotary pumps are the two most classic fuel injection pump systems in traditional diesel engines.
1. Mechanical Inline Pump:
• One row of plungers, one plunger per cylinder.
• Representatives: B-osch PE, PW, P-type pumps; used in older Changchai/Xichai/Yuchai/Weichai engines.
• Structure: Plunger + Delivery Valve + Camshaft + Governor
2. VE Rotary Pump:
• Only one plunger, rotating to distribute fuel to each cylinder.
• Representatives: B-osch VE pump; favored in light trucks, pickups, small construction machinery, and 493/4JB1 engines.
• Structure: Single plunger, roller ring, advance mechanism, solenoid shut-off valve.
Application Scenarios (Most Practical Applications)
1. Mechanical Inline Pump – Heavy-Duty, High-Power
• Used in:
Heavy-duty trucks: Weichai, Yuchai, Xichai, C-ummins (older models)
Buses, buses, Large construction machinery, loaders, bulldozers, generator sets
• Multiple cylinder counts: 6, 8, 12 cylinders
• Features:
High pressure, high torque, durable
Cheap maintenance, many spare parts
Inferior precision compared to VE, but more robust
2. VE Distributor Pump – Light-Duty, High-Speed, Small Cylinder Count
• Used in:
Light trucks, pickups: 4JB1, 493, Jiangling, Qingling, Foton
Mini excavators, forklifts, agricultural machinery
Mostly 4-cylinder engines
• Features:
Small size, light weight, low noise
High speed, smooth operation
High requirements for diesel fuel cleanliness
