Fuel Injection Pump DBGVC631-1K for 248D Diesel Engine

Constructed with full mechanical structure without fragile electronic control parts, it has excellent shock resistance, high temperature resistance and oil pollution resistance. It runs reliably under harsh environments including bumpy construction roads, muddy farmland and rugged mountain roads, and tolerates poor-quality impure diesel fuel well with much lower failure rate than electronically controlled common rail pumps. The core plunger assemblies and delivery valves are made of high-hardness wear-resistant alloy via precision grinding, maintaining stable high-pressure sealing without internal leakage and extending service life.

• Built-in full-range mechanical governor ensures stable idle speed and overspeed fuel cut-off anti-runaway protection
• Accurate control of injection advance angle and fuel delivery for stable and responsive power output
• Heavy-load optimized fuel curve significantly boosts low-end torque for uphill climbing and overloaded startup
• Full mechanical design without electronic parts, superior anti-vibration performance for rough working conditions
• Wear-resistant alloy plunger and valve assemblies extend service life and reduce replacement costs
• Excellent thermal stability, consistent performance in high-temperature engine compartment
• High compatibility with low-grade dirty diesel, reduces vehicle fuel system filtration requirements
• Easy disassembly and overhaul, complete spare parts supply and low long-term operation cost
